You are examining the DNA sequences that code for the enzyme phosphofructokinase in skinks and Komodo dragons. You notice that t

he coding sequence that actually directs the sequence of amino acids in the enzyme is very similar in the two organisms but that the surrounding sequences vary quite a bit. What is the most likely explanation for this?
A. Coding sequences are repaired more efficiently.
B. Coding sequences are replicated more efficiently.
C. Coding sequences are packaged more tightly in th e chromosomes to protect them from DNA damage.
D. Mutations in coding sequences are more likely to e deleterious to the organism than mutations in noncoding sequences.
E. Recombination between skink and Komodo dragon DNA occurred recently

Answer:

The correct answer is D.

Explanation:

Mutations in coding sequences are more likely to be deleterious to the organism than mutations in non-coding sequences.

Mutations in coding sequence is more harmful because they end up mutating the protein coding region of the DNA , which alters the function of proteins.

These mutations may cause some harmful genetic disorder or end up causing cancer.  That is why mutations  in coding sequences are more harmful to the organism than mutations in non-coding sequences.

aerobic respiration results in the production of large amounts of lactic acid. How does this impact the body? What is one real l
neonofarm [45]
It’s actually called anaerobic cellular respiration because you’re not using oxygen. For example, when you sprint you can’t breathe very well, so you’re not inhaling as much oxygen you need to make that energy for you to move. Your muscles will go into lactic acid fermentation, and the result of that is energy (ATP) along with lactate (lactic acid), and you will probably start feeling pain as the lactic acids build up.

Hope that helps!

Which best represents the role of the cell cycle in repair of an organism? an active cell cycle from a puncture wound an active
anygoal [31]

Answer:

The cell cycle best repairs organism from a puncture wound.

Explanation:

Repairing in organism means restoration of damaged tissue and its functioning. In a cell cycle, a tissue is repaired through the process of Mitiosis in cell division. It helps in growth of cell.

Through this process identical cell copies are produced by which the punctured wound or damaged tissue is replaced.  Thus, cell cycle is seen in playing an important role in repairing an organism.

Drag the terms on the left to the appropriate blanks on the right to complete the sentences. resethelp biomass assimilated feces
yaroslaw [1]

1. The right answer is not assimilated

The assimilation designates in biology the process by which substances and materials external to the body are transformed into substances and materials interior to the body.

2.  The right answer is feces.

Feces correspond to the residue of digestion that the intestine could not absorb. They consist of 80% water and 20% dry matter (intestinal cell debris, bacteria, cellulose that comes from the non-absorbable part of plants).

3. The right answer is assimilated  

The opposite of the first one.

4. The right answer is cellular respiration.

Cellular respiration is the process of cellular metabolism that converts the chemical energy contained in nutrients into ATP (adenosine triphosphate).

5. The right answer is assimilated

"Assimilation" can be also used for energy.

6. The right answer is biomass

In the field of energy, biomass is the organic matter of plant origin (microalgae included), animal, bacterial or fungal (fungi), usable as a source of energy.

7. The right answer is biosynthesis.

Biosynthesis consists of a formation and production of a chemical compound body by a living organism, usually due to the catalysis of an enzyme. For example, protein synthesis is the synthesis of organic substances by an organism. Chemosynthesis and photosynthesis are biosynthesis.

8. The right answer is non assimilated.

Since it is lost, so it is not assimilated by the organism.

9. The right answer is biosynthesis.

In ecology, the trophic level is the rank occupied by a living being in a food web. It is measured in some way by the distance separating this being from the basic level which is that of the primary autotrophic production.

Above this basic level, each link (or stage) of a food chain corresponds to a trophic level.
