In a vacuum, the gravitational force is "turned off." (2 points)Select one:
True
False

Answers

Answer 1
Answer:

The given statement is false.  

• In a vacuum, when an object falls it is subjected to only one kind of force, that is, the gravitational force, which is considered as the object's weight.  

• In a vacuum, all the objects fall at the same rate due to gravitational force. In a vacuum, the mass of the object does not matter.  

• In a vacuum, the moving of the object only takes place due to gravity is considered to be free-falling, and its motion is illustrated by Newton's second law of motion.  

Thus, gravitational force does exist in a vacuum.

Answer 2
Answer:

Answer: False

Explanation: Because, A vacuum has no particles of gas in it, but there is still gravity it just has nothing to act upon.

Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.What does this information best demonstrate?

Answers

Insulin is one of the significant hormones in the human body. The information about insulin and its mechanisms explains how the human body uses food for its energy requirements.

Generally, glucose obtained from the food that travels in the bloodstream is responsible for elevating the blood sugar level. The pancreas is an organ that helps in releasing insulin for controlling the blood glucose level. Insulin tends to get released in a feedback mechanism depending on the blood sugar level.

The mechanism of insulin best demonstrates the following:

  • Insulin along with glucagon helps in maintaining the state called homeostasis for the steady condition in the human body
  • Insulin is considered vital for cells to utilize glucose and obtain energy

Thus, the mechanism of insulin in the human body explains how energy is utilized by different cells and how insulin is important in maintaining homeostasis.
