Question

How did NASA help to distinguish genetic factors from environmental ones when studying the effects of living space? 1) By observing changes in retired astronauts over a period of ten years. 2) By running experiments on astronauts that were in space for over a year. 3) By analyzing changes in one twin on Earth and the other in space. 4) By introducing animals and other organisms that could be studied in space.

Answer 1

NASA used different methods to distinguish genetic factors from environmental factors when studying the effects of living space on astronauts.

Step-by-step explanation:

NASA used a variety of techniques to assist in separating hereditary and environmental components when researching the impacts of living in space. The following steps were involved:

• By observing changes in retired astronauts over a period of ten years.
• By running experiments on astronauts that were in space for over a year.
• By analyzing changes in one twin on Earth and the other in space.

These approaches allowed NASA to compare the effects of genetics and environment on the astronauts' health and well-being.
