Answer:
b. phospholipid bilayer of membrane
Explanation:
The phospholipid bilayer evidently has in its structure mainly phospholipids, alcohol compounds and fatty acids.
Each molecule in the membrane phospholipid bilayer has two heads and a tail, both heads being hydrophilic (having affinity for water) and the tail being hydrophobic (having no affinity for water, and therefore repelling it).
This structure, with the heads, which are hydrophilic facing the intracellular and extracellular environments of cells, thus prevents the passage of polar compounds.
Answer:
Yes ,corals depend on the zooxanthellae (algae) that grow inside of them for oxygen and other things, and since these algae needs sunlight to survive, corals also need sunlight to survive.
Answer:
Vitamin d gives off energy which is from the sun
Explanation:
Cellular respiration is a process that converts glucose and other chemicals and substances into ATP (energy used by the cell). This is important because if we didn't have cellular respiration, we would not have energy to move our bodies and die off.
Those with the trait will carry on and reproduce and the offspring will have that same favorable trait, while he ones without the trait will die off and not reproduce. This is called natural selection.
