Living organisms use two major types of energy storage. Energy-rich molecules such as glycogen and triglycerides store energy in the form of covalent chemical bonds. Cells synthesize such molecules and store them for later release of the energy.
Answer:
stationary
Explanation:
It's called a stationary front because the gases remain stationary next to each other because neither is strong enough to replace another.
A
It is used to represent the number of atoms in the element. H2O is 2 Hydrogen molecules and one oxygen molecule, however we don’t wright the 1.
The correct answer is that during cross-pollination the pollen grains are carried from one plant to another plant. During self-pollination, the pollen and ovules are from the same plant.
In self-pollination, the pollen from the anther is deposited on the same flower's stigma, or on the stigma of another flower of the similar plant. In comparison, out-crossing or cross-pollination results in greater genetic diversity as the pollen grains and ovules are obtained from different plants.
I think that for 1 it’s either A or B as the kidneys and everything get air and the lungs release it.
For 2 is probably D as the others don’t really make much sense.
