<h2>Skeletal & Cardiac Muscle</h2>
Explanation:
- A skeletal muscle is a contractile organ that is directly or indirectly attached to bone. Skeletal muscles move the body. Skeletal muscle contractions pull on tendons, which are attached to bones. If contraction of the muscle causes the muscle to shorten, the bone and, thus, the body part will move. For example, the biceps brachii is attached to the shoulder and the forearm bones
- Contraction and, thus, shortening, of the biceps brachii pulls on the tendons attached to the bones. Skeletal muscle contraction, however, doesn't always result in the movement of a body part
- Contraction of smooth muscles controlled by autonomic nervous system and contraction can be initiated by electrical or chemical signals. Actin is plentiful, lacks troponin
- Skeletal muscle is controlled by somatic motor division and always begins with an action potential
The correct option is B. It regulates body temperature.
<h3>What is homeostasis?</h3>
In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.
- This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range).
- Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.
- Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms.
- All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.

Answer:It happens because of the sun
Explanation:
The sun heats the atmosphere and creates mist
Answer:
Specific reproducing is a type of hereditary change which doesn't include the expansion of any outside hereditary material (DNA) into the life form. Or maybe, it is the cognizant determination for alluring qualities.
Explanation:
Answer:
B. Because weather is a complex interaction among many different variables that are constantly changing
