What are some similarities and differences between SEM and TEM microscopes

1 answer:

7 0

SEM and TEM are electron microscopes whereas the SEM uses reflected electrons and TEM uses transmitted electrons to form an image

Explanation:

SEM is the scanning electron microscopes and TEM is the Transmission electron microscope

SEM works by detecting the scattered electrons to create an image of the sample whereas the TEM detects the transmitted electrons to create the image of the sample

SEM will only be analysing the surface of the sample whereas TEM collects data vertically also

TEM sample needs to cut thinner than SEM and TEM will give high-resolution images than SEM

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt wat

White raven [17]

Answer:

See the answer below

Explanation:

<em>The advice I would give to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.</em>

If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.

If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

The following figure shows a plant cell immediately after it has been placed in distilled water (A) and a plant cell that has be

DENIUS [597]

Answer:

Plant cell A has lower water potential than cell B. True

Plant cell B is isotonic to the fluid in the beaker. True

Plant cell B's water potential increased due to an increase in solutes inside the cell. False

Plant cell B is at equilibrium with the fluid in the beaker. True

Plant cell A has higher water potential than cell B. False

Plant cell A is at equilibrium with the fluid in beaker. False

Explanation:

Plant cell A has lower water potential than cell B. True

This statement is true because the water potential of A is -2 bars while that of B is zero bars.

Plant cell B is isotonic to the fluid in the beaker. = True

Isotonic solutions have equal water potential. Since the water potential of distilled water is zero and that of plant cell B is zero as well, plant cell B is isotonic to the fluid in the beaker.

Plant cell B's water potential increased due to an increase in solutes inside the cell = False.

An increase in solute inside the cell doe not increase water potential but rather reduces it.

Plant cell B is at equilibrium with the fluid in the beaker. = True

Plant cell B is at equilibrium with the fluid in the beaker because its water potential is zero since the negative solute potential is counterbalanced by the positive pressure potential.

Plant cell A has higher water potential than cell B = False.

Plant cell A has a lower water potential of -2 bars while plant cell B has a higher water potential of zero.

Plant cell A is at equilibrium with the fluid in beaker. = False.

Plant cell A is not at equilibrium with the fluid in the beaker, rather due to its negative water potential, water will move into the cell.
