Could someone explain the answer to this? Why does the product inhibit the enzyme by binding to the allosteric site and not the active site? What difference does it make??
Answers
Answer:
it is considered non-competitive mainly because the inhibitor does no resemble the substrate that is ae to fit into the active site so it binds to the allosteric site, if it bonds to the active site then it has competition from actual substrates to fit in the active site
Explanation:
and from the metabolic pathway, we know that most likely the size of molecule A is greater than that of E since A has to be broken down through several reactions before E is produced, from this we would know that E would not resemble the structure or size of A and hence would not be able to fit in the active site of the enzyme that catalyzed A to B. From this we can deduct that the only possible thing would have been that it inhibited the allosteric site and is therefore non- competitive
Which of the following best describes sickle-cell anemia?
O Caused by environmental factors that an individual was exposed to during pregnancy.
O A hereditary genetic mutation that causes a resistance to malaria.
O An inherited disorder that increases the risk of contracting malaria from mosquitos.
O A genetic mutation that is inherited from a dominant allele of one parent.
Answers
Answer: The answer should be B "O A hereditary genetic mutation that causes a resistance to malaria."
Explanation:
I do FLVS also you can find this out in your lesson 3.04 on page 5.
It says, "Sickle-cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage. This genetic disease is recessive, meaning the allele must be inherited from both parents to be expressed in a person’s phenotype. It is caused by a mutation in the gene that produces hemoglobin, the blood’s principle oxygen-carrying protein. Sickle-cell disease occurs more commonly in people and descendants from tropical and subtropical regions where malaria is common. Scientists have discovered that individuals with just one allele for sickle-cell disease are not only healthy, but they actually have a high resistance for the parasite that causes malaria. This resistance gives the carriers of one sickle-cell allele a great advantage over malaria, which claims more than a million lives each year, and explains why the allele for this dangerous genetic disease survives to be passed down to future generations."
Have a great day hope this helped!!!

The sickle cell gene is inherited and results in sickle cell disease. You cannot catch HPV from an infected person because it is not brought on by whatever the parents did either before or during the pregnancy. Thus, option B is correct.
What are the characteristics of sickle-cell anemia?Red blood cells are typically disc-shaped and sufficiently flexible to pass readily through blood arteries.
Red blood cells with sickle cell disease have a crescent or “sickle” shape. Because sickle cells impede blood flow to particular organs, sickle cell disease complications can develop.
The severe side effects include stroke, acute chest syndrome, organ damage, various disabilities, and even early death. Acute chest syndrome lowers the blood's oxygen content.
Therefore, A hereditary genetic mutation that causes a resistance to malaria.

If you less concentrated initial solution of sodium by carbonate was used in Baker city with a solution of power more or less bio carbonate to neutralize acid why
Answers
Using a less concentrated initial solution of sodium bicarbonate in Baker City with a solution of more or less bio carbonate to neutralize acid helps to reduce the risk of over-neutralizing the acid.
What exactly do you mean by neutralization?
Neutralization is a chemical reaction in which an acid and a base react to form a salt and water. It is a type of double displacement reaction that occurs when an acid and a base are mixed together, resulting in the formation of a salt and water.
This is important in order to avoid creating an alkaline environment, which can be damaging to the environment. Additionally, the use of more or less bio carbonate can help to reduce the amount of sodium bicarbonate that is needed in order to achieve the desired neutralization.

The corn cob would float partially submerged in the water.
Density of a fluid is defined as the ratio of mass of the fluid to the total volume of that fluid. The SI unit of Density is kilograms per cubic meter. We know the substance or the fluid having lower value of the density float on the fluid having higher value of the density.
We are provided with the data,
Density of corn on the cob = 721 kg/m³
Density of water = 1000 kg/m³
We can clearly see from the data of densities that the density of corn on the cob is less as compared to the density of water. So, the corn cob would float partially submerged in the water.

There are three sources of genetic variation in sexual reproduction. Determine which of the following statements accurately describes which of these are considered random and which are not
Answers
Genetic recombination and independent assortment are considered random sources of genetic variation, while mutations can occur randomly or due to specific factors.
In sexual reproduction, the three sources of genetic variation are genetic recombination, independent assortment, and random mutations. Among these sources, genetic recombination and independent assortment are considered random processes, while mutations are not entirely random.Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material through crossing over. This process is considered random as the precise locations where recombination events occur are unpredictable.Independent assortment refers to the random alignment and separation of homologous chromosomes during meiosis I. The random positioning of maternal and paternal chromosomes contributes to genetic diversity in offspring.On the other hand, mutations are not entirely random as they can be influenced by various factors such as exposure to mutagens or errors in DNA replication. However, the specific mutations that occur at particular loci are generally considered random events.Therefore, the accurate statement would be that genetic recombination and independent assortment are considered random sources of genetic variation, while mutations are influenced by both random and non-random factors.For more such questions on Genetic variation:

What is the purpose of natural selection?
Answers
Answer:
The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.
Explanation:
The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.
Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.
It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.

When performing the smell test, Vanessa was quite good at noticing a difference between the various intensities of vanilla and also

there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Heart cells produce the protein cardiac myosin, which is critical in allowing for muscle contractions of the heart. Liver cells do not produce cardiac myosin.
Which statement explains this difference between heart cells and liver cells?
Heart and liver cells express different genes.
Heart cells rely on , R N A, , while liver cells rely on , D N A, .
Heart cells contain different genes from liver cells.
Liver cells destroyed the gene for myosin, but heart cells did not.
Answers
The most accurate statement that explains the difference between heart cells and liver cells in terms of their production of the protein cardiac myosin is "Heart and liver cells express different genes."
In multicellular organisms, different cell types have specific functions and characteristics that are determined by the genes they express. Genes are segments of DNA that contain the instructions for producing specific proteins. Each cell type expresses a unique set of genes that enable them to carry out their specialized functions.
In the case of heart cells and liver cells, they have different gene expression profiles. Heart cells specifically express the genes responsible for producing cardiac myosin, a protein essential for the contraction of the heart muscle. This allows the heart to effectively pump blood throughout the body.
On the other hand, liver cells do not express the genes for cardiac myosin production, as the liver has different functions unrelated to heart muscle contraction. The statement that heart cells contain different genes from liver cells is essentially expressing the same idea. Heart cells and liver cells have distinct gene expression patterns, leading to the production of different proteins and ultimately different cellular functions.
Both heart cells and liver cells utilize DNA as the genetic material that contains the genes responsible for protein production. RNA molecules are transcribed from DNA and play a crucial role in protein synthesis, but the distinction between heart and liver cells lies in the specific genes they express, not the reliance on different genetic materials.
