A prediction is different from both because it describes a result of a hypothesis that must be correct if the hypothesis is valid. (c.) The kinds of hypothesis that are useful for scientific investigations are the ones that are testable and an experiment can actually be created to test it. (d.)

How do we take advantage of the gas produced to measure fermentation rates Measure the distance between the top of the tube tail to the fluid level‚ use this distance to calculate the volume of CO2 gas produced at each timed interval (also

After travelling successfully though time I met a man by the name of Van Helmont and discussed some results from an experiment he was currently observing. I told him that I was from the future and scientist had discovered how the plants use chemical cycles to feed. I explained to him how plants use photosynthesis and respiration to produce sugars for food then releasing the used energy into our atmosphere. Four main factors needed to produce these processes are sunlight‚ oxygen‚ carbon dioxide‚ and

are the basis of all life on Earth. They create sugars‚ and the oxygen that we breathe. This process is also known as chloroplast. The mitochondria work in the opposite direction and breaks down the sugars and nutrients that the cell receives. Photosynthesis is the process of a plant taking energy from the Sun and creating sugars. When the energy from the Sun hits a chloroplast‚ chlorophyll uses that energy to combine carbon dioxide and water. The molecular reactions create sugar and oxygen. Plants

The process of chromatography separates molecules because of the different solubilities

The symbiotic relationship between plants and people is made possible by the differences between cellular respiration and photosynthesis. While cellular respiration occurs in all living organisms‚ photosynthesis relies on chlorophyll and is unique to plants‚ algae‚ and some bacteria. Respiration and photosynthesis are essentially the same process in reverse. During photosynthesis CO2 and H2O are converted to glucose and oxygen‚ while cellular respiration uses glucose and oxygen which are converted

8961 Yellow Carotenoid 0.9615 _EVALUATION_: Study Questions: One of the requirements for the photosynthesis process to occur‚ the plant cells need sufficient light. Pigments are the substances that absorbed visible light. Different pigments absorb light of different wavelengths. From the absorption spectrum of chlorophyll a‚ it suggests that blue and red light work best for photosynthesis. There is a high degree correlation between the absorption spectra of leaf and the absorption spectra
