Answer:
Mammals
Explanation:
Mammals are a large group of animals that can be subdivided into multiple species, more than fish and insects. I cannot be D because plants are not animalia
Alternative Splicing is a regulated process during gene expression that results in a single gene coding for multiple proteins.
In neurogenic shock, the characteristic mechanism is the reduction of sympathetic outflow from the brainstem leading to the decreased in the blood vessel tone and eventually vasodilation. In the presence of vasodilation, there will be decreased blood pressure and eventually shock. Since there is reduced sympathetic outflow, there will also be a decreased heart rate, warm skin (from the vasodilation), and dry skin (from the reduced cholinergic stimulation of the sweat glands).
Question number 1.
The correct answer is: The insects are the same species.
There is still a lot of discussion in the scientific community on how should we define a biological species, but one of the main points that all scientists agree on is that the members of the same biological species are individuals that can successfully reproduce and leave viable and fertile offspring.
Question number two
The correct answer is : The graph showing directional natural selection.
In the case of the fish species of the coral reef, there are two extremes of the phenotype the dark orange and the pale one.
Before the bleaching of the coral, the dark orange phenotype was better adapted to the environment. But after the bleaching of the coral, the pale phenotype now resembles the coral background more and it is able to hide from the predators better than the dark orange one.
This will result in natural selection favoring the pale phenotype more and working in the direction of this extreme on the graph.
