How does the plasma membrane of a cell compare with the membrane in the U-shaped tube?
Lilit [14]

Answer:

La membrana plasmática, también llamada membrana celular, se encuentra en todas las células y separa el interior de la célula del ambiente exterior. En bacterias y en células de plantas, hay también una pared celular que se une a la membrana plasmática en la superficie exterior. La membrana plasmática se compone de una bicapa lipidia que es semipermeable. La membrana plasmática regula el transporte de materiales que entran y salen de la célula.

Removes carbon from air: photosynthesis by plants and algae
Release of carbon into atmosphere: respiration (animals exhale CO2), factory emissions, eruption of volcanoes, hydrothermal vents, and breakdown of organic matter
Release of carbon into the soil: Shells of marine organisms form limestone, and some carbon from decomposing organisms is stored in the soil
*This isn’t every possible pathway but hopefully this will help get you started. I’m going to attach a picture of the carbon cycle (not mine) to help you visualize the process.

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
malfutka [58]

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
