Answer:
The inactive precursor to the enzyme pepsin that digests proteins in the stomach. (Ans A)
Explanation:
Pepsin is known as a digestive enzyme which is present in humans and other species digestive system. It is produced by the stomach, where it helps to digest the proteins and break down into amino acids which are present in food. In the stomach, a cell is known as a peptic or chief cell that helps to release Pepsinogen.
The Pepsinogen secreted by Chief cells is an inactive form of pepsin, on exposure to HCL (hydrochloric acid secretion from Parietal cells), gets converted to the active enzyme pepsin because HCL provides necessary acidic environments where pepsin work best. Then Pepsin hydrolyzed the proteins to polypeptide and starts protein digestion in the stomach.
Answer:
1. false as a hypothesis is an educated guess so
2. share the experiment please
3.independent
4.A
Answer:
Explanation:
Reptile shows temperature dependent sex determination where the temperature determines whether the reptile such lizard is either a male or female during embryonic development. In America dragon lizard where the ZW chromosome determination is used, at a very high incubation temperature there is a change from a genotypic male with genotype ZZ to a phenotypic female with genotype ZW or ZZ. Hence an increase in temperature will lead to reverse of a male genotype to female phenotype.
Answer: <u>rTMS
</u>
rTMS uses magnets to stimulate the areas of the brain.
EEG uses metal discs which are attached to the scalp of the person, but these don’t provide any energy or input to the brain. So it is an incorrect answer.
EMDR uses movement of eyes to detect any symptom of trauma. Again, incorrect answer.
REBT is a kind of a psychological therapy, so it doesn’t use any device or instrument. So, it is a wrong answer.
The water would move out since it’s moving from high concentration to low concentration.
