Answer:
protista, bacteria. archaea, fungi.
Explanation:
The correct answer is: Induction, because this could be easily changed by changing the cell's environment.
Cell differentiation (process by which cell becomes specialized) can be under the influence of many factors:
• Cytoplasmic influence because cytoplasm can influence and control the behaviour of nuclear genes.
• Embryonic induction-changing the cell environment
For example: if cells from one region of the embryo are transplanted to some other region that transplant will most likely differentiate according to the chemical regulators of the surrounding cells.
• Proteins present in a cell influences its differentiation
• Cell-Cell interactions via cell-cell adhesion and signalling molecules.
<span>In a balanced ecosystem, the number of secondary consumers must be fewer than the number of primary consumers.
In a balanced ecosystem, the number of producers is ALWAYS the largest. As the trophic levels increase, the number of organism decrease, so primary consumers are less than producers, secondary consumers are less than primary consumers, and so on.</span>
I think it's called the Acrosome
Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
