(15 points)What did the Miller-Urey experiment simulate?
a
primitive Earth conditions
b
modern Earth conditions
c
how the first living organisms began
d
how complex organisms formed
Answers
Answer:
A.
Explanation:
I think and I hope I am so sorry if it is wrong
Answer:
What the Miller-Urey experiment simulated was how the first living organisms began (option c).
Explanation:
The Miller-Urey experiment owes its name to the scientists who developed it, Stanley Miller and Harold Clayton Urey, who in 1953 designed an experiment to demonstrate that organic substances could be produced from inorganic substances under certain environmental conditions that would favor the process.
From the Miller-Urey experiment it was possible to demonstrate, in some way, that the organic substances to constitute the first living organisms were formed from inorganic substances in the primitive atmosphere.
The experiment required subjecting a mixture of ammonia, methane, hydrogen, CO₂, nitrogen and water to elevated temperatures and electrical discharges. The result was the obtaining of some amino acids, acetic acid and glucose.
On this basis, it can be stated that the Miller-Urey experiment simulated how the first living organisms began.
The other options are not correct because:
a and b. The Miller-Urey experiment was not useful for simulating primitive or modern earth conditions.
d. The experiment does not simulate how complex organisms form.
On the graph below, which axis is the dependent variable?A.Flow rate B.Temperature C.All of the above D.There is not enough information to answer this question.
Answers
Answer:
In the graph, the axis of the dependent variable is the ordinate, corresponding to Flow rate (option A).
Explanation:
The graph shows the relationship between the flow rate and temperature, a relationship that is directly proportional: the higher the temperature, the greater the flow rate.
The dependent variable, in the case shown, is the flow rate. This variable is influenced by the independent variable, temperature, which has not been influenced by other variables.

What are the 4 key principals of natural selection and how do they help a population undergo evolutionary change?
Answers
Answer:
Variation, Overproduction, Adaptation, Descent with Modification
Explanation:
Variation: Heritable differences that exist in every population are the basis for natural selection.
Overproduction: Competition between offsprings for resources.
Adaptation: a trait that helps an organism survive and reproduce
Descent with Modification: Natural Selection will result in species with adaptation that are well suited for survival and reproduction.

the process where maiten magma rises and sinks due to tempature of difference, CRIVNCONEO
Answers
Answer:
Convection
Explanation:
The process where molten magma rises and sinks due to the temperature difference is known as CONVECTION.
This occurs when the hot magma moves upward and is cooled and moves downward again to be heated due to temperature difference, and similarly when cold magma moves upward and is heated and moves downward again to be cooled due to temperature difference.
Hence, in this case, the correct answer is CONVECTION

If an atom contains one electron and one proton, will it carry any charge or not?
Answers
Answer:
An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge. Thus, it will be a neutral atom.
Answer:
That atom will not contain any charge because one negative charge of single electron and one positive charge of single proton are neutralized by each other.
