Which of the following methods used to enumerate cells often requires specialized staining to observe non-pigmented bacteria?

Osmosis is the specific movement of solvent molecules through a semi-permeable membrane, while diffusion is the general movement of particles from high to low concentration in any medium.

Osmosis and diffusion are both fundamental processes of passive transport. Osmosis is a subset of diffusion that specifically involves the movement of solvent molecules, usually water, through a semi-permeable membrane to equalize solute concentrations on both sides of the membrane. It's essential in processes like maintaining cell turgidity.

On the other hand, diffusion encompasses the broader concept of particles, including solutes and gases, spreading out from areas of high concentration to low concentration. It occurs in various environments, not limited to membranes, and is vital for processes like gas exchange in respiration and the distribution of nutrients in cells.

Answer:

Producers obtain energy from sunlight, consumers obtain energy from producers, and decomposers obtain their energy from dead living beings.

Explanation:

Producers produce their food by themselves as they are autotrophic. They obtain mostly their food and energy from the light energy comes from the sun, by the process of photosynthesis.

Consumers are depending on producers for their energy and food. They get energy from producers they eat as food and convert energy from it.

Decomposers get their food or energy by decaying dead living beings or other organic matter. They change these organic matter to energy.

Answer:

1. C

2. D

Explanation:

In an experiment, which aims at solving a particular problem or answering a scientific question about nature, the scientific method is employed. The scientific method contains the following steps:

- Making an observation.

- Asking a question.

- Formulating a hypothesis

- Testing the hypothesis via experimentation

- Analyzing the results

- Conclusion

According to question 1, the PURPOSE of an experiment portrays what is about to be done in a question format. For example, a purpose can go this: What will be the effect of pesticides on the growth of cowpea?. Furthermore, the PURPOSE helps make a research and state a hypothesis in the next step.

- In the analysis of result, the qualitative or quantitative approach is used. The QUANTITATIVE method involves the use of numbers or numerical data to express the outcome or result of the experiment. By counting or measuring, a numerical data is collected and given a unit depending on what is being measured
