The statement, large molecules called monomers are made of smaller sub-units called polymers is false.
Polymers are macromolecules formed by agglomeration of small molecules called monomers. Monomers are very small molecules which can join together to form long chains.
The subunits of polymers are monomers. Hence, the statement, large molecules called monomers are made of smaller sub-units called polymers is false.

Why do you think it might have a thick wax coating?
Answer:
For slow burning
Explanation:
most of the energy an organism consumes is used/converted into
Answer:
converted into
Explanation:
The higher the organism is on the trophic pyramid, the lower the amount of available energy. For example, plants and other autotrophs (primary producers) convert only a fraction of the enormous amount of solar energy they have access to into food energy.

Assume cube B was broken into many irregularly shaped pieces. Compared to the density of the entire cube, the density of one of the pieces would be
Answer:The same
Explanation: even thought the cube is split in many pieces the density stays the same
Because breaking the thing into pieces divides the mass and volume by the same factor, the density does not change. Additionally, regardless of a substance's size, its density is constant.
What is density relation with shape of object?An intensive property is density. This implies that the density of the substance will remain constant regardless of the shape, size, or amount of the thing.
Each component of the thing would have the same density even if you divided it into a million pieces.
For instance, despite the cube being divided into numerous parts, its density remains constant.
In a solid, the atoms or molecules are typically arranged in an orderly or occasionally crystalline structure,
Whereas in a liquid, they are free to move around with little restrictions. Because of this, the solid has a higher density.
Therefore, the density of one of the pieces is remained unchanged.

what will happen to energy levels in an ecosystem if the water cycle is disrupted
Answer:
Okay if the water cycle is disrupted ...the energy levels in an ecosystem will decrease
Explanation:
This is mainly because water is mainly used in energy recyclability and so that water is converted to energy through the ecosystem and the presence of water makes the energy to be there in adequate and so if the water cycle is disrupted the energy will decrease

what are 3 modifications to pyruvate in the intermediate phase
Answer:
Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.
Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.
In eukaryotes, this step takes place in the matrix, the innermost compartment of mitochondria. In prokaryotes, it happens in the cytoplasm. Overall, pyruvate oxidation converts pyruvate—a three-carbon molecule—into acetyl two-carbon molecule attached to Coenzyme A—producing an t, N, A, D, H, end text and releasing one carbon dioxide molecule in the process. Acetyl C, o, A, end text acts as fuel for the citric acid cycle in the next stage of cellular respiration.
Pyruvate oxidation steps
Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, crossing its inner membrane and arriving at the matrix.
In the matrix, pyruvate is modified in a series of steps:
More detailed diagram of the mechanism of pyruvate oxidation.
1. A carboxyl group is removed from pyruvate and released as carbon dioxide.
2. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.
3. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.

Step 1. A carboxyl group is snipped off of pyruvate and released as a molecule of carbon dioxide, leaving behind a two-carbon molecule.
Step 2. The two-carbon molecule from step 1 is oxidized, and the electrons lost in the oxidation are picked up 2 \text{NADH}NADHstart text, N, A, D, H, end text are generated from \text{NAD}^+NAD
Step 3. The oxidized two-carbon molecule—an acetyl group, highlighted in green—is attached to Coenzyme A (\text{CoA}CoAstart text, C, o, A, end text), an organic molecule derived from vitamin B5, to form acetyl \text{CoA}CoAstart text, C, o, A, end text. Acetyl \text{CoA}CoAstart text, C, o, A, end text is sometimes called a carrier molecule, and its job here is to carry the acetyl group to the citric acid cycle.
The steps above are carried out by a large enzyme complex called the pyruvate dehydrogenase complex, which consists of three interconnected enzymes and includes over 60 subunits. At a couple of stages, the reaction intermediates actually form covalent bonds to the enzyme complex—or, more specifically, to its cofactors.

why would it be better to swim in the ocean in August instead of May? Be sure to relate your answer to specific heat.
Answer:
It depends on where you are in the world. If you are in California, it would be better to swim in the ocean during August. However, if you are someplace else, it may be better to swim during May.
Explanation:
If you're in California, then August is in the middle of Summer. It is always very hot outside. Therefore, the heat should warm the water up enough for you to be comfortable to swim.
Im having lots of troubles understanding this question. if anyone could help me with the answer but most importantly how to identify the monomer in this picture that would be great you guys.
Your colleague asks you to verify her findings about a new polymer intended for use as a vascular graft. It must be reasonably elastic; otherwise, the blood will be constricted and increase its flowrate downstream with each pulse of the heart. She found that the material was sufficiently elastic for use inside the body. After running a tension test, you find that it is too brittle for use. Your colleague reviews your protocol and declares that you have either graduated from Duke or checked your eyelids for light leaks during Dr. Brudno's BME 203 class, because it definitely is adequate. Describe two mistakes you may have made. Put a (1) and (2) before each of your reasons.
Answer:
1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.
2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain can cause the material to break.Therefore not only tension test but also strain test is required.

During exercise, blood CO2 levels increase as a result of muscle cell activity. This makes blood more acidic, which disrupts pH homeostasis. Drag the following events in the regulation of gas exchange into the proper order.
I will put the events in order and further explain what happens to gaseous exchange during exercise.
During exercise,
- Blood CO2 increases,
- Blood becomes more acidic-PH decreases below the set point,
- Brain stem detects PH change,
- Brain cell signals muscles in the diaphragm and rib cage,
- Breathing level increases,
- Amount of CO2 exhaled increases,
- Blood PH returns to the set point.
During exercise,the cells of the muscles respite more than when the body is at rest.Heart rate increases abd,more oxygen is used or required and more CO2 is exhaled.
The rate and depth of breathing increases and this is in a bid for the body to compensate by making sore that more oxygen is absorbed into the blood as well as remove more carbondioxide
When CO2 combines with water, carbonic acid is formed,this makes the blood to become acidic.
Therefore,when CO2 is present in the blood,it decreases the blood PH and an excess of it (PH less than 7.35) will result in Acidosis.
