You plan to clone a guide RNA sequence into the pML104 plasmid because you want to engineer the construct in bacteria and later express it in yeast. Unfortunately, your lab does not have any available pML104. Your friend in the lab next door lets you borrow a related plasmid pML107, and you quickly start your experiment. Will it work? Briefly explain.

Answers

Answer:

Yes, the experiment will work.

Explanation:

The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.

Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.

We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.

1. Robin carries the trash from the house to the garbage can outside. Which statement best describes the science of what he did?

He would use less energy if he were to move the garbage faster

He used energy to carry the garbage.

He did not have to work because garbage is light.

He caused the garbage to have potential energy when it moved.

Answers

Answer:

He used energy to carry the garbage.

Explanation:

Energy is the ability to do work. When work is done, energy is expended during the process. Work is done if the force applied on an object moves that object through a distance.

In the case where Robin carries the trash from the house to the garbage can outside, work is done because, the force applied by Robin on the trash effectively helps to move the trash from inside the house to the garbage can outside the house. During the process of moving the trash, Robin expends or uses energy to do the work.

From the given options:

He would use less energy if he were to move the garbage faster is wrong because an increase in speed results in an increase in energy

He used energy to carry the garbage is correct because energy is the ability to do work

He did not have to work because garbage is light is wrong because as long as an object is moved a distance, work is done irrespective of the mass of the object.

He caused the garbage to have potential energy when it moved can only be true if he had raised the garbage from the floor to a height above the ground. However, he only moved it fro inside to outside the house.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.

Answers

Answer:

81/256

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.  

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.

Answers

Answer and Explanation:

An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface.  These rings can be cut into various sizes. An oil ring has an axial.

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.

Answers

Answer:

I so I am also a bit confused, but I hope this could answer your question!

Explanation:

The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine.  The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.

The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.

This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.

3. A population of 70 jaguars lives in a rainforest measuring 350 square miles. What is the population
density of the jaguars? (Hint: You cannot have a fraction of a jaguar)

Answers

Answer:

5 jaguars per square mile.

Explanation:

If you do 350 ÷ 70 it comes to 5, so that means it's 5 jaguars per square mile. Have a fun day. :)

The population density of jaguars in the rainforest is 0.2 jaguars per square mile.

To calculate the population density, we divide the total number of individuals (70 jaguars) by the area of the habitat (350 square miles).

Population density = Total number of individuals / Area

Population density = 70 jaguars / 350 square miles

Simplifying the calculation, we find that 70 divided by 350 equals 0.2. Therefore, the population density of jaguars in the rainforest is 0.2 jaguars per square mile.

Population density is a measure of how concentrated a population is within a given area. In this case, it tells us how many jaguars are found on average in each square mile of the rainforest. A population density of 0.2 jaguars per square mile means that, on average, there are 0.2 jaguars in every square mile of the rainforest.

It's important to note that population density can vary across different habitats and species. Factors such as food availability, territory size, and reproductive behavior can influence the distribution and concentration of individuals within a given area. Understanding population density helps researchers assess the health of a population, monitor changes over time, and make informed conservation and management decisions.

The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years ago. Can you think of any reason why this might be happening?

Answers

Answer:

The effects of climate change may be associated with the increased incidence of V. vulnificus infection

Explanation:

Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

The organism will absorb less oxygen, reducing its ability to produce sugar
The organism will absorb less water, reducing its ability to create DNA

Answers

Answer:

the organism will have less chlorophyll

Explanation:

chloroplasts contain chlorophyll

Chlorophyll is a green pigment, without it a plant is discolored meaning it lacks of chlorophyll. Less photosynthesis would occur, and less glucose is made as a result. There is less energy released for growth as glucose is needed for respiration.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis

Answers

Answer:

The color of light determines how effective chlorophyll pigment will be at absorbing light.

Explanation:

Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.

Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.
