Answer:
1) Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
2)Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other.
3)lymph drains from small pores in capillaries to intracellular spaces . It is white as it is devoid of RBC's.
4)The xylem consists of tracheary elements, xylem parenchyma cells, and xylem fiber cells. Tracheary elements are dead, hollow cells with patterned cell walls comprising xylem vessels and tracheids, which function as conductive hollow tubes for water and nutrient transport throughout the plant body.
5)Meristematic tissues contain living cells with varied shapes. They possess a large nucleus devoid of the vacuole. The cells have no intercellular space. ... The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc.
6)vascular bundles consisting of both phloem and xylem ensure connection between tumors and the rest of the host plant, thus enhancing water and solute transport.
7)Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process. Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions.
8)Movement or the passage of food in the intestine is caused by the contractions of the smooth or unstriated muscle tissue.

Hope it helps:-
Step-by-step explanation:
If n is a perfect square then √n is a an integer and therefore rational, so it suffices to prove that if n is not a perfect square, then √n is irrational.
