Pyruvate dehydrogenase deficiency is a genetic disease most commonly linked to a mutation in the a -subunit of the mitochondrial enzyme that causes the enzyme to cease functioning. As a result of the mutation, affected individuals build up dangerous amounts of lactic acid. Which of the following best explains the buildup of lactic acid in individuals with the mutation?
a. Cells use lactic acid to shunt electrons from pyruvate to the electron transport chain in the mitochondria.
b. Cells undergo glycolysis because there is a buildup of pyruvate in affected individuals.
c. Cells cannot transport pyruvate to the mitochondria in the absence of pyruvate dehydrogenase activity, so the pyruvate is broken down to lactic acid and ethanol
d. Cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle.
Answer: The correct option is D ( Cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle).
Explanation:
Pyruvate dehydrogenase is the enzyme that converts pyruvate to acetyl CoA which enters the Krebs cycle in glucose metabolism. The deficiency of Pyruvate dehydrogenase can be caused by genetic origin most commonly linked to a mutation in the a -subunit of the mitochondrial enzyme that causes the enzyme to cease functioning. As a result of the mutation, affected individuals build up dangerous amounts of lactic acid.
The increase in the level of lactic acid occurs due to the Increased action of lactate dehydrogenase enzyme. In the absence of Pyruvate dehydrogenase enzyme, the level of blood pyruvate increases. Excess pyruvate is then converted to lactic acid by lactate dehydrogenase enzyme in a process called lactic fermentation. This results in a buildup of lactic acid in the blood leading to a condition called lactic acidosis .
Therefore, cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle.
what structure is less likely to suffer severe damage during an earthquake a high-rise steel frame Hotel built on segments or a wood frame house built on bedrock explain.
Answer:
Wood frame house built on bedrock
Explanation:
The wood frame house built on bedrock is less likely to suffer severe damage because it has a firm bedrock foundation and can be easily repaired and shape recovered since it would just be shaken whereas, the high-rise steel frame hotel built on segments will suffer more damage because it doesn't have as much of a firm foundation like the wood frame house and as such the high rise will fall over and be more difficult to recover due to the severe damage.

What is an oxidation reaction?
A. A reaction in which an atom gains 1 or more protons
B. A reaction in which an atom loses 1 or more protons
C. A reaction in which an atom loses 1 or more electrons
D. A reaction in which an atom gains 1 or more electrons
(Answer is C)
Answer:
C
Explanation:
Answer: in an oxidation reaction an element loses one or more electrons
Explanation:
An oxidation reaction was originally defined as combining an element with oxygen, e.g. 2Ca + O2 —> 2CaO
Now we consider an oxidising agent as an electron acceptor, so the reaction need not include oxygen, e.g. Ca + S —> CaS. Ca loses electrons to S.

In reviewing evidence from a cold case, Investigator Chang realizes that the original investigators did not collect any DNA evidence. She's found a possible blood spot on some clothing in evidence that could yield some DNA of the perpetrator. She also knows that the investigators had a suspect in mind but could never prove her involvement. However, the suspect was embalmed and buried five years ago.
Why will Investigator Chang be unable to collect DNA from the suspect?
DNA is no longer available after three years.
An embalmed body isn't suitable for DNA testing.
A body that has been buried in dirt corrupts DNA material.
DNA testing techniques can't extract DNA from dead bodies.

Which type of scientific statement is defined as a statement of fact that is generally accepted to be true and universal because it has always been observed to be true? O theory probability o law hypothesis sm
Answer:
C. Law.
Explanation:
A law is a type of scientific statement is defined as a statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
Some examples of laws that are universally accepted include;
I. Law of Conservation of Momentum: it states that if objects exert forces only on each other, their total momentum is conserved.
II. Law of Conservation of Energy: it states that energy cannot be destroyed but can only be transformed or converted from one form to another.
III. Newton's First Law of Motion: also known as law of inertia, it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
IV. Ohm's law: it states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
V. The three (3) laws published by Kepler include;
a. The first law of planetary motion by Kepler states that, all the planets move in elliptical orbits around the Sun at a focus.
b. According to Kepler's second law of planetary motion, the speed of a planet is greatest when it is closest to the Sun.
Thus, the nearer (closer) a planet is to the Sun, the stronger would be the gravitational pull of the sun on the planet and consequently, the faster is the speed of the planet in terms motion.
c. The square of any planetary body's orbital period (P) is directly proportional to the cube of its orbit's semi-major axis.

