Answer:
Ground substance:
Ground substance may be defined as the component of extracellular matrix that made up of proteoglycans. The main function of ground substance is to resist the compressive forces.
Collagen fiber:
Collagen fiber may be defined as a type of protein fiber that provides strength to the organism. Collagen fibers are present within the matrix of the cell.
Elastic fiber:
Elastic fiber are presnt in bundles in the extracellular matrix. The amorphous elastin is present in the elastic fiber. This fiber provide elasticity to the cells.
Reticular fiber:
Reticular fiber composed of the type III collagen. The reticular fiber acts as the supportive mesh of the liver and bone marrow. Reticular fiber was discovered by M. Siegfried.

Explanation:
Lymphocytes are the type of the white blood cell which function as a part of immune system.
Types of Lymphocytes:
T cells
T cells are developed in thymus gland. The specialized molecule of T-cell receptor is located on surface of cell. The molecule is important in the immunity as it recognizes the antigens and thus it to bind to them.
B cells
B cells are important part of immune system. They mature in bone marrow of the humans, and in bursa organ of the birds. The cells have a protein on the surface which is known as B-cell receptor. The protein recognizes and attaches to the specific antigens.
Natural killer cells
Natural killer cells are the lymphocytes which are known to be cytotoxic. They have ability to kill the other cells in the body. The cells are important part of immune system because these cells are able to recognize infected cells.
Answer:
Balcetis explains that when people are in shape, they are more likely to view an exercise as achievable. More important than fitness, however, was individuals’ motivation to exercise. Those who were motivated to exercise saw a finish line as closer, than those who were unmotivated.
In a second study, Balcetis experimented with how changing one’s perspective on an exercise, can help to make it seem more doable. Balcetis presented a finish line at the end of a moderate sized path. Her control group looked around their settings as they normally would, and then estimated how far away the finish line was. The experimental group was instructed to look directly at the finish line and to try to eliminate other objects in their point of view. The results: the group that kept their eyes on the prize estimated the finish line to be thirty percent closer than those in the control group.
Last, Balcetis examined how perspective can help directly improve ease and efficiency. She had subjects try a moderately difficult exercise of walking a fair distance with weights. Again, one group kept their eyes on the finish line, while the other group proceeded normally. Those who focused on the finish line, felt that the exercise was fifteen percent easier than those in the control group. The focused group also moved twenty-three percent faster.
So what do all these findings mean? The way we look at exercise can make a big difference in how hard it feels and how hard we work at it. As Balcetis says, “keeping your eyes on the prize, may be an additional strategy you can use to promote a healthy lifestyle.” Well any strategy that makes exercise seem easier and gets me working harder, is one I’m definitely down for.
