Answer:
c) Yes, because subjects in both experimental groups has slower reaction times than subjects in the control group.
Although Dr. Fitz's experiment is correct, he could improve it by placing men and women in the experimental and control groups.
Explanation:
The control group in an experiment, is the group that does not receive the treatment that is being tested in that study. Therefore, this group must present different results from the experimental groups that received the treatment that is being tested.
In the experiment shown above, the control group is formed by the ladies who did not receive any dose of alcohol and therefore had a faster reaction time than the individuals who formed the experimental groups (who received alcoholic drinks)
To make the experiment more accurate, Dr. Fitz should have formed all groups with men and women, since he could show whether the effect of alcohol is the same or different in relation to gender.
Answer:
variables that help to increased the rate of diffusion are
1) concentration of glucose
2) by increasing the number of membrane carriers
Explanation:
variables that help to increased the rate of diffusion are
1) concentration of glucose - the rate of diffusion increased when molecules concentration outside the cell is more than internal concentration. It is all part of the concentration gradient. Higher the concentration gradient higher will be the rate of diffusion
2) by increasing the number of membrane carriers - the rate of diffusion increased by increasing concentration of solute in the cell which is increase by carrier proteins.
Answer:
Catastrophism
Explanation:
Catastrophism is the view that Earth has been shaped by a series of random, violent, global-scale events such as meteorite impacts, fast-paced climate change, collisions with other celestial bodies, and large-scale volcanic activity.
Examples of catasrophism are the hypothesis that the moon was formed after the Earth collided with another planet of the size of mars, and the hypothesis that dinosaurs went extinct after the impact of an asteroid in the Gulf of Mexico and the Yucatan Peninsula.
