Explanation: i just did the quiz on k12 :) and i put answers to all the questions if u go serch it up on brainly
In the table below, all organisms have the same four nitrogenous bases in common with each other. The correct option is d.
What are nitrogenous bases?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.
The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine. But in RNA, it is uracil with adenine. Guanine and cytosine are the same.
Therefore, the correct option is d. The same four nitrogenous bases are in common with each other.

What roles did the distribution of disease and biological plausibility play in suggesting the hypothesis that supplemental oxygen causes infant blindness?
The correct answer to the question is Supplemental Oxygen.
The oxygen supplied from outside which is necessary for certain individuals as the name suggests is required as a result of unavailability of oxygen internally and as well resulting in inability or difficulty to breathe and this is the term commonly used for Oxygen Therapy.
On the other hand,Biological plausibility is an integral and essential tool and the establishment of correlation is a means of causing any hypothesis that has been formed and the availability of oxygen that is internally causing inability of difficulty in breathing and this is the common term used for Oxygen Therapy. On the other hand Biological plausibility is an essential tool used to bring about correlation as a means of causation of any hypothesis that is so formed.
Also in the case when Supplemental Oxygen causes blindness in infants,this is basically seen infants who are premature and require oxygen because their lungs are not yet developed. This said oxygen therapy was first introduced to pilots in world war II, and that was in 1940,with the high dose of oxygen in infants,there were cases of blindness as a result,the cause of blindness in infants was considered to be high dose of oxygen.
This was discovered when when. the back of the eyes was examined and it showed blood vessels proliferation and also fibrosis and this resulted in blindness. But when proper investigations was carried out,it was discovered that long term duration of the adminstration of oxygen can result to blindness.
Knowing these,and the effects of the high dose of oxygen is then supplied to premature kitten, thereafter,they developed retinal damage which inturn caused blindness.
After lots of examinations,Further cohort studies was carried out in various hospitals,this is to prove the cause of supplemental oxygen and this is done with different procedures, It was discovered that when oxygen is used less aggressively,it causes the reduction in blindness by around 7%.
Therefore,to to avoid such condition,There is the recommendation of American Academy of paediatrics and it was also brought to publication that very high rates of oxygen therapy cases blindness and this needs to be done at low dose.
Eventhough this hasn't been subjected to full experiment and it is still undergoing some procedures for checking the result of the amount of oxygen and and also the result on the duration of supply,we can say that that the prevention, detection and the treatment of the cause of premature death and the blindness in infants is now and overall and a holistic approach for the care of infants that are premature and there is an ongoing evaluation and also the efforts that are being made inorder to the get ways and also the cares for the newborn.
The distribution of disease and biological plausibility play in suggesting the hypothesis that supplemental oxygen causes infant blindness is :
-Supplemental Oxygen.
Distribution of DiseaseThe distribution of disease and biological plausibility play in suggesting the hypothesis causes infant blindness is supplemental Oxygen.
The oxygen provided from exterior which is essential for certain people as the title recommends is required as a result of inaccessibility of oxygen inside and as well coming about in failure or trouble to breathe and this is often the term commonly utilized for Oxygen Therapy.
Biological credibility is an necessarily and essential tool and the foundation of relationship could be a means of causing any theory that has been shaped and the availability of oxygen that's inside causing failure of trouble in breathing and typically the common term utilized for Oxygen Treatment.

Which process describes the function of the category of enzymes known as
DNA polymerases?
A. Add new nucleotides to a strand and repair any errors
B. Unwind the double helix of DNA
C. Separate the complementary strands of DNA
D. Bond together groups of nucleotides on the lagging strand
Answer:
The process that describes the function of DNA polymerase is add new nucleotides to a strand and repair any errors (option A).
Explanation:
In the context of DNA replication, a complementary strand must be formed using an existing strand as a mold. This replication process is facilitated by the enzyme DNA polymerase, which is responsible for binding complementary nucleotides to the new strand, following the sequence of the original strand.
Additionally, this polymerase can correct or repair any error in the base sequence —together with its exonuclease activity— guaranteeing the integrity of the genetic information contained in the DNA and avoiding possible mutations.
The other options are not correct because:
B. Unwinding the DNA double helix or separating the complementary DNA strands is done by the enzymes topoisomerases and heliases.
D. Bonding together groups of nucleotides on the lagging strand is done by ligase enzymes.
A is correct; add new nucleotides to a strand and repair any errors.

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X
objective by raising the oil objective a little to avoid the damage to objective lens. Critique his
technique.
Please
Answer:
The observed image will not be sharp
Explanation:
When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).

Explain the relationship between surface area
and cell size and why it is important for cell sizes
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
Explanation:
The relationship between surface area and cell size is important to the cell because it determines how materials are exchanged in the cell, such as which materials go out and which come in, based on this ratio.
What is the significance of the cell surface area?The relationship between surface area and cell size is important because cells exchange materials with their surroundings based on it, for example, when the cell size increases, the volume of the cell increases more than the surface area, which decreases the ratio of surface area to volume and allows less substance to exchange through the cell, and vice versa.
Hence, the relationship between surface area and cell size is important to the cell because it determines how materials are exchanged in the cell, such as which materials go out and which come in, based on this ratio.

Explanation:
The free energy released by ATP hydrolysis can be used to drive endergonic reactions, such as the conversion of glutamic acid to glutamine. As you saw in the video, the synthesis of glutamine from glutamic acid is a two-step process: 1. ATP phosphorylates glutamic acid. 2. Ammonia displaces the phosphate group, forming glutamine. How does the phosphorylation of glutamic acid (Glu) provide energy for the rest of the reaction to occur? A. The addition of a phosphate to Glu forms ADP, which is then hydrolyzed, releasing energy for the reaction.B. The addition of a phosphate to Glu breaks apart a water molecule, and the oxygen is burned for energy for the reaction. C. The addition of a phosphate to Glu forms a phosphorylated intermediate with more free energy than Glu. The ammonia can thus displace the phosphate in an exergonic reaction. D. The addition of a phosphate to Glu forms a phosphorylated intermediate with less free energy than Glu. The ammonia can thus displace the phosphate in an endergonic reaction.
Answer:
C. The addition of a phosphate to Glu forms a phosphorylated intermediate with more free energy than Glu. The ammonia can thus displace the phosphate in an exergonic reaction.
Explanation:
The synthesis of glutamine from glutamic acid is a two-step process catalyzed by the enzyme glutamine synthetase.
In the first step, ATP is hydrolysed into ADP and a phosphate group which is transferred to the glutamic acid to form an acyl-phosphate intermediate, γ-glutamyl phosphate, thereby raising its free-energy content.
In the second step, the acyl-phosphate intermediate, γ-glutamyl phosphate, reacts with ammonia which displaces the phosphate group in an exergonic reaction.
