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:
The correct answer is A. Stability
Explanation:
In life span development patterns of growth, change, and stability are examined which occurs during the life span of a person. It is very important to study life span development because it provide information about how our brain develops and at what stage it becomes fully mature.
This maturity research can be used by lawyers to prove that a person is totally responsible for the offense he/she committed or not. Physical, social, personality and cognitive development are deeply studied in the area of lifespan development. So the correct answer is A.
Answer:
O The neuron has more potassium ions inside than outside.
Explanation:
The membrane resting potential is defined as the difference in electrical charge between the interior of neurons and their outer environment. In neurons, both sodium (Na+) and potassium (K+) pumps contribute to generating the resting potential. Neurons have a higher concentration of K+ inside than outside and a higher concentration of Na+ outside than inside. When a neuron is at its rest state, where the inside is negative with respect to the outside, its membrane is more permeable to K+ than Na+, and therefore the resting membrane potential is closer to the equilibrium potential of K+.
