What is the job of the enzyme telomerase?

Answers

Answer:

Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells. In human somatic cells proliferation potential is strictly limited and senescence follows approximately 50-70 cell divisions.

When an organism such as a yeast lives by fermentation, it converts the pyruvate from glycolysis into a different compound, such as alcohol. Why doesn't it secrete the pyruvate directly? Group of answer choices The conversion yields one NADH per pyruvate molecule. A buildup of pyruvate in the surrounding environment would be too toxic. The conversion is needed to regenerate the molecules needed for glycolysis. The conversion yields 32 ATP per pyruvate molecule.

Answers

Answer:

The conversion is needed to regenerate the molecules needed for glycolysis

Explanation:

Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.

plz help!!! Gall flies lay their eggs in developing shoots of the tall goldenrod. When the fly larvae hatch, they release chemicals that cause the plant tissue to swell around the larvae, causing a resultant gall to form. The gall flies are prey for the parasitic wasp that lays its eggs in the smallest galls. After the wasp larvae hatch, they eat the fly larvae. The gall fly is also prey for the downy woodpeckers that feed on the larvae of the largest galls. Which type of natural selection may the gall fly be subject to?

Explain your justification for the changes in trait distribution between years 1 and 10. What do you think will happen to the population by year 15?

Answers

Answer:

It will continue to rise.

Explanation:

Genetic variation results in the changes in trait over the period of time. Hence, traits do change over the years, but it is a gradual process. The population will become more stable due to successful traits.

What is genetic variation?

Genetic variation refers to the changes in the genotype of an individual. It imparts stability to the population. Genetic variation results from meiotic cell division where recombination of gene produces genetic exchange of heredity material.

Those traits which are successful in nature that means those variations which provide stability to the organism in any environment are favoured. Organisms with such variations adapt, survive and further reproduce to continue their existence. Such traits are transmitted to the progeny as well.

Thus, gradual accumulation of changes in traits contribute to a more stable population over the span of years.

Therefore, changes in traits are important in determining the track of evolution on earth.

Meiosis Which of the following best describes the image to the right? OB 0 0 0 0 A. Meiosis 2 B. Mitosis h C. Binary fission D. Meiosis 1​

Answers

The answer to your question is B.

Cell division is a process by which the cell divides into two or four daughter cells. The image shows meiosis II, cell division. Thus, option A is correct.

What is meiosis II?

Meiosis II is a stage of meiotic cell division that only occurs in the body's germinal cells and results in the production of four daughter cells with a ploidy count of the half.

It is comparable to mitotic division, in which cells go through the prophase, anaphase, metaphase, and telophase stages. But they differ in the production of the four haploid daughter cells.

The meiotic division II is characterized by the separation of the sister chromatids resulting in decreases in the chromosomal numbers and the ploidy of the cell.

Therefore, the image shows the meiotic II cell division. Option A is correct.

What strand is "read" in order to get the amino acid sequence?

Answers

The mRNA is “read” according to the genetic code. This is a step in translation, the mRNA relates to the DNA sequence to the amino acid sequence in proteins

Answer:

In translation, the cell uses an mRNA strand that it has just transcribed from its genetic code as a template to assemble proteins. The cell has just transcribed this mRNA stand from its DNA, and now it translates the mRNA's nucleotide sequence into a chain of amino acids.
