Answer: Skeletal muscle is a heavy consumer of energy.
eselson and Stahl relied on equilibrium density gradient centrifugation to resolve the DNA containing 14N from the DNA containing 15N.They started off with DNA in media containing the heavy isotope, then switched to media containing the lighter isotope and allowed DNA replication to take place. Under semiconservative model of DNA replication, after THREE rounds of replication, how many bands of DNA would you see and which band would contain more DNA molecules
Answer:
The correct answer would be - two bands ( one intermediate, and one light)- the light band contains more DNA molecules.
Explanation:
After the switching to the lighter isotope by the second round of replication where light strands are used as template strands, produces the light band of 14N.
After three rounds of semiconservative replication, where template strand contains both heavy and new formed light bands or nitrogen and produces so in a Density gradient, there will be 2 bands one light band and the other intermediate band.

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.
Would you want to have your DNA profile kept in your medical record as a reference for your doctors? Explain your answer. (2 points)
What are potential pros and cons of having such tests done and referring to DNA sequences when determining a patient's medical treatment? (5 points)
Describe how the availability of this technology might affect the frequency of genetic diseases in individuals and populations. (3 points)
Answer:
1. It should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. There are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but I can't think of an example where the fears didn't turn out to be baseless.
2. Yes. First, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. The pros involve better medical treatment. The cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. Looking at DNA markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. And OK, actually I suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency.

This model of the cell cycle includes two arrows that each represent a process in the cycle. What do the two arrows represent?
A.Arrow 1 represents interphase, and Arrow 2 represents mitosis.
B.Arrow 1 represents meiosis, and Arrow 2 represents prophase.
C.Arrow 1 represents prophase, and Arrow 2 represents interphase.
D.Arrow 1 represents mitosis, and Arrow 2 represents meiosis.
About the question:
You will find the model of the cell cycle in the attached files
Answer:
A. Arrow 1 represents interphase, and Arrow 2 represents mitosis.
Explanation:
When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
Interphase: Represented by arrow 1.
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.
Once the whole interphase is completed, mitosis occurs.
Mitosis: Represented in the cycle by arrow 2.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the whole-cell first duplicates and then separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). During prophase, chromosomes condensate, and the nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, cytokinesis occurs.

Which of the following does NOT occur during interphase?
1.each chromosome replicates
2.the nucleus disappears
3.microtubules extend from centrosomes
4.centrosomes are duplicated
Answer:
The nucleus disappears
Explanation:
The nucleus does not disappear in interphase but instead, the cell grows and splits to make another duplicate of the cell. Which means the cell will also split to make another duplicate nucleus.
Which of the following best describe gas particles?
SELECT ALL THAT APPLY
a moving randomly
b collide into each other
Cmove slow
d high kinetic energy
moving orderly
e moving orderly
Answer:
a, b, d (see below)
Explanation:
So, looking at the 3 states of matter:
Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)
Liquid - holds shape of its container and has particles with some space in between them that allow them to flow
Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around
Refer to the image below for a better visual understanding.
So, now, looking at the answer choices:
a) moving randomly
Yes. They are—they're speeding around super fast all the time.
Every time heat is added to something, the particles start loosening up and moving. A lot.
So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.
Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves super fast
b) collide into each other
Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.
Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.
c) move slow
No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.
d) high kinetic energy
Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.
Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.
e) moving orderly
No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.
(refer to my bumper car example in answer b, in bold)

What might happen to the Earth if human increase the amount of greenhouse gasses?
Explain your answer.''
Answer:
Global warming will occur
Explanation:
Greenhouse gases are special gaseous compounds that have this ability to trap HEAT due to their structural composition. They include; carbon dioxide (CO2), chlorofluorocarbons (CFC), methane (CH4) etc.
Anthropogenic activities such as burning of fossil fuels etc. release these gases into the atmosphere where they cause harm to the Earth. Greenhouse gases contribute immensely to the GLOBAL WARMING EFFECT, which is the increase in the temperature of the Earth surface. Therefore, if humans increase the amount of greenhouse gases in the atmosphere via their actions, there will be a GLOBAL WARMING occurrence.

Which situation shows a nonrenewable resource in use?
A. Solar energy reaches Earth's surface.
B. Sunflowers grow from sunflower seeds.
O c. Computer chips are made from silicon.
D. Lobsters are caught off the coast of Maine.
Answer:
c. Computer chips are made from silicon.
Explanation:
Non-renewable resources are natural substances that cannot be easily replenished when used. Examples are natural gas, coal, oil, nuclear energy, etc. Silicon is made when Silica is heated with carbon after which the product is reacted with hydrocarbons to polymerize them. Since the hydrocarbons are made from oil and natural gas, the resulting product is non-renewable.
Chips made from silicon are not biodegradable because to reuse them, they must be sent to companies that have specialty in renewing them.
