<em>Answer:</em>
<em>The answer for this statement is "True".</em>
<em>Explanation:</em>
<em>In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood vessels (the countercurrent exchanger). This relationship establishes and maintains an osmotic gradient extending from the cortex through the depths of the medulla that allows the kidneys to vary urine concentration dramatically which is true.</em>
Hypophyseal portal system allows the hypothalamus to have direct communication with the anterior pituitary.
The hypophyseal portal system is a network of blood vessels that connects the anterior portion of the gland and hypothalamus at the base of the brain. Two capillary beds, one in the median eminence and the other in the anterior pituitary, make up the portal system. Its principal job is to swiftly transfer and exchange hormones between the anterior pituitary gland and the hypothalamic arcuate nucleus.
The cortisol, androgens, and aldosterone hormones interact with anterior pituitary gland cells via travelling through the hypophyseal portal system. Hormonal signaling through the hypophyseal portal system enables connection between these two structures.

Climate change is the variation in the climatic factors and attributes like temperature and weather conditions of a region that can result in warming, ice melts, acidification etc.
Species cannot adapt fast enough to survive the change in their environment.
<h3>What is natural selection?</h3>
- Natural selection is the biological process of selecting the fit organism with better traits and qualities compared to another.
- It is a mechanism of evolution that help organisms to adapt to altered conditions and makes them more likely to survive in the conditions.
- Due to rapid climate change, the organisms are not able to adapt to the altered conditions.
Therefore, option C. is the correct option.
