Answer:
According to the given question that without prior knowledge on the prodigiosin synthesis pathway of these Serratia species, and we experience two different color morphs of the species. So, there is given or known preliminary morphological basis we will consider them different two different colonies. These can be identify only after genetically identify or study.
The morphological characterstics of the organism and the genetic identification both are equally important. So Giving any one more importance over other is not logical.
Morphologically we can differentiate the color of the colonies of mutants. The mutant serratia sp. are known for eficient biosynthesis of prodigiosin, Thus on the basis of color characteristics of their colonies when grown on peptone glycerol medium we can identify.

A husband and wife have a child who suffers from cystic fibrosis (CF), an incurable, fatal hereditary disease that results in frequent infections and difficulty breathing. The couple wants to determine their risk of having another child with this disorder. Because CF is a recessive disorder, a child usually must inherit the CF gene from both parents to get the disease. A child with just one CF gene is a carrier: Such a person doesn't have the disorder 'but can pass the trait on to the next generation. The DNA test revealed that the mother of the child carried the CF trait; however, her husband did not. The DNA tests showed that he was not the biological father of the child.
This test has put the counselor in a difficult situation. Should the counselor tell the couple about the nonpaternity findings? Should the mother be told privately? If so, is the center colluding with the mother to withhold information from the husband? In addition, this case brings up issues concerning the biological father of the child. This man has not contracted with the genetics center for the test, yet the counselor now knows that this man is probably a carrier of the mutant gene for CF.
Required:
a. Should the genetic counselor call this man and tell him about his risk?
b. What would you do if you were the genetic counselor?
c. Present arguments for both sides of the issue.

By the early 1980s, the population of Florida panthers had dwindled to fewer than 30. Furthermore, within this population was a high frequency of detrimental traits, including low sperm count and undescended testicles in males, and kinked tails in both sexes. The future for this iconic population was bleak at best. Provide an explanation for the observed detrimental traits. Provide a possible solution that would both increase the likelihood that the population would survive and preserve the genetic identity of this unique population.
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
In the cell bio lab, we use company manufactured gels, however you can make you own polyacrylamide gels. List all of the ingredients found in an SDS-PAGE gel. Which ingredients are responsible for polymerizing the solution?
Answer:
The list of ingredients are used in this method are as follow-
1. Acrylamide - mostly 30%
2. Bisacrylamide - mostly 0.8%
3. 1.5M Tris-Hcl pH 6.8 for stacking gel and 8.8 for separating gel.
4. 10% SDS
5. 10% APS
6. TEMED
7. Double distilled water
Polymerization:
Acrylamide is a polymer that is used to dissolved in buffer and bisacrylamide is the cross linking agen.
Two types of gels are prepared for separation of protein. Stacking gel is usually 4 or 6% and separating gel is usually 10 to 20%. Lower concentration of stacking gel will allow the migration of all the protein same because of larger pore size. It will stack or line up the proteins for its next level of separation.
Higher concentration of separating gel will provide resistance to the movement of protein because of the low pore size and therefore linear bands can be achieved neatly.
Unlike skeletal muscle, the muscle cells of the heart (called "cardiomyocytes") metabolize very little glucose, relying almost exclusively on metabolism of fatty acids for their energy. Which of the following statements are likely to be true of cardiomyocytes, but NOT skeletal myocytes? (select two answers)
a. low levels of glycogen storage, even when blood glucose is high
b. high levels of glycogen storage, even when blood glucose is low
c. low lactate production, even at high activity
d. high lactate production, even at low activity
e. many mitochondria compared to other cells
f. few mitochondria compared to other cells
Answer: A. low levels of glycogen storage, even when blood glucose is high.
C. low lactate production, even at high activity.
Explanation:
Cardiomyocytes are also known as the myocardiocytes. They are the cells which makes up make up the muscle if the heart. They're responsible for the generation of the contractile force in the heart which helps in the pumping if blood.
From the options given, the statements that are likely to be true of cardiomyocytes, but not of skeletal myocytes include:
• low levels of glycogen storage, even when blood glucose is high.
• low lactate production, even at high activity.
Answer:
The answer is A and C
Explanation:
Since cardiomyocytes are dependent on fatty acids, they rely on oxidative phosphorylation to generate energy, and consume very little glucose. Due to this, they have very low need for fermentation of pyruvate. In fact, they can absorb lactate generated by skeletal myocytes and erythrocytes and oxidize it for additional energy. Another consequence of this metabolism is that cardiomyocytes store little or no glucose as glycogen.
Skeletal myocytes and cardiomyocytes both have high energy needs and thus have more mitochondria than other cells. Cardiomyocytes have an even greater density of mitochondria than skeletal myocytes because they depend almost entirely on oxidative phosphorylation for their energy needs. This dependence on oxidative phosphorylation also explains the extraordinary sensitivity of cardiac muscle to hypoxic (low-oxygen) events. Without oxygen, cardiomyocytes rapidly run out of energy and can quickly die.

