A plant can open or close its stomata in response to environmental conditions. ... A. During a rainstorm, stomata can be opened to absorb additional water through osmosis. B. During a drought, stomata can be closed to prevent excessive water loss through transpiration.
The answer ; double, single
In unsaturated oils, the double bonds cause the hydrocarbon chains to have kinks hence do not allow adjacent hydrocarbon chains to form enough hydrogen bonds between each other. Therefore, chains are not compact enough even at low energetic levels (at room temperature).
In saturated oils, the single-bond hydrocarbon chains have numerous hydrogen bonds between adjacent chains that they become compact at room temperature (when their molecules have low energy levels)
Answer and Explanation:
Microscope objects have thermal profiles. These profiles differ as a purpose of their physical parameters. Most objects are sold and designed for the resolution of fixed cell microscopy.
There is little indication that the temperature cycle affects the strain characteristics. A large box can be constructed around the microscope and heated with hot air.
The heating system's cycling causes the specimen to drift out of focus and can also change the coverslip position.
The microscope can be equilibrated to a single temperature to eliminate the movement resulting from the thermal expansion of the microscope's components.
Air currents connecting the specimen chamber should also be reduced—tight control of temperature for the entire laboratory and microscope. Any change in the temperature can lead to unwanted movement in the microscope. Heating ducts often produce localized temperature changes.
Molds will develop on some of the samples.
Molds grow best in warm, dark and moist conditions.
In the first sample, the sealed bread should develop mold more slowly than the unsealed bread.
In the second sample, the bread kept in darkness should develop mold more quickly than the bread kept in light.
In the third sample, the moist bread will develop mold more quickly than the dry bread.
In the fourth sample, the mold in the warm place should develop mold more quickly than the bread in the cold place.
