Because genes must be able to adapt to either the internal or exterior environment, they are regulated. Since DNA duplication begins with transcription, there are benefits to controlling transcription precisely.

The process of activating and deactivating genes is referred to as gene regulation. During development, genes are turned on and off in various patterns to give a brain cell a different appearance and behaviour from a liver cell or a muscle cell. There are two types of control . Limiting the amount of mRNA that can be created from a single gene is one way to control transcription. Another way is through post-transcriptional processes that affect how mRNA is translated into proteins.

Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentca
postnew [5]

Answer:

can lead to natural selection

Explanation:

<h2></h2><h2>Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>

This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>

So overtime, the organism which is weaker  (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in  a way "<u>Nature selected"</u><u> </u>the better fit organism.

How does a whale-fall community affect ocean sediment?
Leokris [45]

The decomposition of the whale enriches the sediment.


<span>When a whale dies, it falls to the ocean floor. Its dead body is known as whale-fall. This whale-fall provides nutrients for a whale-fall community, which includes bacteria, crabs, worms and other invertebrates. Organic fragments from the whale-fall enrich the sediments nearby. Enrichment opportunists colonize the whalebone and surrounding sediment in order to feed on these organic fragments.</span>
