Afrog has a genetic mutation in its skin cells that causes part of its skin to turn orange. the frog will not pass this genetic mutation onto its offspring because
parents do not contribute genetic material to their offspring.

skin cells do not contribute genetic material to sex cells.

mutated skin cells cannot divide and produce daughter skin cells.

the offspring will inherit skin cells from the other parent.

Answer : The correct answer is -

skin cells do not contribute genetic material to sex cells.

Sex cells are the haploid, reproductive cells (also known as gametes, such as sperms and egg) that are produced by parents through gametogenesis (oogenesis in female and spermatogenesis in male).

They are crucial for reproduction in sexually reproducing organisms (like humans) as they fuse together and form a diploid zygote (containing the genetic material of each parent) which develops into fetus.

On the other hand, skin cells are the somatic cells (that are diploid) and do not contribute in the reproductive cycle.

This means that their genetic material is not contributed to the sex cells.

Thus, the frog with genetic mutation in its skin cells will not pass it to the offspring.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
