Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
I think it is False. Heterotrophs are organisms that cannot make their own food. They obtain it from consuming other organisms. To make this statement true, you would have to replace the word, "heterotoph" with the word "phototroph" or "autotrophs".
I would need to see what is labeled b, in order to help you.
Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
The answer is bradycardia.
Beckham has a low blood pressure (hypotension) and low heart rate(bradycardia). It shows that the heart is not strong enough to pump blood as usual. This could be the result of the heart attack, which make most of the heart muscle can't work. This condition also could be called as acute heart failure.
