Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

What is a macromolecule
Answer:
A macromolecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more. A substance that is composed of monomers is called a polymer .
Explanation:
as cell size increases the surface area to volume ratio
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

After photosynthesis, energy that the coral can use is stored in
molecules of?
Answers:
O2
CO2
H2O
C6H12O6
Answer:
Energy is stored in glucose molecules C6H12O6
Explanation:
Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.
These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.
Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).
Eg. for aerobic respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

READING TOOL Make Connections Fill in the concept map to show the
organization of a chloroplast. Then below, answer the questions to describe how the
different parts are related to each other.
Chloroplast
Answer:
Chloroplast -----membranes----------internal
---------external
----- Tylacoids-------------Grana
----- Stroma
You will find the complete concept map in the attached files
Explanation:
The chloroplasts are limited by two membranes, the internal and the external membranes. Both of them are separated by the intermembrane space.
In the interior of the organelle, thylakoids are composing the third system of membranes. In the interior of thylakoids, there is an additional compartment named thylakoid space. This membrane system forms piles, known as grana. Different grana structures connect to each other by a longer thylakoid membrane. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.
Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.
To fill in the diagram you will need to show the composition of the chloroplast. Therefore, you should show the internal and external membranes, the thylakoids, the grana, and the stroma.
We can arrive at this answer as follows:
Chloroplasts are organelles present in plant cells, they are very important in the photosynthetic process.Chloroplasts have two membranes, an internal and an external one, which limits the entry and exit of substances.Inside the chloroplasts are the thylakoids, which are formed by structures called grana, which form numerous piles, which resemble towers.The unoccupied space within the chloroplast is filled with a fluid called the stroma.In the figure below you can see how this diagram can be filled.

3. Climate change has been a topic repeatedly mentioned in our study of Marine Science.
How does Jackson express the impact that climate change has on corals? Based on how
he uses it, what do you infer the word symbiosis to mean?
Answer:
Climate change lead to the destruction of corals due a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
Symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.
Note: The study material was not provided.
Explanation:
Greenhouse gas emissions from human activities have led to an increase in global surface temperature. This has resulted in a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
The warming of the oceans poses a great threat to life and activities in the ocean. Coral reefs especially are affected by a warming of the ocean in the following ways:
mass coral bleaching- with increase in ocean temperature, corals remove the algae living in association with them that are responsible for their colour, thereby turning corals white. With prolonged bleaching periods, the corals eventually eventually die .Sea level rise: with rise in sea level comes a likelihood of increase in flow of sediments into the sea. This sediments when deposited on corals found near land suffocates and kill the corals.Changes in storm patterns: stronger and more frequent storms can lead to a destruction of coral reefs. Increase in the acidity of oceans results in death of corals.Corals and algae exist in a symbiotic (mutualistic) relationship in coral reefs. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.
Therefore, symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.

During the months of July, August, and September, when the squirrels are more active we would expect the artic squirrels:
A) To produce more O2 when compared to other months.
B) To have a higher output of CO2.
C) To produce less water.
D) Increase in the output of glucose.
Answer:
B) To have a higher output of CO2.
Explanation:
We would expect the artic squirrels to produce a higher output of CO₂. As with most heterotrophs, the by-product of their respiratory activities is the formation of carbon dioxide gas.
They use oxygen gas to break down glucose. The process releases energy for their life activities. The waste product is usually carbon dioxide which enters back into the ecosystem as a waste.Help please ;)))
