Most of the exchange surfaces of multicellular animals are lined with epithelial tissue.
Epithelial tissue is one of the four major body tissues found in organs, lining the internal and external surfaces of the body.
It has different structures and functions depending on where it is located on the body.
The epithelium is a type of body tissue that covers all the internal and external surfaces of the body, lines body cavities and hollow organs.
Epithelial tissue has various functions, such as protection, secretion, and absorption, depending on where it is located in the body. The body organs are made up of four basic types of tissue, including:
- Epithelial tissue
- Connective tissue
- Muscular tissue
- Nervous tissue
All substances entering or leaving an organ must first pass through the epithelium.
There are various types of epithelial tissue throughout the body. Some examples of epithelial tissues are:
- The outer layer of skin (epidermis).
- Intestinal mucosa.
- Airway lining.
- Inner wall of abdominal cavity.
- Sweat glands

Answer:
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food. The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
Explanation:
Answer:
The correct answer will be
1. Inversion
2. 20-25 minutes
Explanation:
The injuries of the ligaments of the ankle are common among athletes like the anterior tibiofibular ligament sprain (AFTL) or calcaneofibular ligament (CFL) which are caused by the inversion of the flexed foot.
These cases of ankle sprains are treated with the rest and applying ice to the injured area for approximately 20-25 minutes repeated for 3-4 times per day.
Thus, Inversion and 20-25 minutes are the correct answer.
Answer: DNA was the first genetic material.
Explanation:
The genetic code is essentially the same in all the organism. This states that the similar organism can have similar genes in them that codes for the similar proteins hence, called as similar organism.
The genetic material is chemically made of nucleotide which is either being synthesized in the body or being obtained from the environment similar to that of amino acids.
If the genetic code is same one organism descend from the other organism.But these statement does not supports that DNA was the first genetic material to found in living beings.
