Answer:
D
Explanation:
The vehicles have the same amount of kinetic energy because they are travelling at the same speed. There is a great difference in their masses but their speed is same. Kinetic energy of a body depends on both mass and velocity. If the mass of an object increases, its kinetic energy also increases and vice versa while on the other hand, if we doubles the speed of an object its kinetic energy increases four times so we can conclude that objects having same speed leads to same kinetic energy.
Answer:
The answer is C
Explanation:
All living things are made up of cells!
Well, in terms of the science of artificial selection, mutations will be useful in achieving your goal as a genetic mutation that happens often in insects, particularly fruit flies, is a change of color. A strategy that could be used would be a Punnet square to simulate the possible crosses between the insects and which is most likely to bring out the recessive gene (the desired color). Finally, the breeding of dogs can be explained by humans breeding tall dogs with other tall dogs to ensure that the outcome would most likely be another recessive gene (tallness) and a similar set of events would explain the Pomeranian (short dogs being breed with other short dogs) <span />
Answer: Mitochondria
Explanation:
Mitochondria are rod-shaped organelles bounded by a double membrane in which the inner membrane is folded and filled with matrix. Mitochondria is present in both plant and animal cells, and serves as the power house where respiration occur and energy is released from the oxidation of simple sugar.
<span>removal of a keystone species makes the rest of the system more unstable, but the best way to understand how this works is to visualize it, either by drawing a model, or using a diagram.

Atlantic Cod is a keystone species. if the cod were removed, the seal population would decline because of a prey shortage, which would increase the populations of all the other fish species that the seals consume. Those increased fish populations would then overexploit their available prey, causing the population of prey to decline, resulting in a decline in predatory fish, resulting in an increased decline in the seal population, etc.
In addition, each increase or decrease in any species will affect every other species it interacts with, creating one hell of an unpredictable mess, which often leads to ecosystem collapse and/or extinction.
This phenomenon is known as trophic cascade.
