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.
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.

Which are the two agents that are necessary in the formation of metamorphic rocks? erosion and heat heat and lava lava and pressure pressure and heat
Answer:
Pressure and heat
Explanation:
Two agents that are necessary for the formation of metamorphic rocks are pressure and heat. The correct option is D.
What are metamorphic rocks?The secondary rocks known as metamorphic rocks are created when a rock changes as a result of shifting heat and pressure conditions. They come from sedimentary, igneous, or other metamorphic rocks, depending on the kind. Taking Quartzite, Marble, Schist, and Gneiss as examples.
When the sedimentary rock known as limestone experiences changes as a result of an increase in temperature and pressure, marble is created. Marble is frequently used to create monuments, paving stones, and sculptures.
When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.
Therefore, the correct option is D. pressure and heat.

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.

FAAAAAAAAAAAAAAAAAAAST!
Answer:
Lysosomes
Explanation:
Edge
The organelle is most likely malfunctioning in the patient’s cells is lysosomes. Thus, option B is correct.
What is lysosomes?
Lysosomes are the cell organelles that engulf or eat their own cells. Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
Therefore, the organelle is most likely malfunctioning in the patient’s cells is lysosomes. Thus, option B is correct.

How does population density differ from population size?
Answer:
population size can be any number from 1 to 1 million, but population density is how that population is squeezed into a specific amount of space. For example say you had 100 bunnies in a 100m by 100m area, your population density would be 1 bunny for every meter square
Explanation:
Population size can be any number from 1 to 1 million, but population density is how that population is located in a specific amount of space.
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 = _________

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 was removed and added to tube with 99 ml saline solution (tube 2). One ml suspension from tube 2 was played in MacConkey agar. After 24 h incubation, 30 red colonies and 50 colorless colonies were counted. Determine cfu/g Gram-negative bacteria in the fecal sample. Your answer must be in scientific notation such as 1.0 x 10^2. Round your answer to the nearest 10th. For example, your answer is 1.675 x 10^5 cfu/g, type 1.7 x 10^5 cfu/g. Put a space before and after the x. The x is lower case.
Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
Explanation:
We know that; Gram negative bacteria looks pale reddish in color under a light microscope from Gram staining.
therefore
There are 30 red bacterial colonies counted.
1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.
transferred volume into the plate is 1 mL.
Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample
Formula to calculate CFU/g bacteria in fecal sample is expressed as;
C = n/(s×d )
where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.
so we substitute
C = 30 / ((1/100) × 1)
C = 30 / 0.01
C = 3000
C = 3.0 × 10^3
THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
