Answer:
It consists of a mixture of nuclear fuel, fission products, control rods, structural materials from the affected parts of the reactor, products of their chemical reaction with air, water and steam, and, in the event that the reactor vessel is breached, molten concrete from the floor of the reactor room.
Explanation:
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!
Answer:
Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.
Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.
Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.
Explanation:
Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.
Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.
Answer:
Answer is below.
Explanation:
Photosynthesis is a process that involves three main actors (or ingredients); sunlight, water, carbon dioxide.
Statistics has it that there was no sunlight all through the day.
- Let's check then if there was availability of water and the gas carbon dioxide.
There was rainfall all day
- This means that some photosynthetic activity would take place.
What about the gas that plants breathe in?
- There is always substantial amount of CO₂ in the atmosphere.
A SECOND WAY TO LOOK AT IT IS:
by checking the two stages of photosynthesis.
- In the first stage, sunlight is the main actor. Sunlight is trapped and stored as energy in the chloroplasts of green plants.
- In the second stage, CO₂ is the main actor. With CO₂, the chemical compound - from the first stage - ATP is used to produce sugar and organic compounds which are the food of/for green plants.
