Answer:

I think its D.

Explanation:

Pollination allows plants to improve genetic diversity within their species and, in some cases, plants will cross-pollinate with other flower varieties. This creates a heartier, more genetically diverse plant population and sometimes drives a mutation that results in a new species or hybrid.

Suppose that an arginine residue in the active site of an enzyme was mutated to alanine. As expected, the alanine mutant was ina
Makovka662 [10]

Answer:

Alanine to lysine.

Explanation:

Mutation may be defined as the sudden, heritable change in the genome sequence of an organism. Two main types of mutation are chromosomal mutation and point mutation.

The mutation has occurred in which the arginine is replaced by alanine. The mutation that can restore to wild type is the conversion of alanine with lysine.    Since both arginine and lysine are basic amino acids. They both shows almost similar function and the replacement of lysine with alanine shows the wild type activity.

Thus, the answer is alanine to lysine.

What are the similarities and differences between the low-light seedlings and the moderate-light seedlings?
Natalka [10]

The similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.

<h3>What is photosynthesis rate?</h3>

The photosynthesis rate is the amount of photosynthetic products (i.e., glucose) that generates by a plant in a given unit of time, which depends on the amount of chlorophyll.

In this case,  low-light seedlings and moderate-light seedlings produce amount of chlorophyll at a similar rate until 12 hours, while the maximized value for moderate-light seedlings and low-light seedlings is 48 hours.

In conclusion, the similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.

Which tissues are characterized as being highly cellular but avascular? nervous and muscle muscle only epithelial and connective
den301095 [7]
I think the answer is <span>epithelial and connective tissue

Muscle cells need much energy to moves its fiber, so it must be on a highly vascularized area. The nervous system also needs a blood supply to works. In fact, the brain cells use the highest amount of energy.
Epithelial and connective tissue doesn't need much energy because its main function is to protect other tissue. It also has densely packed cells to make it sturdy.</span>

ioda
The Earth turns on its axis every day; it orbits the sun, just like all the other planets in our Solar System. You can cross out D and A, obviously. Which leaves us with answers B and C. Now, C says that the Earth turns clockwise, which is false; when viewed from space, they determined it turned counter-clockwise, which leaves us with B. Hope this helped
