Your first assignment is to find an article talking about a scientific topic. This article can be from a source of your choosing (such as a newspaper or an internet article). You will need to include the article with your assignment. Once you have your article, you will write a short paper identifying two inferences made in this article and the facts the writer used to make these inferences. Then, elaborate on whether the two inferences made by the author are valid or more opinion-based. Be sure to include your reasoning of why you came to this conclusion. Some examples of where you can find articles about scientific topics are:

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).
You can now take this knowledge and apply it to your question.

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.'

select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated cell divisions. choose all that apply.
Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
The food we eatThe environment we expose the cell toThe substances that touch the cell (e.g skin cells)That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.
Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

Answer:
to study the nature and size of the image formed by a convex lens using a candle and a screen activity file
The statement that describes nuclear fission is as follows:
Starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.Thus, the correct option for this question is D.
What is Nuclear fission?Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.
Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.
Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.

When liquid turns into vapor
Explanation:

mark as brainliest plz? :)
A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.
Temperature, surface area, wind speed, and humidity affect a liquid's evaporation rate.
Latent heat is a form of energy held in the evaporated water when it evaporates and cools.
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

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.

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.
