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 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.

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.

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.
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

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.
