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.
Biodiversity is rapidly declining across the globe.
Explanation:
The biodiversity across the globe has been under heavy blow, especially in the past few hundred years. The main reason for this are the humans. The humans with their activities have managed to destroy the habitats in lot of places, which in turn resulted in sharp decline in biodiversity. Also, some species have been systemically killed off, some because they have been considered as pests, some because they were used as a food source.
- Naturally, the biodiversity tends to be at a sustainable level, while some species die out, other replace them.
- In the more recent history though, there is a mass extinction occurring because of the humans activities, not because of natural causes.
- With the growing human population the trend of destroying the environment continues and it will continue further in the future, with the biodiversity constantly going down and lot of species ending up being endangered or extinct.

Answer:
Diploid cells abbreviated 2n and haploid cells abbreviated 1n because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.
Diploid cells are present in body cells while haploid cells are found in sex cells.
