the guy above is wrong the actual answer is C
Explanation:
The best for a student to add to the water is a substance that releases heat when it reacts with water. Thus, the correct option is C.
What is an exothermic reaction?When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.
The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.
Therefore, the correct option is C.

the allowance for uncollectible accounts is a contra account to
The allowance for uncollectible accounts refers to a company that accepts the risk of giving credits to those who may not pay it back. These debts are written off as uncollectable and are a contra asset on the balance reports.
Uncollectable accounts are also often referred to as doubtful accounts. This implies that the company that is giving the credit accepts the possibility that this entity may not return the money. This results in a loss for the company as is recorded as a contra asset on the balance sheets for the company. Some ways for companies to control this loss are:
Establishing requirements for creditsUsing credit collectors to claim large debtsLimiting amount of loss permitted based on historical and industry records.A contra asset or contra account is an account on a companies balance sheet that decreases the balance of certain assets. Contra derives from Latin and means against. Meaning this is an account that goes against the positive balance of the company, it subtracts from the companies earnings.

Answer:
Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.
Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.
Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.

Identify the independent variable and the dependent variable in your penny
experiment?
Answer:
Independent Variable = The thing you change
Dependent Variable = The thing you measure
Explanation:
An independent variable is the thing that you are changing in your experiment to be able to get different results. For example, if a question says "What will happen to a cup of tea when you change the temperature of the water added to it?"... then the independent variable will be the temperature of the water.
A dependent variable is the thing that you are measuring. For example, if you are studying the amount of light absorbed from different surfaces, then the dependent variable is the unit of light absorbed, which would be measured in Au (Absorbance unit).

As to the model of the different types of saccharides displayed, we can name its efficiency as a clear strength, and its lack of more examples as a limitation.
Using models to display information can be advantageous in that they allow the user to visualize something that may otherwise be difficult to picture. This increases memory retention and increases learning.
One example of a strength displayed by this model is its efficiency. By this, I mean that the model provides a clear and easy way to compare the differences in structure between the types of saccharides by positioning them all onto the same page, near one another enough to make quick and easy comparisons.
The noticeable limitation of the model, however, is its lack of further examples. The model in question shows a single example for each type of saccharide, limiting the user's knowledge to the difference between the types only. After using this model, the user will still lack information as to how saccharides of the same type can vary from one another.

what determines the primary structure of a dna molecule?
Answer:
I would go with the sequence of the bases in the nucleic acid chain
The sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.
What is DNA?Deoxyribonucleic acid is a polymer which is made up of two polynucleotide chains that coil around each other to carry the genetic instructions for growth, function, development, and reproduction in all known organisms and many viruses. DNA and RNA are nucleic acids.
DNA is made up of chemical building blocks called nucleotides which are building blocks made up of three parts:
1. A phosphate group
2. A sugar group
3. One of four types of nitrogenous bases i.e. adenine (A), cytosine (C), guanine (G), and thymine (T)
To form a strand of DNA, nucleotides are linked in chains, alternating between phosphate and sugar groups.
Thus, the sequence of nucleotides defines the primary structure of DNA and RNA where the nucleotides are linked to the oxygen on the 5' carbon of one through the phosphodiester bond linking to the oxygen on the 3' carbon of the other.

Lactic acid fermentation can be modeled by which equation?
O Lactic acid + NADH → Pyruvic acid NADH
O Pyruvic acid + NAD+ → Lactic acid + NADH
O Lactic acid + NADH → Pyruvic acid + NAD+
O Pyruvic acid + NADH → Lactic acid + NAD+
Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+
LACTIC ACID FERMENTATION:
Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC. However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+. This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:Pyruvic acid + NADH → Lactic acid + NAD+Learn more at: https://brainly.com/question/11502989?referrer=searchResults
Answer to Question 1:
Well, given the choices to the question above 'Lactic acid fermentation can be modeled by which equation?', I would say that the best choice would be 'Pyruvic acid + NADH → Lactic acid + NAD+', or in other words, Option D.
Explanation for Question 1:
For a further explanation expanding more on the first question and showing why, the user above's answer is super helpful.
Answer to Question 2:
For the additional question asked 'In the Krebs cycle, how is citric acid formed?', I didn't see the options, however I believe they are:
O Carbon dioxide bonds with a chain of coenzyme A.
O Pyruvic acid molecules are broken down by an acetyl group.
O Acetyl-CoA joins with a large molecule called ozaloacetic acid.
O Enzymes combine hydrogen ions, oxygen, and electrons.
^ This being said, I would say your best choice would be Option C.
Explanation for Question 2:
The Krebs cycle begins when acetyl-CoA combines with a four-carbon molecule called OAA, aka oxaloacetate. This begins to produce citric acid, in which has six carbon-atoms. This is why the Krebs cycle is also referred to as 'the citric acid cycle.'
