Leaves get their colors through pigments. Leaves turn green because of chlorophyll but when they turn orange red and yellow it’s the chlorophyll breaking down and mixing with pigments (like carotenoids)
I think you forgot to give the options along with the question. I am answering the question based on my research and knowledge.

Lets consider the water drop as being part of the water in a lake. The water droplet evaporates and changes from a liquid state to a vapor state by gaining energy and travels up to the upper atmosphere. In the atmosphere the water droplet once again condenses in the clouds and is stored until it can be precipitated on to the land again in the form of rain or other forms of precipitation.
Answer:
B. The conditions in their muscles have become anaerobic.
Explanation:
In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.
What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.
Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".
Answer:
specificity
Explanation:
Adaptive immunity or specific immunity refers to the defense mechanisms of the body against specific invading agents. Adaptive immunity exhibits specificity and memory, the features not exhibited by innate immunity. The specificity of immune system serves the ability of the immune cells to identify specific pathogens or foreign molecules and produce an immune response against them.
It also involves distinguishing self from nonself molecules. The B cells and T cells have specific receptors that recognize and bind to specific antigens only and produce an immune response against them only while not responding to the other antigens.
