Answer:
<u>D. There is less available energy in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels.</u>
Explanation:
Each successive trophic level contains about ten percent of the available energy from the previous trophic level. The other ninety percent is lost as heat to the atmosphere through metabolism by the organisms in that level. Therefore, there will be much less energy in the fourth trophic level.
The phosphodiester bonds of the polynucleotide backbone in DNA would be broken.
The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide in DNA molecule (or hydroxyl groups in phosphoric acid react with hydroxyl groups on 3' carbon atom of one sugar molecule (deoxyribose) and the 5' carbon atom of another sugar molecule (deoxyribose) to form two ester bonds).
Hydrolysis of phosphodiester bonds is catalyzed by the action of enzymes phosphodiesterases.
Answer:
The correct answer will be option-E
Explanation:
The autonomic nervous system or ANS activity in the brain is mainly controlled and regulated by the hypothalamus structure. The autonomic centres of the hypothalamus control the hormonal secretion adrenal medulla like adrenaline and norepinephrine.
The secretion of the hypothalamus controls the activity of the vasomotor center which help maintain the blood pressure.
Thus, option-hypothalamus is the correct answer.

Answer:
The herbivory by the white-tailed deer
Explanation:
The independent variable can be defined as the variable that who's values do not depend on those of another.
The independent variable in this case is the herbivory by the white-tailed deer which is divided into two categories.
The dependent variables is the response of the corn to the independent variable which are measurements to be taken as shown in the question; the height of the corn plants and the number of ears or corn each plant produces.
