Answer:
its the 2nd one i think
Explanation:
Doesnt give a whole lot of context but this is based off of my knowledge
Ok, DNA Polymerase is an enzyme that joins free nucleotides to both existing strands of DNA, which means it isn't D (which is helicase, by the way). They normally work in pairs of two for this function, so it isn't C; this is because if it created a fork, there would only be one needed. Now, concerning A & B, you'll have to be careful. Depending on how A is worded contextually, it could be correct, or it could not. I'm not sure I like the wording "chunks." Which is why I think it's B. Polymerase joins one strand of the "unzipped" DNA to free nucleotides that match it, and these aren't "chunks of DNA." Now, Polymerase is VERY accurate, only making a mistake once every millionth (or billionth?) nucleotide matchup. When it does make a mistake (most of the time), it'll go back and fix it. So I believe the best answer is B, it checks for errors.
Hope this helps!
the amount of energy in the pyramid
Explanation:
Like all enzymes, a restriction enzyme works by shape-to-shape matching. When it comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the DNA molecule.
The sun gives off _solar___energy, which enters the atmosphere. Plants absorb some of the energy and perform photosynthesis to convert it into_chemical__energy in the form of sugars. Plants and the animals that eat them then turn that energy into a different form of _chemical___
energy, in the form of ATP. When plants and animals use the energy, it becomes _heat_ energy.
The energy producing process for life starts with the use of solar energy by plants in photosynthesis. Green plants takes up solar energy from the sun and uses it to manufacture sugar and oxygen gas in the presence of carbon dioxide and water. The sugar stores chemical energy.
When the food produced by plant is eaten, during cellular respiration, the ATP formed from break down of the food is used to liberate heat energy. The bond between the second phosphate element is broken down and heat energy is released from the stored chemical energy.
This gives off carbon dioxide and water as the by product.
