How did NASA help to distinguish genetic factors from environmental ones when studying the effects of living space?.
NASA help to distinguish genetic factors from environmental ones by
analyzing changes experienced in one twin on Earth and the other in space.
NASA planned to study how environmental conditions affects the health
conditions of humans. They decided to use twin brothers because of them
sharing the same genetic makeup.
One of them is taken to space and the other is left on earth and their health
are studied to ascertain any change as a result of the environmental change
to that of space.

Changes in water pressure within guard cells cause the cells to open or close the stomata. This response helps the plant maintain homeostasis by
Answer:
reduced water loss
Explanation:
When the water enters the cells, they swell and become bowed. This causes the guard cells to bend away from each other, thereby opening the stomata. Conversely, when guard cells lose potassium ions, water diffuses out of the cells by osmosis.
The response helps the plant maintain homeostasis by regulating water levels that plants lose during transpiration.
What is cellular homeostasis?The expression cellular homeostasis makes reference to the processes by which an organism maintains an internal state of equilibrium.
Cellular homeostasis is fundamental for the survival of the cell and the organism.Cellular homeostasis in this case indicates the mechanism to maintain concentration and gradients used by the plant to carry out metabolic functions.In conclusion, the response helps the plant maintain homeostasis by regulating water levels that plants lose during transpiration.

which test measures the flexibility of the lower back and hamstrings
Answer:
The Sit and Reach Test
Explanation:
The Sit and Reach Test is one of the linear flexibility tests which helps to measure the extensibility of the hamstrings and lower back. It was initially described by Wells and Dillon in 1952 and is probably the most used flexibility test.
