Xylem tissue that should help you out
<span>The answer is D) atmosphere. There are four spheres of the Earth: 1. Lithosphere (from Greek word 'lithos' = rock), 2. Hydrosphere (from Greek word 'hydros' = water), 3. Biosphere (from Greek word 'bios' = life), and 4. Atmosphere (from Greek word 'atmos' = air). Condensation is the change of water vapour into the water, i.e. the change of water from its gaseous form into liquid form. Since water vapour is the part of air, condensation occur in the atmosphere.</span>
Petri dishes should always be stored inverted.
In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.
Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.
