Answer/Explanation:
We are not told if the plant has 20 chromosomes in total or 20 pairs of chromosomes. E.g. a human has 23 chromosomes, but we are diploid, so there are 46 chromosomes present in most cells.
An exception to the rule is the gametes, or the sex cells, where we are haploid. We have 23 chromosomes in these cells.
Pollen cells in plants are the sex cells. Therefore, they are haploid. If we assume that 20 chromosomes is the haploid number (and there are therefore 20 pairs of chromosomes) then the pollen will have 20 chromosomes.
If we assume that 20 chromosomes is the diploid number (and therefore there are 10 pairs of chromosomes), then the pollen will have 10 chromosomes.
Answer:
Symbiosis or Mutualism: When two species live together in a close association that is helpful to both species, the relationship is known as symbiosis. The oxpecker bird and the rhinoceros exhibit this relationship. The oxpecker receives protection and obtains food from the ticks and other pests infesting the rhino’s skin.

The answer would be: T<span>hese drugs are similar but some clients respond better to one than the other.
Elavil and anafranil come from similar drug family of amitriptyline type. But they have a different structure which will have some effect on the pharmacokinetic and pharmacodynamic of the drug.
This could lead to different response and results in the different patient. The drug is similar, but the effect might be different.</span>
