Answer:

Plato Answer.

Explanation:

The pressurized seeds and spores have the ability to spread, helping the organism reproduce. In plants, it allows them to reduce competition by flinging the seeds far away so that their offspring don’t compete for resources. For the fungus, it allows the parent to fling the spores into the grass so that when the horse eats them, the life cycle of the fungus continues.

It is a beneficial adaptation since the pressurized seeds and spores spread widely, helping the organism reproduce elsewhere. In plants, it allows them to survive better by flinging the seeds far away so that their offspring don’t compete for food. For the fungus, it allows the parent to fling the spores into the grass so that when other animals eat them, the life cycle of the fungus continues on. These may be dispersed by the wind.

Answer:

Both electromagnetic and mechanical waves are the movement of energy. They can be measured in the same ways too. The amplitude, frequency, and wavelength are ways to represent the measurements of waves. Additionally, they both have crests and troughs. Finally, both can be reflected, absorbed, or transmitted.

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

Which of the following error ranges would be the most reliable with a study, all else being equal?

slamgirl [31]

<u>Answer:</u>

The error ranges would be the most reliable with a study, all else being equal is:

Option: A is correct.

A. ±6 percentage point.

<u>Step-by-step explanation:</u>

The error range such that the error range is most reliable in the study is:

±6 percentage points.

( Since for the solution to be most reliable the error must be small so that the value is close to the actual value and hence the study is reliable)

how could measure whether or not the chemical reaction that breaks down hydrogen peroxide is occurring

d1i1m1o1n [39]

Answer:

You could check the pH!

Explanation:

This is an idea, when you break down H2O2 (Hydrogen peroxide) you will be left with H2O (Water) and O2 (Oxygen gas). H2O2 theoretically would have a lower pH than water. Water has an average pH of around 7 while H2O2 will have a pH of about 4.5.

So theoretically to figure out if hydrogen peroxide is being broken down you can test for the pH. This is a very simply process, you just stick a little peice of litmus paper into the solution and immediatly it will change color to tell you the pH.
