Explain how the respiratory and the cardiovascular system work together to meet the demands of the working muscle.

The respiratory and cardiovascular system work very closley in order to fulfil the demand of muscle.

When the both systems work togetehr they are called the cardio-respiratory system, which together provides oxygen for the muscle and remove carbon dioxide from the body.

During exercise when muscle require more oxygen for contraction and relaxation, cardio-respiratory systems produces more carbon dioxde as a waste product.

Cariovascular sytem helps to transport the oxygen taken by respiratory system  and work together for proper functining of muscle.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
