Answer: A. the gravitational pull of the Sun

The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.

What would happen if complexes I-IV of the electron transport chain pumped protons in the opposite direction?

a. Too much ATP would be synthesized.
b. None of the other answer options is correct.
c. No ATP would be synthesized.
d. There would be too many electrons in the mitochondrial matrix.

Answers

Answer:

The correct answer is - c. No ATP would be synthesized.

Explanation:

In the electron transport chain there are four complexes, complexes I-IV, pumps the protons from the matrix of the mitochondria into the intermembrane space. This is the downhill movement of the electrons that helps in synthesizing the ATP molecules.

If the complexes move or pump the electron uphill or against the gradient there would be no ATP formation as there would be no interchange of proton and electron interchange.

The main features of photosynthesis include:

It takes place in the chloroplasts of plants, in the presence of sunlight.The energy needed for the process is gotten from sunlight which is absorbed by chlorophyll found in the chloroplasts.The raw materials used are low-energy containing inorganic compounds, example: carbon dioxide and water.The final products are high-energy containing sugars. oxygen is given off as a waste product.

2 This scale rates an earthquake according to how much damage it causes.
3 This scale produces a single rating for earthquakes that reach the surface.
4 This scale measures the magnitude of an earthquake based on the size of seismic waves.

Answers

Answer:

2- this scale rates an earthquake according to how much damage it causes

What is Mercalli scale?

The Mercalli scale was invented by Giuseppe Mercalli in 1902, is not regarded as a scientific method for measuring the strength of an earthquake.

The Mercalli scale is used in the observations of people who experienced an earthquake to estimate the intensity, which is measured based on the degree of impact or damage to humans, objects, buildings, and other man-made things.

The scale typically measures the intensity of an earthquake using data such as effects on the Earth, the environment and humans that help predict whether an earthquake was fatal.

Thus, Mercalli scale rates an earthquake according to how much damage it causes. So, the correct option is B.
