Answer:
Isotonic exercise
Explanation:
Isotonic exercise is basically weight training. It is a type of exercise where you apply force to move a static object. So to move the object, you will need to force your muscles to move them. You can use your own body as weights, use equipment like dumbbells or machines.
Isotonic exercises are good for specific workouts for specific needs. For example runners can do isotonic exercises that focuses on building leg muscles.
Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.
Answer:
The correct answer is - natural selection process does not move simply to an optimized endpoint.
Explanation:
Natural selection is a process of evolution that helps in evolving populations that are adapted to successfully reproduce and survive according to the environment.
Natural selection does not march simply to an optimized endpoint. Natural selection works upon individual organisms that have advantageous characteristics in specific environments. If the environment changes the advantages can become disadvantageous.
Thus, the correct answer is - natural selection process does not move simply to an optimized endpoint.
