Answer:

Bacteria have smaller populations, grow faster, and also share more genes compared to mammals.

Explanation:

Because bacteria reproduce quicker and are also in smaller populations, they can evolve quicker because more genes are shared which can be helpful. This is due to natural selection, which will affect bacteria more than mammals because their small populations will make natural selection more significant to  be harmed by mutations and allow them to evolve.

Colonial protists have been hypothesized to be the precursors to multicellular organisms. This hypothesis suggests that the individual unicellular members of the colony, which are initially identical, can begin to take on different functions. Then. the colony can begin to evolve into a multicellular organism. True or False

Answers

Answer:

True.

Explanation:

Protists are group of eukaryotes that are unicellular or microscopic and some times multicellular. They can live in colonies and live individually.

Some protist live in large groups called colony.

Colonial protists form larger groups of multicellular organisms. The individuals work together as large groups and perform functions to benefit each other.

most of the colonial protist are filter feeders that feed on suspended particles. Colonies enhance feeding efficiency. In choanoflagellates, coloniest has led to the evolution of metazoans

The fruit fly Drosophila melanogaster is an important model system for studying inheritance in animals and genetic control of animal development, including humans. Evaluate Drosophila as a model system for human biology. What are their strengths and weaknesses as a model system? g

Answers

Answer:

The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"

Explanation:

The fruit fly Drosophila melanogaster is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.

While doing research on deep-sea vents, you discover a very simple new life form. After some initial analysis, you find that this life form contains small fragments of DNA, small complementary RNA fragments, and proteins. Fortuitously, you collected two strains, one that is purple and one that is yellow. You wish to discover which of those three molecules could be the genetic material. You heat-kill some of the purple life form and subject three different homogenized samples to different enzymes: DNase, RNase, or protease. Which treated sample(s) will transform yellow into purple IF RNA is the genetic material

Answers

Answer:

The one treated with DNase and protease

Explanation:

The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with DNase and protease respectively.

The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.

The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.

Explanation:

Gel electrophoresis is an amazing technique that allows for DNA separation based on size (as in, length). Using electricity (and keeping in mind that DNA has a negative charge because of the phosphate groups), the shortest pieces will migrate the farthest.

So we can tell that the pieces are in ascending order of size. 4>3>2>1, in length.

A. Strand 1 is the smallest.

Answer:Given results of gel electrophoresis shows that strand 1 is smallest. The pieces are arranged in ascending order of size 4>3>2>1 . Thus,option A is correct.

Explanation:

What is Gel electrophoresis?

Gel electrophoresis is a laboratory technique used to separate mixture of DNA ,RNA or protein according to their molecular size.

The gel used in this technique is composed of polyacrylamide or agarose.

The main application of gel electrophoresis has been in the seperation of molecules and in restriction mapping.

The main advantage of gel electrophoresis is its capability to

simultaneously separate various samples in one round.

Therefore, strand 1 is the smallest according to the result of gel electrophoresis  shown in figure. Thus, option A is correct.

Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine

Answers

The given question is incomplete, the complete question is:

Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine. If the nitrogen ingested in food is 100 g/day, but only 80% of the food is actually absorbed, while the rest goes to waste, what is the amount of nitrogen lost by excretion? Assume steady-state. Of the nitrogen liberated from muscle, 90% is excreted, while the rest is recycled, what fraction of the nitrogen entering the muscle is from the absorbed food? (In other words, what is the ratio A/(A+R)). Again, assume steady-state

Answer:

The amount of nitrogen lost in the process is 20 grams in a day and the fraction of nitrogen entering the muscle is 0.909.

Explanation:

Based on the given question, the amount of nitrogen absorbed is 80 percent of 100 grams, that is,  

100*(80/100) = 80 grams in a day.  

The concentration of nitrogen lost in the process is,  

Nitrogen ingested-nitrogen absorbed = 100-80 = 20 grams in a day.  

Let us assume that all the ingested nitrogen is liberated from the muscle. Therefore, 80 grams of nitrogen is liberated. If 90 percent of the nitrogen liberated from the muscle get excreted, then the value of excreted nitrogen will be,  

90% of 80 grams = 90/100*80 = 72 grams

Now the nitrogen recycled will be,  

Liberated nitrogen - excreted nitrogen = 80-72 = 8 grams

From the absorbed food, the fraction of the nitrogen entering the muscle will be,  

80/(80+8) = 80/88 = 0.909.

The correct answer is option B.

Explanation:

If am individual cross between two true breed mice the probability of offspring with heterozygous condition  is 100 percent in such cross. True breed is an individual organism with homozygous for the particular character either dominant or recessive.

So, if mice with RR (purebred or homozygous dominant) bred with mice with  rr (homozygous recessive), all the offspring will be heterozygous in genotype which is Rr.

Thus, the correct answer is : option B. (Punnet square is attached)

Answer:

B

Explanation:

Pigment of chicken feathers is regulated by two genes, the gene for feather pigment C, and a gene that inhibits pigment production, I. A mother chicken, who is heterozygous for gene C, and heterozygous for gene I, is crossed with a father chicken, who is homozygous recessive for the pigment gene, and heterozygous for gene.
1) What are the potential haplotypes of the gametes produced by the mother for these two genes?
2) What are the potential haplotypes of the gametes produced by the father for these two gametes?
3) What is the probability of one of the offspring of these two chickens having pigmented feathers?
4) In a population of 100 chickens, produced from the same parents, how many chickens would you expect to have white feathers?

Answers

Answer:

(1) CI Ci cI ci

(2) CI Ci

(3) 25

(4) 75

Explanation:

Mother is in this case is heterozygous for C & I, genotype of mother would be : CcIi

Father is on other hand is homozygous for C (dominant) and heterozygous for I, genotype : CCIi

1. Gametes produced by the mother will be:

 CI Ci cI ci  by the combinantion of C, I, c, and i alelles present in mothers genotype.

