a. Epithelial tissue
b. Muscular tissue
C.Connective tissue
d. Nervous tissue

(1) a and b only
(3) a and c only
(2) b, c, d only
(4) a, b, c and d​

Answer 1

(1) a and b only. Organs such as lung and stomach show presence of

Epithelial tissue and Muscular tissue.

• An uninterrupted layer of closely packed cells forms epithelial tissue.
• The epithelium tissue has one surface that is either open to the environment outside or to bodily fluids.
• The membrane that connects the other surface to the tissue is made up of fibres and polysaccharides that are secreted by epithelial cells.
• There isn't much intercellular substance between cells.
• The epithelium's cells are connected by specialised junctions that join individual cells together.
• Soft tissues called muscle tissues are what most animals' many types of muscles are made of and what allows muscles to contract.
• Additionally, it is known as mypropulsive tissue. The process of myogenesis, which forms muscle tissue throughout embryonic development, is known.
• Actin and myosin, two unique contractile proteins found in muscle tissue, contract and relax to produce movement.

Answer 2

Answer:

Organs such as lung and stomach show presence of

Epithelial tissue and Muscular tissue.

Explanation:

• What is epithelial tissue? It is the type of body tissue which forms the covering on all internal and external surfaces of our body, lines body cavities and hollow organs. Epithelial cells are held together by tight junctions. There are four types of epithelial tissue. 1. simple squamous 2. simple cuboidal 3. simple columnar 4.pseudostratified.
• What is muscular tissue? Muscle tissue are composed of the cells that have the special ability to shorten or contract in order to produce movement of the body parts. There are four main types of muscle tissue- cardiac, smooth and skeleton. Muscle tissue is characterized by the properties which allow the movement.
• Therefore organs such as lung and stomach show the presence of Epithelial tissue and Muscular tissue.
• Which is option number 1 which is a and b only.

Hence, option 1 is correct answer.
