What experiment is left overnight what would be the observation fresh potato in sugar solution and water

1 answer:

6 0

The potato would expand or it’s mass will increase bc there is more solute in the potato. The potato is placed into a hypotonic solution, thus the water will move into the potato.

Answer:

The correct option is lamprey.

Explanation:

Lamprey is a kind of fish which lack jaws. They lack a true skeleton, but the cartilage is present in them. Due to lack of proper backbone, they look similar to snails. The lamprey reproduces by laying eggs in the water. Larvae tend to develop from these eggs. The lamprey releases its eggs only in freshwater. Only the mature lamprey live in the sea to act as a parasite and take food. For laying eggs, it travels to freshwater.

Antimicrobial susceptibility testing was performed to screen a novel compound. The MIC was found to be 10ng/mL. Use the followin

Alinara [238K]

Answer:

a) Percent recovery

100%, 70.58%, 4.11%, 1.29% , 0%

b) MBC = 160 ng mL

c) Static

Explanation:

A) Calculate the percent recovery for each group

i) for 0ng mL

( 3.4*10^5 / 3.4*10^5 ) * 100 = 100%

ii) for 10ng mL

( (2.4 * 10^5) / (3.4 * 10^5) ) * 100 = 70.58%

iii) for 20ng mL

( ( 6.4 * 10^5 ) / ( 3.4 * 10^5 ) ) * 100 = Nil

iv) for 40 ng mL

( ( 1.4 * 10^4 ) / ( 3.4 * 10^5 ) ) * 100 = 4.11 %

v) for 80 ng mL

( ( 4.4 * 10^3 ) / ( 3.4 * 10^5 ) ) * 100 = 1.29%

vi) for 160 n mL

percentage recovery = 0%

B) what is the MBC

The value of MBC = 160 n mL because at this concentration CFU/mL = 0

c) determine if the antimicrobial tested is static or cidal

condition : If, the ratio of MBC : MIC is ≤4 then novel compound is Cidal

MBC / MIC = 160ng / 10ng = 16 : 1

hence we can conclude that the antimicrobial tested is STATIC

The law of superposition states that in horizontal rock layers, the oldest layers are at the bottom. Which statements

Anastaziya [24]

Answer:

It describes the order of rock layers.

It is a statement of fact.

Explanation:

Law is a statement that is found to be true and acquire from a number of experiments, while theory is gain from assumptions not through experimentation. Layers of soil never change their place with the passage of time. The oldest layer remains below at the end while the new layer is found on the surface of soil. It is a statement of fact because it is proved from experimentation. It never changes as the advancement of technology occurs.
