During endocytosis the plasma membrane folds inwards either through phagocytosis for solits or pinocytosis for liquids.
During exocytosis vesicles for the inside of the cell fuse with the membrane and are released outside of the cell.
The answer is B to the question
The axons of the olfactory sensory neurons project to the olfactory bulb in the brain. This part is found in the forbrain and is responsible for the sense of smell. Inside this bulb are spheres of tissue that are called glomeruli. They are from the ends of branching axons.
Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
I had to take a screenshot of my response since it was getting flagged for being inappropriate for some reason.
