Answer:
Fungi can be divided into two broad groups, called ascomycetes and basidiomycetes, depending on how their sexual spores are formed.
Photosynthesis means that the plant is able to use carbon dioxide (CO2), water (H2O), and sunlight to create food for itself.
This food is called glucose, which is a type of sugar. Oxygen (O2) is also created during photosynthesis.
Answer:
A. To cause intact DNA to precipitate, so the activity of DNase can be determined.
Explanation:
The presence of DNase is special feature for some species of bacteria and can be used for identifying them. During DNase test, diluted hydrochloric acid (HCl) can be poured onto the agar plates so that there will be a clear zone close to the bacteria colonies. Each nucleotides are soluble in diluted HCl. But DNA is not soluble in the diluted HCl, thereby making the DNA to precipitate in the rest of the plate.
