Trichomes increase the chances of survival for plants living in areas with infrequent rainfall.

If a plant in a very rainy place had trichomes, it would probably adapt and remove them as time passed as they are unnecessary.

How does gene expression lead to differentiation
ExtremeBDS [4]
Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.

What will most likely happen to the population of bison that feed on the grass
Mandarinka [93]
If a portion of the grass was destroyed by wildfire, then the population of bison that feed on the grass will decrease. This is because there would be very little grass left for them to eat, and they don't eat anything else.

Besides producing sugar for itself, a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradien
tino4ka555 [31]

Besides producing sugar for itself a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradients and potassium to make enzymes.

<u>Explanation:</u>

Plant sugar is glucose and plants produce it by the process of photosynthesis making use of energy from sunlight, carbon dioxide absorbed from the atmosphere and the presence of chlorophyll in its parts. Plants also require components other than this. Nitrogen is essential to make proteins and it cannot be directly absorbed from the atmosphere but has to be absorbed from the soil.

Potassium is an essential component which is absorbed from the soil. It facilitates the activation of enzymes which play a crucial role in plant metabolism.  When plants lack potassium they won’t have enough energy for proper growth and will have poorly formed roots and weak stems.