2. Gametes produced by the father :

CI Ci  by the combinantion of alleles present i genotype of father CCIi

3. probability of one of the offspring of these two chickens having pigmented feathers:

 2/8 × 100 = 25% ( punnet is attached)

4. chicken with white feather in population of 100 chickens:

 probability of being white ×  100

probability of being white : 1 - 2/8

thus, (1-2/8) × 100 = 6/8 × 100

Answer:

OA

Explanation:

Chemical energy refers to the energy that is released with reactions involving chemicals. Cellular respiration takes glucose(a five carbon sugar) and breaks it down using glycolysis, then makes ATP(adenisine-triphosphate)(an essential chemical to the energy of life) using the krebs cycle and the electron transport train. This is all to get a surplus ATP, which is a useable CHEMICAL ENERGY source. This energy can be diverted to any system in the body, including the muscular system. Then, the muscles are used MECHANICALLY(look at the types of muscle levers in anatomy) to acheive work, thanks to the CHEMICAL ENERGY produced in cellular respiration. Thus, the answer in OA.

Which statement best explains why fermentation occurs in mammals? It enables mammals to generate additional ATPATP in an oxygen‑rich environment. It breaks down lactic acid to generate a small amount of ATPATP under anaerobic conditions. It generates ethanol, which can be used as an alternative source of energy. It produces an acid that maintains blood pH within a narrow range. It allows glycolysis to continue under anaerobic conditions by replenishing NAD+NAD+ .

Answers

Answer:

The last option.

Explanation:

Fermentation/ Anaerobic respiration is important to supply ATP in the absence of oxygen.

In the presence of oxygen, glycolysis, Kreb's cycle and oxidative phosphorylation happen to provide about 32 ATP molecules. In its absence, only glycolysis can take place because it's the only step that doesnt need oxygen, to give a net supply of 2 ATP.

Even though glycolysis doesn't need oxygen, it needs NAD, and if the reduced NAD doesn't lose its hydrogens via oxidative phosphorylation, pyruvate (the end product of glycolysis) becomes the recipient of the hydrogen.

Pyruvate gets reduced to lactate.

The correct answer as to which best explains why fermentation occurs in mammals would be that it breaks down lactic acid to generate a small amount of ATP under anaerobic condition.

Aerobic respiration takes place in 3 steps:

Glycolysis: during which glucose is converted into pyruvate molecules with 2 ATP and 2NADH molecules produced.Citric acid cycle: during which pyruvate molecules from glycolysis  are converted to CO2 with ATP, NADH, and FADH2 generatedElectron transport chain: during which the NADH and FADH2 produced in citric acid cycle are used to generate ATP.

When oxygen becomes inadequate during rigorous activities in human cells, pyruvate molecules cannot proceed to the citric acid cycle due to lack of oxygen. Instead, the pyruvate molecules are converted to lactic acid through fermentation to generate 2 molecules of ATP.

a. 5 Genes:
b. 10 Genes:
c. 20 Genes:

Answers

Answer:

Explanation:

If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have

2 possible gametes for each five = 2 to the power of 5 = 32 gametes

Then genotypes = 3 to the power of 5 = 243

The same also for 10 genes

2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

Then genotypes = 3 to the power of 10 = 59,049

The same also for 20 genes

2 possible gametes for each 20 = 2 to the power of 20= 1,048,576

Them genotypes = 3 to the power of 20 = 3,486,784,401

Many traits (phenotypes), like eye color, are controlled by multiple genes. In the following scenario, the number of genes are:

a. 5 Genes: 243 genes

b. 10 Genes: 59,049 genes

c. 20 Genes: 3,486,784,401 genes

What are genes?

Genes are small hereditary materials bound in tiny beads like fashion and make a chromosome.

Now, the number of genes in the given scenario is:

a. 5 Genes: If there are 5 genes, let us assume that they are in the alternative forms, with 2 possible gets for each five.

So, 2 possible gametes for each five = 2 to the power of 5 = 32 gametes

The genotypes combinations = 3 to the power of 5 = 243

b. 10 Genes: 2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

The genotypes combinations = 3 to the power of 10 = 59,049

c. 20 Genes: 2 possible gametes for each 20 = 2 to the power of 20 = 1,048,576

The genotypes combinations = 3 to the power of 20 = 3,486,784,401

Therefore, the number of genes is:

a. 5 Genes: 243 genes

b. 10 Genes: 59,049 genes

c. 20 Genes: 3,486,784,401 genes

Predict which one of the following organisms will have the highest percentage of unsaturated fatty acid chains in their membranes: Group of answer choices thermophilic bacteria desert iguana humans antarctic fish

Answers

Answer:

Humans

Explanation:

Humans are bigger than most beings and some people are extremely obese.

The organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.

Unsaturated fatty acid chains have one or more double bonds, while saturated fatty acid chains do not contain any double bonds.

When the temperature decreases, the composition of the phospholipids bilayer membrane becomes more unsaturated to be able to maintain different properties such as homeoviscosity.

In consequence, membrane lipids exhibit the highest percentage of unsaturated fatty acid chains during cold acclimation.

In conclusion, the organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.

Explanation:

Butter, as good as it is, is not exactly good for us. Butter is an animal fat, or a saturated fat. This means that at room temperature these fats will remain solid. There is some science behind it and ill say this quickly, it has to do with the carbon atoms being packed with hydrogen atoms. This allows them to intertwine and be solid. The Vegetable Oil being unsaturated, a plant fat, is good for us! These are missing some of the atoms needed to make them stand up straight and be solid. So these are always liquid at room temperature! :)
