Answer: The genetic material must be a DNA double helix.
Explanation:
Genetic material is the material which resides in the nucleus or any other organelles within the cell which is responsible for development of traits in an organism. It is a hereditary material which passes from parents to their offsprings. It is not necessary the genetic material must be stored in the form of double stranded DNA instead it can be stored in the form of RNA which is single stranded genetic material it directly encodes for proteins during translation.

Embryogenesis is the process of development of an embryo from zygote. In embryogenesis, the zygote undergoes repeated cell division through mitosis. The divisions help in the growth of an embryo. Cells undergo differentiation attaining specific shape, size and function. Cell differentiation occurs at specific location resulting in the production of different tissue, organs and organ system.

Answer: Micro villi
Explanation:
The cellular structures that increases the superficial surface area of the cell is known as micro villi. It is an extension of cell membrane.
This structure helps in the increasing the surface area for the maximizing the absorption of food materials.
It also helps in providing a large area in a very compacted space. It is found at many places in the human body such as in small intestine.
Answer:
True.
Explanation:
Genetic drift occurs when a species migrates into another one, therefore making a new variation of the species.
