A decomposer it breaks down food that is decaying to only leave the bone of nothing any decaying living object is getting decomposed by mold.
The answer is <span>A. Meiosis: It increases genetic variation, which helps ensure the species will survive.
Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If </span><span>there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. </span><span>If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.</span>
<span>A soil horizon is a layer parallel to the soil surface</span><span>, whose physical characteristics differ from the layers above and beneath</span>
The Answer to this question is b
<span>The answer is
transcription. It is mediated by RNA polymerase enzyme
that reads the DNA template and makes an RNA
strand that is antiparallel and composed of nucleotides complementary to the DNA strand. This process is the first step of
gene expression. </span>
