Suppose the stereocilia of one hair cell become permanently bent toward the kinocilium. What will most likely happen as a consequence
Answer:The options are not given, here are the options from another website.
a. A single pitch will be constantly perceived
B. A single pitch will no longer be perceivable
c. A or B depending on the hair cell's location
d. A or B depending on the bending's direction.
The correct option is d.
A or B depending on the bending's direction
Explanation:
This is because stereocilia are normal bent where there is a shearing force that occur when there is a up and down movements of the basilar membrane . When stereocilia bend towards the kinocilium, it make it depolarizes the cell and lead to the afferent activity to rise up and when the stereocilia bend away from the kinocilium , it hyperpolarizes the cell and lead to a reduction in afferent activity.
The consequences of this are that a single pitch will be noticed, or no pitch will be noticed. This will depend on the direction the stereocilia have bent.
We can come to this answer because:
Stereocilia are cellular accessories that help cells move around.They can curve up or down, generating different but very important effects.If the curvature is made towards the kinocilium, we can notice the formation of a pitch, as the cell becomes polarized.If the curvature is in the opposite direction to the kinocilium, the cell will be depolarized and it will not be possible to visualize the pitch.In this case, we can state that the consequences of the curvature of the stereocilia will depend on the side towards which this curvature is directed.

7. Once anaerobic respiration takes place, are the effects permanent? Why or why not?
If a tutor can give me the answer that would be very helpful
Once anaerobic respiration takes place, the effect is not permanent. When enough oxygen is available, the cell uses the oxygen to oxidise the glucose.
What is anaerobic respiration?In anaerobic respiration, oxygen is not used for the oxidation of glucose, and as a result, very little energy is produced. Glucose undergoes glycolysis and forms pyruvate. Without the presence of oxygen, lactic acid and ethanol are formed from the glucose.
When a person runs too fast, he can't breathe properly, and muscle cells don't get enough oxygen. Due to this, glucose undergoes anaerobic respiration and forms lactic acid. As less energy is produced, more is required by the cell, and a muscle cramp takes place.
When the person gets enough oxygen, this process will reverse as the cells get enough oxygen to completely oxidise the glucose. Due to the lactic acid formation in muscles, the blood pH declines, making the blood acidic.
Hence, when enough oxygen is available, this effect of anaerobic respiration will reverse.

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Answer:
B
Explanation:
In order to identify genes that function together in genetic pathways researchers can perform modifier screens, looking for second site enhancers or suppressors of a mutant. Which of the following is the most reasonable strategy for carrying out a suppressor screen in particular?
a. analyze the DNA sequence near the mutation of interest, looking for sequences that may act as silencers.
b. identify mutations that, when crossed with the original mutant, result in synthetic lethality.
c. mutagenize the original mutant and look for new mutations that reduce the severity of the original mutant phenotype.
d. screen for enhancer-trap strains that show gene expression differences in the original mutant.
e. isolate mutants with phenotypes similar to the original mutant phenotype and then cross the mutants to identify the affected genes.
Answer:
c. mutagenize the original mutant and look for new mutations that reduce the severity of the original mutant phenotype.
Explanation:
A suppressor screen is a technique employed to identify a second mutation (i.e., a suppressor mutation) capable of reverting/alleviating the phenotypic effects associated with an initial mutation. There are two types of mutants obtained from this approach: 1-Intragenic suppressors, which involve second mutations inside the gene that restore the original function of the mutated gene; and 2- Intergenic suppressors, also known as extragenic suppressors, which involve second mutations in a gene that is distinct from the original mutated gene (usually extragenic suppressors function in the same signaling pathway as the original mutated gene).

Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
What is the purpose of the theory of evolution?The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.
With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
