They break down the organic matter that has died so that the nutrients stored with in it can be reused.
Answer:When sunlight reaches the water; the water absorbs, lights of all colors in the white light and reflects only blue light. Thus, the earth from space appears blue. If the water absorbs all colors and reflects only yellow, then it would appear yellow.

Answer:
Consider the size of an iodine molecule and the size of a starch molecule. Make a prediction about the permeability of the baggie. Which molecule do you think will be able to pass through the membrane and where do you expect to see the color change?Consider the size of an iodine molecule and the size of a starch molecule.

Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.
DNA Replication:
<u>Step one: </u>
DNA Helicase (unzips) separates the strands.
<u>Step two:</u>
DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.
<u>Step three:</u>
DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.
- The leading strand is made continuously.
- The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.
<u>Step four:</u>
Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.
<u>Step five:</u>
Another DNA Polymerase fills in the gaps that are left behind with DNA.
<u>Step six:</u>
DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.
<u>Final answer:</u>
DNA Replication cannot replicate at the same time due to the leading and lagging strand.

Answer: The first three zones of the ocean are called the Intertidal zone, the Neritic zone, and the Open ocean zone.
The open-ocean zone is then split into 3 subzones. These subzones are called; <u>The sunlit zone, twilight zone, and the benthic zone. </u>
The sunlit zone is home to the plankton and jellyfish. The twilight zone is home to the giant squid and deep-sea hatchet fish. The benthic zone has over 200,000 plants and animal species that do not need light to survive.
