Answer:
The correct answer is option E.
Explanation:
The effect on the growth of the full sunlight and green light or the increased carbon dioxide and normal air. There are several effects that can affect the growth of the plant can be affected. Provided options are directly or indirectly affects the variables that are unknown but can affect the growth of plants.
Increased in carbon dioxide does not leads to the decrease of other essential gasses in substantial amount, common uniform strain of seedlings are also cause effects the experiment of plant growth in specific manner. Light is also one of influential and limitation factor that affects the growth of the plant.
Thus, the correct answer is is option E.
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:YES
Explanation:A PDA is a type of congenital heart defect. A congenital heart defect is any type of heart problem that's present at birth. If your baby has a PDA but an otherwise normal heart, the PDA may shrink and go away. Some children need treatment to close their PDAs.
Answer:
B
Explanation:
The rate of mutations on the S. Aureus population increased when exposed to antibiotics over time. This gave rise to a few mutants of the bacteria that could survive the methicillin antibiotic. This is because the mutation altered a protein target of methicilin (beta-lactam binding proteins) on which the antibiotic acted upon. These populations increased as the others were eliminated by the antibiotic – the way natural selection works. Over time, these mutations were transferred to other populations of bacteria by these MRSA through ‘sexual’ horizontal gene transfer, causing whole bacteria populations to be resistant against methicilin.
