Biology

  1. By insects: When a bee, butterfly, etc. try to get the sticky sweet pollen inside a flower, the pollen catches on to the insect, too. Then when the insect goes to the next flower, the pollen in pollinates. Note that this is <em>not</em> on purpose.

    2.  Another way plants are pollinated is by the wind. The wind picks up pollen from one plant and blows it onto another. Note that this is by nature.


I hope that helps! :)

Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.

Anni [7]

Answer:

A. Activated B - cells divide to form memory cells.

Explanation:

The vaccine contains the dead version of the respective virus, so that virus will be inactive and it will become easy for the WBC to kill it and antibodies will be formed.

This is done because if we get infected by the virus, our body cells (WBC) will remember that how they killed the first entered virus (the dead version) and it will be easy for them to kill the active virus as they know the antibodies which were formed to kill the inactive virus.

HOPE IT HELPS YOU

Why do birth control pills contain hormones?
Kipish [7]

Birth control pills contain mam-made forms of two hormones called Estrogen and Progestin. Both hormones prevent a woman's ovary from releasing an egg during her menstrual cycle. They do this by changing the levels of the natural hormones the body makes.
