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 vaccine is needed especially for those who are of greater risk to have a flu, including pregnant women, children, and persons with serious medical conditions.

Explanation:
Dynamic aspects of an ecosystem are mineral cycles and energy flow. Mineral cycles are biogeochemical cycles through which there is exchange or circulation of nutrients in the biosphere. Energy flow occurs in a unidirectional manner in an ecosystem from lower trophic levels to higher trophic levels. Through these dynamic aspects, biotic and abiotic components of an ecosystem are connected. Biotic components are living part of the environment which include producers, consumers and decomposers whereas abiotic components are non living part of the environment which include light, water, temperature etc.
