A student combined equal amounts of two solutions. One solution had a pH of 2 and the other had a pH of 12. Which would most likely be the resulting pH?
Answer:
This question lacks options, the options are:
A. 1
B. 3
C. 6
D. 11
The answer is C. 6
Explanation:
pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.
* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic
* A pH value of exactly 7 is said to be NEUTRAL
* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.
According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.
Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.

Answer:
B. Bald eagles are hunted until near extinction, population recovers
Explanation:
A bottleneck effect can arise when the population of a species is drastically reduced by an occurrence. Human activities plays a major role in regard to creating a bottleneck effect in our present day. Human activities such as overhunting result into bottleneck effect. When overhunting reduces the population of a particular species, the few individuals left would have a reduced genetic variation which is not representative of the original population. The few individuals left further reproduces individuals of their kind carrying a genetic composition that is different from the original gene composition of the old population.
The case of the hunting of bald eagles until near extinction before they begin to recover is a perfect case of the bottleneck effect. Only a small proportion of the eagles original population survives. Generic variation reduces. The genetic variation in the new population of the bald eagles will be different from that of the original population.

a permanent disease process that is characterized by destruction of the alveolar walls and distention of the alveolar sacs is a type of COPD called
Answer:
Emphysema
Explanation:
Pulmonary emphysema disease progressively destroys the fibers that promote respiration, leading to a decrease in respiratory function, emphysema being a more serious complication of any bronchopulmonary obstructive inflammation. In emphysema, the walls that separate many of the alveoli are damaged and gas exchange in the lungs decreases. This disease originates when the pulmonary alveoli are progressively destroyed and difficulty in breathing becomes greater and greater. When destroyed, a larger space is created, instead of small chambers. And this affects the length of the lungs and the amount of oxygen that reaches the blood.

A triplet of bases in a template strand of DNA is GAT. What would be the corresponding codon for mRNA?
СТА
CUA
CTU
CUA (This one is wrong)
I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!
Answer:
CUA
Explanation:
Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.
DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)
RNA has 4 bases: AUGC (RNA lacks the base T so A binds with U instead).
So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.
A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) in a sequence.
Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.
Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

Answer:
a. The hog farmer does not notice the barn smell from the working boots when he wears them on the porch of the house.
Explanation:
The hog farmer does not notice the barn smell from the working boots when he wears them on the porch of the house is the example of sensory adaptations. Sensory adaptation is a decrease in sensitivity to a stimulus after regular exposure to it. So the farmer can't smell his own boots due to regular exposure to the smell so we can say that it is an example of sensory adaptations..

DONE
Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Proteins are responsible for the structures and functions of organisms.
What is Protein?Large, intricate molecules classified as proteins perform an array of essential roles in the human body. They are fundamental for the structure, operation, and control of the body's tissues and organs and perform out the majority of their work inside cells.
Many thousands of amino acids, which seem to be smaller components that make up proteins, are linked together in lengthy chains to form proteins. To form a protein, 20 different kinds of amino acids can be mixed. Each protein's precise function and characteristic 3-dimensional structure are established by its amino acid sequence.
Thus, Proteins are responsible for the structures and functions of organisms.

What is the role of reverse transcriptase in DNA technologies?
A. To unzip DNA strands
B. To find mRNA
C. To produce proteins
O D. To make cDNA
Answer:
D...........................................................................
Explanation:
Reverse transcriptase may be a DNA polymerase enzyme that transcribes single-stranded RNA into DNA.
What is reverse transcriptase?
This enzyme is in a position to synthesize a double-stranded DNA into a single-strand DNA once the RNA is transcribed in 1st step. Found in retroviruses, like the human immunodeficiency virus (HIV).Reverse transcriptase is used to form a cDNA copy of the mRNA. The cDNA sample is then amplified by PCR. This yields multiple copies of cDNA without intronsThus, we can conclude that the correct option is D.
To make cDNA is the role of reverse transcriptase in DNA technologies.
