Retina receives lights and transfers it to the Optic Nerve
Answer:
B. Proteins
Explanation:
Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).
Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.
Nucleotides lining up along the template strand according to base pairing rules process helps to preserve the genetic information stored in DNA during DNA replication
Option D
<h3><u>Explanation:</u></h3>
The DNA is a semi conservative molecule from the genetic information storing point of view. The genetic information is stored there in form of the alignment and arrangement of the nitrogen bases. These nitrogen bases are replicated just in order to conserve the genetic information.
During protein synthesis, same nitrogen bases get denoted in the RNAs and this gives the particular protein which is required in the body. No molecule present in the body can destroy the DNA and its alignment. It’s conserved as long as no external molecule or force destroys it. So it’s conserved in a very safe way.
<span>The answer is I, II and III. These
microbes can be funds even in hydrothermal vents at the bottom of ocean
trenches where they convert chemicals to organic matter. Most are critical in
the many nutrient cycles such as the nitrogen and carbon cycles. These microbes form the
base of the food chain since they support higher organisms such as paramecium
which are in turn eaten by higher organism such as amoeba. The amoebas are then
fed by tadpoles, for example, and the tadpoles are eaten by fish…and etcetera. </span>
