Answer: D) much slower
Explanation:
The circulatory system, made up of arteries and veins, is fundamental to maintaining life. Its function is the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of physiological pH, and the mobility of the elements, proteins, and cells of the immune system. An artery is each of the vessels that carry blood with oxygen from the heart to the capillaries of the body. They arise from a ventricle and their walls are very strong and elastic to resist the pressure that the blood exerts when it is pumped out of the heart.
Capillaries are very small diameter, thin-walled blood vessels connect small arteries (arterioles) to veins, allowing nutrients and oxygen to pass through to tissues. The main function of the capillaries is the exchange of substances between the light of the capillaries and the cell interstice of the tissues.
When the blood reaches the capillary bed, the speed with which it circulates inside these vessels is very low. This is due to the fact that in a branching system of tubes, the speed decreases proportionally to the increase in the joint section of the branches. Thus, in the aorta, which has a small section, the speed is very high (400 mm/sec), it decreases at the level of the arteries and arterioles and at the capillary level it becomes minimal (0.1 mm/sec). <u>This fact, together with the thinness of the capillary wall, provides the necessary conditions of time and space for the exchange to take place in the most optimal way.</u>

Answer:
Proteins can be catalysts which help to reduce the energy used in a chemical reaction or speed it up. Proteins can help carry oxygen throughout the body in the form of hemoglobin
Explanation:
Sponge body contains cells but not perform work together!!
But they are made up of two embroyonal layer as endoderm and ectoderm !!
so thee most appropriate answer is A !!
Yes like friction or gravity it all has some kind of scientific explanation behind it For example y*x/v[lmn +the number of atoms in the mind and all this is its the way checkers is played its amazing
In this case, the plot 1 is very rich in the single species; it is dominated by a particular species, which occupy 95% share. While in the plot 2 are rich in the number of species, it has 5 species occupying 20% share.
In comparative analysis, it is seen the plot 1 is rich in species, but diversity is very less. While, plot 2 is rich in the diversity of species, as 5 different species are present, but it is not rich in a particular species.
Hence, compared with plot 1, plot 2 has greater species diversity and lower species richness.
