The correct answer is A. Variation.
The key word in the text is "different." There is a variety of horn sizes among horned animals.
Eliminated Answer Choices:
The answer cannot be B. Overproduction because the text does not give any information about reproducing or populations.
The answer cannot be C. Survival of fit individuals because survival of the fit is related to adaptations and the text does not mention anything about that.
Hope this helps. Good luck! :)
Yes, because you do not know if the squirrel like peanuts, so you will need to experiment✨
Answer:
All energy in the system are either potential or kinetic.
Option A to D are true
Explanation:
Kinetic Energy is the energy in a body when the body is not at rest (i.e. when it is in motion)
Whole
The potential energy of an object is energy of the body in a stored form. This means that when the body is at rest (not moving but waiting to do work). This is seen in Option A where the ball is held motionless above the floor.
The potential energy of a body decreases when the body moves downward and the kinetic energy increases. This is seen in Option B and C.
The last option D is supported by the first law of thermodynamics, also known as Law of Conservation of Energy, which states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. The potential e ergy of the body when held motionless above the floor is equal to the kinetic energy of the body when it hits the floor.
Answer:
A. 
B. 
C. 
D. 
Explanation:
Hello.
In this case, we must compute the final concentration in all the cases so we solve for it in the given equation:
Thus, we proceed as follows:
A. Here, the final diluted solution includes the 300 μL of the 5 mg/ml-BSA and the 700 μL of TBS.
B. Here, the final diluted solution includes the 50 μL of the 1.5 mg/ml-BSA, the 450 μL of water and the 500 μL of TBS.
C. Here, the final diluted solution includes the 10 μL of the 1 mg/ml-BSA and the 990 μL of TBS.
D. Here, the final diluted solution includes the 10 μL of the 0.1 mg/ml-BSA and the 990 μL of TBS.
Best regards.
