8. S
h. Metaphase
Answers
The cell cycle in the correct order is G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
What is the cell cycle?Prophase, metaphase, anaphase, and telophase are the four phases that a cell goes through. To form chromosomes, chromatin condenses (sister chromatids joined at the centromere).
In prophase, the chromosomes get shorter and thicker, in the center of the cell, during the metaphase, the chromosomes align. Chromatids separate during the anaphase process and travel to the opposing poles.
Telophase: Two nuclei are produced when nuclear envelopes have reformed around each chromosomal group.
Therefore, the cell spends the majority of its time in interphase, which is also when it grows, duplicates its chromosomes, and gets ready to divide.

Coin tosses can demonstrate the effects of genetic drift. Imagine that heads and tails are two alleles in a population. Consider each coin toss to represent a member of the population. Write down the statements that describes the effect.
Answers
Answer:
Smaller populations have a greater chance of having one allele expressed disproportionately.
Explanation:
Genetic drift is defined as the a change in how frequently a gene allele occurs in a given population as a result of random sampling.
This random sampling is similar to having a coin toss that gives heads or tails.
Genetic drift has the tendency of making smaller populations have a greater chance of having one allele expressed disproportionately.
This is because when individuals in a small population mate there is a greater probability that an evolution will have more far reaching effects.
In a large population the effect will be less pronounced.
In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss).

Unstained cells have very little contrast. What single adjustment could you make to your microscope that would make cells easier to see at the same time while reducing the evaporation of your sample?
Answers
Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.

Which statements describe functions of antibodies? Select two options.
Answers
Answer:
This question lacks options, options are:
A.They maintain the cell’s shape.
B.They regulate cell processes.
C.They protect the body from infectious agents.
D.They signal the immune system to destroy pathogens.
E.They speed up biochemical reactions.
F.They send electrical signals.
The correct answers are C and D.
Explanation:
B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.
Search online to find at least two articles that have opposite opinions on the repeated breeding of pedigree dogs. Does one article seem more scientifically credible than the other? Explain your answer.
Answers
Answer and Explanation:
In current years the subject of inherited disorders in pedigree dogs has been extensively discussed. This article discussed the consequences related to repeat breeding of pedigree dogs. In the last few years several pedigree breeds have been generated which depend on the selection of particular behavioral and physical features. The development of pedigree dog breeds can be both a curse and a blessing. The desired characteristics are severely taken, while undesired characteristics can be unintentionally secure within the breed. The repeated breeding of purebred dogs lead the loss of genetic diversity. The loss of genetic diversity can be attributed to two major actions; the first one happening in domestication and the second arising from the development of breed. Where the repeated use of line breeding, popular sires, promotion of breed barrier rule and breeding for particular phenotypic traits contributed to loss of genetic variation. Widespread use of a popular sires leads to overrepresentation of that dog’s genome in breed. Overrepresentation of a popular sires genome increase the risk of monogenetic inherited disorders. According to the other article inbreeding causes severe birth abnormalities and defects such as epilepsy, and heart diseases that could make the lives of animals miserable. These problems start in the 19th century, when dog fanciers activated to set down desired physical characteristics. The scientific evidence shows that ninety percent dogs are said to be healthy. According to the both articles repeated breeding of pedigree dogs cause many genetic disorders.
Answer:
A veterinarian wrote an article stating his disapproval of some of the tactics used to breed pedigree dogs. He stated that pedigree dogs can be healthy, but because of inbreeding, they’re more likely to have health problems than other dogs. The author supported his statement with scientific studies.
A breeder with 20 years of experience wrote an article that was pro-breeding. He talked about his own success and shared his opinions on proper breeding techniques. Because the veterinarian used scientific facts to support his reasoning, his article seemed more scientifically credible to me.

Answer:
Urine refrigeration preservation maintains the sample in the ACS chemical analysis, cellularity and bacteriuria
Explanation:
Tests with high diagnosis and prognostic importance in clinical practice include urinary irregular constituents and sediment (ACS). If it is not possible to analyze ACS within two hours of processing, the sample must be retained to prevent pre-analytical interferences. Cooling is due to its economic productivity the most commonly used technique. In comparison, relative to chemical preservation, it poses fewer discomforts.

Please read the following scenario to answer the following question. While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, the researcher isolated and cultured a single cell from this group and noticed that the progeny of this cell were not producing a certain protein, and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ________
Answers
Answer:
deletion or insertion of nucleotide from or in any coding sequence of the DNA
Explanation:
The mutation would be most harmful to the cells if it resulted in the deletion or insertion of nucleotide from or in any coding sequence of the DNA.
Deletion or insertion of a nucleotide from/into the coding sequence of DNA results in a frameshift mutation away from the original protein. Deletion/insertion of a nucleotide from/to the coding sequence of a DNA can cause a totally different protein to be synthesized from such DNA or, worse still, results in a nonfunctional protein. Both results could be grossly harmful to the cells.
