Q5.

The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.

The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to

posledela

Answer:

The correct answer will be option-E

Explanation:

Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.

To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.

In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.

Thus, option-E is the correct answer.

Given the inefficiency of two of the pathways shown in Figure 2-4, what advantage could

grandymaker [24]

I’m assuming this entire thing is cellular respiration. pathway a most likely represents alcoholic fermentation, B represent lactic acidosis fermentation, C probably represents aerobic cellular respiration. Alcoholic fermentation doesn’t occur in humans, it occurs in micro bacteria and yeast. Lactic acidosis fermentation occurs in humans when there is not oxygen. That’s why you breathe so heavily after sprinting. Cellular respiration just happens naturally. Idk if that’s what the question is asking so feel free to comment and if this helped, brain answer?
