Answer:
Greenhouse gases absorb this energy, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere. Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic.
Answer:
The correct answer will be options
1. The position of the tropomyosin threads shift
2. Exposing myosin binding sites
3. Allowing the myosin head to attach to the actin filament
Explanation:
Calcium plays an important role in the contraction of muscles especially in the formation of the cross-bridge between myosin and actin filaments.
In the presence of calcium, myosin head binds the actin filament as calcium binds to the troponin which changes the configuration of the troponin which releases the tropomyosin from the myosin-binding site on actin.
Once the myosin binding site is freed, myosin binds the site and causes muscle contraction due to ATP hydrolysis.
Thus, the selected options are the correct answer.
Answer:
A.
Explanation:
The muscular system provides for movement of the body and its parts, maintains posture, generates heat, and stabilizes joints.
Mainly, it's responsible for movement, posture, and stability.

The answer is A. Applied forces are the unbalanced forces a person applies to another object to change its velocity or direction or to make it accelerate. When we pull an object towards us, we are increasing it’s velocity, so it’s an applied force.
