Answer:
it helps the plant to take in sunlight and oxygen.
Answer:
The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.
It is important to maintain the ph of blood and tissue fluids within normal limits because the structure and function of macromolecules are pH sensitive, and even little variations from normal pH can cause metabolic processes to shut down.
Tissue fluid is found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
The two forms of connective tissue in this subcategory are blood and lymph. Both are fluid rather than solid, and neither has the network of extracellular protein fibers that other types of connective tissue have.
Diffusion and filtration processes create tissue fluid from plasma. This fluid fills the intracellular space and serves as a link in the transmission of nourishment, gases, and metabolic end products between blood capillaries, tissue fluid, and lymph.

Answer: G. thymosin and thymopoietin
Explanation:
The thymus produces and secretes thymosin, a hormone necessary for T cell development and production. The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat.
