why are active odorant receptor genes highly conserved but pseudogene versions of them not highly conservative? (4pts)
Active odorant receptor genes are highly conserved because they play a critical role in the sense of smell and the detection of odorants.
These genes have been maintained through evolutionary history due to their importance in the survival and adaptation of organisms. In contrast, pseudogene versions of these genes are not highly conserved because they have lost their functionality and are no longer necessary for survival. Pseudogenes are inactive copies of genes that have accumulated mutations over time, rendering them non-functional. As a result, they are not subjected to the same evolutionary pressures as active genes and are free to accumulate mutations without negative consequences.
Therefore, pseudogenes are less conserved than active genes because they do not serve a critical role in the survival or adaptation of organisms. In summary, active odorant receptor genes are highly conserved due to their critical role in the sense of smell, while pseudogene versions of these genes are not highly conserved because they have lost their functionality and are no longer necessary for survival.

people with chronic liver disease frequently have elevated levels of iron in their blood. iron is needed by v. vulnificus for growth. how does it acquire iron from the host?
To acquire iron from the host, V. vulnificus both produces siderophores that enable it to scavenge iron and a hemolysin that lyses blood cells to liberate haemoglobin that contains iron.
Gram-negative bacteria called Vibrio vulnificus can lead to serious, even fatal illnesses. Three separate syndromes are brought on by V. vulnificus, including gastrointestinal tract-restricted infections, an overwhelming primary septicemia brought on by eating infected seafood, and wound infections contracted when an open wound is exposed to polluted warm seawater.
Patients with chronic liver illness and hemochromatosis usually have high iron levels, which puts them at risk for developing invasive V. vulnificus infections since the microbe needs iron stores for bacterial overgrowth. Based on their observation that iron injection in mice models resulted in a reduction in 50% lethal dose, they directly connected V. vulnificus' virulence with the availability of host iron.
V. vulnificus cannot multiply in normal human serum. As a result, it is recognized that individuals with hemochromatosis are vulnerable to infection with V. vulnificus.

which is false about phosphorylase a or phosphorylase b or their relationship to each other? group of answer choices phosphorylase b is the phosphorylated version of phosphorylase a. phosphorylase a is inhibited by glucose phosphorylase b is inhibited by atp phosphorylase b is inhibited by glucose-6-phosphate phosphorylase b is activated by amp
The false statement about phosphorylase a and phosphorylase b or their relationship to each other is that phosphorylase a is inhibited by glucose. In reality, phosphorylase a is activated by phosphorylation and inhibited by ATP and glucose-6-phosphate. Phosphorylase b, on the other hand, is the non-phosphorylated form of phosphorylase a and is activated by AMP.
To avoid confusion with phosphatases (hydrolases) and kinases (phosphotransferases), phosphorylases are enzymes that catalyze the addition of a phosphate group from an inorganic phosphate (phosphate + hydrogen) to an acceptor. A phosphate group is removed from a donor by a phosphatase using water, while a phosphate group is transferred from a donor (often ATP) to an acceptor by a kinase.
The more active R form of glycogen phosphorylase, phosphorylase a, is created by phosphorylating the less active R form, phosphorylase b, with the help of AMP. The inactive T form is either dephosphorylated by phosphoprotein phosphatase with inhibition by ATP and/or glucose 6-phosphate, or it is phosphorylated by phosphoylase kinase and blocked by glucose. Dephosphorylation produces free inorganic phosphate ions, whereas phosphorylation uses ATP.

the first evidence for nucleosome formation came from digesting chromosomal dna with a non-specific nuclease. gel electrophoresis of the dna after the reaction revealed: group of answer choices
The first evidence for nucleosome formation came from digesting chromosomal DNA with a non-specific nuclease. This experiment was conducted by Roger Kornberg in 1974, and it revealed that DNA is packaged into repeating units called nucleosomes.
The non-specific nuclease used in the experiment cleaves DNA at random locations. When the chromosomal DNA was digested with this enzyme, the resulting fragments were separated by gel electrophoresis. The gel electrophoresis of the DNA after the reaction revealed a ladder-like pattern of DNA fragments. This ladder-like pattern was composed of multiples of approximately 200 base pairs in length, which corresponded to the length of DNA wrapped around a nucleosome core particle.
The nucleosome core particle is composed of an octamer of histone proteins, around which the DNA is wrapped in a left-handed superhelix.
The ladder-like pattern seen in the gel electrophoresis confirmed the existence of nucleosomes and provided the first evidence for their formation. This experiment provided a significant breakthrough in our understanding of the structure of chromatin and its role in regulating gene expression. T

