<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.
Asexual reproduction is better because it is more convenient!
1. It only requires one organism
2. Results in more offspring
3. Usually a quicker process
OR
Sexual reproduction is better because it results in more genetic diversity!
1. Requires two organisms of the same species
2. Genetic material mixes together to create a random, unique combination
3. Recombination of genes decreases the chances of defects, diseases and mutations
Hope this helped some! :)
