Answer:
2 TT, 2 Tt.
Explanation:
The phenotype would be 4 yellow because T is dominant.
Answer:
The correct option is <u>less</u>.
Explanation:
outside an organism's body.
A hypotonic environment can be described as an environment in which the amount of solvent is more outside the cell as compared to the inside of the cell. The amount of solutes is more inside the cell. Hence, water tends to move inwards by osmosis in such an environment.
An isotonic environment can be described as an environment where the concentration of solutes and solvents is the same inside and outside of a cell.
When paramecium caudatum would be in a hypotonic environment, its contractile vacuole will be more active to pump the excess water. In an isotonic environment, there will be no or very less water for the paramecium to pump out of the body. Hence, contractile vacuole will be less active.
The process by which cell types or cell populations attain distinct and different forms and functions is called differentiation.
This is the process that allows the stem cells to differentiate and form a cell type that will perform a specific function.
The process of differentiation is essential for the formation of the different organs in multicellular organisms.
If it were to have experimental observation as part of the process, your answer would be B. If not supported by an experimental observation it would remain as just a hypothesis.
