The greatest amount of genetic variation is a sexual population is due to the processes of meiosis and mutation. Meiosis increases the genetic variation because of the recombination and independent assortment in the process, such that each gamete contains a different set of DNA, therefore the zygote produced during fertilization has a unique combination of genes.<span />
Answer:
Adaptations of the alveoli:
Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.

When a potato chip is put into salt water, the potato cells become flaccid (soft and floppy). This is because there is a higher concentration of water molecules inside the potato cells than outside. If more water enters the cell, it becomes turgid. This is important in supporting plants.
Protista are unicellular organisms that do have a nucleus. They can reproduce both sexually and asexually. They live in moist environments.
<h3><u>Explanation:</u></h3>
Kingdom Protista consists of the organisms that are unicellular or pseudo multicellular and they are eukaryotic in nature.
The classes under Protista consists of Chrysophytes, Dinoflagellates, Slime moulds, Euglenoids and protozoans. These organisms are all unicellular. They are all the eukaryotic organisms. Euglenoids are photosynthetic where the protozoans are consumers and Slime moulds are saprophytic. They prefer to live in water or moist lands. These organisms can reproduce both asexually or sexually.
