General Biology Conclusion Questions (24 pts) 1. Gel electrophoresis is a classic molecular technique to separate DNA by size. An electric current is run through the gel and the DNA moves from the negative to the positive, why? (1) Explain how the gel separates DNA by size?
Answers
Gel electrophoresis separates DNA by size because DNA molecules are negatively charged and move towards the positive electrode. Smaller DNA fragments travel faster through the gel matrix than larger ones.
In more detail, gel electrophoresis works by applying an electric current to a gel matrix, typically made of agarose or polyacrylamide. The negatively charged DNA molecules are loaded into wells at one end of the gel and, when the current is applied, they migrate towards the positive electrode. The gel matrix acts as a sieve, allowing smaller DNA fragments to move through the pores more easily and quickly than larger fragments. As a result, the DNA fragments become separated by size, with smaller fragments traveling further down the gel. This technique is commonly used in molecular biology research for purposes such as analyzing DNA samples or determining the sizes of DNA fragments in a sample. **Gel electrophoresis** and **DNA separation** are important aspects of this process.

In the transmission of monetary policy, what is the difference between inside money and outside money
Answers
Inside money refers to financial assets created by banks, while outside money is money created by the government or central bank.
Inside money is primarily composed of checking and savings accounts, as well as other forms of bank deposits. It is created through the lending and deposit-taking activities of banks, which expand and contract the money supply based on the demand for loans. Outside money, on the other hand, consists of currency in circulation and reserves held by banks at the central bank. It is created through government spending, taxation, and central bank operations, such as open market operations and quantitative easing. The key difference between inside and outside money lies in their issuer: inside money is created by private banks, while outside money is created by the government and central bank. This distinction is important in understanding the transmission of monetary policy, as changes in the supply of inside money can impact interest rates and credit availability, while changes in the supply of outside money can affect inflation and overall economic stability.

glucokinase (hexokinase iv) differs from hexokinase (hexokinase i): a) by having a higher affinity for glucose and not being inhibited by high levels of glucose. b) by requiring larger concentrations of glucose before reaching maximal activity. c) to allow the liver to export free glucose to the bloodstream when blood sugar levels drop. d) so that the liver does not compete with other tissues for glucose when glucose levels are high. e) to allow the pancreas to trigger insulin release when blood sugar levels are low.
Answers
The correct answer is option A. Glucokinase (hexokinase IV) differs from hexokinase (hexokinase I) in that it has a higher affinity for glucose and is not inhibited by high levels of glucose.
The enzyme glucokinase, which is mostly present in the liver, is involved in the metabolism of glucose.
It can bind to glucose more quickly and effectively due to its higher affinity for the compound than hexokinase. Also, unlike hexokinase, glucokinase is not inhibited by high glucose levels.
Since the liver can now export free glucose to the bloodstream when blood sugar levels fall, glucokinase can continue to catalyse the breakdown of glucose. This procedure is crucial for controlling blood sugar levels.

One cause of tsunamis is earthquakes in the ocean floor. In the image, which point represents the hypocenter of an underwater earthquake?
Answers
In the image, a point which represent the hypocenter of an underwater earthquake is point D.
What is an earthquake?An earthquake can be defined as a sudden, natural shaking of the ground, especially due to movements within the Earth's crust or Earth’s interior and the lithosphere (upper mantle) which creates seismic waves.
What is a hypocenter?In Geology, a hypocenter can be defined as the starting point of an earthquake or the subsurface location (seismic rupture) at which the energy that is stored along a locked fault is first released.
On the other hand, an epicenter can be defined as the point on the surface of planet Earth, which is perpendicular to the hypocenter (focus) and directly above the earthquake’s origin.
By critically observing the image which represents the processes and phenomena associated with earthquakes and tsunamis, we can logically deduce that point D represents the hypocenter while point B represent epicenter.

You can see in this particular structure, there is a hydrogen bond between a hydrogen on the hydronium ion and the oxygen on the other water molecule.
Hydronium ions don’t exist in on their own, they’re required to have some way of balancing the charge that comes from the additional hydrogen ion. This balancing is typically done by the water surrounding the hydronium ion (H3O+H3O+) since water will outnumber the amount of hydronium atoms by orders of magnitude (there’s a lot more water than ions).
The hydronium ion in cold water is typically surrounded by 6 water molecules (probably oxygen towards the extra hydrogen but I can’t access the journal to confirm). There are some other structures like the one above, and another called the Eigen cation where the hydrogen is at the center of four water molecules (one is technically the hydronium). There’s also a very large structure that’s called the magic structure that has a hydronium ion surrounded by twenty water molecules (it’s called magic because it’s extra stable for its size).
meiosis occurs in specialized animal organs known as gonads.:T/F
Answers
True, meiosis occurs in specialized animal organs known as gonads. Meiosis is a process that occurs in sexually reproducing organisms, including animals, to produce offspring with genetic diversity.
During meiosis, the chromosomes in a diploid cell (one containing two sets of chromosomes, one from each parent) are divided into haploid cells (those containing one set of chromosomes). There are two rounds of division in meiosis, each resulting in two genetically distinct haploid daughter cells. Animals are multicellular organisms, and their cells undergo the process of meiosis in specialized organs known as gonads.
The gonads in females are the ovaries, which produce ova (or eggs), while the gonads in males are the testes, which produce sperm. During meiosis in the gonads, the germ cells undergo meiosis to produce haploid gametes that can be fertilized to produce offspring with genetic diversity.

