If you had a patient stool sample and wanted to look for pathogens, what would be the best plate to use for that application?
A. Mannitol Salt
b. EMB
C. CNA
D. MacConkey
Which one ?
If you have a patient stool sample and want to test it for pathogens, you would use a MacConkey plate. Option D is correct.
An agar plate is a petri dish used to cultivate bacteria. Most of these plates have growth mediums used to promote bacterial growth to allow further study. Each kind of plate is unique in the additives it has and the function they offer. Some contain dyes to detect certain organisms or substances while others contain antibiotics or inhibitors to control growth.
The mannitol salt plate is used to measure and compare bacterial growth in the presence of different substances. These plates are often divided into thirds and used to study growth in three different mediums.
The EMB plate contains specialized dyes. The E standards for Eosin, a popular microbiology dye used to better detect certain cells. This plate uses a mixture of this and a popular blue methyl dye. As with option B, CNA is also a plate with a popular kind of dye, but neither of these is capable of detecting pathogen agents.
To detect pathogens, you would use a MacConkey plate. This plate contains selective and differential mediums, used to detect valid factors. This plate can detect Enterobacteria. These bacteria can at times be harmless but are often the main cause of pathogens.

Some molecules are unable to enter cells by diffusion, and instead, must use active transport. How is diffusion different from active transport?
Answer: See Below
Explanation:
Diffusion is considered passive transport because it does not require energy to move molecules across the membrane. This is possible because of difference in concentration gradient. Molecules will flow from a higher concentration to a lower in order to make uniform concentrations, this is a natural process that does not require energy.
Active transport requires energy, typically in the form of ATP to transport molecules against a concentration gradient.

Which factors changed throughout the experiment? Check all that apply
In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.
The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.
The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.
As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.

Bessel's Star (61 Cygni) was the first star whose distance was calculated using the parallex method. The star is known to make an angle of 570 milliarcseconds between two opposite points of the Earth's orbit. Using this information, calculate the distance to the star.
Answer:
The parallax formula states that the distance to a star is equal to 1 divided by the parallax angle, p, where p is measured in arc-seconds, and d is parsecs.
d = 1/p
Explanation:
Parallax is a method of using two points of observation to measure the distance to an object by observing how it appears to move against a background. One way to understand parallax is to look at a nearby object and note its position against a wall. If you look with just one eye, then the other, the object will appear to move against the background.
Because your eyes are separated by several centimeters, each eye has a different perspective of where the object is relative to the background. The closer the object is, the more it appears to move relative to the background. This is true in astronomy as well, but on a much larger scale.
In astronomy, the distances to other stars is too great to measure using two objects on the Earth's surface. Lucky for us, the Earth itself moves. If we made two observations of the same star on opposite sides of the Earth's orbit, we would have a separation of 2 astronomical units, or AU. One AU is the average distance from the Sun to the Earth.
This is enough to get a noticeable angle, α, between the star's two apparent locations. In the image above, we can see that by cutting α in half, we get a right triangle where one leg is the distance between the sun and the other star. Lets let 1/2α=p. We can use tan p to find the distance to that star.
tan p = 1AU/p
Since the star will be very far away, we can make the assumption that
tan p is about equal to p. That simplifies our parallax formula to;
p = 1AU/d , or in other words, d = 1AU/p
Astronomical units are not the most convenient units to work with, though, so instead we define a parsec to be the distance to a star that shows 1 arc-second of parallax angle. Our formula then becomes;
d = 1/p parsecs
ANSWER:
!!Where p is measured in arc-seconds. 1 parsec is about 3.3 light years.!!

The white cat is the recessive allele w, while the black cat is the dominant allele B. However, in the f1 generation, the dominant allele concealed the recessive features, but they are heterologous dominant, i.e. BBww in f2 second filial generation: Bw x Bw.
There are three black kittens and one white kitten when f2 second filial generation offspring are crosslets. Consider the genotype of white cat WW and black cat as BB in the first generation as it's given in question all the offspring of f1 generation are black giving a hint that black is dominant over white.
Now genotype of f1 offspring is wB now in the second filial generation where 2 offspring of f1 crossed the resultant offspring is 3 black kittens and 1 white kitten. second filial generation is the second filial generation of the offspring produced by inbreeding F1 people, whereas F1 generation refers to the first filial generation of the offspring from the parents. hence, the results are BB, Bw, Bw, and ww.
