Answer:
Explanation:
Solution:
Experiment:
Boiled potato is used here in mashed form and separated into three parts.
Separate them in test tube A, test tube B and test tube C.
In the test tube A, iodine is added.
In the test tube B, iodine is added and then saliva is introduced.
In test tube C, nothing is added and kept as the control set.
Observation:
The test tube A, the iodine solution changes the boiled potato to blue color.
In the test tube B, saliva is introduced and mixed with the sample after adding iodine.
As a result, the color change will be observed when starch will be broken down to simple sugars like maltose.
The blue color starts reducing in the test tube B as the saliva containing the salivary amylase starts acting on the starch.
Test tube C shows no color change.
Inference:
The change in the test tube containing saliva shows the effect of salivary enzymes like salivary amylase on the boiled starch present in potato.

The correct answer is option B
The mammals are further classified into groups in terms of development of the offspring. There are various types of mammals that development in different way.
Placental Mammals:
The embryo grows inside the body of the mother by the help of placenta which aids in the nourishment of the embryo. After birth, the mother cares for the young ones.
Marsupials:
They lack placenta and in place of placenta they have marsupium that provides nourishment to the young ones after birth. This is a pouch found in the body of the mother which acts as the protective covering of the embryo in which further development of the young ones takes place.
Monotremes:
These kind of mammals lay eggs, eggs are hatched and the young ones lick the milk from the abdomen of the mother.
Some viruses consist only of a protein coat surrounding a nucleic acid core. If you wanted to radioactively label the nucleic acids separately from the protein, you would use radioactive nucleotides.
To selectively label the nucleic acids separate from the protein in viruses, radioactive nucleotides are utilized. These radioactive nucleotides contain a radioactive isotope and can be incorporated into the viral nucleic acids during processes like replication or synthesis. This incorporation enables the specific labeling of the genetic material while leaving the protein coat unlabeled.
Researchers use this technique to trace and investigate the behavior and interactions of nucleic acids, providing insights into viral replication, gene expression, and various molecular processes. Radioactively labeled nucleotides, such as tritiated thymidine (3H-thymidine) or 32P-labeled phosphate groups, have been instrumental in advancing our understanding of nucleic acid biology and have applications in fields ranging from virology to molecular genetics.

Answer: Phosphorous
Explanation:
Phosphorous can be used to label Nucleic acid. Nucleic acids can be modified or labelled using tags .
Some common materials or substances that can be used to label nucleic acids are flurophore, enzymes, radioactive phosphorous, biotin et cetera.
The nucleic acid of virus is labelled using phosphorous. When this virus will infect the host cell then nucleic acids will be seen separately.