What influence does acid rain have on seed germination?
Answer:
Acid rain is an umbrella term, which is used
to cover a number of different pollution
processes. The pH of acid rain is ten, fold
difference between numbers. India illustrates
the drastic effect of acid rain on agricultural
productivity researchers there found that
wheat growing near a coal fired power plant
where SO2 deposition was almost five times
greater than the critical load (the amount of
the soil can safely absorb without harm)
suffered a 49% reduction in yield. In the
present investigation to assess the effect of
acid rain on the plant growth, the plant of
Triticum aestivum and Raphanus sativus
were grown in different wooden boxes and
three different plastic boxes. The different pH
(2.0, 4.0, 5.0) of simulated rain does were
sprayed on the plant and after last dose the
specific visual difference was seen in seed
germination. increased acidic level (pH 2.0) of the rain water affects the seed germination by the rate of 40% as compared to that of lower level of acidity (pH 4.0 and 5.0)

the F1 generation to look like? What
about the F2?
Drag and drop the correct flies into
the table.
NT
75%
25%
Answer:
F1: All ebony
F2: 75% ebony and 25% yellow.
Explanation:
Assuming that the ebony fly is heterozygous, it would carry one gene for yellow. So when crossed with a yellow fly they will have 75% ebony and 25% yellow offspring.
The offspring will inherit the dominant trait for ebony. But a few of the offspring will inherit all recessive traits for yellow.
The f1 generation will be all ebony.
The f2 will be 75% ebony and 25% yellow.

Dakota lives in New Orleans. He knows that scientists have predicted some changes on Earth due to global warming, and he is concerned it will affect his city.
If the climate warmed, which of the following would be caused by rising temperatures?
A. a decrease in the amount of flooding in coastal areas
B. an increase in the amount of solar energy that gets reflected
C. an increase in sea levels
D. a decrease in sea levels
Answer:
The rising global temperatures will lead to an increase in sea levels.
Explanation:
The rise of global temperatures is a natural process that has been occurring numerous times during Earth's past. What is different in the current one though is that humans also have an impact on it and have managed to speed up the process with their activity. Every increase or decrease of global tempeartures results in big changes.
With global temperatures rising, the cryosphere (ice surfaces) will decrease due to melting. How much will the ice surfaces decrease can't be predicted, but even if it's one third or one half of them, the sea levels will rise because they will get huge amounts of water from their melting. This will result in rising in sea levels and that will mean that a lot of the human population will need to migrate and a lot of the biggest cities in the world will be underwater. Such is the case with New Orleans, but also the big cities in the northeast of the United States. Not just cities though, but there are countries that can totally or almost totally be underwater, with the Netherlands, the Baltic States, many Pacific nations being among the most damaged.
Answer: THE ANSWER IS C.) "an increase in sea levels"

Pink eye is a recessive trait found in deer mice. In a cross between two individuals, both of whom are heterozygous for the pink eye mutation, the following offspring are obtained:
Normal 18
Pink eye 2
Use the chi-square test to determine if the observed numbers of offspring fit the expected numbers of offspring from this cross. The value of is: ____________
Answer:
See the answer below
Explanation:
If pink eye is recessive, it means that the normal eye is the dominant trait. According to Mendelian law, the ratio of normal to pink eye in a cross involving two heterozygous mice should be 3:1.
Chi-square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency.
Phenotype Observed Expected Chi-square
Normal 18 3/4 x 20 = 15 [tex]\frac{(18 - 15)^2}{15}[/tex] = 0.6
Pink 2 1/4 x 20 = 5 [tex]\frac{(2 - 5)^2}{5}[/tex] = 1.8
Total Chi-square = 0.6 + 1.8 = 2.4
Degree of freedom = 2 - 1 = 1
Critical Chi-square value at 95% = 3.841
The critical Chi-square value is more than the calculated value. Hence, the observed number of offspring fits the expected number of offspring.
