7. The correct answer is photosynthesis.

Autotrophs are organisms which produce food for themselves-from simple to complex molecules. In the case of photosynthesis, producers (plants or some algae) use the light energy to produce complex organic compounds (carbohydrates, fats, and proteins).

8. The correct answer is primary consumers.

Since the pioneer species are usually autotrophs because there is no other source of energy except light energy in the early stages of succession (after the eruption). Most likely, the primary consumer will appear next because they feed upon producers.

9. The correct answer is: they are different populations of fish.

Those two different kinds of fish have unique adaptations that enable them to survive and live in distinct environments. It is most likely that molecular changes underlie adaptation and speciation of those fishes.

svlad2 [7]

Answer:

Explanation:

Gas exchange. Gas exchange occurs as a result of respiration, when carbon dioxide is excreted and oxygen taken up, and photosynthesis, when oxygen is excreted and carbon dioxide is taken up. The rate of gas exchange is affected by: the area available for diffusion.

When sperm and ovum unite at conception, a(n) __________ results. autosome gamete zygote allele?

frosja888 [35]

Answer;

-Zygote

When sperm and ovum unite at conception, a zygote results.

Explanation;

-Conception occurs when a sperm cell from a fertile man swims up through the vagina and into the uterus of a woman and joins with the woman's egg cell (ovum) as it travels down one of the Fallopian tubes from the ovary to the uterus.

-A zygote is the union of the sperm cell and the ovum. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo.

Indicate whether the C-terminus (C) or the N-terminus (N) of each of the following proteins is expected to be located in the cyt

musickatia [10]

Answer:

The correct answer is - CNN.

Explanation:

Protein modification or folding takes place in the endoplasmic reticulum. The Endoplasmic Reticulum modifies the amino acids according to their signal sequences and tail. The following case can help in indicating the C-terminus (C) or the N-terminus (N) of each of the following proteins-

A) the C-terminus would be placed in the cytosol and the N-terminus in the endoplasmic reticulum lumen after cleaving the N-terminal signal sequence.

B) The N -terminal is the positive end of the chain and as per the rule of positive inside it allows N terminal in the cytosol

( C ) Tail-anchored proteins always have their N-terminal bulk in the cytosol.

Thus, CNN would be the correct answer from the explanation given above.
