Whats the fate of pyruvate after its produced during glycolysis?
Answers
The fate of pyruvate depends upon the availability of oxygen after glycolysis. In the presence of oxygen, pyruvate enters the mitochondria to generate reducing equivalents in the form of NADH and FADH2. And in the absence of oxygen, pyruvate exhibits fermentation.
Glycolysis is the process in which the breakdown of glucose into pyruvate occurs. This process occurs in the cytoplasm of all the cells and does not require oxygen. Glycolysis is a 10 step process where there is a net gain of 2 ATPs.
Fermentation is the process that occurs in anaerobic condition. It also happens in the cytoplasm of the cell. The products of fermentation can be either lactic acid or ethanol.

4. Why is it is more important for DNA replication to be exact than for transcription or translation to be exact? (1 point)
5. A gene has a base sequence of GTC. Due to a mutation, the base sequence changes to GTG. Answer the following questions using the codon table below.
Answers
It is more important for DNA replication to be exact than for transcription or translation to be exact because DNA is the genetic material that contains the instructions for building proteins.
The mutation from GTC to GTG within the genetic sequence induces a modification in the amino acid generated from the gene. This has the potential to exert an adverse influence on the functionality of the resulting protein.
What is mutation?A mutation denotes an alteration in the DNA sequence of an organism. Various factors, such as inaccuracies during DNA replication, exposure to mutagenic agents in the environment, or viral infections, can instigate mutations. These genetic modifications can manifest as advantageous, detrimental, or inconsequential.
Mutations serve as a significant wellspring of genetic diversity within a population. This genetic diversity plays a vital role in the process of evolution, as it empowers populations to acclimate to shifts in their surroundings.

1. What hormone is involved in regulating renal water excretion? What normally inhibits the release of this hormone? 2 pts. 2. In the last question, you stated what normally inhibits the release of the hormone controlling water excretion. From your own experience, identify two situations where this inhibition is over-ridden. For each situation explain the physiological advantage of over-riding this inhibition.
Answers
Antidiuretic hormone (ADH) or vasopressin hormone involved in regulating renal water excretion. Two situations where the inhibition of ADH release may be overridden are dehydration and blood loss.
1. The hormone involved in regulating renal water excretion is called antidiuretic hormone (ADH) or vasopressin. High blood plasma osmolality (i.e., high concentration of solutes in the blood) normally inhibits the release of ADH.
2. Two situations where the inhibition of ADH release may be overridden are dehydration and blood loss.
a) Dehydration: When the body is dehydrated, the blood plasma osmolality increases. This triggers the release of ADH, which promotes water reabsorption in the kidneys, leading to less water loss through urine. The physiological advantage of overriding the inhibition, in this case, is to maintain adequate blood volume and prevent further dehydration.
b) Blood loss: In the event of blood loss, the body needs to maintain blood pressure and volume to ensure adequate perfusion of tissues. ADH is released in response to low blood volume, promoting water reabsorption in the kidneys and helping to maintain blood volume. The physiological advantage of overriding the inhibition, in this case, is to maintain blood pressure and prevent tissue hypoxia (low oxygen supply).

Answers
Answer:
Question 13:
B. False
The most abundant photoreceptors that detect dim light are Rods, not Cones. Rods are highly sensitive to low light conditions and are responsible for vision in dim light and peripheral vision. Cones, on the other hand, are responsible for color vision and high visual acuity but are less sensitive to low light conditions.
Question 14:
A. True
The iris is the muscular tissue in the eye that adjusts the size of the pupil, controlling the amount of light entering the eye. It contracts or expands to regulate the size of the pupil in response to changing light conditions.
Question 15:
B. False
Opsins are visual pigments found in photoreceptor cells, specifically in the retina of the eye. They are responsible for capturing light and initiating the process of vision. Opsins are not derived from Vitamin D. Vitamin D is a separate compound involved in various physiological processes in the body, including calcium absorption and bone health.

