(Choice D)
D
Largest fragment of DNA that traveled the slowest
Answers
Answer:
C) Smallest fragment of DNA that traveled the fastest
Explanation:
During this gel electrophoresis, DNA passes through a agarose obstacle course, where the poles opposite to wells are positively charged electrodes. Since DNA is negative in charge, when it is placed in wells and electric current is run, DNA will try to run towards the positive end.
Shorter DNA segments can easily "wiggle" through the pores of the gel whereas, longer DNA segments need to do more "squeezing" to move down the gel.
Therefore, Band X in this figure is the shorter DNA segment as it move through the lane at a faster rate and reaches very far when compared to longer DNA segments.
Smallest fragment of DNA that traveled the fastest. So, the correct option is (C).
What is Gel electrophoresis?Gel electrophoresis is defined as the technique that is used in laboratories to separate charged molecules such as DNA, RNA and proteins according to their size where the charged molecules move through a gel when an electric current is passed through it.
During gel electrophoresis, the DNA passes through an agarose barrier course, where opposite poles of the wells are positively charged electrodes, so the DNA is negatively charged when it is placed in the wells and an electric current is passed through it. DNA will try to run towards the positive end.
Shorter DNA segments can easily "squeeze" through the pores of the gel, while longer DNA segments require more "squeezing" to move down the gel. Band X in this figure is the short DNA segment as it moves through the lane at a faster rate and reaches much farther than the longer DNA segments.
Thus, smallest fragment of DNA that traveled the fastest. So, the correct option is (C).

Answers
The two groups are Tyrannosaurus Ornithomimus and Tyrannosaurus Coelophysis which are different from one another in shape and body structure.
The word Ornithomimus means ''bird mimic,” because it resembles the bird i.e. they are toothless and had beaklike jaws while on the other hand, Coelophysis means 'hollow form' and the specie has hollow limb bones that makes Coelophysis is a lightly body dinosaur that make it a fast hunter.

Answers
Answer:
Lacks the right key to unlock many cells.
Explanation:
Avian influenza (H5 N1) rarely transmitted from poultry to humans because it lacks the right key to unlock many cells in the upper respiratory tract so due to this action the virus is rarely transmitted to humans. Sometimes it is lethal to humans due to absence of antibodies for this type of virus. It is rarely spread from person to person due to inability to enters the other human body.

On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the Sahara desert. After observing it carefully you determine that it is not an autotroph, it is multicellular, and it does not contain any chitin. What is the best classification for it
Answers
Answer:
Animalia
Explanation:
A multicellular organism is an organism composed of two or more cells. Multicellular organisms include animals (i.e., organisms from kingdom Animalia), plants, and most fungi. Moreover, an autotroph is a living organism that can produce its own food by using materials from inorganic sources (e.g., water, carbon dioxide, etc); whereas a heterotroph is an organism that cannot produce its own food and thereby needs to eat other organisms, like plants or animals, to survive. Multicellular autotrophs are typically plants; whereas multicellular heterotrophs include all animals, fungi and some parasitic plants. Finally, chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is found in the cell wall of fungi, as well as in the exoskeleton of some animal groups such as, for example, insects, crustaceans, etc.

Individuals with a mutation in the gene for apolipoprotein B-100 produce very low levels of this protein, which is a component of LDL. How would accumulation of fat in the liver be affected and would this result in hypercholesterolemia or hypercholesterolemia
Answers
Answer:
Fats would accumulate in the liver and the individual would show hypocholesterolemia
Explanation:
Familial hypercholesterolemia is a genetic disorder caused by a reduction and/or defect in the low-density lipoprotein (LDL) receptor. Moreover, apolipoprotein B is the unique protein component of LDL, which plays a critical role in lipid metabolism by binding the LDL receptor. Familial defective apolipoprotein B-100 refers to an inherited disorder associated with mutations of the apolipoprotein B-100 that leads to moderate or severe cases of hypercholesterolemia. Mutations in apolipoprotein B-100 are associated with a reduction in the binding capacity of LDL to the LDL receptor, thereby leading to hypercholesterolemia.

If new genetic variation in the experimental populations arose solely by spontaneous mutations, then the most effective process for subsequently increasing the prevalence of the beneficial mutations in the population over the course of generations is
Answers
Answer:
binary fission
Explanation:
Binary fission is the main type of reproduction of prokaryotic organisms. In binary fission, the prokaryotic cell first duplicates its DNA and then divides into two cells, each one receiving one complete DNA molecule. Since binary fission is a type of asexual reproduction, this process increases the prevalence of beneficial mutations in a bacterial population. Moreover, transduction refers to the process by which a virus transfers genetic information from one bacterium to another bacterium. Conjugation is also a sexual mode of transfer of DNA from a donor (F+) to a recipient (F−) bacterial cell by direct cell-to-cell contact. Finally, transformation refers to the transfer of genetic material by which bacteria take up exogenous DNA from the environment and integrate it in their genomes.
