Viruses cannot reproduce. they instead copy themselves with the help of a host cell. a cell can reproduce and doesn’t need help from other cells
The modern taxonomists classified organisms on the general basis of evolutionary, morphological, and genetic traits
Explanation:
- Evolutionary relationships provides the phylogeny of evolutionary ancestors and descendants
- Homologous structures are structures which look the same but perform different functions
, like bones of a human leg compared to bones on a bird's wing
- Analogous structures have different structure but same function like an insect’s and a bird’s wing
- Embryo developmental pattern and similar relationships
- Similarities in DNA and protein sequencing in related organisms
The above basis provided modern taxonomists to classify organisms according to the various disciplines like Genetics, Cytology, Embryology, Physiology, Anatomy and many more.
Answer: The correct answer to the question is option C
VITAMIN D
Explanation: Vitamin D is one of the essential vitamins needed by the body,it is fat soluble and plays a vital role in increasing the rate the body( intestines) absorbs calcium,phosphate and magnesium.

Vitamin D helps in the absorption of Calcium in the body and calcium helps in the strengthening of bones of the body.
Vitamin D is very vital in the maintainance of bone strength as well as act as a form of hormone that helps in the regulation of the growth and development of other tissues in the body.
