It is important to note that the graph has 0 solar intensity for a long part of the day; around 16 hours. Only from 8 to 16 hours do we have significant sunlight.
This means that the length of day is very short during this time of the year;
The length of the day changes throughout they year; day is equal to night (12 hours each) during the solstices on March 21 and September 23 but during summer day is longer than night in the northern hemisphere; during winter it is smaller. THe smallest daylength is at December 21st (in the northern Hemisphere). This phenomenon is due to the tilt of the axis of the earth.
The correct answer is December 21; (if we talked about a place in the southern hemisphere, the answer would be March 21).
Answer:
The process that balance the the unfavourable entropic contribution from protein folding is the rearrangement of the water molecules around it.
Explanation:
Proteins are often in aqueous solutions. And around the protein, the water molecules are distributed in the way thermodynamically most favorable. So, the water molecules interact with the aminoacidic residues of the protein, making posible for the macromolecule to exist in solution.
During protein folding, are formed several interactions among the aminoacidic residues, which are responsible for the structure the protein adopts.
At the beginning it might seem this process shouldn't be possible, as the transition from one state to another more ordered one isn't spontaneous.
But as these new interactions are formed, an enormous amount of water molecules that were interacting with the protein are "released", being able to adopt several more configurations, in other words, gaining entropy.
In summary, the reduced entropy from the protein folding is balanced by the gain in entropy by the water molecules in the surrounding medium, which allows the process to occur.
Answer:
A. Red blood cells and muscle cells.
Explanation:
Cellular respiration which takes place in the presence of the oxygen is known as aerobic respiration and which takes place in the absence of oxygen is known as anaerobic respiration.
In anaerobic respiration, the cells produce a very low amount of ATP compared to the aerobic respiration but still in the human body to survive, the cells have this conserved process.
The cells in humans in which the process takes place are the red blood cells which do not possess the nucleus, the mitochondria and the other organelles so they perform anaerobic respiration. The muscle cells, when deprived of oxygen, undergo anaerobic respiration which produces a very low amount of ATP molecules and lactic acid also called fermentation.
Thus, option-A is correct.

Answer:
Forests store large amounts of carbon. When fossil fuels are burned, carbon from dead and decayed plants, animals and phytoplankton that lived hundreds of millions of years ago (before dinosaurs existed), is released into the atmosphere in the form of carbon dioxide. .
