When a person gets dehydrated while exercising on a hot day, their pituitary gland releases ADH, a hormone that signals the kidneys to retain more water. This is an example of Positive feedback regulation Negative feedback regulation Chemical cycling Emergent properties Which of the following types of cells utilize deoayribonucleic acid (DNA) as their genetic material but do not have their DNA encased within a nuclear envelope achaean fungi A localized group of organisms that belong to the same species is called community population ecosystem family You find yourself standing next to a beautiful rose bush Which of the following do you and they have in common You both are multicellular. You both lack a membrane-bound nucleus. You are both prokaryotic. You and the rose have nothing in common. The best experimental design includes a large sample size for each condition includes a control alters only one condition between the controls and the experimental condition includes a large sample size and a control, and alters only one condition between the controls and the experimental condition A controlled experiment is repeated many times to ensure that the results are accurate includes at least two groups, one of which does not receive the experimental treatment includes at least two groups, one differing from the other by two or more variables includes one group for which the scientist controls al variables Which of the following represents the correct sequence of levels in life\'s hierarchy, proceeding downward from an individual animal? brain, spinal cord, organ system, nerve cell, nervous tissue: b) organ system, population of cells, nervous tissue; organism, cardiovascular system, cardiac tissue, myocardial cell organism, intestinal cells, digestive system, pancreas, Which of the following statements characterizes a prokaryotic cell The presence of mitochondria. The lack of a membrane-endorsed nucleus. d Having a cell wall without a cell membrane. The ability of water molecules to form hydrogen bonds with other water molecules is critical to: evaporative cooling of the skin surface the movement of water from the roots of a tree to its leaves. The milder temperature of coastal regions when compared to inland areas the ability of certain insects to walk on the surface of water; all of the above. Which of these provides evidence of the common ancestry of all life? near universality of the genetic code structure of the nucleus structure of cilia structure of chloroplasts
1. The answer is option b that is negative feedback regulation.
2. The answer is option c that is Archean.
3. The answer is option b that is population.
4. The answer is option a that is you both are multicellular.
5. The answer is option d that is it includes a large sample size and a control and alters only one condition between the controls and experimental condition.
6. The answer is option b that is it includes at least two groups, one of which does not receive the experimental treatment.
7. The answer is option c that is an organism, cardiovascular system, cardiac tissue, myocardial cell because it shows the correct level of organism buildup.
8. The answer is option b that is the lack of membrane-bound nucleus because the prokaryotic cells lack the nucleus and have a free-floating genetic material.
9. The answer is option e that is all are important because the hydrogen bonding of water molecule with each other allows the evaporative cooling of the skin. it also allows the movement of water in xylem in plants and the cohesion allows the high surface tension fro the movement of insects on the surface of the water.
10. The answer is option a that is the near universality of the genetic code.
