Answer:A). Phospholipids
Explanation: A cell membrane is a phospholipid bilayer. Phospholipids have two components: the fatty acid chain and the phosphate head group. The phosphate groups of the phospholipids are polar while the fatty acyl chains are nonpolar. The nonpolar fatty acyl chains face each other forming a bilayer while the phosphate head group face outward interacting with the environment. The cell membrane contains other components such as the proteins and carbohydrate chains but in lesser amount, therefore the major constituent of the cell membrane is phospholipids.
Answer:
For a cladogram the closer the organisms are, the closer they are related.
Explanation:
Each branching off represents a change in the species, so the closer they are, the more traits they will share
Answer:
Option (2).
Explanation:
Skin may be defined as the largest organ of the body. Skin provides the first line of defense in the organisms. The skin secretes different enzymes and chemicals that kill the pathogens.
The patient with the burned skin are more susceptible to the pathogen and has weakened immune system. To cover the burned skin surface, skin can be taken from the other body parts as the skin has the same property and shows the same antigen as the replaced skin.
Thus, the correct answer is option (2).
Answer:
c) Both electron transport and ATP synthesis would stop.
Explanation:
We need oxygen to survive. Absence of oxygen can make can lead to one's death. This is because we need oxygen so that our cells can use it during oxidative phosphorylation, the last stage of cellular respiration. Oxygen is found at the end of the electron transport chain, where it accepts electrons and picks up protons to form water. Absence of oxygen at this stage will make the electron transport chain to stop running, and ATP will not be produced.
