A. Nutrients and other materials pass through the cell membrane through the process of diffusion. This allows the cell to perform all the activities it requires for daily maintenance and living. The concentration gradient allows the cell to regulate just how much of a certain material passes through it.
The difference between diploid and haploid cells a duplicated chromosome consists of two sets of chromosomes.
The diploid cells consists of two sets of chromosomes whereas the haploid cells consists of one set of chromosomes. The haploid cells are formed by the process of meiosis and the diploid cell formed by the process of mitosis.
In the higher organism, such as human the gametes are haploid and beside their all cells are diploid. The diploid cell when reproduce or increase their number through mitosis they form identical copy of its chromosomes.
The examples of diploid cells are nerve cell, bone cell, etc. And the examples of haploid cell includes gametes.

Answer: C). Sensory neurons, D).motor neurons
Explanation: Sensory neurons are nerve cells that carry signals from the external parts of the body such as the skin, eyes, ear, nose (the sense organs) to the brain.
Motor neurons are nerve cells that carry information or messages away from the central nervous system ( brain and spinal cord) to the rest of the body such as the skin, muscles and glands.
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
