A woman is 32 years old, after fiscussion it was noticed that she got her puberty at the age of 16 and has one children. How much polar bodies were formed at the age of 32?
Answer:
134
Explanation:
Polar bodies are formed each month after attaining puberty. Hence, total years of polar bodies formation are equal to the difference between the age of puberty till date.
Hence, total years of polar bodies formed = 32-16= 16
Hence, total number of polar bodies formed 16×12= 192
For one child absence of polar bodies formation = 15 months, where 9 months of gestation and 6 months of lactation.
So, for 1 child, it will be 15 x 1 = 15
Hence, net polar bodies formed in her body till date - 120 + 1 - 15 = 134
Hence, net polar bodies formed in her body till date 134

Explanation:
nonliving characteristics include the fact that they are not cells have no cytoplasm or cellular organelles and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. And viruses can infect animals, plants and even other microorganisms.
The man is not color blind, but his wife is. They already have one daughter that is color blind and want to know the probability of future children having the disorder. First, you will need to explain to the couple the difference between sex chromosomes and autosomal chromosomes and that color blindness is caused by a recessive mutation in a gene found on the X chromosome. Once they understand this, you can then explain to them the probability of other offspring having the disorder. What is the dilemma in this case and why might you need to suggest to the couple that they see a marriage counselor?
Answer:
It’s not likely to have a color blind daughter from a normal father and with a color blind mother. In order to obtain this disease in females, both parents have to pass one color blind allele or gene along with an X chromosome, but the father in this scenario is not colorblind, so the color blind daughter probably is not a child of theirs.

B.) A spore divides and grows into a pollen grain using mitosis.
C.) Young male cones produce spores using meiosis.
D.) A seed develops after the sperm from a pollen grain fertilizes the egg in an ovule.
Answer:
A
Explanation:
i took this quiz and I am pretty sure it is A
please dont be mad if it wrong
Stage 5 could represent "Young female cones produce spores from cells that divide using meiosis" (option A).
What is the life cycle of a pine tree?The life cycle of a pine tree begins with the production of male and female cones on the tree. Male cones produce pollen grains, which contain the male gametes or sperm cells, while female cones produce ovules, which contain the female gametes or egg cells. Pollen grains are carried by the wind and land on the female cones, where they fertilize the egg cells.
The fertilized egg cells then develop into seeds, which are protected by the woody scales of the cone. The cones mature and open, releasing the seeds, which can be dispersed by the wind, animals or gravity. The seeds then germinate and grow into seedlings, which develop into juvenile trees.
As the tree grows, it produces more cones, and the cycle repeats itself, ensuring the continued propagation of the species. This cycle can take several years to complete, depending on the species of pine tree.

Describe the energy-releasing reaction shown in figure 1
idkeubeekenebekeenne
The energy-releasing reaction shown is the reaction of phosphorylation of fructose-6-phosphate to fructose-1, 6-bisphosphate.
Phosphorylation simply means the biochemical process that has to do with the addition of phosphate to an organic compound.
In this case, there's a reaction with fructose-6-phosphate to fructose-1, 6-bisphosphate.
Also, the ATP molecules have three high-energy phosphate groups which are vital for the transfer of one of its phosphate groups to fructose-6-phosphate and also provide energy to carry out the reaction.

Which of the following describes how regions of phospholipids are arranged in the cell membrane?
Answer:
phospholipds are arranged in the phospholipid bilayer, inside the plasma membrane.
Explanation:
they have one hydrophilic head and two hydrophobic tails.
Phospholipids are amphipathic molecules that compose the cell bilayer membrane. Among the options, D is correct. Hydrophobic fatty acid regions face each other within the interior of the cell membrane.
-----------------------------------------------------
Two lipidic layers compose the cell membrane. There are also proteins and glucans incrusted in between.
The complex lipids that compose the membrane are amphipathic molecules. A phospholipid is composed of
two fatty acid chains ⇒ hydrophobic tails, glycerol and a phosphate group ⇒ hydrophilic heads negatively charged
Phospholipids are arranged as a bilayer. Their hydrophilic polar heads face the exterior and the interior of the cells, while their hydrophobic tails are hidden against each other, constituting the internal part of the membrane.
According to this framework, we can choose the best answer among the options,
A) Hydrophilic phosphate regions face each other within the interior of the cell membrane ⇒ Incorrect ⇒ Heads are not facing each other. They are in contact with the cell exterior and interior.
B) Hydrophilic phosphate regions are positioned toward nonpolar environments ⇒ Incorrect ⇒ Phosphate regions are in contact with water.
C) Hydrophobic fatty acid regions are positioned toward polar environments ⇒ Incorrect ⇒ tails can not be in contact with water.
D) Hydrophobic fatty acid regions face each other within the interior of the cell membrane ⇒ CORRECT.

