True, just look at the weather channel on TV :)
Answer: choice B. Climate
Explanation:
Climate is the relative temperature of a region over time.
When exercise does not increase bone mass, it has been observed that the risk of bone fractures increases due to osteoporosis.
<h3>What are the benefits of exercise to bone mass and density?</h3>
Bone mass refers to the mass of the bones in a living organism as a result of the deposition of minerals within the bone.
An increase in bone mass is directly related to the strength of the bone.
Strong bones have high bone masses whereas weak bone have low bone mass.
Physical activity have been shown to improve bone mass by increase the mass of deposited minerals in the bone.
Exercise such as walking, running, jogging, and other forms of exercise have been shown to improve bone mass and hence, the strength of bones.
However, when exercise does not increase bone mass, osteoporosis is observed which results in bone fracture.
In conclusion, the strength of a bone is directly related to the bone mass which is directly related to the mass of minerals deposited within them.

The tightness with which a chemical attaches to a binding site is termed its affinity for that site, while the effectiveness of the binding chemical is termed its efficacy.
Affinity quantifies how well a medication binds to a receptor (or how well it "fits the lock").
The ability of a drug-bound receptor to induce a response (or "turn the key") is referred to as efficacy.
While antagonists only have affinity for the receptors and no (zero) effectiveness, agonists have both affinities and efficacy for the receptor.
Effectiveness governs what transpires after the medication has been attached to the receptor through affinity.
The affinity (potency) and/or efficacy of different medicines that bind to the same receptor and elicit the same type of response will often vary from one another.
