<u>Answer</u>:
Squatting to a pet dog before a run will activity create tension in the legs.
<u>Explanation</u>:
Tension in muscle contraction generates tension in the muscle fibers. In natural movements of locomotion the muscle contractions produce changes in length and tension in the muscle fibers of skeletal muscle. The sliding of protein filaments past to each other inside skeletal muscle fiber produces a contraction.
When the muscles is stretched or shortened beyond its normal level a tension which resist the change in the muscle length is felt. Among the above mentioned options the maximum tension can be observed in the following order: squatting to pet a dog > stretching your legs before a run > pressing a car's accelerator pedal > standing for five minutes (no active tension).
FOR EXAMPLE:
Let's say you've been taking melatonin every single night to help you sleep. After a while, you may notice that it begins to take more and more melatonin for it to work like it did the first night you took it. You were taking one per night, but you end up taking 3 per night to get the same effect because your body has resistant to the drug.
ANSWER:
After a while of taking antibiotics, microorganisms in your body may become resistant to the antibiotics (which is potentially dangerous). This occurs when bacteria change to reduce the effects of a drug.
Answer:
Environment affects animal behavior by changing the availability of survival resources like food & shelter, as well as situational things like proximity to human activity. Sometimes the same species of animal will behave completely differently in a forest environment compared to an urban environment.
