Answer: True
Explanation: The plasma membrane is a membrane the protects the cell and its environment. It regulates what goes inside and what comes out of the cell. .
Plasma membrane as a structure composed of multiple components, including phospholipid bilayer, carbohydrates, and other lipids. The phospholipids possess one head and two tails. The head is basically polar and hydrophilic (water-loving) while the tails are non-polar and hydrophobic (water-fearing).
The plasma membrane is decorated with proteins. Some protiens are extrinsic proteins that run halfway through the membrane, while others are called integral proteins that go entirely through the membrane. The function of these proteins is to serve as channels to allow the molecules to enter and leave the cell.
Chromosome number varies from one organism to another. or example, humans have 46 chromosomes while bacteria have only one chromosome.
The problem associated with the chromosome number of various organisms faced by evolutionists is that with the decrease in the size of an organism, the number of chromosomes also decrease. Thus, it becomes difficult to find and study the chromosomes.
