Which structure is perforated with pores to allow material to move in and out of the nucleus?.
erastovalidia [21]

The nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

Every cell in the body has a nucleus, except for mature erythrocytes (red blood cells). While some cells contain more than one nucleus such as skeletal muscle and some other cells contain several nuclei.

The nuclear envelope surrounds the nucleus. i. e. largest organelle of the cell. It has a similar structure to that of

the plasma membrane. But the nuclear envelope contains tiny pores that allow a few substances to pass between it and outside the cytoplasm, i.e. the cell contents excluding the nucleus.

Therefore, the nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

To know more about the nucleus, refer to the below link:

Readme [11.4K]

Answer:

Phenotype

Explanation:

"only four phenotypes result from the six possible ABO genotypes. How does this happen? To understand why this occurs, first note that the A and B alleles code for proteins that exist on the surface of red blood cells; in contrast, the third allele, O, codes for no protein."
