What does the Krebs cycle use to make NADH?
Answer Options are: CO2, Glucose, or Pyruvate
(Solved... the answer is Pyruvate)
Answer:
Pyruvate
Explanation:
It's a product of glycolysis the prior step.
The Krebs Cycle uses the pyruvate of Glycolysis in order to make NADH. The pyruvate from Glycolysis converts into Acetyl CoA which enters the Krebs cycle to derive NADH. Thus, the correct option for this question is C.
What is the Krebs cycle?The Krebs cycle may be defined as a type of cycle that involves a series of chemical reactions in order to liberate stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins in the form of ATP or NADH.
The process begins with the molecules of glucose which coverts into pyruvate (a molecule of three-carbon). This pyruvate is then transformed into acetyl CoA which has two carbon atoms. This acetyl CoA is then entered into the Krebs cycle in order to deliver the form of an electron which is known as NADH.
Therefore, the Krebs Cycle uses the pyruvate of Glycolysis in order to make NADH. Thus, the correct option for this question is C.

What happens during cytokinesis?
Researchers grew populations of identical Escherichia coli (E. coli) bacteria in a growth medium that contained a low concentration of glucose and a high concentration of citrate, a substance that is not typically consumed by E. coli. For thousands of generations, the bacteria used only glucose as an energy source and grew relatively slowly and to a low density because of the low concentration of glucose. After about 30,000 generations, one population emerged that began to rapidly grow to a much higher density. The researchers hypothesized that the bacteria evolved the ability to use citrate as an energy source and referred to them as Cit . To test the hypothesis, the researchers grew separate populations of the Cit bacteria and bacteria from the original population (Cit- ) in a growth medium that contained only citrate. Describe one outcome that would demonstrate that a given population has evolved.
Answer:
The colony of bacteria is called cit positive, or cit in case these advance with colonization in media with citrate, since if they grow in number and proliferate, it means that they use citrate as a metabolite or food resource for their metabolism.
Explanation:
In case these are negative cit, the profileration would have to be null or see that the colony stagnant its growth, that is to say that they did not increase in number or even decrease their number layers and they did not replicate in media with citrate.
The colony of bacteria is named cit positive, or cit just in case these advance with colonization in media with citrate.
Since if they grow in number and proliferate, it means they use citrate as a metabolite or food resource for metabolism.
In case these are negative cit, the proliferation would have to be null or see that the colony stagnant its growth, that is to say, that they did not increase in number or maybe decrease their number layers and that they didn't replicate in media with citrate.
What about E.coli?
E. coli, a species of bacteria that lives harmlessly in every person’s gut by the billions. A typical E. coli contains about 4,000 genes (we have about 20,000). Feeding on sugar, the microbe grows till it's able to split in two.
It makes two copies of its genome, nearly always managing to supply perfect copies of the first. The single microbe splits in two, and every new E. coli receives one of the identical genomes. These two bacteria are, in other words, clones.
Therefore, E.coli grows in presence of citrate that evolved in the population of 30,000 generations.

A student places a healthy potted plant and a plastic straw in a closet for two weeks. After two weeks, the student observes that the plant is wilted and brown, while the plastic straw remains the same.
The student classifies the plant as living and the plastic straw as nonliving,
What criteria does the student use to classify the plant as living rather than nonliving?
The plant needs energy from sunlight to make food for survival.
The plant produces pollen for reproduction of its species.
The plant generates sugars that are consumed as food by other organisms.
The plant produces offspring with characteristics similar to the parent plant
Answer:
According to the experiment, the criteria used by the student to classify the plant as living rather than non-living is that plant needs energy from sunlight to make food for survival.
Explanation:
One of the characteristics that defines plants as living is their ability to perform functions proper to living beings, such as nutrition, growth, development and reproduction.
Plants are autotrophic organisms, capable of producing their own nutrients from sunlight, so they require this type of energy for their nutrition and survival.
The fact that the plant that remained in the closet for 2 weeks turned brown and wither demonstrates the need it has for sunlight, which is a valid criteria for considering it a living being, in comparison with the non-living object.
The other options are characteristics of plants as living beings, but they are not the criterion that demonstrates that plants are living beings, in accordance with the proposed scenario.

They colonize soils by dispersing spores that form new mycelia. They are in a parasitic relationship with plants. They are important in natural systems and agriculture.
Answer:
They are in a parasitic relationship with plants.
Explanation:
Mycorrhizae is a fungus root that has a mutually beneficial relationship with roots of the plants and not a parasitic relationship.
Mycorrhizae colonize soil and disperse its thick-walled spores produced on the extra-radicular hyphae. Mycorrhizae are important in natural systems and agriculture as it helps in the regulation of exchange of nutrients and sugar between fungus and plant.

Let's suppose you were interested in developing drugs to prevent epigenetic changes that may contribute to cancer. What cellular proteins would be the target of your drugs?
Answer:
Potential targets:
1- DNA methyltransferases
2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.
3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.
Explanation:
Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

A particular triplet of bases in the coding strand of DNA is AAA. The anticodon on the tRNA that binds this mRNA codon is _____.
Answer:
UUU
Explanation:
A codon consists of three nucleotide bases that codes for a specific amino acid.
In the process of protein synthesis, information encoded in the messenger RNA is transferred from it by the tRNA to the rRNA of ribosomes for protein synthesis. Each transfer RNA (tRNA) has an anticodon which can base pair with a codon.
An anticodon consists of three nucleotide base sequence that is complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence.
Since in RNAs, uracil, U, is complementary to adenine, A, the anticodon on the tRNA that binds to the mRNA AAA codon is UUU.
