Austin and Marissa hypothesize that coneflower stomata use feedback loops to respond to moisture levels by opening when there is moisture present, and closing when there is no moisture present. Which BEST describes the setup they should use to support their hypothesis? A
Austin and Marissa should observe the number of closed stomata on one leaf, mist the leaf with water, wait one hour, and count the total number of stomata.

B
Austin and Marissa should observe the number of stomata on one leaf, mist the leaf with water, wait one hour, and count the number of stomata that have grown.

C
Austin and Marissa should observe the number of open stomata on one leaf, mist the leaf with water, wait one hour, and count the number of open stomata again.

D
Austin and Marissa should observe the number of stomata on one leaf, mist the leaf with water, wait one hour, and count the number of stomata that have disappeared.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
