Answer:
Option-
All of the given disorders and elements which causes them are correct.
- Proteins and other related minerals are required for the better functioning of the human body, as there can be a lot of complications faced by the over all system of the human body if there are low or inadequate level of proteins and minerals inside the human body.
Explanation:
While, the following disorders and causes of the protein and nutrients deficiency can be described as follows:
- Beriberi is rare in the United States.
- Alcohol-related thiamin deficiency is called Wernicke-Korsakoff syndrome
.
- Most adults get adequate riboflavin in their diets.
- Thiamin deficiency causes diarrhea, dermatitis, and dementia
.
- Since humans can synthesize niacin from tryptophan, they do not need to consume it.
Answer:
The lining in the womb becomes thicker and spongy to protect the embryo/foetus in all stages of life inside the womb and to stop damage/harm coming to it
Explanation:
<h2>(D) is the correct option </h2>
Explanation:
- Both the stapedius and tensor tympani are striated muscles
- The stapedius is about 6 mm in length, arises from the pyramidal process and the tendon attaches to the posterior neck of the stapes
- The stapedius is a muscle with a high oxidative capacity
- The tensor tympani is about 25 mm in length, the muscle is not as strong as the stapedius, and the tendon also contains more elastic tissue and fat
- The tensor tympani courses through a bony canal in the wall of the anterior middle ear, and attaches to the neck of the manubrium
- The tensor tympani and stapedius muscles are protective reflexes
- They reduce the amount of sound that gets into the inner ear
- They are somewhat similar to the blink reflex thus they can be triggered by loud noise, and when they go off, both ears can be involved
- If stapedius and tensor tympani muscles is not present then loud sounds would cause the ossicles to move too much, potentially causing damage to the inner ear
The hydrogen bonding of nucleotides into a new DNA molecule is facilitated by enzymes. Hydrogen bonding is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pairs forms two hydrogen bonds while the C-G pair forms three. The enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds.
