Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.

To help your investigation, here is some more data about the farm.
The chicken population was started with chicks from a different farm.
Chickens are raised in barns where bacteria can spread easily between chickens.
CJ, E. Coli, and Salmonella bacteria are all present in the barns.
Some of the E. Coli and Salmonella bacteria have alleles that make them resistant to the FQ antibiotic.
To stop disease from growing in the barn, the FQ antibiotic is fed to the chickens a lot.
Choose which way of evolution caused the FQ antibiotic resistance.
Gene Flow
Genetic Drift
Natural Selection
What is the best fit option here? Form a hyptothesis
This is my hypothesis, is it right ?
If the chicken population is consistently given the FQ antibiotic, then natural selection leads to antibiotic resistance, because some chickens could have some of the bacterias that develop mutations allele and they can resist against FQ antibiotics.Bacteria which are resistant will continue to increases and grows in number over time. In the end, the chicken population are mainly resistant bacterial, thus making this the likely mechanism of evolution.
Answer:
1) Natural selection
2) Hypothesis: The excessive use of FQ antibiotics on chickens leads to the fixation of new genes -by natural selection- that result from mutations in the bacterial genetic material, which makes these cells become even more resistant to the drug.
Explanation:
1) Natural selection selects beneficial alleles and increases their frequency in the population.
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitat.
Let us remember that, a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed chickens´ example, we are focussing on bacteria populations.
The selective pressure or modeling environmental factor is the FQ antibiotic. The bacteria´s response to antibiotics is the survival of only those that carry mutations. Natural selection benefits these mutations. Bacteria survive and become more resistant2) Hypothesis.
First, remember that the hypothesis is a conjecture. The researcher hypothesizes in order to predict what is going on or what is expected to occur. A hypothesis is a claim of how it works a relation between two or more variables. Usually, it is written in the present time.
So in this example, we want to correlate the use of antibiotics with bacteria resistance.
I would hypothezise as following,
The excessive use of FQ antibiotics on chickens leads to the fixation of new genes -by natural selection- that result from mutations in the bacterial genetic material, which makes these cells become even more resistant to the drug.
This hypothesis probably states the same as yours but turns to be more concise. The hypothesis needs to go to the point. If you want to be more specific, you can probably add some specific hypotheses to dig into your work.
We have that the,Natural selection caused the FQ antibiotic resistance.
Natural selectionGenerally , Natural resolution causes a reaction that leads to antibiotic resistance, Mutation in micro organism make them resistant to antibiotics and when they reproduce similarly ,they will pass by this resistant trait to their offspring, which will outcomes into a completely resistant generation.
In the give up ,result is a populace of in most cases resistant bacteria.

Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form to the inactive form. Liver phosphorylase a concentration decreases when glucose enters the blood. As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. Liver phosphorylase a is regulated by AMP, adenosine monophosphate. When PP1 is bound to phosphorylase a, both PP1 and phosphorylase a are active.
Answer:
Liver phosphorylase a concentration decreases when glucose enters the blood.
The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form
As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form
Explanation:
Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase a is converted (and inactivated) into the b form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase a, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase a.

During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis.
Group of answer choices
True
False
Answer:
true
Explanation:
True. During transcription, initiation is the first step in which RNA polymerase binds to the promoter region of the DNA molecule.
The promoter is a specific sequence of nucleotides located upstream of the gene that signals the start site for transcription. RNA polymerase recognizes and binds to the promoter sequence, forming a complex called the transcription initiation complex.
Once the transcription initiation complex is formed, RNA synthesis begins. RNA polymerase unwinds the DNA double helix in the region of the gene, exposing the template strand. It then catalyzes the synthesis of an RNA molecule by adding complementary RNA nucleotides to the growing RNA chain according to the base pairing rules (A-U and G-C).
So, the statement "During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis" is true. Initiation is indeed the process where RNA polymerase binds to the promoter and initiates the synthesis of an RNA molecule based on the DNA template. This is a crucial step in the process of transcription, as it determines where and when the transcription of a specific gene will occur.
