Answer:
Depends on what you are changing.
Explanation:
Protons have a positive (+) charge.
Neutrons have a neutral (0) charge.
Electrons have a negative (-) charge.
Since neutrons only affect atomic mass, we don't need to worry about it changing the charge.
If we had more protons than electrons, then since there are more + charges, the entire atom would be positively charged.
If we had more electrons than protons, then since there are more - charges, the entire atom would be negatively charged.
Answer:
a. the blood pressure decreases. the bblood in the A that is the artery is higher as the artery carries the oxygenated blood which is directly pumped out of the heart.so the artery's pressure is higher where as the capillaries pressure decreases when compared with artery. the blood in the capillary flows slowly and smoothly as capillary needs time to exchange the substance between the body cells and the blood. the vein carry the deoxygenated blood back to the heart so their pressure is low.
b.the highest pressure is found in the artery because it carries the oxygenated blood and the heart pump the blood with great force thus tge artery have the highest pressure . and it also wanted to transport the oxygen quickly to other parts of the body.
c. valves. these prevent the backflow of the blood in capillary as the blood moves against the gravity.so valves prevent the blood from going back . therefore the valves help the blood in veins to move back to heart. (not sure)

Answer:
C. The high-tide zone is outside the range of tolerance for Semibalanus.
Explanation:
Semibalanus can out-compete Chthamalus by crowding or smothering, but Chthamalus can occupy higher tide levels than Semibalanus because it is more resistant to desiccation.
The fundamental niche of Chthamalus includes both the upper and middle intertidal zones. - The realized niche of a species is a subset of the fundamental niche, limited by biotic interactions such as competition. The realized niche of Chthamalus is the upper intertidal zone only.
