Answer:
Cellulose
Explanation: The main functions of the cell wall are to provide structure, support, and protection for the cell. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants. The three layers are the middle lamella, primary cell wall, and secondary cell wall.
Answer:
Due to increasing the survival.
Explanation:
The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
The correct answer is option C.
The high energy molecules like FADH2 and NADH molecules provides electron and causes oxidative phosphorylation to generate more high-energy ATP molecules
All living things contain carbon so an argument could be made that carbon was the basis. Or it could be oxygen because all living things in one way require oxygen to live, even plants and fish who pull oxygen from the water molecules.
