Answer:
Calcium.
Explanation:
Muscle cells are the important for the body as they are involved in the bodily movement. Three different type of muscle are smooth muscle, cardiac muscle and skeletal muscle.
The sarcoplasmic reticulum contains the stored calcium in the muscle cell. The calcium is important ion that plays an important role in the muscle contraction. The actin and myosin protein functioning also depends on the the calcium ion.
Thus, the correct answer is option (B).
Answer:
See the answer below
Explanation:
The sympathetic and sympathetic nervous systems make up the autonomic nervous system, regulating involuntary functions. The first acts in situations of fight or flight, for example in an accident of self-actions such as: increased heart rate, pupil dilation, relaxes airways, among others. Neurotransmitters are released: adrenaline and norepinephrine. The parasympathetic system performs antagonistic functions by activating in relaxation situations: it decreases heart rate, contracts pupils, constricts airways. Acetylcholine is released as a neurotransmitter.
The items of food handling that is most likely to be vulnerable of hazards is the critical control point. The critical control point is a procedure being applied to be able to prevent hazard to be contaminated to the food and in the same time to promote food safety. One of the methods that falls under critical control point is cooking, it is used to kill microorganisms that could be lurking on the food. The reason why it could be vulnerable of hazards because if it not done correctly, it could still preserve the contaminants, making it dangerous and making the people consume it at risk. Just like in cooking, when it is not done correctly, it will preserve the microorganisms, making the people consume it at risk.
What Is a Sprain?
A sprain is caused by stretching or tearing a ligament, or the connective tissue between bones. Ligaments help support your 360 joints, enabling you to move your elbows, knees, hips, and other parts of the body.
Sprains can be mild, moderate, or severe, but symptoms of all three types of sprains commonly include:
Bruising
Inflammation
Pain
Swelling
Sprains can be caused by direct or indirect trauma to a joint, such as a fall or a hit. You will typically feel a pop or tear in the joint when a sprain occurs. A severe sprain can immediately cause extreme pain because the ligament tears completely, making the joint nonfunctional. Moderate sprains are partial ligament tears that create unstable joints. A mild sprain stretches the ligament, which does not loosen the joint.
What Is a Strain?
Strains are injuries of your muscles or your tendons, which connect muscles to bone. Typically caused by overuse of muscles and tendons, symptoms of strains can include:
Cramping
Inflammation
Muscle spasm
Muscle weakness
Pain
Swelling
Severe strains can cause your muscle and/or tendon to be partially or completely torn, leading to debilitation. Moderate strains can partially affect muscle function since the muscle or tendon is likely only slightly torn. If you have a mild strain, your muscle or tendon is slightly stretched, not torn.
