Answer: A. Cool
Explanation:
The diagram shows that moving from the left to the right indicates a lower temperature and the arrow is pointing to stars to the right which means that they are cool in comparison to those on the left.
Red stars like the one being pointed to are the cooler stars with temperatures of less than 6,000 Kelvin as opposed to blue stars which are very much hotter and go above 10,000 Kelvin.
Antarctic fish species requires an adaptation to cold environment. Living at cold temperature environment would demand certain biological responses such as cutaneous respiration, enlarged blood vessels, and producing greater amounts of fat. Most of these fat are composed of higher phospolipid levels which are primarily due to phosphatidylethanolamine. This phospolipid is responsible for destabilizing cell membranes and make it more fluid thereby allowing unrestricted blood flow. The fatty acid composition of the membrane lipid is important for membrane fluidity, this is mainly attributed to unsaturated fatty acids which are responsible for decreasing the order of membrane lipids thereby decreasing viscosity. At extremely low temperatures, organisms with low concentration of unsaturated fatty acids would freeze cell membranes. That's why antarctic fishes have higher levels of unsaturated fatty acids.
Answer:
First, rain will have to occur. The lake and surfaces will have water in them, after that it will a while for the surface to evaporate into water vapour, after that the water vapour will condense into water droplets and when the clouds are too heavy because of too much water droplets in them, it will start to rain again and this cycle will keep going on continuously.
