Answer:
The slow rate at which diffusion occurs over large distances.
Explanation:
Circulatory system may be defined as one of the most important system of the body that contains arteries and veins. Two main types of circulatory system are open circulatory system and closed circulatory system.
The blood flow all over the body to each cell with the help of the circulatory system. Arteries carry oxygenated blood and veins carry deoxygenated blood in the body. The circulatory system increases the rate of blood flow as diffusion do not allow the transport at long distances.
Thus, the correct answer is option (c).
By speed sonic wins by far
It’s B. I did research and found that it’s the application of scientific knowledge for practical purposes.
The terrestrial gastropods are the only mollusks that have adapted to all the habitats of the Earth. They dwell in areas of high altitude, mountainous regions, hot and cold places. Land snails live and perform their vital functions on the ground and not in the sea or bodies of fresh water.
Answer:
A homologous pair
Explanation:
In determining the expression trait of humans, this is based on the homologous chromosomes. This in turn comprised of alleles otherwise known as homologous alleles. The homologous loci are thereby located in these alleles which served as the formation of traits when combined.
Hence, normally, A HOMOLOGOUS PAIR is required to determine the outward expression of a trait?
