Answer:
B) 5m/s^2
Explanation:
The formula for acceleration is 
vf is the final velocity which in this question is 25m/s
vi is the initial velocity which in this question in 0m/s because it says "A <u>stopped</u> car"
t is the time which is 5 seconds
When you put these numbers into the formula you get 5m/s^2
Answer:
In the chloroplast.
Explanation:
Chlorophyll is a green pigment plants use to absorb light so they can make food via photosynthesis. Chloroplasts are organelles that contain chlorophyll, so it only makes sense that the best answer is the chloroplast.
Answer;
Amino acid side chains have many carboxyl and amino groups.
Explanation;
-A buffer solution is a solution that resists changes in pH when small quantities of an acid or an alkali are added to it. It is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.
-Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis.Small molecules such as bicarbonate and phosphate provide buffering capacity as do other substances, such as hemoglobin and other proteins.
-
Protein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. Since amino acids have the capability of reacting with both acid and base, they naturally act as buffers.
Answer:
In Pavlov's study, the unconditioned stimulus (UCS) was __Meat_; the neutral stimulus was ___bell__; and, finally, the conditioned stimulus (CS) was __bell__.
Explanation:
Pavlov was a physiologist and was studying the digestive system but he came up with the most valuable studies of psychology. He put the tubes in dog mouth to collect saliva and calculate the amount of saliva produced by dog in response to different stimuli.
- He provided the meat to dog and dog produced saliva in response to unconditioned stimulus of meat. It was the natural reflex.
- He ring the bell but there was no saliva produced by dog in response to the bell. This was called as neutral stimulus.
- Then he associated the ringing of bell just before providing the meat (unconditioned stimulus). After several time the dog started to produce saliva on ringing of bell which was conditioned stimulus (CS).