Why are the oceans considered a large carbon sink?
A. Carbon gets transferred among all the organisms of every food chain.
B. Phytoplankton takes in carbon through cellular respiration.
C. Decomposition rates in the water are far greater than on land.
D. Water absorbs carbon directly from the atmosphere by diffusion.
Answers
Oceans are considered a large carbon sink mainly because they absorb large amounts of carbon dioxide directly from the atmosphere through diffusion. In addition, phytoplankton and other marine organisms also reduce atmospheric CO2 by using it for photosynthesis.
Explanation:The oceans are considered a large carbon sink because they have the ability to absorb large quantities of carbon dioxide (CO2) directly from the atmosphere. This process occurs through diffusion, which is why option D is correct. The water's surface is constantly in contact with the atmosphere, allowing it to absorb CO2. This ability to take in carbon dioxide helps to moderate global climate change as excess carbon dioxide can lead to global warming.
Moreover, phytoplankton and other marine organisms also contribute to the carbon sink nature of the ocean. These organisms undergo photosynthesis, which requires carbon dioxide, therefore helping to further reduce the amount of CO2 in the atmosphere. This explains why option B also contributes to the idea of oceans as a carbon sink, but it is not the main reason.
The decomposition rates in water (option C) and carbon transfer among the organisms of the food chain (option A) do not significantly contribute to why oceans are considered a large carbon sink.

When water is moving through the water cycle, what has to change in order for the water to move?
Answers
Answer:
The state of watwe
Explanation:
In order for the water cycle to happen, water has to change it's state from liquid to gas
Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called evaporation. Snow and ice can also become water vapor through a process called sublimation. And water vapor gets into the atmosphere from plants by a process called transpiration.
Because air is cooler at higher altitude in the troposphere, water vapor cools as it rises high in the atmosphere and transforms into water droplets by a process called condensation. The water droplets that form make up clouds. Water vapor can also condense into droplets near the ground, forming fog when the ground is cold. If the temperature is cold enough, ice crystals form instead of liquid water droplets.
If the droplets or ice crystals within clouds grow in size, they eventually become too heavy to stay in the air, falling to the ground as rain, snow, and other types of precipitation.

Answers
Right ventricle and pulmonary trunk, and analyzed for oxygen concentration all would contain about the same amount of oxygen. The answer is OPTION A.
The amount of oxygen that a person's blood can transport is indicated by their oxygen saturation. Even when given 100% oxygen to breathe, healthy people have oxygen saturation readings in their pulmonary arteries (PA) of 76%.
In comparison, patients with TGA had almost 100% oxygen saturation in PA. Depending on cardiac output, the normal oxygen saturation on the right side of the heart can range from 65% to 80%. Blood with low oxygen content is pumped from the right ventricle (RV) into the main pulmonary artery (MPA) via the pulmonary valve (PV).

Explain how sex-linked, codominant and incomplete dominant traits are passed on to offspring.
Answers
Sex-linked traits are genes carried on the sex chromosomes, the X and the Y chromosome. Only males carry the Y chromosome, and therefore all genes on the Y chromosome are passed down to the son. Women carry two X chromosomes; therefore, sex-linked traits can be passed on from both the mother and the father.
Examples of sex-linked traits include red-green colour blindness and haemophilia.
In codominance, both alleles are expressed in the phenotype of heterozygous offspring. The human ABO blood group is an example of codominance.
There are three alleles for the ABO gene: IA, IB, and I (i is recessive to both IA and IB). If an individual is heterozygous for both the IA and IB alleles, they will express both A and B antigens on their red blood cells. If they are homozygous for either IA or IB, they will express only one antigen on their red blood cells.
Incomplete dominance occurs when neither allele is dominant nor recessive, but instead, the phenotype is a blend of both. An example of incomplete dominance is the snapdragon flower, which has a red flower and a white flower. When the red flower is crossed with the white flower, the resulting offspring have pink flowers, which is a blend of red and white. The genotype for pink flowers is Rr, where R represents the red allele, and r represents the white allele.
When two pink flowers are crossed, their offspring will have a ratio of 1:2:1 of red, pink, and white flowers.

If Sam deposits $723 a month to his retirement account at a fixed interest rate of 4.12%, how long will it take his funds to reach $187,980
Answers
It, will take approximately 278.63 months for Sam's funds to reach $187,980 with the given monthly deposit of $723 and fixed interest rate of 4.12%.
To determine how long it will take for Sam's funds to reach $187,980, we need to use the formula for the future value of a series of equal payments (also known as an annuity). The formula is:
FV=P × (\((1+r)^{n-1}\)) / r
Where; FV is the future value (target amount) ($187,980 in this case)
P is the monthly deposit amount ($723 in this case)
r is the monthly interest rate (4.12% or 0.0412 as a decimal)
n is the number of periods (the unknown we need to find)
Rearranging the formula to solve for n;
n = log((FV × r + P) / P) / log(1 + r)
Plugging in the given values;
n = log((187,980 × 0.0412 + 723) / 723) / log(1 + 0.0412)
Now, we can evaluate this expression to find the value of n;
n ≈ 278.63
Therefore, it will take approximately 278.63 months.