3. your challenge now is to explain the inheritance of the characters you observed. for example, mendel might have explained the inheritance of pea shape this way: "Pea shape is determined by a single autosomal gene with the round allele being dominant over the winkled allele." In the space below, explain the inheritance of the characters segregating in the flies.
Answers
The inheritance of the characters segregating in the flies is determined by various genes and alleles located on different chromosomes.
The inheritance of the characters segregating in the flies can be explained by understanding the principles of genetics. In this experiment, we observed traits such as wing shape, body color, and eye color in the offspring of two different types of flies.
Based on the results of the experiment, we can assume that these traits are determined by different genes located on different chromosomes. For example, the inheritance of wing shape may be determined by a single gene on a specific chromosome.
If this gene has two different alleles, one for straight wings and one for curly wings, then the offspring will inherit one allele from each parent. If the straight allele is dominant, then the offspring with at least one copy of the straight allele will have straight wings.
Similarly, body color and eye color may also be determined by specific genes located on different chromosomes. Inheritance of these traits may be influenced by multiple alleles or complex genetic interactions.
For example, if the gene responsible for body color has three alleles (red, yellow, and black), then the offspring may inherit any combination of these alleles from each parent, resulting in a wide range of body color phenotypes.
In summary, the inheritance of the characters segregating in the flies is determined by various genes and alleles located on different chromosomes.
The specific inheritance patterns for each trait may be influenced by factors such as dominant/recessive alleles, multiple alleles, and complex genetic interactions.

In cats, white spots are caused by a dominant allele called T, while (tt) individuals are solid colored. Also short hair(H) is dominant to long hair(h). What would the probability be of getting a white-spotted, long-haired cat from this cross: TTHh x Tthh? What are the phenotypes of the parents?
Answers
Answer:
1. Probability is 1/2
2. Parents phenotypes:
TTHh = white spots, short hair
Tthh = white spots, long hair
Explanation:
This question involves two different genes coding for spot color and hair length in cats respectively. In the first gene, the allele for white spots (T) are dominant over the allele for solid color (t) while the allele for short hair (H) is dominant to long hair (h).
According to this question, a cross between parent cats was performed as follows: TTHh x Tthh. The following gametes will be produced by each parent:
TTHh - TH, Th, TH, Th
Tthh - Th, Th, th, th
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. However, according to the question, 1/2 of the offsprings will probably be white-spotted and long-haired. The phenotypes of the parents are as follows:
TTHh = white spots, short hair
Tthh = white spots, long hair
the term for the process that removes the stapes bone and inserts a piston that conducts sound vibrations is ______________________.
Answers
The term for the process that involves the removal of stapes bone and inserting a piston that conducts the sound vibrations is Stapedectomy.
Stapedectomy is a surgical removal of an original bone known as stapes and replacing it with an artificial device called a piston. This procedure is performed in order to restore the transmission of sound waves to the ear of an individual.
Three bones—the malleus, incus, and stapes—that are embedded deeply into the temporal bone within the tympanic cavity make up the ossicular chain in human bodies. The incudostapedial and incudomalleolar joints, two synovial joints, connect the three together. Together, the malleus, incus, and stapes make up our system's sound-conduction mechanism, which transfers vibrations.

maller, j., et al., common variation in three genes, including a noncoding variant in cfh, strongly influences risk of age-related macular degeneration,journal 2006, 38, 1055.
Answers
The study concentrated on three genes with frequent variations, including a noncoding variant in CFH that significantly affects the risk of age-related macular degeneration.
Age-related macular degeneration (AMD) is a common, late-onset disease with what appears to be typical complexity: family-based analysis has produced only modestly significant evidence for linkage, and recurrence ratios for siblings of an affected individual are three to six times higher than in the general population. It was found that a previously undetected common, noncoding variant in CFH, the gene encoding complement factor H, significantly increased the influence of locus on AMD in a case-control study conducted in a US-based population of European descent.
It was observed that solely additive increase of risk from alleles at these genes despite the good capacity to detect epistasis. Any variations in the associations between these loci and the main phenotypic categories of advanced AMD were not found. In the study sample, genotypes at these five common SNPs define a wide range of interindividual disease risks and account for nearly half of the traditional sibling risk of AMD.

while examining a human cell that functions normally, you determine that it has 45 functional chromosomes and one chromosome that is almost completely inactive. you immediately decide that it is very likely that this cell .
Answers
After examining a human cell that functions normally and discovering that it has 45 functional chromosomes and one chromosome that is almost completely inactive, the inference is very likely that this cell is perfectly normal.
That's because humans have two sex chromosomes: females have two X chromosomes, while males have one X and one Y chromosome. Therefore, individuals with 45 functional chromosomes and one chromosome that is almost completely inactive are perfectly normal. The inactive chromosome is referred to as an "inactivated" X chromosome.
This is a normal occurrence, and it occurs randomly in females during early embryonic development, ensuring that females do not receive a double dose of X-linked genes. Generally, the X chromosome is so large that only one active copy is required, and the other is either silenced or inactivated in females. Since males do not have two X chromosomes, they do not have an inactive X chromosome like females do. To sum up the inference, individuals with 45 functional chromosomes and one inactive chromosome are perfectly normal cell, and there is no evidence of any disease or abnormality.
