sveta [45]

Answer:

(C) each cell of an organism has all the genes needed for development.

Explanation:

According to my research on studies conducted on Genetics, I can say that based on the information provided within the question this illustrates that each cell of an organism has all the genes needed for development. If this were not the case then the frog would either not be born or would be born with serious abnormalities because the cell did not have the necessary genes needed for the frog to form correctly.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

In flowering plants, plasmodesmata are narrow channels through cell walls that connect the cytoplasms of adjacent cells. An expl
Naddika [18.5K]

Answer:

Option-D

Explanation:

Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.

The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.

The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.

Thus, Option-D is the correct answer.

How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in G 1 of the cell cy
Vikentia [17]

Answer:

b. The daughter cells have the same number of chromosomes and the same amount of DNA.

Explanation:

Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.

For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
