Answer:
selective and differential medium
Explanation:
Based on chemical composition, there are different type of media for the cultivation of bacteria:
- Basal media: culture media that needs no enrichment before being used for bacteria cultivation.
- Enriched media: culture media that are enriched with the addition of blood, serum or egg before being used for culturing.
- Selective media: These are media that selectively favour the growth of a bacterium or group of bacteria over others.
- Differential media: Also known as indicator media. They contain a special substance that changes colour to indicate the presence of a bacterium or group of bacteria.
- Transport media: Media that are used in transporting bacteria from point of collection to where they will be cultured.
- Storage media: These are media that are used to store organisms for future use.
<em>Mannitol salt agar selectively favours the growth of the genus Staphylococcus and inhibits the growth of other organisms. It also contains mannitol which gets fermented and change colour to indicate a particular species of the genus. </em><em>Hence, mannitol salt agar could be classified as a selective and differential medium</em>

Answer:
Waves
Explanation:
Waves are moving bodies of water that crash against the shore and cause erosion.
You test a hypothesis by carrying out an experiment.
Answer:
B. Sphagnum moss takes in energy from sunlight.
D. Euglenas carry out photosynthesis.
Explanation:
According to the question, "a self-feeder" means an autotrophic organism i.e. an organism that produces or obtains food by itself. The process by which an autotrophic organism obtains food is referred to as PHOTOSYNTHESIS. Photosynthesis entails the synthesis of food in form of organic compounds in the presence of sunlight.
Based on this, Euglenas, which is a plant-like protist, carrying out photosynthesis and Sphagnum moss, which is a lower plant (bryophyte) taking in energy from sunlight in order to perform photosynthesis are two examples that describes a "self-feeder"
