25 POINTS PLZ DO NOT ANSWER UNLESS YOU GOT A 90% OR BETTER ON THIS PROJECT For this assignment, you will develop a scientific model on a poster that illustrates the role of
photosynthesis and cellular respiration in the carbon cycle. Your model should also show how carbon
cycles the Earth’s four spheres. Once you have completed your model, you will write a paper with several
paragraphs describing the content of your model in more detail.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

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.
