Answer:
A wildfire is an unplanned fire that burns in a natural area such as a forest, grassland, or prairie. Wildfires are often caused by human activity or a natural phenomenon such as lightning, and they can happen at any time or anywhere. In 50% of wildfires recorded, it is not known how they started.
Photosynthesis makes a sugar for the plant, in order for photosynthesis to occur the plant needs carbon dioxide and water, and with the use of the sunlight it produces oxygen and glucose. For respiration you need glucose and oxygen which produces carbon dioxide, water and ATP(energy) for the cell. I hope this helps, I only know the first half of the question.
The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.
DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.
DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.
DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.
The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.
Answer:
D. the need for a surface area of sufficient area to allow the cell's function
Explanation:
Many cellular functions such as the exchange of substances and respiratory gases, absorption of nutrients, cell-cell communication, etc. require the cells to have a sufficient surface area. A small cell has a larger surface area to volume ratio and therefore, maintains a higher rate of exchange of substances. As the cell increases in size, the surface area grows less than its volume. Therefore, the surface area required to perform the cellular functions puts an upper limit on the cell size.
Cells maintain the required surface area by dividing and/or by developing folding or projections on the surface. For instance, the cells in the wall of the small intestine require to maintain a higher surface area for nutrient absorption. Therefore, the cells of the wall of the small intestine develop microvilli to have a larger surface area which in turn supports a relatively higher rate of absorption.
