Answer:
Claim: A tissue is made up of many similar cells that are connected and organised.
Evidence: In cardiac muscle tissue, group of cardiomyocytes are joined in the same direction.
Claim: Cells in a tissue work together to allow the tissue to carry out its function.
Evidence: In cardiac muscle tissue, group of cardiomyocytes expand and contract at the same time.
Explanation:
Cells are the building blocks of life, and a group of specialized cells form a tissue, which has a specific function.
In human heart, the cardiac muscle tissue is a specialized type of striated muscle tissue formed from cardiomyocytes. Their fibers are branched, have a single nucleus and are joined together by intercalated discs. This tissue contracts and releases involuntarily and helps the heart to pump blood throughout the body. Cardiac muscle cells (cardiomyocytes) are the muscle cells which form the cardiac muscle tissue. They are responsible for the rhythmic beating of the heart by expanding and contracting at the same time.
Answer:
As you know that blood is composed of two parts:
1. Blood cells, and
2. Blood plasma.
Blood cell is the solid part of blood contain different types of blood cells such as RBCs, WBCs and platelets. Blood plasma is the liquid portion of the blood. So if blood cells are removed the remaining part is solely consisting of blood plasma.
The study of life is called Biology
