3. A bacterial isolate from a urine specimen was grown in culture, Gram stained, and then tested for its ability to ferment sugars and hydrolyze various subtrates. What approach to bacterial identification is this an example of
Answer:
Phenotypic approach for bacterial identification
Explanation:
Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.
Phenotypical identification is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.
It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.
Some primary evidence is usually used for fast bacteria identification:
Gram staining, morphology, growth at different media or different incubation atmospheres, glucose fermentation, spores production, motion, aerobiosis/anaerobiosis, among others.Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is phenotypic.

Ariella is a 12-year-old whose BMI-for-age is above the 95th percentile. What conclusion could be drawn? a. She is at risk for undernutrition b. Her body fat percentage is in an unhealthy range. c. She is going through a growth spurt. d. She is at risk for future obesity.
Answer:
She is at risk for future obesity
Explanation:
The correct conclusion could be drawn is she is at risk for future obesity. BMI is a body mass index that is derived from the mass and height of the person.
How BMI is calculated?The formula is BMI = kg/m2
Where kg is a person’s weight in kilograms and m² their height in meters squared.
BMI categoriesUnderweight = <18.5Normal weight = 18.5–24.9Overweight = 25–29.9Obesity = BMI of 30 or greaterThus, it is concluded that Ariella is at a risk for future obesity according to her BMI percentile.

The absolute zero is the temperature at which molecular motion ceases i.e translational kinetic of molecules become zero, but the molecules possess the potential energy, according to the Kinetic theory of gases. Thus, the absolute zero is not the zero energy temperature.
The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?
Answer:
The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).
Explanation:
Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.
In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.
In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..
What is the phase that not all cells enter, but it is a phase where cells are not actively dividing
Answer:
The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.
Answer:
G₀ phase
Explanation:
Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.

In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,250 pine trees in 1990 and 1,500 pines in 1995.
What was the average change of the size of the population from 1985 to 1995?
What was the density of pine trees each year that they were counted?
What was the average change of density from 1985 to 1995?
Answer:
Suppose that we have a given function f(x)
The average rate of change of the function between two values x₁ and x₂ is given by:
[tex]r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}[/tex]
a) We want to find the average (rate) of change on the size of population from 1985 to 1995.
We have that:
f(1985) = 750
f(1995) = 1500
Then we have:
[tex]r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75[/tex]
This means that the population of trees increases, in average, at a rate of 75 trees per year.
b) What is the density of trees each year that they were counted?
This will be equal to the quotient between the number of trees and the area.
1985: number of trees = 750 pines
area = 250 ha
Then the density is:
D(1985) = (750 pines)/(250 ha) = 3 pines/ha
So 1985, there were 3 pines per hectare.
1990: number of trees = 1250 pines
area = 250 ha
Then the density is:
D(1990) = (1250 pines)/(250 ha) = 5 pines/ha
1995: number of trees = 1500 pines
area = 250 ha
The density is:
D(1995) = (1500 pines)/(250 ha) = 6 pines/ha
3) now we want to get the average change between 1985 and 1995 in the density, this will be:
[tex]r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha[/tex]
So, on average, each year the number of pines per hectare increases by 0.3
Which of the following events contributes to the termination of a signal generated by the binding of a ligand to a receptor tyrosine kinase? Only one answer is correct
1. Phosphatases hydrolyze key phosphorylated residues.
2. Kinases hydrolyze key phosphorylated residues.
3. Kinases phosphorylate key residues.
4. The receptor tyrosine kinase dimerizes.
5. GTPase removes a phosphoryl group from GTP.
6. Phosphatases phosphorylate key residues.
Answer:
1. Phosphatases hydrolyze key phosphorylated residues.
Explanation:
Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.

All of the following modifications to the study are likely to allow identification of new variants associated with the disease, EXCEPT ____________.
Question Completion with Options:
a. increasing the size of your cohorts.
b. increasing the diversity of your cohorts.
c. increasing the size of your affected cohort.
d. increasing the diversity of your affected cohort.
Answer:
All of the following modifications to the study are likely to allow identification of new variants associated with the disease, EXCEPT
a. increasing the size of your cohorts.
Explanation:
Option A is chosen because increasing the size of the cohorts will be equally divided between the affected and unaffected cohorts since the study discovered that these two classes are roughly the same size. Therefore, new variants of the disease may not likely be identified and isolated unless the other modification options are followed instead of Option A.
