<span>The appropriate answer is A. the hemisphere is is tilted toward the sun and the sun reaches its highest point in the sky. This usually occurs on June 20 or 21. At this time the northern hemisphere experiences its longest day. Summer in the nothern hemisphere means that the earth is tilted towards the sun and receives sun rays that are more direct. </span>
The cell’s DNA is replicated or copied before cell division because it is important for the cell to have 2 DNA molecules because the cell is going to divide into 2. Each new cell need a 1 DNA
Glycolysis produces pyruvate as a product.
<span>A. to produce ATP and NADPH for the light-independent reactions
Remember, the purpose of photosynthesis is to provide energy for the plant to perform other chemical reactions during the process of growing. So now, let's take a look at the possible answers and see why they do or do not make sense.
A. to produce ATP and NADPH for the light-independent reactions
* Both of these are nice high energy compounds produced directly by photosynthesis. Unless we see a better option later, this looks like a good choice.
B. to convert carbon dioxide into water
* Does this provide energy to the plant? No it does not. So this is a bad choice.
C. to release oxygen into the atmosphere
* This is a happy side effect of the process for us mammals, but it's not the main purpose of photosynthesis and in fact doesn't provide energy to the plant. So wrong choice.
D. to break down glucose into pyruvic acid
* This does produce energy. But doesn't require light. So it has nothing to do with photosynthesis. Wrong choice.</span>
Density Change is when the mass/weight of an object modifies by sometimes its environment. It relates to pond life by how much weight thats in the pond and the mass of creatures, such as frogs and crocidiles
