I think it should be D. A loss in biodiversity due to catastrophic event.
Answer:
B. locus ceruleus.
Explanation:
A nucleus present in the pons of brainstem responsible or involved in physiological responses to panic and stress is known as locus ceruleus.
Basically, locus ceruleus is responsible for the primary production of norepinephrine in the brain. The nucleus transfers the norepinephrine to whole cerebral cortex along with various other structures like amygdala, cerebellum, hippocampus, and spinal cord.
So, when there is a panic disorder due to norepinephrine dysregulation at the brainstem area which will be definitely locus ceruleus.
I'll answer what i can
Answer:
Its recommended because it can help fight the flu if you get it
It affects the immune system by training it to target the flu, and gain resistance to it
The best time is during cold, due to the fact that cold helps the virus (heat kills some viruses)

Its important for the CDC to update it every year because the flu isn't always the same, and can adapt to the shot to where it has no effect.
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.
