Answer:
Explanation:
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
I think it is phytoplankton:)
The answer is false
When the cells are differentiating in the embryo, they retain the same genetic material. However, certain genes in the differentiating cells are silenced using protein complexes called histones. This makes the genes inaccessible to RNA. Therefore, the process of transcription required in the expression of genes is restricted.
The gametes are formed by cellular reproduction process of meiosis.
Meiosis is the cell division that splits the chromosomes into half the number resulting in four haploid cells. The daughter cells are completely different from the parent cell.
Hence the option Meiosis is the right answer
