The test tube will be most likely the one with yellowish color.
This happen because of the respiration process between the snail and Elodea. Actually, this will heavily affected by the control factors. The more elodea that exist in the incubation, the lower the amount of CO2 would be,

hope this helps

As described in "A Note About Bacterial Reproduction -- and the "Culture Bias,"" the organism Epulopiscium does not divide by bi
gayaneshka [121]

In liquid media or broth difference between dry and wet will give biomass of the Epulopiscium.

Explanation:

Biomass of bacteria can be measured by dry or wet mass. Bacteria numbers can be counted by spread plate method under the microscope.

In solid media the colonies obtained are diluted and number of cells will be seen by plate count method or on automated cell counter. The number would help calculate biomass

The biomass will be calculated by measuring wet and dry mass. Equipments required will be:

hydraulic gravity convection oven and centrifugation set up.

A cellulose acetate filter membrane is used which is 47 mm in diameter and 0.45 micron of pore size.

The cells  grown settles down due to gravity. They are stirred to evenly spread in the broth and is kept in centrifuge.

The cells obtained after centrifugation will be taken and wet weight is obtained.

To obtain dry weight the cells are placed in oven for 6 hours to 24 hours. The resultant cells are weighed and dry weight obtained.

Biomass will be calculated by subtracting the wet mass to dry mass. This way biomass is obtained in epulopisicuium. Here the cells will be of different size so on centrifugation 2 or more phases of cells can be seen due to gravity change.

Prokaryotes have their chromosomes located in an area called the nucleoid.<br> a. True<br> b. False
g100num [7]

Answer:

True

Explanation:

Unlike eukaryotic cells, which have a nucleus that contains the genome and is separated from the cytoplasm by a membrane, the prokaryotic nucleoid is not membrane-bound and is not considered an organelle. The nucleoid is simply the area within a prokaryiotic cell where its DNA is located.
