Answer:
True.
Explanation:
Vitamin D is a fat soluble vitamin that is responsible for fostering the absorption of calcium, magnesium and phosphate in the body.
The synthesis of calciferol is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet because keratinocytes of the epidermis and fibroblasts of the skin is response for producing vitamin D3(calciferol) by absorbing it from ultraviolet light when during exposure to UV B photons which protolyses provitamin D3 to pre vitamin D3 in the human body.
It can also be gotten from food sources like milk, cheese, cereals, liver,meat e.t.c.
Answer: Option C) The arrangement of atoms allows precise hydrogen bonding.
Explanation:
The individual hydrogen bonds between the base pairs confer stability to double helix of DNA.
The bases atoms take SPECIFIC POSITIONS or better still ARRANGEMENT, with Guanine pairing with Cytosine base atoms by three hydrogen bonds, while Adenine pair Thymine base atoms by two hydrogen bonds.
So, the arrangement of base atoms allows precise hydrogen bonding and hence STABILITY of DNA double helix.
The smaller flashlight has less inertia than the larger flashlight, so it takes
less force to change the motion of the smaller flashlight.
Inertia is defined as the property of an object to resist changes in its velocity
when in motion. A larger or bigger body has more mass and inertia as it
requires more force to change the direction of the object.
The smaller flashlight has less inertia than the larger flashlight and hence
requires less force to change its motion due to its smaller size.

I believe the answer is A because this is the two loop system because the air you take in from your lungs automatically is polluted. In the two loop system, the carbon dioxide is taken out out of the oxygen and is pumped back to the heart to be taken out of the body. The oxygenated blood is pumped into places it is needed.
Answer:
polarity
Explanation:
Because of its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.
