Answer:
Hey mate....
Explanation:
This is ur answer.....
<em>In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.</em>

Answer:
Brain and spinal cord
Explanation:
Meningitis is the inflammation of the protective covering of the meninges, the three membranes covering the brain and spinal cord. Meningitis usually occurs from a viral infection, but may sometimes result from a bacterial or fungal infection, cancer or drug allergies.
Viral and bacterial meningitis may be contagious and can be transmitted through coughing and sneezing.
Symptoms of meningitis include:
- sensitivity to bright light
Treatment is by vaccination, use of antibiotics and antifungal agents.
Answer:
Raising the temperature from 20c to body temperature
Explanation:
The increase in temperature will give the particles more thermo energy therefore it will increase the rate of an enzyme-controlled reaction
Answer:
1. Define a Question to Investigate
As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research. Once scientists have a good question to investigate, they begin to think of ways to answer it.
2. Make Predictions
Based on their research and observations, scientists will often come up with a hypothesis. A hypothesis is a possible answer to a question. It is based on: their own observations, existing theories, and information they gather from other sources. Scientists use their hypothesis to make a prediction, a testable statement that describes what they think the outcome of an investigation will be.
3. Gather Data
Evidence is needed to test the prediction. There are several strategies for collecting evidence, or data. Scientists can gather their data by observing the natural world, performing an experiment in a laboratory, or by running a model. Scientists decide what strategy to use, often combining strategies. Then they plan a procedure and gather their data. They make sure the procedure can be repeated, so that other scientists can evaluate their findings.
4. Analyze the Data
Scientists organize their data in tables, graphs, or diagrams. If possible, they include relevant data from other sources. They look for patterns that show connections between important variables in the hypothesis they are testing.
5. Draw Conclusions
Based on whether or not their prediction came true, scientists can then decide whether the evidence clearly supports or does not support the hypothesis. If the results are not clear, they must rethink their procedure. If the results are clear, scientists write up their fi ndings and results to share with others. The conclusions they draw usually lead to new questions to pursue.
It would disrupt the CO2 cycle, since plants would no longer absorb carbon dioxixde, nor let out oxygen meaning it would also provide animals with little oxygen, and they can’t produce CO2 then either
