An ocean scientist plans to spend several days underwater in a submarine. Doctors on land will monitor her body to make sure she is healthy during her trip. What is one way doctors will be able to tell whether her body is healthy enough to do all her tasks while she is in the submarine?
a The doctors could see if her cells are getting several different types of food molecules.
b The doctors could see if she is getting plenty of sleep so her body can make enough energy.
c The doctors could see if her lung cells have molecules from air, and her stomach cells have molecules from food.
d The doctors could see if her cells are getting the molecules they need from food and air.

One way in which doctors will be able to tell whether this ocean scientist's body is healthy enough to do all her tasks while she is in the submarine is that: D. The doctors could see if her cells are getting the molecules they need from food and air.What is cardiorespiratory fitness?Cardiorespiratory fitness can be defined as a measure of the ability of the circulatory and respiratory system to supply oxygen obtained from the air, to the skeletal muscles that are found in the body of a living organism, especially during any sustained physical activity such as an aerobic exercise.Generally speaking, the cardiorespiratory fitness of an individual such as an ocean scientist, is usually measured at rest, especially through a measurement of blood pressure or through the use of an electrocardiogram (ECG or ECK).In conclusion, it is very important for the doctors to determine if this ocean scientist's body cells are well energized by food and air.Read more on cardiorespiratory fitness here: brainly.com/question/956236#SPJ1
