Answer:
D
Explanation:
From the information given:
Association rate [tex]K_a[/tex] = [tex]8.9 \times 10^3 M^{-1}s^{-1}[/tex]
dissociation constant [tex]K_D[/tex] = 10 nM
dissociation rate [tex]K_d[/tex] = ???
Using the following relation from equilibrium dissociation constant to determine the dissociation rate, we have:
[tex]K_D =\dfrac{ K_d}{K_a}[/tex]
[tex]K_d = K_D \times K_a[/tex]
[tex]K_d =(10*10^{-9} \ M) \times (8.9*10^3 \ M^{-1}{s^{-1})[/tex]
[tex]\mathbf{K_d =8.9*10^{-5} \ {s^{-1}}}[/tex]

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..

Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.
Answer:
The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.
Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.
Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

Why do scientists study seismographs?
To analyse mineral content from earth's crust
Answer:
To determine the location of an epicenter
Explanation:
A seismogram is a graph output by a seismograph ; a record of the shaking and vibration of the ground. By studying seismograms, scientists learn a lot about Earth's internal structure, like how fast the waves are moving and what type of material the waves are passing through.
When body temperature increases, thermoreceptors are stimulated and send nerve signals to the CNS. The CNS sends motor signals to sweat glands, which attempt to reduce body temperature. This is an example of a __________ reflex.a. organ.b. stretch.c. withdrawal.d. visceral.
Answer:
d. visceral.
Explanation:
The visceral reflex is one that happens autonomously in the body, aiming to maintain the balance of the body through quick responses to some specific impulses. An example of a visceral reflex is the reduction in body temperature with the release of sweat from the sweat glands.
The visceral reflexes are controlled by the autonomic nervous system, using the sympathetic and parasympathetic nervous system.
the prime mover of inspiration is the blank during normal quiet breathing expiration is a passive process as this muscle relaxes into its original dome shape. provide conditions when expiration becomes an active process or forced. explain
Answer:
The prime agonist of inspiration is the diaphragm muscle.
The conditions when expiration becomes an active process is : Emphysema, Pneumonia, Bronchitis.
-Expiration is the passive process as there is elastic recoil of lungs following inspiration without contraction of any muscles.
-The elastic fibers in alveoli are damages or filled with mucus and fluid in the disease such as conditions such as emphysema or pneumonia.
-Elastic recoil of lungs.
-Hence, muscle contraction is required to forcefully exhale the air from lungs. Internal intercostal muscles contract to pull the ribs downward and remove air from the lungs.

A scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. What molecule has likely contaminated his mixture?
nucleotide
protein
DNA
RNA
Answer:
RNA
Explanation:
A ribonucleic acid (RNA) is one of two types of nucleic acid made up of nucleotide subunits. RNA is a single stranded molecule unlike DNA, which is double stranded. The nucleotide unit of nucleic acids is composed of a nitrogenous base (Adenine, Guanine, Cytosine and Thymine/Uracil), a pentose sugar (ribose and deoxyribose) and a phosphate group.
One of the key structural differences between RNA and DNA is that RNA contains URACIL nitrogenous base instead of THYMINE in DNA.
According to this question, a scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. This illustrates that the contaminating molecule is a specific type of nucleic acid called RNA.

Why do you think so many people seem to not care about the environmental issues we are facing?
Answer:
People are not aware of their causes and impacts.
Explanation:
First, people just seem to think that a little bit of harm won't impact the world at all, but that little bit for everyone adds up and the magnitude is a lot worse than people would imagine. Next, even if they/we do know the scale, they don't know how to help or are not interested enough to try and fix the problem. We all think that we won't be able to help enough to fix the issue.
Methylene blue can be used to stain DNA because it: (2 pts) forms ionic bonds with DNA changes the pH and therefore the structure of DNA makes DNA electron dense is an effective chemical fixative for cells is none of the above
Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.

5. Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.
