d. It is a bacterial strain consisting of protein and a DNA core.
Answer:
<u>Option-(A, C):</u> It is a type of virus that infects bacteria, and it is a virus consisting of a protein coat and a DNA core.
Explanation:
- The bacteriophage is a form of unicellular cell that comprises of a very specific form of structure, having the genetic materials intact inside the protein coat and the rest of the body is termed to be more of a crystalline in nature. As, the phage is categorized for having the main host as the bacterial cell, and it replicates itself by using the two main pathways which are the following:
- Lytic cycle,
- Lysogenic cycle.
The energy used by cells in their internal processes is called ATP. ATP stands for Adenosine Triphosphate.
Some info / facts about ATP:
- ATP is an organic chemical.
- ATP is used by cells, but it can also be produced in living organisms.
- ATP is a nucleotide (an organic molecule that builds up DNA or RNA).

Answer:
Elements and compounds cannot be broken down into simpler substances by an ordinary process because of the following reasons.
1) Elements cannot be broken down by chemical or physical methods because elements is composed of atoms which are indivisible.
2) Compound cannot be broken down into simpler substances by ordinary process because elements present in the compound are combined with each other chemically.
