Explanation

Amoeba, Euglena, and Paramecium are all unicellular organisms.

They consist of a single cell that performs all the functions necessary for survival, such as movement, reproduction, and obtaining nutrients.

Explanation

Meiosis is a type of cell division that reduces the chromosome number by half and is essential for the formation of germ cells (sperm and egg).

It ensures genetic diversity.

It is fundamental to sexual reproduction.

Explanation

The nucleus is the most important part of the cell as it controls all the activities of the cell, including growth, metabolism, and reproduction.

It contains the cell's genetic material (DNA) which regulates gene expression and directs protein synthesis.

Explanation

Robert Hook described the cell as: Basic unit of life

Robert Hook  discovered cells: 1665

Cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body

Explanation

The overall three-dimensional structure of a polypeptide is called its tertiary structure.

These include :

hydrophobic interactions,

ionic bonding,

hydrogen bonding 

disulfide linkages.

Explanation

More details about this question will be shared soon.

Explanation

A slippery outer covering in some bacteria that protects them from phagocytosis by host cells is Capsule.

Capsules can protect a bacterial cell from ingestion and destruction by white blood cells

Capsules confer resistance to phagocytosis.

Explanation

Agranulocytes are one type of white blood cell that contain no distinct granules in the cytoplasm.

Agranulocytes originate from Lymphoid tissue, and their nucleus is not lobed. 

Explanation

The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands

Explanation

The human egg (ovum) is the largest cell in the body and a nerve cell is the longest cell in the human body.

The sperm is the smallest cell in the human body
