A. They eat dead or living organisms
Dont live in the same climate or region. Just a guess. Hope this helps.
Answer:
Gram staining procedure is used to differentiate between the gram-positive and gram-negative bacteria. various reagents used in the gram staining are crystal-violet, iodine, ethanol, and safranin.
1. First, the primary strain that is crystal violet is used to stain the bacterial cells present present on the slide.
2. Then the iodine solution is added over the bacterial culture and held for 1 minute. Iodine makes a complex with the crystal violet in the cell wall of bacteria.
3. Then acetone is used as a decolorizer that decolorizes the gram-negative bacteria by dissolving its lipopolysaccharide cell wall but do not decolorize gram-positive bacteria because its cell wall is made up of peptidoglycan layer.
4. The last reagent is safranin which is used to stain decolorized gram-negative cells pink. Therefore the correct order of staining is:
Crystal violet→Iodine→acetone→sefranine
The correct matching of the given terms are as follows;
Adhesion - the ability of two substances to stick together.
Thermal energy - is the random motion of molecules.
Surface tension - is a measure of how difficult it is to break the surface of a liquid.
Evaporation - is the cooling of a surface due to a substance changing from a liquid to a gas.
Temperature - is the average speed of molecules moving within matter.
<h3>What is are the definition of the given terms?</h3>
The definition of the given terms are as follows;
Adhesion is defined as the attractive force which exists between two different molecules which cause them to stick together.
Thermal energy is the random motion of molecules.
Surface tension is a measure of how difficult it is to break the surface of a liquid.
Evaporation is the cooling of a surface due to a substance changing from a liquid to a gas.
Temperature is the average speed of molecules moving within matter.
In conclusion, adhesion involves the attraction between molecules of different substances.
