The bilayer is structured in such a way that it complements the extracellular fluid around the cell as well as the cytoplasm within the cell. This is because the extracellular fluid is hydrophillic, the outside of the membrane protein is hydrophillic, the middle of the membrane protein is hydrophobic, the inside of the cell (the cytoplasm) is hydrophillic and the inside of the membrane protein is hydrophillic.
Improper temperature control is one of the primary causes of illness or diseases as if the temperature is not set right, it could make bacteria grow or expand which is potentially harmful especially if they are to consume food-- if you food is contaminated with harmful bacteria because of improper temperature control, it could cause the food to be contaminated or spoiled, when consumed, it could led the person to have food poisoning.
Answer:
Used the C1V1 = C2V2 method for calculations
Explanation:
Component Calculation Volume of Stock to be added
FBS: 100*V1 = 10*25 2.5 mL
Glutamine: 200*V1 = 2*25 0.25 mL
Penicillin: 10000V1 = 100*25 0.25 mL
Streptomycin: 10000V1 = 100*25 0.25 mL
NB: C1 = Stock Concentration; V1 = Volume of stock required; C2 = Final concentration required; V2 = Final volume required
Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.
