Answer:
electrolysis
Explanation:
i hope that helps you!
B. The theory might be modified if necessary.
C. Bernoulli will come up with another hypothesis.
D. Bernoulli's principle will be called "Bernoulli's hypothesis."
Bernoulli's principle is a theory given the name "principle" because _____.
A. it is actually more like a hypothesis
B. nearly all scientists agree that it is correct
C. it is one of the first things you would learn about in college
D. you can't provide evidence for it, but scientists know that it is correct
Answer:
B. The theory might be modified if necessary.
B. nearly all scientists agree that it is correct
Explanation:
B. The theory might be modified if necessary.
The Bernoulli's principle relates the speed of fluid to their pressures. It simply states that when the speed of fluids increases there is a drop in pressure.
Supposing we find new evidence about how the principle works, the normal scientific thing to do is to modify the existing principle. New information and observations about a principle would only provide a modification to the existing one. An example is the Dalton's atomic theory, which was centered on the atom being the smallest indivisible particle: the theory was later modified when new ideas about the atom surface.
B. nearly all scientists agree that it is correct
Before a hypothesis is adopted to the context of scientific principle, the ideas behind it must have tested and must be repeatable. Different sources will verify the authenticity of such scientific claim to see if such can be adopted. Therefroe, nearly a large numbr of scientists must agree that it is correct.
The structures of different types of cell organelles are similar.
The functions of most cell organelles are hindered by their structures.
The structure of a cell organelle is directly related to its function.
The function of a cell organelle can change over time.
Answer:
The correct answer will be option- The structure of a cell organelle is directly related to its function.
Explanation:
The cell wall is a layer formed around the plasma membrane of the plant cell which helps plant cell by providing stiffness and support to the cell. This cell wall provides protection to the plant cells.
Since the presence of cell wall around the plasma membrane shows that it has a specific function and serves an important function of the plant cell, similarly the structure of various organelles present in the cell is related to their function. The best-known example is the inner folding of the mitochondria called cristae to increase the surface area.
Thus, the selected option is the correct answer.
5.0 mols Li × 6.94 g Li/ 1 mol Li = 34.7 grams of Li
sig figs: 35 grams of Li
The ways scientists do investigations is observational studies, surveys and questionnaires and case studies,
Scientists use various methods to conduct investigations and explore the natural world. These methods include:
1. Observational Studies: Scientists carefully observe and record natural phenomena or events without intervening or manipulating the environment. Observational studies are often used in fields such as astronomy, ecology, and anthropology.
2. Experimental Studies: Scientists design controlled experiments to test specific hypotheses or investigate cause-and-effect relationships. In experiments, variables are manipulated and controlled to observe their impact on the outcome. This method is common in chemistry, physics, and biology.
3. Surveys and Questionnaires: Researchers use surveys and questionnaires to gather data from a large number of individuals to assess opinions, attitudes, behaviors, or preferences. This method is prevalent in social sciences and market research.
4. Case Studies: In-depth investigations of a particular individual, group, or situation are conducted to gain detailed insights. Case studies are commonly used in psychology, medicine, and sociology.
5. Field Studies: Scientists conduct research directly in the natural environment, collecting data in real-world settings. Field studies are common in geology, environmental science, and wildlife biology.