If the newly-founded island population of moths in your GENETIC DRIFT Lab
simulation contains 30 (BB) black, 12 (Bb) grey, & 3 (bb) white moths, what is
the frequency of the white alleleb alleles) for the moth-coloration gene in the
population
10%
139
200
Submit
Request Answer
Answer:
0.2 (or 20%)
Explanation:
The allele frequency can be calculated by counting how many times an allele appears in a population and then by dividing this number by the total number of alleles of the gene. In this case,
- Genotype BB = 30 moths >> 60 copies of the B allele
- Genotype Bb= 12 grey moths >> 12 copies of the B allele and 12 copies of the b allele
- Genotype bb= 3 white moths >> 6 copies of the b allele
The total number of copies of the gene is:
Dominant (B) allele = 60 (BB genotype) + 12 (Bb genotype) = 72 B alleles
Recessive (b) allele = 12 (Bb genotype) + 6 (bb genotype) = 18 B alleles
Then, 72 + 18 = 90 alleles
Allele frequencies:
Dominant (B) allele = 72/90 = 0.8 (or 80 %)
Recessive (b) allele = 18/90 = 0.2 (or 20%)
The frequency of the white allele b alleles for the moth-coloration gene in the population - 40%
The frequency of an allele can be calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population
Total number of b alleles = number of alleles present in recessive bb + number of alleles present in heterozygotes Bb
Number of bb individuals = 3 Number of b alleles present in bb = 3 × 2 = 6 Number of Bb individuals = 12 Number of b alleles present in Bb = 12 × 1 = 12 Total number of b alleles = 6 + 12 = 18the frequency of an alele = 18/45
= 40%
Thus, the frequency of the white allele b alleles for the moth-coloration gene in the population - 40%

Mutations can be either spontaneous (no known cause) or induced (caused by specific environmental agents). What are some environmental agents that could increase the rates of genetic mutations among humans today? What types of mutations have the potential to be the most significant from an evolutionary perspective?
Answer:
Explanation:
Mutations happen spontaneously. The rate of mutation can be increased by environmental factors such as UV radiation , X-rays, gamma rays and certain types of chemicals such as bromine. These are some factor that can increase the rate of mutation
The classic example of evolutionary change in humans is the hemoglobin mutation named HbS that makes red blood cells take on a curved, sickle-like shape. With one copy, it confers resistance to malaria, but with two copies, it causes the illness of sickle-cell anemia. Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision.
Explanation:
Look the Mutations happen spontaneosly.So this means that this can increased by the enviromental factors such as Uv radiation, The X-rays, The Gamma Rays, and for last one the certain types of chemicals such as a bromine.These are some factors that increase the rate of the mutation.

in what stage of mitosis is this cell going through?
Answer:
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations.
It has four stages,
1- Prophase: The chromosomes are condensed into the X-shaped structures that can be easily seen under a microscope.
2- Metaphase: The chromosomes come end-to-end at the center (equator) of the cell.
3- Anaphase: In this Phase, The sister chromatids are pulled apart by the mitotic spindle to the opposite poles. One spindle fiber pull a chromosome to one pole and other spindle fiber to the other pole.
4- Telophase: At each pole of the cell a full set of chromosomes gather together.

Though the microbes described in the introductory chapter do not corrode the metal in the subway, many microbes influence corrosion and deterioration of metal and stone. Other microbes have other effects on their environment. During wastewater treatment, bacteria are used to reduce the amount of organic and inorganic materials so that the water no longer supports substantial microbial growth. During secondary wastewater treatment, bacteria within sludge digesters break down organic materials into fatty acids, H2, and CO2. These products are fermented to acetate, CO2, and H2. Finally, archaeans ferment acetate to form methane and carbon dioxide. Just by knowing this information, what is true of the bacteria used in sludge digesters?
a. They are capable of anaerobic metabolism.
b. They are sulfate-reducing bacteria.
c. Some are methanogens.
d. They are capable of forming slime layers.
Answer:
a. They are capable of anaerobic metabolism.
c. Some are methanogens.
Explanation:
The bacteria used in order to treat wastewater can be classified as anaerobic, aerobic, and facultative. Anaerobic bacteria are able to treat wastewater in low or null oxygen conditions by the process of methanogenesis. Methanogenesis is a metabolic process that involves the formation of methane (CH4) by anaerobic Archaea known as methanogens. The process of methanogenesis occurs in anaerobic environments, such as during waste sludge treatment, where these microorganisms are able to breakdown organic pollutants. Methanogens produce methane during catabolic pathways that involve the breakdown of complex molecules into simpler molecules.
