Answer: Option (c) is the correct answer.

Explanation:

In warm air molecules have more kinetic energy. As a result, there are more number of collisions between air molecules. Hence, it rises more rapidly.

Whereas in cold air, molecules have less kinetic energy and thus they have less number of collisions between them.

Thus, in the diagram we can see that warm air begin to rise from position marked as 3 before colliding with cold air.

A decrease in the resting membrane potential is __________ whereas, __________ is an increase in the membrane potential.
nexus9112 [7]

Answer: depolarization; hyperpolarization

Explanation:

At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.

However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.

An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.

Bond [772]

Answer:Dehydration

Explanation:

Dark urine is usually indicative of dehydration; but there could be more reasons responsible for it. Ideally, when you eat or drink something, it goes through your digestive tract, circulatory system and then to your kidney. Kidneys are where everything is filtered and urine is produced. Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.
