Answer:
A control variable is the variable in the experiment that does not change.
Explanation:
If you are testing how seeds grow in different types of water, and you add 1tbps of salt to one pot of water with the plant, and then added 2tbps to another pot of water with the plant. The control variable in this experiment would be the water with no salt because it was not altered.
FYI I did not pull from google. Good luck!
Answer: b. The radius forms the point of the elbow
c. The radius articulates to the wrist closest to the thumb
Explanation:
Ulna and radius are the two bones of the forearm. These bones articulates with the humerus and carpels of the hand.
b. The radius forms the point of the elbow: The elbow joint is the hinge joint that forms between the proximal ends of the radius and ulna in the forearm and distal ends of the humerus. The radius forms a pointed end.
c. The radius articulates to the wrist closest to the thumb: The wrist forms a complex joint. It forms a transition between the hand and the forearm. The radial deviation in the wrist forms the basis for the movement of the tilting of the wrist joint towards the thumb.
Answer:
The correct answer is: peptidoglycan cell walls and small ribosomes.
Explanation:
Antibiotics such as penicillin are great at attacking bacteria and must be used when dealing with bacterial infections.
Antibiotics work by messing with the bacteria cell wall. The bacteria cell wall is made from peptidoglycan and the strength and support given by it is key to the survival of these prokaryotes. <u>To attack the bacteria, the antibiotics inhibit the assembly of peptidoglycan.</u>
