Explanation:
<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).
Answer:
Option (e).
Explanation:
Nervous system is one of the most important systems of the organism that helps them to respond them towards the environment. The nervous system includes the brain, spinal cord and all the neurons.
Nervous system is present in highly complex organism and increases in complexity in case of higher animals. Lower animals do not have nervous system but still they respond to their environment with the help of chemical and receptor. Hence, all the animals have the ability to respond towards the environment.
Thus, the answer is option (e).
In the lungs, oxygen is put into the blood and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.
