Answer:
8900 CFU/mL
Explanation:
Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.
UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.
Calculation
Colonies * Dilution = CFU/mL
89 * (100/ 1 mL) = CFU/mL
8900 CFU/mL
Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.
Answer: 5 prime cap
Shortly after RNA polymerase begins to transcribe a pre-mRNA, a 5 prime cap is added.
, Hope this helps :)
Have a great day!!
Answer: Option B) Nucleus
A threadlike genetic material called chromatin is located within the nucleus
Explanation:
Chromosomes are thread-like genetic materials that exist in pairs. However, they are called chromatid when single. Hence, two chromatids makes a chromosome. And chromosomes are located within the nucleus
This is called active transport. The proteins use ATP to transport stuff in and out of the cell.
