Answer:
The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body. Blood plasma also carries all parts of the blood through your circulatory system.
Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. ... Bedrock is consolidated rock, meaning it is solid and tightly bound. Overlying material is often unconsolidated rock, which is made up of loose particles
Clayey soil is rich in organic matter. It provides essential compounds and minerals to the crops so that they can grow better. - For growing crops such as wheat, gram, and paddy, the soil that is good at retaining water and rich in organic matter is suitable.
Spirogyra species can reproduce both sexually and asexually. Asexual, or vegetative, reproduction occurs by simple fragmentation of the filaments. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

Arteries experience a pressure wave as blood is pumped from the heart. This can be felt as a "pulse." Because of this pressure the walls of arteries are much thicker than those of veins. ... The vessel walls of veins are thinner than arteries and do not have as much tunica media.
Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).
