Answer Key

#	Answer
1	One major challenge is the lack of gravity, which affects movement, fluids, and body functions.
2	Microgravity means a condition where gravity is very weak or feels nearly absent.
3	The skeletal system is especially affected.
4	They need exercise to help reduce muscle loss and bone loss in microgravity.
5	The body may lose muscle mass, bone density, or balance ability.
6	Plants can help provide food and produce oxygen.
7	Fluids shift upward in the body, which can cause facial puffiness and other changes.
8	On Earth, gravity helps guide root and shoot growth, while in space that guidance is reduced or altered.
9	Scientists study bacteria in space to see how space conditions affect growth, mutation, and survival.
10	Radiation is energy from sources such as the Sun and cosmic rays that can damage cells.
11	Earth’s atmosphere and magnetic field provide protection that is much weaker or absent in space.
12	Space conditions may weaken immune responses or change how the immune system functions.
13	They need proper nutrition to support health, energy, and body maintenance in a difficult environment.
14	They are useful because they have shorter life cycles and can help scientists study biological effects more quickly.
15	It is trying to learn how space conditions change cell growth, structure, or function.
16	Long-term space travel may affect reproductive cells, development, or fertility, so it must be studied carefully.
17	It helps scientists design better exercise plans and protect astronauts from muscle weakening.
18	Controlled environments can manage light, water, temperature, and nutrients to help plants grow successfully.
19	It can improve medicine, agriculture, and our understanding of how living things adapt to stress.
20	Long-duration missions require careful planning because space conditions can affect bones, muscles, immunity, nutrition, and overall health over time.