g In order to stimulate the renin-angtiotensin-aldosterone system (RAAS), _______________ cells in the kidney detect _______________blood pressure which causes ________________ to be released from the juxtaglomerular cells.
Answer:
Macula densa cells, lower and renin.
Explanation:
Macula densa cells in the kidney detect lowers blood pressure which causes renin to be released from the juxtaglomerular cells which is an enzyme. The arterial cells observe the drop in blood pressure, and the decrease in Na concentration is transfer to them by the macula densa cells. The juxtaglomerular cells then release an enzyme called renin. Renin converts angiotensinogen which is a peptide, or amino acid derivative into angiotensin-1.

Answer:
Explanation:
A woman who is a carrier for #1 hemophilia and a man that does not have the condition have children. What is the probability that they will have a child with the condition being studied? What is the gender of that child?
if the baby gets the Y chromosome from the father it will be a boy. If the boy gets his mother's X chromosome with the hemophilia gene he will have hemophilia. If he inherits his mother's other X chromosome, he will have normal blood clotting. If the baby gets the X chromosome from the father it will be a girl.
#4 A woman that is heterozygous for type A blood and a man that is heterozygous for type B blood have children. What are the possible blood types of their children?
One parent with A and another with B can produce a child with A, B, AB or O blood types.
#5 Two people are both unknowingly carriers for the cystic fibrosis gene. What is the probability that they will have children with cystic fibrosis?
If both parents are carriers there is a 1 in 4 (25 percent) chance that both will pass on the non-functioning gene, which would result in a pregnancy affected with cystic fibrosis.
#3 A woman that is heterozygous for Huntington's disease and a man that does not have the condition have children . What is the probability that their children inherit the Huntington's gene ?
Huntington's disease (HD) is what is called a dominant genetic disease. What this usually means is that a child only has a chance of getting a disease like this if a parent has it too. But parents without HD can have a child with HD. This is true of any dominant genetic disease

b. Bobcats are another predator of snowshoe hare. If a population of bobcats immigrates to the
area, how is this likely to affect the habitat's carrying capacities for hare and lynx?
Answer:
Decrease population and carrying capacity.
Explanation:
If a population of bobcats immigrates to the area, the population of hare and lynx decreases that also affect the habitat's carrying capacities for hare and lynx because bobcats feed on both hare and lynx. Bobcats are very aggressive in nature, and has an aggressive hunting style. With these characteristics, the bobcats can hunt both hare and lynx which leads to decrease in population and carrying capacity.

4.In humans, the allele which confers the ability to roll the tongue is dominant over the allele which does not confer the ability to roll the tongue. If a man who can roll his tongue and whose mother could not mates with a woman who cannot roll her tongue, what proportion of the children would be expected to be able to roll their tongues if they have a large number of children
Answer:
The correct answer is - 1/2
Explanation:
the ability to roll the tongue is dominant over those who can not roll the tongue. The man is Rr (man), heterozygous. The woman is recessive and can not roll
Rr (man) x rr (woman)---Parents
r
R Rr (roll)
r rr (cann't roll)
The probability of their children to able to roll = 1/2 = 50%
plz give a correct answer for the question how do canine and molar differ
Answer:
Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food
Molars are the flat teeth at the rear of the mouth. Each molar typically has four or five cusps. They are used exclusively for crushing and grinding. Wisdom teeth are also called third molars. They erupt from the age of 18 onwards but are often surgically removed.Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.
