There was a time when we were very physically active, but now we rely on devices to do most of our work. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species.

The answer to your question is:
Explanation:
<u>Double-helix</u> is the structure of dna as first published by james watson and francis crick in 1953.
Answer:
b. Only about one-half of the world's population relies on sunlight to maintain adequate vitamin D nutrition
Explanation:
Dark skin pigments slow down the synthesis of vitamin D, so black people need to spend more time in the sun to absorb enough vitamin D, so the letter A is incorrect.
Prolonged exposure to sunlight degrades the precursor of vitamin D, whereas prolonged exposure to sunlight produces vitamin D3, which acts to regulate heart function and blood pressure. With this we can conclude that the letter C is also incorrect.
Vitamin D deficiency is not caused by calcium deficiency, on the contrary, vitamin D deficiency is a cause of calcium deficiency. In addition, summer vitamin D synthesis stocks are usually not sufficient to meet summer vitamin D requirements. That is why the letter D is also incorrect.
We can conclude, then, that the correct answer is the letter B. The main source of vitamin production is through sun exposure, because type B ultraviolet rays (UVB) are able to activate the synthesis of this substance. Some foods, especially fatty fish, are sources of vitamin D, but the sun is responsible for 80 to 90% of the vitamin the body receives. It can also be produced in the laboratory and given as a supplement when there is a deficiency and for the prevention and treatment of a variety of diseases.
Life's defining characteristics are the capacity to procreate, grow, and develop. The ideas of biological control and homeostasis maintenance are crucial to survival and define important aspects of existence.
<h3>What does biology say about the meaning of life?</h3>
A living object has life when it has the ability to grow, metabolize, respond to stimuli, adapt, and reproduce. This ability sets a living thing apart from a dead thing or a non-living thing.
<h3>What traits distinguish biological life?</h3>
Big Ideas: All living organisms share a few characteristics, including cellular organization, the capacity for reproduction, growth and development, energy usage, homeostasis, and the capacity for adaptation.
