Blood vessels expand during hot weather and retract/ tighten in cold weather
Explanation:
Generally, a small difference in blood pressure readings between arms isn't a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem
.A significant difference in the pressure recorded in the right and left arms can signal circulatory problems that may lead to stroke, peripheral artery disease, or other cardiovascular problems.
Answer: average popular size in a particular habitat. The species population size is limited by environmental factors like adequate food,shelter,water,and mates
Explanation:
ABI means Ankle-Brachial Index. ABI is a test used to diagnose peripheral artery
disease. The ABI compares
blood pressure in the ankle to blood pressure in the arm, shows how well blood is flowing in the
limbs and indicates if there is any or no blockage or rigid arteries. The amount of blockage establishes
the level of peripheral artery disease.
Answer:
The correct answer is ''carbon dioxide, water vapor and nitrogen.''
Explanation:
About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.
