Chloroplasts are the organelles which take in sunlight and transform carbon dioxide + water and turn it into glucose + oxygen. If you look at plant cells under a microscope, you'll notice all of the chloroplasts hanging out towards the side of the plant that got the most sunlight.

A protein is folded and held in place by hydrogen bonds, disulfide bonds, and Van Derwalls Interactions. These are weak bonds that can be disrupted as the molecules speed up. Heat energy can cause enough movement to disrupt these bonds and denature a protein. If a protein is complex enough, the bonds cannot fall back … Read more

In a healthy cell, a signal protein can cause the cell to stop mitosis. A cancerous cell cannot stop mitosis and will not stop dividing.

Iron, obviously, and oxygen. When pairing a non-metal with a metal, we add -ide to the end of the non-metal. Therefore, if you see oxide, chloride, fluoride, etc. You can bet that it is just a non-metal that has been paired with a metal.

Because fat starts with a series of three carbons, then three oxygens, then 6 or more carbons.Off of those carbons are hydrogens. If all carbons have two hydrogens, the carbon tails are straight and can be stacked neatly. This is a fat and is saturated (dense). If some hydrogens are 'missing,' then the carbon tail … Read more

Osmosis and Diffusion are forms of passive transport. Our bodies use a lot of energy as it is. Wastes, nutrients, and water all flow into and out of our cells with no energy needed on our part. If we needed to also spend energy on these types of transport, we'd have to eat 24 hours … Read more

The tin on the product side of your equation came from nowhere. Please rewrite and double check.

There are some usual rules that can apply. Looking at a periodic table, group one is on the far left with hydrogen at the top working down to lithium, sodium (Na) potassium (K), etc. These always have a 1+ charge on them. Group 2, Beryllium, (Be), magnesium (Mg), calcium (Ca), etc. Always has a 2+ … Read more

Many things happen to gas molecules when air is heated. The atoms move faster because of the heat energy, the gases expand if they are not in a fixed volume, and if they are in a confined space, the pressure increases. There are several great java applets online with different controls that allow you to … Read more

Yes! As temperature increases, molecules are in a more excited state by the increased kinetic energy they have. A reaction depends on molecules colliding with enough force, at the right angle, and at the right orientation (facing the right way) for them to 'stick' (or react) with one another (called 'Collision Theory'). Higher energy means … Read more
