Answer:
D.
Explanation:
we learned about this in living environment! for example: humans used to have tails but the humans without tails offspringed with the ones with tails causing the genetics to take over making different traits appear in offspring. Therefor, the answer is D.
Answer: A (catabolism and Anabolism)
Explanation:
Metabolic pathway are basically divided into two categories.
1. Catabolic
2. Anabolic
Catabolic (degradation) pathways, where energy rich complex macramolecules are degraded into smaller molecules. Energy released during this is trapped as chemical energy, usually as ATP.
Anabolic (biosynthesis) pathways. The cells synthesize complex molecules from simple precursors. This needs energy.
The correct answer is Option (B) Habituation.
Crocodiles ignore the birds which clean their teeth instead of eating them. This is an example of habituation.
<h3>Why do crocodiles show habituation toward the birds which clean their teeth?</h3>
It's an evolutionary phenomenon that when a bird used to sit in a crocodile’s mouth, the crocodile didn't eat it, instead, the crocodile used to allow the bird to sit in the mouth and clean the teeth of the crocodile so that they can alive longer, whereas the birds could get the free food from the crocodile’s mouth. It is an example of the symbiotic relationship between the two.
So, the same is the case today, crocodiles are habituated to the fact that the birds will clean their teeth so instead of eating them, these birds are being ignored by the crocodiles.

Answer:
can ,synthesize specific proteins
Explanation:
Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.
They are transported in the circulatory system of the body
The action of hormones can be seen after the hormone has bound to its specific receptor found inside the cell.
For instance, steroid hormone and the thyroid hormones can pass through the plasma membrane to their receptors inside the cells.
When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.
Answer:
We could use up all of them right away and not have the resources for humans and animals to survive.
Explanation:
Right now, we are using our natural resources at a consistent rate. We sometimes use to many of them in one day. If we continue using up our natural resources at the rate we are right now. We may not have the necessary resources to survive in about 10-20 years.
Hope this helps!
