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.

Anatomy is the branch of biology that deals with the study of the structure of organisms and their parts.
Biochemistry
Biochemistry is the branch of biology concerned with the chemical and physiochemical processes that occur within living organisms.
Biophysics
Biophysics is the science of the application of the laws of physics to biological phenomena.
Biotechnology
Biotechnology is the exploitation of biological processes such as genetic manipulation of micro-organisms for the production of antibiotics, hormones, etc.
Botany
Botany is the scientific study of plants, including their physiology, structure, genetics, and ecology.
Cell Biology
Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life.
Evolution
Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth (Darwinism)
Genetics
Genetics is the study of genes, genetic variation, and heredity in living organisms.
