Answer:
At the end of DNA replication, each copy is identical to each other (option A).
Explanation:
The concept of DNA replication implies that, from an original molecule, two identical molecules are obtained.
DNA replication is based on a semi-conservative model, since the double strand is separated, and each strand serves as a mold for the synthesis of a new strand. <u>At the end of the replication, two identical DNA molecules will be obtained, each consisting of an original strand and a new one</u>.
The best evidence that the replication process results in two identical molecules is that, otherwise, an individual's genetic information could vary, which does not happen.
The other options are not correct because:
<em> B. The copies cannot be different.
</em>
<em> C and D. They are 100% identical, not partially (50 or 90%) similar.</em>

Explanation:
I'm not really sure what this question is about - is it a true or false question? If so, then the answer is true - given that there are fewer bamboo plants in the world (because they cannot grow as fast as pandas can eat them), there won't be enough food for pandas to thrive, and thus they won't survive for much longer.
If you just need to write the words necessary to complete the sentence, then 'on which,' 'is now scarce,' 'about,' and 'their' are the correct answers.
Answer:
Negative feedback.
Explanation:
It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.
In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.
