Answer:
Diffusion
Explanation:
The movement of molecules and ions from a region of higher concentration gradient to the region of lower concentration gradient of the molecules. Its direction of movements depends totally on the direction of the concentration gradients.
Fick's Law is the principal law that underscores diffusion. And it sates that the rate of diffusion is directly proportional to the concentration gradients or differences; the surface area available for the molecules to pass through ;<u> but inversely proportional to the thickness of the separating membrane (diffusion distance. </u>

Thus the larger the surface area exposed the more molecules pass through into the membrane , the higher the concentration differences the greater the number of molecules willing to break free and escape; but the thicker the separating membranes, the slower the number of molecules getting chances to pass through and the lower the rate of diffusion.
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:
Humans should really eat meat because our body are meant for the meat and it can’t cause cancer and many other health problems. All of the myths on meat are actually people blaming something. Meat are proven to be very nutritious and we are actually evolved to eat meat. It is not just the benefits that people will get from the meat but also get the taste. Thus there is no evidence that suggest a non meat diet will give more health benefits than a normal diet.though being a vegetarian is healthier .So humans should eat meat.
