xxTIMURxx [149]

Answer:

e.)  If exposure to cowpox gives immunity to smallpox in milkmaids, then milkmaids have a natural immunity and their blood should be used to develop a smallpox vaccine.

Explanation:

  • Milkmaids who suffered from cowpox did not suffer from smallpox i.e. they were immune to the disease.
  • If milkmaids did not suffer from smallpox then there must be some element of immunity that they received once they had recovered from cowpox, this would likely be found in their blood as antibodies.

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:
