I would like some help if that is OK, like soon!:)
1.) A group of scientists proposes an idea that a chemical compound will enable bean plants to grow faster. They grow one group of bean plants in the presence of the compound and another group in the absence of the compound. Then they write up a presentation about the experiment stating that the compound promotes plant growth. Which step is missing in their methodology?
A. A hypothesis.
B. A control group
C. Data Analysis
D. A conclusion
Which of the following best describes the relationship between science and society?
A. Science influences society but society does not influence science.
B. Society influences science but science does not influence society.
C. Science influences society and society influences science.
D. Science and society interact but neither influences the other.
Which of the following is a characteristic that could be applied to both living and nonliving things?
A. Composed of cells that maintain homeostasis.
B. Carry out metabolic reactions.
C. Transfer genetic information to offspring.
D. Contain mostly carbon, hydrogen, oxygen, and nitrogen.
What are your answers?
Oh, I forgot to add that. :D My answers are D,C, and B.
1. A group of scientists proposes an idea that a chemical compound will enable bean plants to grow faster.
They grow one group of bean plants in the presence of the compound and another group in the absence
of the compound. Then they write up a presentation about the experiment stating that the compound
promotes plant growth. Which step is missing in their methodology?
PLEASE
For the first question, the missing step in the methodology is B. A control group. A control group is essential in experiments to have a baseline for comparison, and it helps ensure that any observed effects are due to the compound being tested and not some other factor.
To determine the relationship between science and society, we can eliminate options A and B, as they state that one side does not influence the other. Science and society do indeed interact and influence each other, so the correct answer is C. Science influences society and society influences science. Scientific advancements can have practical applications and impact society, while societal needs and pressures can shape the direction of scientific research.
Regarding the characteristic shared by living and nonliving things, options A and C involve specific biological processes that only apply to living organisms. Option D refers to the chemical composition, which is not a characteristic shared by all living and nonliving things. Therefore, the correct answer is B. Carry out metabolic reactions. Metabolism is a general process that can occur in both living and nonliving systems, involving the transformation of energy and molecules.
