The connection between them is Vitamin D.
Vitamin D can be obtained from food and supplements, or synthesized by our bodies when we receive UV radiation in our skin, which is our major source. However, this vitamin comes <span>inactivated</span> and the only way to activate it is through enzymatic conversion (hydroxylation) in the liver and later in the kidneys.
This vitamin is necessary in the intestines because allows calcium and phosphorus to be observed, leading to normal growth and development of bones and teeth. Without enough vit D, bones become fragile, causing osteoporosis.
Answer:
Answer is option D.
The sun's energy is transferred through the vacuum of space to Earth by radiation.
Explanation:
The three forms of heat transfer are conduction, convection and radiation. The process of heat transfer between two solid objects in contact with one another due to a temperature difference is known as conduction. An ice cube melts while you hold it in your hand, is an example of conduction. Here, the heat energy from the hand is transferred to the ice cube and the ice melts.
Convection is the heat transfer occurs in moving materials (liquid or gas) due to the temperature difference between two regions. Hot soup rises to the top of the bowl, while cooler soup sinks to the bottom is an example of convection. The hot soup is less dense than cold soup, so it rises to the top and the cold soup at the top sinks to the bottom.
Radiation is a form of heat transfer where the heat energy is transferred through electromagnetic waves like infrared, UV rays etc. The sun's energy is transferred through the vacuum of space to Earth by radiation. Heat energy is transferred through vacuum by infrared radiation emitted by the Sun. The Earth absorbs it and turns the energy into heat.
With skepticism and open-mindedness, they both revolve around the fact that they don't "confine" themselves in an idea.
However, the difference comes with the means of not confining themselves. With skepticism, you are questioning that idea and essentially, taking that idea with a pinch of salt. With open-mindness, however, you aren't questioning the idea but rather are willing to open yourself to other ideas aside from that singular idea.
Here's an example (it's simplified, but you should understand the difference):
Skepticism: I used to believe in idea A, however after scrutinizing it I'm starting to doubt idea A.
Open-mindness: I believe in idea A, however I want to understand ideas B and C as well.
Answer:
It's B
Explanation:
Mutualism: An interaction between individuals of different species that results in positive (beneficial) effects on per capita reproduction and/or survival of the interacting populations.
Digestive bacteria and humans. Inside our bodies is what we call good bacteria(mutualism), which aids in digesting the food we take.
Which processes..? There is not enough information for a solid answer to be given.
