Which statement best describes how cell theory relates to a stem cell's ability to
change into specialized cell types?
The stem cells have the unique ability to undergo cellular differentiation which results into formation of a more specialized cell type which performs a unique function in body. Such as blood cells, neurons, etc.
What is Cell theory?
Cell theory has been proposed which describes various properties of a cell and how these cells develop. The theory has given some postulates and one of these postulates is that the new cells originate from pre-existing cells. Thus, the cell theory explains that the specialized cells which are present in body are synthesized from the stem cells.
Under the favorable conditions, the stem cells divide to form specialized daughter cells. These daughter cells become either a new stem cell or the specialized cells with a more specific function which includes blood cells, neurons, muscle cells or bone cells.

A black chicken and a white chicken are crossed. What is the probability that they will have erminette chicks?
Answer:
[tex]Probability = 100\%[/tex]
Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:
[tex]\begin{array}{ccc}{} & {B} & {B} & {W} & {BW} & {BW} & {W} & {BW} & {BW}\ \end{array}[/tex]
The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:
[tex]Probability = \frac{4}{4}[/tex]
[tex]Probability = 1[/tex]
Represent as percentage:
[tex]Probability = 100\%[/tex]

A 35-year-old woman comes to her dentist complaining of tenderness and pain in her cheek near the parotid gland, as well as bad breath and a foul-tasting mouth at meal times. A radiopaque fluid is injected into the parotid duct system through cannulation, and this sialography of the parotid duct confirms blockage by a calculus (sialolith). What muscle, through which the parotid duct passes, is most likely causing the stenosis where the sialolith now resides, blocking the drainage of the parotid duct

When identifying the agent responsible for causing a disease, why is evaluation of colony morphology not enough?
Answer:
Some infectious diseases are distinctive enough to be identified clinically. ... Infections may be caused by bacteria, viruses, fungi, and parasites. ... Microbial Identification: Colony and cellular morphology may permit preliminary ... Diagnostic medical microbiology is the discipline that identifies etiologic agents of disease.
Explanation:
Microorganisms have antigens present on their surface, Antigen tests detect the presence of a microorganism directly so that doctors can diagnose an infection quickly, without waiting for a person to produce antibodies in response to the microorganism.
Evaluation of colony morphology is not enough as it is not a definitive test. colonies of different bacteria can look the same, so it can help narrow.
What is antigen tests?An antigen test is an immunoassays test used for the detection of a specific viral antigen that indicates current viral infections.
Hence, Antigen tests detect the presence of a microorganism whereas, Evaluation of colony morphology is not enough as it is not a definitive test.

In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to produce a heterozygous F1 generation. Two F1 individuals are mated, and you do not see a 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio of offspring, but instead see that almost all offspring are a non-recombinant phenotype. This tells you that
Answer:
Epistasis effect result into these offspring
Explanation:
Given
spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b)
Genotype of true-breeding black spotted rabbit BBSS
Genotype of true-breeding brown solid rabbit bbss
Genotype of offspring BbSs
In normal crossing between BbSs and BbSs offspring of F1, should produce offspring in the ratio 9:3:3:1
But it does not happens in this case the simple reason could be presence of Epistasis in which the alleles assort independently but do not express themselves because of the following reasons -
a) Interaction between two or more loci thereby resulting into new phenotypes
b) An allele at one locus masks effects of other allele at one or more loci
c) Allele at one locus modifies the effects of alleles at one or more other loci

Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?
A. The insect develops slightly shorter or longer abdominal legs.
B. The insect develops normal body parts at either a slower or more rapid rate.
C. The insect develops normal body parts but in an altered time sequence.
D. The insect develops legs in other parts of its body.
Answer:
D. The insect develops legs in other parts of its body.
Explanation:
HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.

Water reacts with minerals in some rocks and very slowly dissolves the rock. What type of weathering does this demonstrate?
Answer:
Salt wedging
Explanation:
Salt wedging is a natural phenomenon which occurs in rocks and stones. It is a physical weathering process. It is a process by which water enters into the small cracks on the rocks and form salt like NaCl and thereby enlarging the cracks.
Most water contains dissolved salts and when water enters into the small cracks of the rocks, the salt begins to grow and it exerts pressures on the walls of the crack thereby enlarging the cracks.
This type of phenomenon is mostly seen near the seacoast and in the arid regions.
Thus water reacts with the minerals in the rock and slowly dissolves the rock in salt wedging weathering process.

Some flowers show incomplete dominance. If RR = white and R'R' = red, which phenotypic ratio would
be expected in the o spring of two pink flowers?
Answer:
1 red: 2 pink: 1 white
0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).
What is Phenotypic ratio?Phenotypic ratio defined as the relative number of offspring expressing a particular trait or combination of traits, which can be determined by performing a test cross and the frequency of the trait or trait combinations being expressed depending on the genotype of the offspring can be identified.
Phenotypic ratio is expressed as the ratio of different phenotypes present in the progeny of a cross where the ratios are numerical comparisons. For example, if one has three mangoes and two oranges, the ratio of mangoes to oranges will be 3:2.
For above given information, if we cross RR which is white with R'R' which is red, we will get 4RR' offspring which are pink in color. then the ratio will be 0 red: 4 pink: 0 white.
Thus, 0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).

B. False
Answer:
A. True
Explanation:
flow off a hill slope directly to a stream in the form of runoff, or it may flows downward through the unsaturated zone to reach the water table. The area at the stream or lake to which the groundwater is flowing. Recall that water is flowing in pores where there is friction, which means it takes work to move the water.

Explanation:
The lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In some interactions between lysogenic phages and bacteria, the lysogenic conversion may occur, which can also be called phage conversion.
