Answer:they won't for a pair
Explanation:Basically it all depends on process called complementary base pairing, the structure of thymine and adenine is such that it forms two hydrogen bonds and therefore pair up
2.guanine and cytosine have such structure that they form three hydrogen bonds and pair up
So Adenine complements only thymine and guanine complements cytosine and there aren't any chances of guanine pairing up with thymine.
Inferiority, as he would feel inferior to his peers.
True. The brain have different waves that occur at every stage of consciousness. For instance, when the individual is in awake state, beta waves are associated.Thank you for your question. Please don't hesitate to ask in Brainly your queries.

2. It carries water from the roots to the leaves.
Explanation:
Phloem is the vascular tissue in charge of transporting and distributing organic nutrients.
Answer:
The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it indicates low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.
Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb, decrease affinity and easily unloaded to muscles.
<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.
As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules binding by Hb, and easy release to respiring cells.
