You are the proud owner of a purebred herd of Pietrain pigs. Pietrain is a lean breed of pigs, but it has a high frequency of Porcine Stress Syndrome (PSS). PSS has a major locus that controls its presence. There may be several modifier loci that affect the degree of PSS, they only have an effect if the PSS allele is present. The pigs can be screened for the presence of the allele by exposure to halothane gas. Stress susceptible pigs become rigid. There is now also a DNA marker to test for the PSS gene. Genetic Model HH = normal Hh = normal hh = exhibit PSS (react to Halothane 1 pts a) You test 100 random pigs in your herd for the PSS gene. 10 of them react to the gas What are the allelic frequencies in you herd? p =frequency of H = _________ q = frequency of h = _________
Answer:

If you are pushing a box toward your friend with a force of 20 N, and your friend is pushing the box
toward you with a force of 30 N, what will happen to the box?
The box will move toward your friend with a force of 10N.
The box will move toward you with a force of 50 N.
The box will move toward you with a force of 10 N
The box will move toward your friend with a force of 50 N.
Answer:
The box will move toward you with a force of 10N
Explanation:
If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N
Which of the following are possible treatments for multiple sclerosis? There may be more than one correct answer. Which of the following are possible treatments for multiple sclerosis? There may be more than one correct answer. Increase the influx of positive ions through TRPV1 channels Stimulate the regeneration of myelin Decrease the threshold for voltage gated K+ channels at the axon hillock Block immune cells from crossing the blood brain barrier Increase acetylcholine release at the neuromuscular junction Increase the threshold for voltage gated Na+ channels at the axon hillock
Answer:
--Block immune cells from crossing the blood brain barrier.
--Stimulate the regeneration of myelin.
Explanation:
Multiple sclerosis or shortly known as MS is an unpredictable disease caused in the humans. Multiple sclerosis affects the central nervous system of our brain which causes the disruption in the flow of the information within our brain, and between our brain and the body.
It is a very rare disease.
The symptoms of MS may vary and includes double vision, weakness, fatigue, impaired coordination, pain, etc. Though there is no permanent cure for MS but scientist and doctors around the world suggest that by blocking the immune cells and stopping them from crossing our blood brain barrier can prevent this disease.
Multiple sclerosis can also be prevented by stimulating the myelin to regenerate.

The question bus incomplete, below is the complete question;
You need to determine which degradable material to use as a tissue engineering scaffold for repair of a critical-sized bone defect. (A critical-size defect is one that will not heal unaided.) You are planning to seed the scaffold with cells then implant it into the defect. While the cells proliferate and generate bone, the scaffold will degrade and create void space into which the new tissue may grow. What degradation method would you prefer for this scaffold material and why ?
(Hydrolytic vs Enzymatic degradation, Bulk vs Surface degradation).
The correct answer to the question is Degradation via Hydrolysis.
This Degradation via Hydrolysis will be most preferred and suitable in this application because,as a result of the aqueous environment between the patients, the lack of need for placing a target on the degradation areas (Since it is implanted into the site that has defect, it is accessible by water because it is already localized).
The bulk degradation of the scaffold will also be considered because since the overall dimensions will be consistent, over a given period of time.
But if the material underwent surface degradation, the implant could loosen up before there is sufficient tissue repair has developed or even fall out of the defect..
Or any cells that are seeded can equally detached itself from the scaffold.

What are oligosaccharides used for?
Answer:
Fructo-oligosaccharides are made up of plant sugars linked in chains. They are taken from asparagus, Jerusalem artichokes, and soybeans, or produced in the laboratory. People use these sugars to make medicine. Fructo-oligosaccharides are used for constipation, traveler's diarrhea, and high cholesterol levels.

What will happen when the 14 grams of protein in the Greek yogurt is eaten by person
Answer:
it gives energy.
Explanation:
If a person consumes 14 grams of protein present in the Greek yogurt, it gives high amount of energy because protein is a macromolecule which is needed by the human in large amount in order to maintain health of the body. This protein is broken down by a number of enzymes and converted into amino acids which is used in the growth of the body, formation and repairing of muscles.
When 14 grams of protein is consumed by a person ; The protein will be broken down into amino acids needed by the body to build up muscles and provide energy needed by the individual.
The Greek yoghurt is a type of yoghurt containing more protein and less sugar unlike other yoghurts therefore when you consume a Greek yoghurt you will be consuming a considerable amount of protein.
The protein consumed will be broken down in the body by enzymes into amino acids that will be absorbed into the body cells. these amino acids help in the repair and building of muscles. it is also a source of energy to the body.
Hence we can conclude that The protein will be broken down into amino acids needed by the body to build up muscles and provide energy needed by the individual.

People's choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual's health and, if applicable, the health of others.
Answer:
try eating foods that have a unique taste that may appeal to you but are still healthy
Explanation:
One positive choice someone can make would be drinking more water. One negative choice someone can make would be smoking too many cigarettes. Drinking more water can boost your health by decreasing chances of digestive problems and increasing blood pressure. Also, smoking too many cigarettes can lead to heart diseases, lung diseases, and diabetes.
What are the results of the cell cycle?
Answer:
Explanation:
The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. During inter phase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.
Answer:
The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages of growth, DNA replication, and division that produces two identical (clone) cells.

HeLP PLZZZ. How was the elasticity related to the bounciness of a ball?
Answer:
elasticity is the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.
For a ball to bounce, it must be made from materials with high elasticity so that they can maintain their shape instead of absorbing the impact of a toss, by changing shape. The elastic properties reduce the amount of deformity that comes from an impact, making it more effective at bouncing.
Explanation:
The bouncing of a ball mainly depends on two major factors one is the elasticity of the material of the ball and the other the force at which it is bound.
The elasticity is the ability of the material to resisting against distortion or change such as squeezing, stretching, and return to its original form again.
The elasticity is different for the different materials.Ruber is more elastic in comparison to metal, plastic, or marble.The ball bounce if dropped from a particular height due to its elastic property.When the ball hit the surface it squeezed and due to its elasticity, it returns to its original shape and rebound and bounce.Thus, the correct answer is - elasticity leads to an elastic collision and ball bounces.
