Answer:
The main reason is attributed to habitat loss, as animals are left without places to live as areas around the planet are being taken over and changed by human presence. With the added pressures of invasive species and climate change, the study writes, species are vanishing faster.
Explanation:
Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. ... During cell differentiation, the cell size and shape changes dramatically, as does its ability to respond to signaling molecules.
The correct option is C
<span>C.Stomata would not open and close.
</span>
This is because guard cells play an important function of controlling stomata. the ensures that stomata are open during the day and closed during the night for the purposes of photosynthesis.

A drug that interacts directly with receptor sites to cause the same activity that a natural chemical would cause at that site is the instructors best response.
Explanation:
Receptors are Macromolecules which involved in chemical signalling within cells. It is possible that receptors are located in the cell surface membrane. Cellular biochemical process is regulated by Activated receptor. The drugs are capable to affect to receptor who is related to the drug’s affinity and also intrinsic efficacy.
The affinity and activity of drug is related to its chemical structure. its effect is decided by the time duration where complex persistence of drug-receptor.
