<u>Answer</u>:
The organic chemicals that helps cell membranes to conserve the internal fluids are phospholipids.
<u>Explanation</u>:
Phospholipids are used to form plasma membrane of the cell. Plasma membrane surrounds the cell contents like various cell organelles, nucleus, ribosomes and proteins. A phospholipid molecules is made up if a polar head containing a phosphate group and the two non-polar tails made of long chains of hydrocarbon of fatty acids.
The another name for plasma membrane is phospholipid bilayer. The polar head is hydrophilic that interactes with polar environment while facing outside the bilayer while the non-polar tail is hydrophobic in nature which makes the internal hydrophobic region of cell membrane which faces inside the bilayer.
Answer:
D.electrical signals and chemical neurotransmitters
Explanation:
chemical transmitters are the language that neurons use to connect eachother.
Remember that the number of electrons are equal to the number of protons, and to find the number of protons you have to look and see the atomic mass of the atom is equal to the number of protons, and to find the number of neutrons you have too subtract the atomic mass to the atomic number.
Example:
You want to find out how many protons, neutrons, and electrons are in Platinum:
- Atomic number is equal to the number of protons:
- So platinum has 78 protons and electrons.
- Subtract atomic mass to atomic number:
(forgetting about the decimals)
So platinum has "78 protons, and electrons, and has 117 neutrons."
Hope this helps!
