Dinoflagellate is a type of neurotoxin which is found in the red-tide algae.
The answer is:
d. people can get paralytic shellfish poisoning during dinoflagellate blooms
Dinoflagellate algal blooms, during red-tide, release strong neurotoxins that can be ingested by shellfish and passed on to humans who eat the infected shellfish. The most significant public health problem that has been known to cause this harmful algae poisoning is: Amnesic Shellfish Poisoning (ASP).
A neuron (also known as nerve cell) is an electrically excitable cell that takes up, processes and transmits information through electrical and chemical signals. It is one of the basic elements of the nervous system. In order that a human being can react to his environment, neurons transport stimuli.
I would go with B & D because they change over time and they can go extinct like those big octopus in the oceans, they are rare to see in my opinion because they can blend in with other things that keeps them away from danger.

Biennial plants</h2>
Explanation:
This plant is a biennial, which means it will just take longer than a season to mature enough to produce flowers.
Since the Sweet William plant did not flower last year when it was planted and this year also it did not bud till the spring. So, we can assume that these plant will need atleast two seasons to mature hence they are biennials.
Depending on the life span, plants are classified as annuals (one season), biennials(two season) and perennials (more than two years).
