Answer:
Analysis of the data shows that the ratio of floating algae to sea floor algae dramatically increased at the same time that oysters were removed from the Bay. ... (It is also possible to infer from the graph that high floating algae levels led to the decline in oysters.
Answer:
First, let's add the missing piece of information
A school psychologist wants to test the effectiveness of a new method of teaching FrenchFrench. She recruits 100100 firstfirst-grade students and randomly divides them into two groups. Group 1 is taught by means of the new method, while group 2 is taught by traditional methods. The same teacher is assigned to teach both groups. At the end of the year, an achievement test (graded on a scale from 1-10) is administered and the results of the two groups are compared.
The CORRECT ANSWER IS A.
A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.
Explanation:
A control group
The control group acts as a baseline treatment that is employed in contrasting it to the other form(s) of treatments.
Ex: In this case study, a school psychologist wants to test the effectiveness of a new method of teaching French, to see if the ones taught by using a new method (are placed in group 1) do better in learning French than those taught with the traditional method (are placed in group 2). The students being taught French with the traditional method (group 2) would serve as the control group (as this is the present, proven and acceptable practice of teaching French. The factor is the method of teaching French. There are two treatments: new method and traditional method.
Therefore, the option A. is THE CORRECT ANSWER
A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.
Alright, from what you're telling me. (And trust me, I love neuroscience).
This patient most likely has a lesion/damage to his Brocha's or Wernicke's area. A neurological examination will have to be conducted in order to determine which one, test his language comprehension in order to rule out Wernicke's. If you're looking for a more general diagnosis, I'd roughly call it the Temporal lobe.
Active transport is the movement of molecules or ions against a concentration gradient. Passive transport is the movement of molecules or ions from an area of higher to lower concentration.
Passive transport does NOT require energy
-Diffusion - small uncharged molecules
-Osmosis - water
-Facilitated diffusion - glucose
Active transport REQUIRES energy
-Ion pumps
-Endocytosis
-Exocytosis
Type A blood receive A or O. A and O are antigen. Blood type O can give blood to everyone, but A can only give to A blood type.
