Answer:

All of the above.

Explanation:

Light and Water both are among the ecological factors .
Ecological factors are those components of environment which determine the variation in the chemical and physical nature of different ecosystem.
A balanced ecosystem needs to have all its ecological factors in adequate amount.
Thus, too much water, too much light, not enough light or not enough water , any of these condition can upset the balance of ecosystem.

What is your favorite animal and why

Gre4nikov [31]

Answer:

My favorite animal is a cheetah. I have three reasons of liking the cheetah with consists of these fine abilities/skills/cool things. I like how the cheetah has a really pretty coat of spots and speckled with really makes it stand out and look different. I also like that the cheetah is lightning fast, but it's sad it can only run 60-70 miles per hour for a short period of time. I Also like that cheetahs can be in zoos and also can be trained, petted, and can also (rarely) have babies. Cheetahs need to be saved because they are starting to get really rare and endangered.

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
