Answer: B
Explanation:
weather models based on physics that describes how air moves and heat and moisture are exchanged. Hence, option B is correct.
What are weather models?Models of the weather simulate the evolution of the atmosphere through time. The result of trillions of calculations using millions of observations as initial circumstances is a three-dimensional representation of what the atmosphere might look like in the future.
All weather models operate according to the same fundamental principles, resolving numerous intricate equations at varied locations both at the surface and in various layers (heights) of the atmosphere. These equations provide solutions for a wide range of variables, including temperature, dew point, wind speed, and many others.
Weather models are based on the law of physics. Thus, option B is correct.

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.

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.
Hope this is correct, have a great day.

Liquid nitrogen, which has a boiling point of -196C, is used for a number of purposes.
What is Liquid Nitrogen?It includes as a computer coolant, in medicine to remove warts, undesirable skin, and precancerous cells, and in cryogenics, which is the study of how materials respond to extremely low temperatures.
Additionally, it is increasingly being used at upscale restaurants to immediately freeze food and beverages or to produce a stunning cloud of vapour or fog when exposed to the atmosphere.
A relatively little amount of liquid nitrogen needs to evaporate within a room to produce an oxygen-deficient atmosphere since it has a significant expansion ratio during evaporation (one litre of liquid nitrogen can result in around 700 litres of gas).
Therefore, Liquid nitrogen, which has a boiling point of -196C, is used for a number of purposes.

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.

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.

1) The rate of evolutionary change may be slow and steady and is referred to as __________
2) _________ ___________ describes long periods of status bound by episodes of sudden change
3) The change in the genetic makeup of population due to chance is called _____
Answer:
1) gradualism
2) i have no idea
3) Evolution
Explanation:
Gradualism, Punctuated equilibrium and "genetic drift" are the respective answers.
What is Gradualism, Punctuated equilibrium and "genetic drift"?The rate of evolutionary change may be slow and steady and is referred to as "gradualism". This is the idea that evolution happens over long periods of time, with small changes accumulating gradually over generations.
"Punctuated equilibrium" describes long periods of stasis, where little evolutionary change occurs, punctuated by episodes of rapid and dramatic change. This theory suggests that evolution proceeds in sudden bursts of speciation, followed by long periods of stability.
The change in the genetic makeup of a population due to chance is called "genetic drift". This refers to the random fluctuations of allele frequencies in a population, which can occur in small populations or when there are chance events such as migration or a natural disaster that disproportionately affect certain individuals. Genetic drift can lead to the loss of genetic diversity and the fixation of certain alleles, and can have a significant impact on the evolution of a population over time.

1. Areas in ecosystems that produce more carbon than they require are known as
a. carbon sink
b. carbon neutral
c. carbon source
d. carbon bank
Answer:
c. carbon source
Explanation:
A "carbon source" refers to processes that hastens carbon release into the atmosphere more than what they absorb. Example of this is the burning of nonrenewable resources like fossil fuels.
The combustion of fossil fuels increases the release of carbon dioxide. Carbon is then being trapped into the atmosphere. This contributes to "global warming."
This is opposite to "carbon sink," which absorbs most of the carbon than they emit.
Summary how the Slow Carbon Cycle works. (where does the cycle start, How does the cycle move Earth? How does the carbon come out of the cycle?
