Both photosystems contain many pigments that help collect light energy, as well as a special pair of chlorophyll molecules in the heart (reaction center) of the photosystem. The special pair of photosystem I is called P700, while that of photosystem II is called P680.
The amount of energy available from the organisms within a tropic level determine the carrying capacity of the next tropic level
Explanation:
As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those <u>Located near the heart, because they are absorbing the most shock.</u>
<u></u>
Explanation:
When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.

Proteins that are embedded within, and extend across, the phospholipid bilayer are called <u>Integral Protein</u>.
Integral Protein- Any protein containing a unique functional area for the purpose of ensuring its location within the cellular membrane is referred to as an integral protein, which is also referred to as an integral membrane protein. Or, to put it another way, an integral protein seizes the cellular membrane.
Cellular membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
