33% is the unknown concentration of the tube.
Explanation:
Concentration of stock of windex = 50%
concentration of bacteria = 500 microliter
nutrient broth = 1000 micro litre +500 microlitre of windex
concentration of bacteria is the volume of bacteria present in nutrient broth culture.
total volume in the tube is 1000
50% is the concentration of tube of bacteria and broth before adding windex.
After adding windex of 50 % concentration and the volume is 500 microliter which is only 250 microliter of windex rest is water.
33% is the concentration of the tube, which means it has 33% of bacteria in 1500 ml of solution.
Answer:
B
Explanation:
Adaptation can be described as a process that helps the organisms fit their environment and enhancing their evolutionary fitness (reproductive success). Adaptation makes organism become well-suited for an environment and thus, help them to survive and produce more offspring. Also, adaptation may refer to a phenotypic or adaptive trait with a functional role in the success of each organism in their habitat.
They increase the genetic diversity of the species
the answer is decomposition.