b.consider the real shape of a red blood cell and allow the cell to deform as it passes through a pore of radius r. assume that the red blood cell is cylindrical with hemispherical ends. taking cell membrane area as 130um2, what is the minimum r value? you will get a cubic equation for r that you need to solve numerically.
The minimum radius of the pore that the red blood cell can pass through without breaking is approximately 4.53 μm.
To solve for the minimum radius, we need to use the formula for the surface area of a cylindrical object with hemispherical ends, which is given by;
A = 2πrh + πr²
where A will be the surface area, r will be the radius, and h will be the height of the cylindrical part of the cell.
We can rearrange this equation to solve for the height;
h = (A - πr²) / (2πr)
Now, when the cell passes through a pore of radius r, it will deform to fit the shape of the pore. The minimum radius of the pore that the cell can pass through without breaking is when the surface area of the cell is equal to the surface area of the pore. Therefore, we can set the surface area of the cell equal to the surface area of the pore, which is given by:
A = 4πr²
We can then substitute this expression for A into the equation for h;
h = (4πr² - πr²) / (2πr)
h = (3r) / 2
Now, we can substitute this expression for h back into the equation for the surface area of the cell to get;
A = 2πr(3r/2) + πr²
A = 3πr²
Finally, we can substitute the given cell membrane area of 130 μm^2 into this expression and solve for r;
130 μm² = 3πr²
r² = 130 μm² / (3π)
r ≈ 4.53 μm

The levels of cyclins vary throughout the cell cycle, and the presence of specific cyclins at the start of the S phase is necessary for CDK activation and progression through the S phase.
This CDK-cyclin complex triggers the phosphorylation of target proteins that are involved in DNA replication, allowing the cell to replicate its genetic material before cell division. Therefore, the functional activity of CDKs and cyclins is crucial for the proper initiation and progression of the S phase of the cell cycle.

the partial pressure of carbon dioxide in systemic tissues results from multiple choice pulmonary gas exchange. tissue gas exchange. pulmonary ventilation. cellular respiration.
The partial pressure of carbon dioxide in the systemic tissues results from: (4) cellular respiration.
Systemic tissues are the tissues of the body involved in the process of circulation. There main function is to provide blood supply to all the other non-systemic tissues of the body. Along with blood these tissues also supply gases and other nutrients.
Cellular respiration is the process in which the body takes in oxygen from the environment and uses it to synthesize energy to carry out the several processes of the body. Carbon dioxide is released out from the body in this. The gases of the cellular respiration travel the body through systemic tissues.
Therefore the correct answer is option 4.

on average, what percentage of the energy from one trophic level of an energy pyramid is transferred to the next trophic level?
Answer: 10%
Explanation:
According to Lindmann's 10% law
On average, about 10% of the energy from one trophic level of the energy pyramid is transferred to the next trophic level.
An energy pyramid is a structure that shows the flow of energy in an ecosystem from one trophic or nutrient level to another. The model is a graph comparing the energy used by organisms at each trophic level.
Energy transfer at the trophic level is ineffective, as not all of the biomass is transferred to the next consumer. At each stage, some usable biomass is removed as waste.
Some energy is changed to heat during respiration, and some plants and animals die without being eaten.

The traits of an individual controlled by his or her genotype are his or her genotypical inheritances.
epigenome. karyotype. phenotype. alleles.
The genotype of an individual is determined by their unique combination of alleles, which are different versions of genes that determine specific traits. The phenotype, or observable characteristics of an individual, is a result of both their genotype and the influence of the environment on their epigenome.
The karyotype, or the complete set of chromosomes in an individual's cells, is also determined by their genotype. The genotype represents the genetic makeup of an individual, while the phenotype represents the observable characteristics or traits that result from the genotype interacting with the environment. Together, an individual's genotypical inheritances shape their physical and behavioral characteristics.

Which of these is NOT true of facilitated diffusion? Responses A Membrane proteins are not specific and any available protein can be used for transport.Membrane proteins are not specific and any available protein can be used for transport. B Facilitated diffusion is a form of passive transport.Facilitated diffusion is a form of passive transport. C Facilitated diffusion moves large or charged molecules with the gradient through a membrane protein.Facilitated diffusion moves large or charged molecules with the gradient through a membrane protein. D Facilitated diffusion does not require an energy expenditure.
A) Membrane proteins are not specific and any available protein can be used for transport is NOT true of facilitated diffusion.
What is facilitated diffusion?Facilitated diffusion requires specific membrane proteins called transporters or channels to facilitate the movement of molecules across the membrane. These proteins are usually highly specific for certain types of molecules and cannot be used for transport of any other molecule.
In fact, some transporters and channels are highly selective and only allow one specific molecule to cross the membrane. Therefore, option A is incorrect as it suggests that membrane proteins are not specific for the transport of particular molecules.
