PLEASE HELP 50 POINTS!!!!Which of the following best describes the approximate number of cells in the culture that are in interphase, as well as the consequence of the severe disruption of interphase in mitotic division of cells within a tissue?
A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
B)There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
C)There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
D)There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.
Answer:
The correct answer is D, "there are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide."

Answer:
Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.

fernandes a, connors jm, carrier m. anticoagulation for subsegmental pulmonary embolism. n engl j med. 2019;381(12):1171-1174.
A pulmonary (lung) artery obstruction is referred to as an acute pulmonary embolism or embolus.
What can be diagnosis of acute pulmonary embolism?Acute pulmonary embolism (PE) causes 50,000 to 200,000 deaths per year and is a common cause of death. After coronary artery disease and stroke, it is the third most prevalent cause of mortality among cardiovascular diseases. The development of multi-detector computed tomographic pulmonary angiography (CTPA) has increased the rate of diagnosis of PE by enabling improved assessment of PE regarding imaging of the peripheral pulmonary arteries. As a result, more instances of accidental PE and isolated subsegmental PE (SSPE), two types of peripheral PE, have been discovered. Usually, patients with these two disorders have little to no evidence of the traditional PE symptoms, such as hemoptysis or pleuritic discomfort, abrupt dyspnea, or circulatory collapse.

monosaccharide profiling of glycoproteins by capillary electrophoresis with contactless conductivity detection
Monosaccharide profiling of glycoproteins by capillary electrophoresis with contactless conductivity detection is saccharides.
What are saccharides?Saccharides form one of the major constituents of the biological macromolecules in living organisms. Many biological processes including the protein folding, stability, immune response and receptor activation are regulated by glycosylation.
In this work, we optimized a capillary electrophoresis method with the capacitively coupled contactless conductivity detection for separation of eight monosaccharides commonly found in glycoproteins, namely D-glucose, D-galactose, D-mannose, N-acetyl-D-glucosamine, N-acetyl-D-galactosamine, D-fucose, N-acetylneuraminic acid, and D-xylose. A highly alkaline solution of 50 mM sodium hydroxide, 22.5 mM disodium phosphate, and 0.2 mM CTAB (pH 12.4) was used as background electrolyte in a 10 µm id capillary. To achieve baseline separation of all the analytes, a counter-directional pressure of –270 kPa was applied during the separation. The limits of the detection of our method were below 7 µg/ml (i.e., 1.5 pg or 1 mg/g protein) and the limits of quantification were below 22 µg/ml (i.e., 5 pg or 3 mg/g protein). As a proof of the concept of our methodology, we performed an analysis of monosaccharides released from fetuin glycoprotein by acid hydrolysis. The results show that, when combined with an appropriate pre-concentration technique, developed method can be used as a monosaccharide profiling tool in glyco-proteomics and complement the routinely used LC-MS/MS analysis.

The organelle here is lysosome as it collects the trash of the cell. The correct option is B.
What is a lysosome?A lysosome is a cell organelle that contains digestive enzymes and is membrane-bound.
Lysosomes are involved in a variety of cellular processes. They degrade extraneous or worn-out cell parts. They could be used to eliminate invading viruses and bacteria.
Lysosomes serve as the cell's digestive system, degrading material taken in from outside the cell as well as digesting obsolete components of the cell itself.
The lysosome's interior is acidic and contains numerous enzymes that break down molecules.
It is known as the cell's recycling center, but this does not imply that it only plays a passive role in the cell.
Thus, the correct option is B.

The correct answer is Ribosomes is the single molecule that could do both cellular work and replicate itself.
Ribosomes have two primary functions: message decoding and peptide bond formation. The ribosomal subunits are made up of two large ribonucleoprotein particles (RNPs) of unequal size. Each subunit is composed of one or more ribosomal RNAs (rRNAs) and a large number of ribosomal proteins (r-proteins). The ribosome is an ancient molecular fossil that can be used to peer into the origins of life. In all living systems, the ribosome, which is composed of RNA and protein, converts mRNA to coded protein. Translation is infused with universality, economy, centrality, and antiquity. Because the ribosome is so important to all aspects of life and reproduction in an organism, rapid change is unlikely to survive. The ribosome components are an excellent resource for studying the evolution of all organisms because all cellular organism have ribosomes .

I'm basically confused about the directions of this slide. Can someone help me?
If I am understanding correctly, the first thing they are asking you to do is match nitrogen bases.
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Then, whichever are the double strands, cut them out and put them into you notebook. (I am not sure where the notebook is, but I am assuming you know)
Then in the speech bubble next to the picture of Chargaff- talk about his rule.
What does the rule mean?
What does the rule explain?
How is the rule demonstrated?
Lastly, finding percents. What percent of the pairs has Adenine in them?
For example:
If I look at this pairing below
A →T
T→ A
G →C
C→ G
50% of the pairs include Adenine.
Hope I helped! Comment if you have questions about my answer :)
Answer:
If the sequence of nitrogenous bases of a DNA strand is ATCTAGGCCG, the complementary strand would be TAGATCCGGC, with a percentage of guanine 30%, cytosine 30%, adenine 20% and thymine 20%, according to Chargaff's rule.
Explanation:
DNA is made up of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one strand are matched with the bases of another, according to the complementarity of nitrogenous bases, where:
Adenine is complemented with Thymine A=T Guanine is complemented with Cytosine G≡CThe image shows a DNA chain whose chain is complementary:
DNA Strand given Complementary Strand
Adenine Thymine
Thymine Adenine
Cytosine Guanine
Thymine Adenine
Adenine Thymine
Guanine Cytosine
Guanine Cytosine
Cytosine Guanine
Cytosine Guanine
Guanine Cytosine
Therefore, in a DNA molecule there is as much adenine as thymine, and an equal amount of cytosine and guanine. In this example there are 4 molecules of adenine, 4 molecules of thymine, 6 guanines and 6 cytosines.
The proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff was able to establish that in a DNA molecule the ratio of purine:pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
Guanine 30%
Cytosine 30%
Adenine 20%
Thymine 20%
Total ..... 100%

Organisms that obtain their energy from producers or other consumers are heterotrophs.
What is heterotrophs ?An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy. Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition." Autotrophs and heterotrophs are two general classifications of organisms depending on how they receive energy and nutrients.
In contrast to heterotrophs, which cannot produce their own food and must rely on autotrophs for sustenance, autotrophs are organisms that create their own food through the process of photosynthesis.Humans and all other mammals, fish, birds, insects, and more basic living forms like bacteria and fungi are examples of heterotrophs.Learn more about Heterotrophs here:
