Lady bird [3.3K]

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.

1. Energy from the sun is transferred to Earth's surface. Some of that energy is then transferred to the air above the surface.

2. The closer a location is to the equator the more energy it receives from the sun. Therefore a location's air temperature is affected by its distance from the equator.
