During the first one to two months of life, infants are incapable of deep sleep (they do not have trouble falling asleep but they do not generally stay asleep for very long stretches). This happens because infants can’t make the difference between night and day - they do not yet have a circadian rhythm. Around six weeks, the hormone melatonin is produced (pineal gland) and it helps establish a normal sleep-wake cycle.
The best answer is C.
Enzymes are proteins that speed up the process of chemically breaking down food molecules. In other words they act as catalysyts. Catalaysts increase the rate at which chemical reactions occur without being consumed or permanently changed themselves.
A chemical reaction is a process that converts one or more substances known as substrates to another type of substance which is termed the product. As a catalyst, an enzyme can repeat the same type of reaction over and over again. Each enzyme has an active site where its specific substrate binds so that a reaction can begin to take place and continue to completion.
I'm pretty sure these include light availability, oxygen levels, water movement, salinity, density and pH. These conditions often vary from habitat to habitat and will either support or limit the life processes of the marine organisms living there.
Hopefully that's right.
Answer:
The answer is below
Explanation:
The lines of latitude run from the east to the west and is used to measure the distance from the north to the south of the equator. There are different lines of latitude such as the equator (0°), north pole (90° N), south pole (90° S).
The North and South poles are most similar to the plate with an axis angle of 80° because sunlight hits these points at least at an axis angle of 80.
