Answer and Explanation:
Chemotaxis occurs when an organism moves toward a certain direction in response to a chemical.
Pollen is essential for the reproduction of plants because it produces a pollen tube that moves the sperm cells to the ovules that are located in the interior part of the flower. The pollen grains, produced in the anthers of a plant, <u>contain the male sex cells that will be transferred</u>. Chemotaxis plays a central role as it is a process in which chemical extracellular signals enable the movement of the pollen grains that will eventually enable plant reproduction.
<span>No crying underwater is not possible because of 2 reasons.
1) While crying there is a spasm of muscles , of that of the oesophagus (throat) and this would result in death of an individual if he/she is under water.
2) The external fluid pressure will not permit the tear gland to secrete tears there by nullifying the possibility.

Answer:
They are more attracted by the oxygen atom than by the hydrogen atom.
Explanation:
The bond between hydrogen and oxygen atoms in a water molecular is polar in nature. This is due to the differences in electronegativity of oxygen and hydrogen. Oxygen is much more electronegative than hydrogen.
The higher electronegativity of oxygen atom means that it attracts the electrons of the bond towards itself. Hence, the electrons of the bond between hydrogen and oxygen atoms in a water molecule are more attracted towards oxygen atom due to its higher electronegativity.
