1.

A cell may be defined as a small mass of protoplasm containing a nucleus.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
This statement is true because a cell is indeed a small mass of protoplasm that contains a nucleus. Protoplasm is the living substance within a cell that carries out various functions, and the nucleus is the control center of the cell that contains the genetic material. Therefore, a cell can be defined as a small mass of protoplasm containing a nucleus.

- E.
  
  The excretion of waste products.
- F.
  
  Some cells have the power of movement.
Correct Answer(s)
B. The absorption of nourishment.
C. Growth and repair.
D. Reproduction by division.
E. The excretion of waste products.
F. Some cells have the power of movement.

Explanation
Cells are capable of absorbing nourishment, which is essential for their survival and functioning. They also have the ability to grow and repair themselves, allowing them to adapt to changes in their environment. Reproduction by division is another characteristic of cells, enabling them to multiply and create new cells. Cells also excrete waste products, removing harmful substances from their internal environment. Additionally, some cells possess the power of movement, allowing them to migrate and perform various functions within the organism.

The nucleo-protein consists of a number of minute threads called chromosomes, and the human cell contains 26 chromosomes.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement that the human cell contains 26 chromosomes is false. The correct answer is false because the number of chromosomes in a human cell is actually 46. Chromosomes are thread-like structures made of DNA and contain genes that carry genetic information. In humans, there are 23 pairs of chromosomes, with one set inherited from each parent, resulting in a total of 46 chromosomes in each cell.

A tissue is a collection of similiar cells subject to the same laws of growth and development, e.g. muscle tissue, bone tissue.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because a tissue is indeed a group of similar cells that perform a specific function and have a common origin. These cells work together to carry out a particular task in the body, such as providing support, movement, or protection. Each type of tissue, like muscle tissue or bone tissue, follows the same laws of growth and development, making the statement accurate.

6.

Connective tissues are supporting tissues, binding, covering and protecting other tissues, and the main types are :- (Select Six)
- A.
  
  Fibrous
- B.
  
  Globules
- C.
  
  Adipose
- D.
  
  Lymphoid
- E.
  
  Cartilage
- F.
  
  Areolar
- G.
  
  Bone
Correct Answer(s)
A. Fibrous
C. Adipose
D. LympHoid
E. Cartilage
F. Areolar
G. Bone

Explanation
Connective tissues are a diverse group of tissues that provide support, structure, and protection to other tissues in the body. Fibrous connective tissue is made up of strong fibers and is found in tendons and ligaments, providing strength and flexibility. Adipose tissue is responsible for storing fat and providing insulation and cushioning. Lymphoid tissue is involved in the immune response and includes lymph nodes and tonsils. Cartilage is a firm, flexible tissue found in the nose, ears, and joints, providing support and cushioning. Areolar tissue is a loose connective tissue that surrounds and supports organs and blood vessels. Bone tissue is hard and rigid, providing support and protection to the body.
