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.'

Bacteria:
They are single-celled prokaryotic microscopic organisms.
They reproduce through binary fission.Binary fission is an asexual mode of reproduction.Some bacteria have the ability to grow even in the presence of antibiotics.In asexual reproduction DNA of the parent cell, replicates before division.Therefore, bacteria are single-celled prokaryotic microscopic organisms that replicate via binary fission.

A scientist hypothesizes that a new medication can reduce the chances of catching a cold. Which of these would most likely be the dependent variable in a study involving this medication?
A - The participants who do not receive the medication
B - The number of participants who catch a cold
C - The age of the participants
Answer:
B - The participants who do not receive the medication
Explanation:
I like to think of the dependent variable as the outcome variable. In this case it would be the number of people that catch a cold because it depends on if they take the medication or not.

Why does DNA need to be replicated before the cell enters mitosis?
so the daughter cells can have DNA mutations
so the DNA can diversify in each daughter cell
so one daughter cell can have more DNA than the other
so each daughter cell has the same DNA as the parent cell

name three ways that you can explore specific genes to see if they would make good barcodes for species identification.
The barcode gene sequences should show less intraspecific gene variation than interspecific variation, contain conserved flanking regions and have a short length.
The three most important constraints to explore the suitability of a nucleotide sequence in order to be used as a DNA barcode for taxonomic identifications are:
Barcode gene sequences show less genetic variation within species (intraspecific variation) than between species (interspecific variation).Barcode sequences also show conserved flanking regions in order to be amplified in all species to be identified/categorized.Barcode sequences have short lengths due to technical constraints (amplification by PCR is ideal no more than 1000 base pairs).For example, in animals, an excellent barcode gene sequence used for taxonomic identification is the Cytochrome Oxidase I (COI) gene because this sequence can be used across the evolutionary spectrum.
