Answer – B. (Return blood to the lungs)
The function that capillaries serve in the cardiovascular system is to return blood to the lungs. The capillaries beds are the area where the excess carbondioxide produced by the cells are exchanged with oxygen. The deoxygenated blood is then transported by the capillaries through the circulatory system back to the lungs for reoxygenation

Answer:
iv. There is no force of gravity acting upon orbiting astronauts.
2. it measures the mass
Explanation:
A logical fallacy occur in step iv
There is actually force of gravity upon the orbiting astronauts. Gravity exist in space. there is an upward and downward forces that keeps the body stable.
1,ii,iii are correct logical statements
2.What does the scale measure? ___________________ If a scale does not technically measure your weight, then why is it often used to measure your weight?
The scale measures ones mass.
Mass is the quantity of matter in a body. Matter is anything that has weight and occupies space. Assuming we are to measure the weight of ones body we will need to be hanged in the air and take measurement with the aid of a spring balance.
At this instant, the force of gravity will be acting on the body(that is one will experience the earth's gravitational pull to the earth's center)
Force is the pull or push on an object. F=mass * gravity
Force is also that which tends to change a body's state of rest or uniform motion on a straight line.
Newton's second law of motion states that the force applied is directly proportional to the rate of change in linear momentum
The answer is the first one, A!

Answer:
True
Explanation:
The metabolism refers to the process taking place in humans which provide energy for living. The metabolism of people may differ from person to person that is some people will have high metabolism whereas some people will have a slow metabolism. This difference in metabolism is genetic and is inherited.
But the metabolism can be temporarily shifted to high to slow and slow to high through the exercise and physical activity. If we exercise daily, then the consumption of the energy automatically increases thus the slow metabolism shifts to high metabolism.
Thus, true is correct.
