PLEASE HURRY A mutation occurs when a base in the DNA sequence is replaced by a different base.

Answers

Answer 1

Answer:       Mutations

Explanation:

A substitution mutation occurs when specific bases (A, T, C or G) in a gene are swapped for different ones. This type of mutation doesn't cause a difference in the number of bases like insertion or deletion mutations do. Substitution mutations just switch out one or more bases for different ones.

List 7 organelles shared by both plant and animal cells.

Answers

Answer:

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Explanation:

The 7 organelles shared by both plant and animal cells are the nucleus,  endoplasmic reticulum, mitochondria, peroxisomes, Golgi apparatus, lysosomes, and cytosol.

A cell is the most basic structural and fundamental unit of life.

Plant cells are eukaryotic cells with membrane-bound organelles that composed the basic unit of the plant. The major difference between the plant cell and an animal cell is that the plant cell has a cell wall.

An animal cell is present in animals and they are also eukaryotic in nature. Animal cells are enveloped by a plasma membrane and they do not have a cell wall.

The organelles that are shared by both plant and animal cells are:

nucleus,mitochondria, endoplasmic reticulum, Golgi apparatus,lysosomes,peroxisomescytosol

Therefore, we can conclude that the plant cell and the animal cell shared some similar organelles together.

In a rainforest food chain, caterpillars and butterflies eat orchid plants. Toucans eat the caterpillars and butterflies. Leopards eat the toucans.


Which statement describes the energy in this food chain?


The leopards gain energy directly from the butterflies.

The orchids have the least amount of available energy.

The caterpillars gain energy directly from the orchids.

The toucans have more available energy than the butterflies.

Genetics is the most important factor that affects your physical fitness.

Answers

Answer:

The caterpillars gain energy directly from the orchids.

Explanation:

The correct answer would be that the caterpillars gain energy directly from the orchids.

Since the caterpillars feed on the orchid plant, they gain their energy directly from it. The orchid plant represents the primary producer in the food chain while both the caterpillars and the butterflies are primary consumers.

The leopard does not gain its energy directly from the butterflies because the animal does not feed directly on the butterflies. The orchid has the highest amount of energy available because it gets its energy from the sun through photosynthesis. The toucans cannot have more energy available than the butterflies because the more you move up the food chain, the lesser the energy available.

three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle

Answers

Answer:  

-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)

-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)

-termite’s feces help to prevent erosion  

Explanation:

Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.

What is a possible explanation for this observation? EVOLUTION CONNECTION sequences can act as "tape measures of evolution". Scientists analyzing the human genome sequence were surprised to find that some of the regions of the human genome that are most highly conserved (similar to comparable regions in other species) don't code for proteins. What is a possible explanation for this observation?

Answers

Answer:

Non-coding DNA regions play important roles in regulating transcriptional activity by encoding different types of non-coding RNAs (ncRNAs), acting as scaffold attachment regions, acting as enhancer specific regions, etc.

Explanation:

Historically, it had been believed that non-coding DNA sequences were 'junk DNA' since they don't encode for proteins (beyond the sequences that are transcribed into functional non-coding RNAs, i.e., transfer RNA and ribosomal RNA). However, in the last years, it has been shown that non-coding DNA sequences play critical roles in regulating gene expression and genome function. For example, evolutionary conserved non-coding RNAs (ncRNAs) with regulatory roles on gene expression such as, for example, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been mapped in non-coding DNA sequences, thereby evidencing the functional significance of these regions. In consequence, the conservative nature of certain non-coding DNA sequences evidence that mutations in such regions may have significant deleterious effects, and thereby they could have a negative impact on the fitness of the individual.

Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below.Her friend Byron evaluates the model, and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them. A. The model shows that their combined effects determine the amount of solid carbon compounds in the geosphere.
B. The model shows that their combined effects determine the level of carbon dioxide that dissolves in the hydrosphere.
C. The model shows that they have identical effects on carbon dioxide levels in the atmosphere.
D. The model shows that they have opposite effects on carbon dioxide levels in the atmosphere.

Answers

The missing part of this incomplete question is :

How does Francine's model show the effect of photosynthesis and cellular respiration on Earth systems?

Answer:

The correct answer is - option D. The model shows that they have opposite effects on carbon dioxide levels in the atmosphere.

Explanation:

Cellular respiration and photosynthesis are two major processes are involved in the carbon cycle and both have the opposite effect on carbon dioxide levels in the atmosphere.

Photosynthesis uses carbon dioxide from the atmosphere to produce glucose with the reaction with the water whereas cellular respiration produces energy and carbon dioxide that is restored in the atmosphere.

Thus, both the processes have the opposite effect on the carbon dioxide levels in the atmosphere as photosynthesis decreases and cellular respiration increases in the atmosphere.

Which of the following is true regarding the machinery of translation?

a. A single mRNA can be translated simultaneously by several ribosomes.
b. tRNAs released from the ribosome are degraded B) termination and eukaryotes utilizes three different release factors.
c. Polycistronic MRNA usually has a single ribosome binding site.
e. once a single mRNA strand is translated once it is degraded

Answers

Answer:

The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.

Explanation:

Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.

To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a polysome and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.

The true statement regarding the machinery of translation is ; ( A ) A single mRNA can be translated simultaneously by several ribosomes

Translation is the process of producing protein with the use of RNA ( i.e. the process of protein synthesis from  an mRNA template )  during translation the code found in the template is converted into an amino acid sequence.

Ribosomes are composed of rRNA which directs the process of translation with the proteins and key molecules such as tRNA.

Hence we can conclude that the true statement regarding the machinery of translation is A single mRNA can be translated simultaneously by several ribosomes.

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is dominant to dull (g) and Long (L) hair is dominant to short (l). You have a pair of dogs that you have been breeding for several years. The mom is glossy long haired and the dad is dull short haired. Over several litters they have produced the following puppies: 18 Glossy Short 16 Dull Long 8 Dull Short 6 Glossy Long What are the parental gametes produced by this mom

Answers

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL   x   ggll

Progeny = all GgLl (all glossy long haired)

GgLL   x   ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl    x    ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl    x    ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.
