Answer:
Ralph is looking at a vein (likely a muscular vein).
Explanation:
Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves. This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.
Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.
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.
