Answer;
Vesicles containing neurotransmitter.
Explanation;
-Neurotransmitters are released by secretion from the ends of axonal terminals.
-Synaptic vesicles store various neurotransmitters that are released at the synapse.
-Neurotransmitters are released from the axon terminal when their vesicles "fuse" with the membrane of the axon terminal, spilling the neurotransmitter into the synaptic cleft.
Answer:
DNA is a self replicated material that is inside almost every living animal, and human being. DNA contains genetic codes. Dna holds genes, for example those who created you, there genes are passed on to you causing it to also be in ur DNA. It contains instructions that an organism needs to live, develope and reproduce. DNA serves as the primary unit of heredity in different types of organisms. (It might not be long enough but maybe this could atleast be used as half a paragraph)
I’m not sure if I’m exactly right but I say coral bleaching.
Answer:
The correct answer would be natural selection.
Natural selection favors the survival and reproduction of the organisms which are better adapted to the environment.
It gradually changes the allele frequency or heritable characters of a population over the generations.
Similarly, during malaria outbreak organisms which are better adapted or resistant against the disease will survive and reproduce successfully. It will increase the frequency of allele associated with resistance or adaptation against malaria.
For example, the carriers of the sickle cell anemia show protective advantages against malaria.
