Please find the definition of viscosity, effect of heat on DNA explanation to this question below
Explanation:
Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.
DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.
Viscosity refers to the 'thickness' or 'stickiness' of a fluid. Heat decreases the viscosity of DNA by providing energy to the molecules, which reduces the 'stickiness' between them. The underlying cause is changes in the interactions between the DNA molecules due to the heat energy overcoming the forces holding them together.
Viscosity is a property of a fluid that resists the force tending to cause the fluid to flow. In simple terms, it is the 'thickness' or 'stickiness' of a fluid. The greater the viscosity, the slower the fluid flows.
When exposed to heat, the viscosity of DNA decreases - it 'thins' and flows more easily. This happens because heat provides energy to the DNA molecules, increasing their movement and reducing the 'stickiness' between them.
The underlying cause of the change in viscosity due to heat is actually due to a change in the interactions between the DNA molecules. The added heat energy overcomes the forces holding the molecules close together, allowing them to move more freely relative to each other, thus decreasing the viscosity.
#SPJ3
was added to 9.9 ml of sterile buffer. After thorough mixing, this
suspension was further diluted by a 1/100 dilution followed by a
1/10 dilution. One-tenth of a ml of this final dilution was plated
on agar plates. After incubation, 52 colonies were present. How
many colony-forming units were present in the total 10 gram sample
of hamburger?
Answer:
5.2 × 10 ⁹ cfus
Explanation:
Using the dilution factors
0.1 ml of the final dilution has 52 colonies
1 ml will have approximately 520 colonies
10 ml of the final sample will have 5200 colonies
at 1 / 100 dilution
1 ml of the sample will have 5200 colonies
100 ml of the sample will have 520000 colonies
1 ml of the 0.1 ml + 9.9 ml has 520000 colonies
10 ml will have 5200000
at the second stage of the dilution
0.1 ml of the slurry had 5200000 colonies
1 ml will have 52000000 colonies
10 ml will have 520000000 colonies
100 ml of the initial sample ( 10 grams + 90 ml ) = 5200000000 colonies =
5.2 × 10 ⁹ cfu
