What happens to a plant cell in a hypertonic solution? What happens to epidermal cells during keratinization? What regulates the flow of water through the xylem? How does a plant cell move? What happens to food energy during photosynthesis?
What happens when ethanol reacts with: a) sodium? b) potassium permanganate solution? Explain what happens in photosynthesis. What is the effect of aqeous ammonia on (NH_4)_2SO)_4.FeSO_4.6H_2O? What happens in the electrolysis of lead(II) bromide?
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. It is the driving force behind most of the life on earth. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. HOW...
What happens during dehydration synthesis? Synthesis Reactions: A synthesis reaction is one in which two or more reactants combine to form a single product. The simplest reaction would be the combination of two reactants into one product. ...
What factors speed up or slow down the rate of photosynthesis? What happens to the systemic vascular resistance values during exercise and rest? Discuss what causes the observed change with exercise. What plant hormone causes plants to grow rapidly? What role do plants play in the carbon cycle?
5. Friction: It's the force that happens when two surfaces rub against each other, making it harder to move. 摩擦力:当两个物体表面相互摩擦时产生的力,使得移动变得更困难。 6. Electricity: It's the flow of tiny particles called electrons, which powers our devices and lights up our homes....
tooth decay can be a serious problem. A science fair project provides an opportunity to demonstrate how tooth decay happens and how to prevent it. You'll need to create many samples for this project, and you probably don't have a collection of teeth for them. Don't worry. Eggshells are...
Well, recent studies have turned to biology to try to explain how this happens. Now, much of biology is studied through the lens of evolution. And the theory of evolution suggests that as environments change, and inevitably they do, some organisms will have characteristics that allow them to ...
what happens in the video. And in the video, a group of researchers go to MIT on graduation day. We chose MIT because, obviously, that's a very long way away from here, and you wouldn't mind too much, but it sort of works the same way in Britain and in the West Coast of the...
