A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years. And if the star is very small, with a mass only a tenth that of the Sun, it can keep fusing hydrogen for up to a trillion years, longer than the current age of the universe.
Answer:

Analyze the alternatives below and check the one that does NOT describe a nervous system function. 1 point
a) capture and interpret stimuli from the environment.
b) carry information.
c) creating responses through movements, sensations or findings.
d) transport nutrients and oxygen to the body.
e) control the activity of the muscles.
Answer:
d) transport nutrients and oxygen to the body.
Explanation:
Nervous system functions to communicate with other cells through synapses and through membrane-to-membrane transfer that allows rapid transmission of signals that controls muscle activity and create responses through movements, sensations or findings.
Nervous system do not function to transport nutrients and oxygen to the body.
Hence, the correct option is "d)".
