Explanation
The statement is true because a cell is indeed a small mass of protoplasm that contains a nucleus. Protoplasm refers to the living substance within a cell, which includes the cytoplasm and the nucleus. The nucleus is the control center of the cell, containing genetic material and regulating cell activities. Therefore, a cell can be defined as a small mass of protoplasm that contains a nucleus.

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 and replace damaged or old cells. Some cells, such as muscle cells and sperm cells, have the power of movement, enabling them to perform specific functions within the body.

Explanation
Mitosis is the correct answer because it refers to the process of cell division, where a single cell divides into two identical daughter cells. During mitosis, the genetic material (DNA) is replicated and distributed equally between the two daughter cells. This process is essential for growth, development, and repair in multicellular organisms. Diffusion, filtration, and osmosis are unrelated processes that do not involve cell division.

Explanation
A tissue is not a collection of different cells subject to the same laws of growth and development. Instead, a tissue is a group of similar cells that work together to perform a specific function in the body. Each type of tissue has its own unique characteristics and functions, and they may differ in terms of growth and development. Therefore, the statement is false.

Explanation
The main types of connective tissue are adipose, bone, and fibrous. Adipose tissue is responsible for storing and releasing energy in the form of fat. Bone tissue provides support, protection, and enables movement in the body. Fibrous tissue is strong and provides structural support to organs and tissues. Muscular tissue is not a type of connective tissue, as it is responsible for movement and not for connecting or supporting other tissues.

Explanation
The skin makes up about 7% of total body weight and receives about one third of the fresh blood pumped from the heart. This is because the skin is the largest organ in the body and plays a crucial role in regulating body temperature, protecting against pathogens, and maintaining overall homeostasis. The high blood flow to the skin helps deliver oxygen and nutrients to the cells, remove waste products, and regulate body temperature through the process of vasodilation and vasoconstriction.

Explanation
The statement is true because the skin and hair can provide valuable information about our overall health. Changes in skin color, texture, or appearance can indicate underlying health issues or deficiencies. Similarly, changes in hair quality, thickness, or loss can also be indicative of certain health conditions. Therefore, paying attention to the condition of our skin and hair can help us identify and address potential health concerns.

Explanation
The main part of the sweat gland is not situated in the epidermis. Sweat glands are actually located in the dermis, the layer of skin beneath the epidermis. The sweat gland consists of a coiled tube that extends deep into the dermis, where sweat is produced and then travels up through ducts that pass through the epidermis and onto the surface of the skin. Therefore, the statement that the main part of the sweat gland is situated in the epidermis is false.

Explanation
Hyperkeratosis is a condition characterized by the thickening of the outer layer of the skin, known as the epidermis. It does not necessarily involve deep cracks in the skin, but rather the formation of rough, scaly patches. While hyperkeratosis may take time to heal, it is not specifically described as being slow to heal. Therefore, the statement is false.
