What do you think will happen to an egg after being in water for three days? Be sure to give a reason for your hypothesis.

I wouldn’t think anything would happen because the egg has a shell. I would imagine that the shell is unlike a cell membrane because its job is to not allow substances in. Accordingly, it would not have any properties of a cell membrane; low permeability and protein channels absent would mean that processes such as osmosis, diffusion, active transport wouldn’t be possible. Effectively, water can’t move in or out so the egg won’t shrink and shrivel up or swell and burst due to the movement of water out or into the egg (cell) respectively.

Most human cells range from 10 to 15 micrometers in diameter. What limits how large a cell can get

Mice21 [21]

The relationship between its volume and surface area limits how large a cell can get.

<h3>What is cell range?</h3>

The range of a cell is defined as the quantity of material that can be found within a cell with respect to the surface area.

The range of a cell is limited by the volume and the surface area which means that the wider the surface area the more volume the cell can contain.

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 wa

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
