Answer:
D
Explanation:
results is the only one that makes sense because results mean what you end up with
The sun is the ultimate source of energy because without the sun producers could not produce food for themselves which would then leave no food for consumers.
Primary producers are the original source of food in the vent ecosystem, using chemical energy to create organic molecules. All other life depends on primary producers, and they have the greatest biomass in the community.
Primary consumers get their energy directly from the primary producers by eating or living symbiotically with them.
First order carnivores prey on the primary consumers and in turn are eaten by other animals.
Top order carnivores eat other consumers and carnivores but are rarely hunted by other creatures. Because they are separated from the primary food production by several layers, top order carnivores have the smallest biomass in the food web.
Answer:
POINT MUTATION (SUBSTITUTION)
Explanation:
A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.
This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.
