Which statement describes the Mercalli scale?
1 This scale measures seismic waves based on their size.
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.
Answer:
2- this scale rates an earthquake according to how much damage it causes
Mercalli scale rates an earthquake according to how much damage it causes. So, the correct option is B.
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.

Glycolysis
Explanation:
Glycolysis is the first step in cellular respiration, both aerobic and anaerobic.
Glycolysis occurs in the cytoplasm, whereas other steps of aerobic respiration occur in the mitochondria.

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.Learn more here:
