The disk diffusion test is used to compare the effectiveness of antibiotics. The incubated plate (results) will show bacteria growth except where antibiotic has effects. The more effective the drug, the inhibition zone will be greater. So the most effective antibiotic is the one that has the largest inhibition zone around the test site.
Answer:
plant cells have chloroplasts and a cell wall. (they also have one large central vacuole.)
Explanation: Chloroplasts are found only in plant cells. Chloroplasts convert energy from the sun into sugar (glucose). The chloroplast is also where photosythesis happens in the plant cell. The cell wall is also only found in a plant cell. The cell wall protects and mantains the shape of the cell. And you don't have to put this one but the central vacuole is just one big vacuole in a plant cell that stores mainly water and nutrients since plant cells require more water to function, whereas in animal cells they have multiple small vacuoles.
Answer: 1. True
2. Between six and right hours
Explanation:
1. Energy simply refers to the ability to do work. It's the strength that's required to be able to sustain a mental or physical activity.
It should be noted that fir positive interaction, energy requires physical activity, a balanced diet, adequate sleep, satisfying work and opportunities. Therefore, the statement is true.
2. Even though the hours of sleep that's used by people typically varies, adults generally need about six to eight hours of sleep.
