Answer:
C. Some bacteria.
Explanation:
Firstly here, nitrates bacteria turn ammonia compounds into nitrites by combining them with oxygen.(Nitrites are chemicals with less oxygen in their molecules than nitrates).
Secondly, nitrate bacteria combine nitrites with more oxygen to form nitrates. By this sequence, nitrogen in proteins is changed into a form which can be absorbed by plant roots. The same series of bacteria also form nitrates out of the nitrogen-containing compounds in animal droppings and urine.
Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
Answer:
The correct answer would be D) In a population of herbivores, a change in the habitat provides leaves that are high up in the trees. The herbivores with longer necks can reach the leaves. They survive and reproduce. The herbivores, over time, have longer necks.
Natural selection is a gradual process which favors the survival and reproduction of organisms which have better adapted to the environment.
Adaptations or traits which favor the survival of the organisms in environment keep on passing from one generation to the next and with time theses traits get inherited in the population.
For example, in the above situation herbivores with short necks die as they could not reach the leaves that were high up in the trees. In contrast, long neck favors the survival of the organisms due to which only organisms with long necks survive and reproduce. With time, only organisms were left that had long necks.
Answer:
As the question is incomplete i have added the full question in the ask for detail section of this question.
There will be DECREASE in phospholipipids, and triglycerols formed from DAG by the activation of phosphatidylethanolamine and head groups.
while on the other hand there will be INCREASE in phospholipids formed from polar head group, CDP-DAG, Phosphatidylinositol and Phosphatidate.
A because binary fission copies the dna and each daughter cell gets one strand
