Genetic drift says it is a random selection of a genetic variant that causing a change in allele frequency in a population.
One of the best treatment centers for Spinal Muscular Atrophy is located in North Dakota causing migration of SMA carriers into the area at an abnormally high frequency. Thus option B is correct.
What is spinal muscular atrophy?It is a group of autosomal recessive inherited disorders cause progressive muscle degeneration and weakness. One of the second leading neuromuscular disease.
Three types of SMA affect only children of less than 1 year and , type IV and Finkel type observed in adult, Symptoms in adult include weakness in muscles, tremor etc.
Type 1 SMA seen during birth symptoms include difficulty breathing and swallowing, Type II show muscle weakness between ages 6 and 12 months, Type III is juvenile type unable to stand and walk.
Type IV causes muscle weakness, tremor and twitching.

g DNA polymerase is used in PCR to cut DNA sequences into fragments that can then be inserted into vectors. true of false
Answer:
False
Explanation:
The answer is False.
The DNA polymerase is an enzyme that adds nucleotide bases to the growing chain during the elongation process of DNA replication. It is also utilized in the Polymerase Chain Reaction process to synthesize and amplify the DNA of interest.
Polymerase Chain Reaction is primarily carried out to amplify a DNA of interest in order to be able to study it in careful detail. Cutting of DNA into fragments is carried out by restriction enzyme and this is only done during genetic engineering when a foreign gene is to be inserted into a genome.

Glycans are a virulence factor for which group of organisms?
A. fungi
B. viruses
C. bacteria
D. protozoa
E. helminths
Answer:
C.bacteriaExplanation:
because bacterial glycans are attractive pathogen-specific targets. Bacterial cells are coated with an impressive array of glycan structures that comprise their cell wall
Glycans are a virulence factor for bacteria. So, the correct option is C.
What are Glycans?
Glycans are also known as polysaccharides, are carbohydrate-based polymers made by all living organisms. They are basically chain-like structures that are composed of single sugar molecules (monosaccharides) linked together by chemical bonds.
Now, out of given organisms, only bacterial cell walls are mainly composed of polysaccharides. So, these glycans sites are target sites for disease-causing agents to perform their activity.
Therefore, glycans are a virulence factor for bacteria.

If someone asked you whether people can be left-brained or right-brained, how might you respond based on what you learned in this activity?
Answer:
if they write by left hand so they are right brained.
if they write by right hand so they are left brained.
or, the theory is that people are either left-brained or right-brained, meaning that one side of their brain is dominant. If you're mostly analytical and methodical in your thinking, you're said to be left-brained. If you tend to be more creative or artistic, you're thought to be right-brained.
Explanation:
because the right brain is control the left hand

Which of the following BEST describes the template DNA for the positive control PCR tube in our Wolbachia PCR?
a. The positive control tube receives each kind of template DNA: genomic DNAs from insects known to be and predicted to be positive and negative for Wolbachia infection.
b. The positive control tube receives genomic DNA from an insect known to be positive for Wolbachia infection.
c. The positive control tube receives any genomic DNA from a student's sample that is predicted to be infected with Wolbachia.
d. The positive control tube receives water for template DNA.
Answer: c. The positive control tube receives any genomic DNA from a student's sample that is predicted to be infected with Wolbachia.
Explanation:
Positive PCR control can be defined as the control sample that is used as a benchmark for comparison with the results of the PCR or polymerase chain reaction. It comprises of artificial genome or primers. For amplification of microbial DNA synthetic oligonucleotides are used as targets of each primer and a hydrolysis probe is also used. As it is already known that primer as well as hydrolysis probe has the specificity for the DNA strand so it will help in identification of the specific region or sequence in the DNA structure. Wolbachia DNA can be detected if the positive control consists of samples of students affected by Wolbachia that can give indication of whether the Wolbachia species is the same as that of the one which has caused infection.

Which things need to be present for natural selection to take place? (select all that apply)
A.Variation in the population.
B.The ability for asexual reproduction.
C. Competition between organisms.
D. Large amounts of resources.
Answer:
A & C
Explanation:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
YES - A) You must have variation in the population, typically in the terms of "fitness" or having admirable/sucessful traits that make them more likely to reproduce and ensure their own offspring are fit too.
NO - B) It is sexual (not asexual) reproduction that uses natural selection for their offspring. Although some asexual organisms use natural selection, it is ALWAYS used if possible with natural selection to ensure the fitness of characteristics is passed down.
YES - C) Competition is necessary for natural selection to occur. When those who are more physically fit compete, they are more likely to live against their opponent and therefore pass on the trait of fitness.
NO - D) Although resources are necessary, large amounts are not as it does not lead to fighting over them (scarcity) bringing us back to the need for competition above.

how much can your bladder hold before it pops
Answer:
I posted a couple of pictures for you.
Answer:
Technically speaking, over 2 liters of urine (from patients in hospitals who come in after not having urinated for a week), before pressure causes it to rupture.
Explanation:
Why I say technically is because it is rather rare for someone to simply attempt to hold it until it bursts, this is usually a medical case. If you are not urinating and you're retaining urine, it can cause metabolic abnormalities and electrolyte issues, which can lead to long term kidney failure. A generally healthy bladder can hold between 400 - 500 ml comfortably it reaches it's intended capacity.
