The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.
Option A
<u>Explanation:</u>
According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.
In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.
So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.
Answer:Carbon dioxide accounts for most of the nation's emissions and most of the increase since 1990. Transportation is the largest source of greenhouse gas emissions in the United States, followed by electricity generation.
Explanation:
Answer:

If a urine sample is collected without cleansing adequately under foreskin, this ample may contain this bacteria in the sample. One should clean the beneath the foreskin properly to prevent the sample to get voided.
Answer:
"Yes" The streak plate method is very effective in diluting the population size in all 4 plates.
Explanation:
The streak plate method is effective because it is one among the rapid isolation method which further allows for easy observation of the bacteria. This method is also being used for getting the color of the certain substances. Its main principle is to isolate the specific bacteria from the sample of various microbes. It dilutes the microbes number and often reduces their density. It is useful in separation of organisms from the group. These are isolated in the agar plate.
Mrs. Lopez has the most difficulty initiating digestion of proteins after her stomach is removed. The correct option is C.
Explanation:
When the stomach is removed due to complications such as in cancers the food eaten directly goes to intestine. Without stomach Mrs Lopez will have difficulty in starting the digestion of protein.
The digestion of protein takes place and starts in the stomach and duodenum of intestine. There are enzymes as pepsin, trypsin and chyomtrypsin secreted by stomach and pancreas. Pepsin breaks the peptide bonds of protein.
The HCl and the enzymes in stomach initiates the process of digestion of protein. The amino acids formed are ardent in various metabolic processes and repair.
lipids and carbohydrate digestion starts from the mouth only as salivary amylase and lipase initiates the process.
