Answer:
The correct answer is two layers of phospholipid with their polar hydrophilic heads facing away from each other.
Explanation:
The plasma membrane is composed of phospholipid bilayer in which the protein molecules are embedded .Each phospholipid of the phospholipid bilayer contain a glycerol head group that are arranged in the extracellular region away from each other.
whereas the fatty acid chain of the the phospholipid molecules of both the layer faces each other in the hydrophobic region of the plasma membrane.
when an organism of many cells breaks up into two or more parts and these parts survive to produce a new organism , reproduction occurs by fragmentation.
Answer:
Option (2).
Explanation:
Hemoglobin may be defined as red color pigment present in the red blood cells. The main function of hemoglobin is the transport of oxygen molecules in the body.
Various factors can affect the binding of oxygen with hemoglobin. The higher the partial pressure of oxygen, more oxygen will bind to the hemoglobin and transport faster in the blood. Low partial pressure decreases the binding affinity of oxygen with hemoglobin. All other factors mentioned in the questions are correct.
Thus, the correct answer is option (b).
Answer:
A
Explanation:
because they more closely related
Answer:
Because salt is an agent that attracts and draws out water, the surrounding salt water draws water from inside the fish so they must constantly drink water to replace the lost water in their system. The process of water being drawn out of the body by the surrounding water of higher salt levels is known as osmosis.
