Answer:
Chemicals causing respiratory tract, eye and skin irritation.
Potential Carcinogenic chemicals
Explanation:
b-galactosidase is an enzyme encoded by Lac Z gene of the lac operon in E. coli. It hydrolyses b-galactosides and lactose into monosaccharides which are simple sugars
In order to carry out this assay, materials including b-mercaptoethanol and ONPG(o-nitrophenyl-b-d-galactopyranoside) are used.
b-Mercaptoethanol produces vapors which can cause respiratory tract irritation if inhaled and ONPG is a potential carcinogenic chemical.
Answer:
photosynthesis allows plants to make their own nutrients/food
Explanation:
photosynthesis is the process where plants make their own glucose so that they get ATP (energy) from the nutrients which allows them to grow. The chloroplast is the organelle where photosynthesis occurs, so it allows the process to happen.
Sunlight and h20 and co2 are present
Tge chloroplast which contains the grana and the stroma
Lewis Nixon invented the first sonar-like listening device to detect icebergs. During World War I (1914-18), a need to detect submarines increased interest in sonar. The U.S. military began using the term "sonar" during World War II.
