(Choice C)
C
Smallest fragment of DNA that traveled the fastest
(Choice D)
D
Largest fragment of DNA that traveled the slowest
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).

Mendel used more than 28,000 pea plants in his experiments. Why is it important that he studied such a large sample of pea plants?
A. The pea plants were very inexpensive.
B. Most pea plants die after producing seeds.
C. Having more samples gave him results that were closer to the predicted ratios.
D. Using more plants made the experiments take less time.
Having more samples gave him results that were closer to the predicted ratios.Mendel's experiments involved studying the inheritance of traits in pea plants. By carefully crossing different varieties of pea plants and observing the traits of their offspring, he was able to formulate the laws of inheritance that are still used today.
What does Mendel's experiments involves?Mendel's experiments involved observing the inheritance of traits in pea plants, which were controlled by genes.
By studying a large sample size of 28,000 pea plants, he was able to obtain data that was much more reliable and accurate. This is because the larger the sample size, the closer the results will be to the expected outcomes or predicted ratios, and any anomalies or errors would be minimized.
This is an important principle in statistics and scientific research, and it helps to ensure the validity and generalizability of the findings.
Additionally, by using such a large number of plants, Mendel was able to minimize the impact of any outliers or anomalous results that might have occurred in a smaller sample. This helped to ensure that his results were as accurate and reliable as possible.

how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver
Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

The great hornbill and the toucan both eat the same fruit, insects, and nuts. They both live in the rainforest. Their large bills function to get food and also as warning coloration. Which of the following is a limiting factor to the toucan population?
overlapping breeding seasons
bill coloration
genetic variability
competition
The correct answer is D. Competition.
Explanation
A limiting factor is a term that refers to the scarcity factor of a resource that limits the development and evolution of a specific species or process. According to what is described in the question, it can be inferred that the limiting factor of toucans is competition because the great hornbill lives in the same tropical forest as the toucan, it feeds on the same foods as the toucan: fruit, insects, and walnuts. So, competition for the same resources is a limiting factor for toucans since the absence of food can affect their development. So the correct respect is the D. Competition.
Many antibiotics work by preventing the proper synthesis of the peptidoglycan cell wall. These antibiotics are most likely to be effective against what types of bacteria
Answer: Gram-positive bacteria.
Explanation:
Gram-positive bacteria are those bacteria that stain dark blue or violet by Gram staining. This is due to the structure of the cell envelope, since they possess a cell wall composed of a thick layer of peptidoglycan, which surrounds the previous one. The cell wall is attached to the cytoplasmic membrane by lipoteichoic acid molecules. The peptidoglycan layer confers high resistance to these bacteria and is responsible for retaining the stain during Gram staining. Unlike gram-positive bacteria, gram-negative bacteria have a second lipid membrane outside the cell wall and a single peptidoglycan layer.
An antibiotic is a chemical substance produced by a living being or synthetically derived, which kills or prevents the growth of certain classes of sensitive microorganisms, such as bacteria. An antibiotic could be bacteriostatic if it prevents the growth of bacteria or bactericidal if it destroys them.
Antibiotics usually attack cell walls, such as β-lactams that act on the peptide chains of the bacterial cell wall. That is, they act by inhibiting peptidoglycan synthesis. This is why gram-positive bacteria are susceptible to certain types of antibiotics because they possess a large amount of peptidoglycan.

When amino acids are degraded for energy or glucose production, their amine groups are incorporated by the liver into ____.
Answer:
The correct answer is - urea.
Explanation:
In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.
The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2). This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.

Answer: A.The population of pink katydids will decrease.
B.The population of green katydids will decrease.
Explanation:
The two statements describe what will eventually happen to the population of the katydids are that:
• A.The population of pink katydids will decrease.
• The population of green katydids will decrease.
This is because from the information given, since birds started feeding on the katydids, this will result in the reduction in the number of katydids. Hence, the decrease in both the pink and the green katydids.
Answer: A: The population of pink katydids will decrease.
C: The population of green katydids will increase.
Explanation: The birds that feed on the Katydids will see the pink ones due to the green ones being camoflauged. The pink katydids will decrease and the green katydids will increase.
Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the molecule has a partial negative charge and the oxygen end has a partial positive charge. B. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. C. Both ends of the molecule have a partial negative charge, which attracts the other water molecule towards itself.
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
