Answer:
the same number of cells in both.
Explanation:
Nutrient broth is a general purpose medium that can be used to cultivate different variety of both fastidious and non-fastidious microorganisms.
Nutrient broth is known to contain or compose of simple peptone and a beef extract.
It is known to be used for bacteria that will not form colonies on a solid surface.
Nutrient broth can be prepared through this following steps
* Add 13g of nutrient broth powder in 1L of distilled water.
* Mix and dissolve them completely.
* Pour them into the final containers (eg. conical flask)
* Sterilize by autoclaving at 121°C for 15 minutes.
In this case, since the 100 ml and 1000 ml is prepared using the same method, it is expected to have the same number of cells in the same volume of the broth.
Different characteristics such as Earth's atmosphere, distance from the Sun, and presence of water make life on Earth possible.
<h3>Is there a groups of rules for organisms to live?</h3>
The idea that there is a group of rules to support life on Earth is controversial but it is clear that life as we know required different features to form.
Some of the most important features that support the emergence of biologically closed systems on Earth include the presence of water in a liquid state, an appropriate atmosphere and a suitable amount of solar radiation.
In conclusion, different characteristics such as Earth's atmosphere, distance from the Sun, and presence of water make life on Earth possible.

<span>Chromatids (either of the 2 chromosome strands that separate during mitosis) would not be fully developed.</span>
The EMB (Eosin Methylene Blue) agar is a selective and differential agar medium. It contains sucrose and lactose as fermentable substrates together with Eosin Y and methylene blue dyes which in combination gives the agar its characteristic color when prepared and serves as a pH indicator as well as an inhibitor of growth of Gram-positive bacteria. Hence, it is primarily used to isolate Gram-negative fecal coliforms while some positive fecal coliforms such as Staphylococci are also able to grow.
These coliforms are of two types:
- Lactose or sucrose fermenting coliforms form metallic sheens on the agar as a result of acid production and the response of the indicator to the increased acidity.
- Non-lactose/sucrose fermenters are only able to produce acid by protein deamination. Hence they either form colorless or pinkish colonies on the agar
On the other hand, Mannitol salt agar is a selective and differential agar medium that is primarily used to isolate Staphylococcal bacteria. The presence of sodium chloride in the medium makes it a partial or complete inhibitor of other bacteria.
Hence, an unknown bacterium that forms colorless colonies on EMB will either be a non-lactose fermenting, Gram-negative coliform that will hardly grow on Mannitol salt agar, or a Gram-positive fecal Staphylococcus.
Staphylococci bacteria are of two types:
- Coagulase-positive will form yellow colonies on the Mannitol salt agar.
- Coagulase-negative will form red colonies on the Mannitol salt agar.
