Accoring to the data table, Molly observed rust on the sample of iron filing and dries the sample thoroughly. She then finds the mass of the entire sample and finds it has more mass than the 188g of the original sample. As the rusted iron filing occurred in an open system, which of the following best explains the increase in mass?

Select one:
A. The sample gained mass because rust is a different color than the iron fillings, and the different color rust has more mass that the original iron fillings.
B. The sample gained mass because the iron fillings combined with oxygen in a chemical reaction, thus making the final rusted sample to have more mass.
C. Molly made a procedure mistake when measuring the mass of the entire sample. She should remeausre her sample.
D. The sample gained mass because rust is a physical change and the color change causes the mass to be more than the original sample.

Answers

Answer:

a) Jar C, b) Jar A

Explanation:

a) The amount of CO2 is the highest in jar C because it only contains CO2-producing organisms: mice. A plant in the same jar, like in jar B, would counteract this CO2 production by using it to produce oxygen, which would balance it out.

b) Jar A has the lowest amount of CO2 because the plant is by itself only producing oxygen. There is no life form in jar b that produces CO2.

Scientists can learn all of the following by studying fossils EXCEPT:

Question 2 options:

How life forms have changed over time

Answers

Answer: How the surrounding rock layers have changed over time

Explanation:

I’m taking a minion quiz in science class and I submitted it and we’ll that’s the correct answer

The changes in surrounding rock layers over time cannot be studied by fossils. So the correct option is C.

What are the uses of fossils?

We can learn a lot about the Earth's history of life thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.

Important evidence for evolutionary and the environmental adaptability of plants and animals may be found in fossils. Fossil evidence shows how organisms developed and how a "tree of life" may be used to illustrate this process, demonstrating the interconnectedness of all species.

Rocks can also be dated using fossils. Geologists may use fossils to study geological history because different types of fossils appear in rocks of various ages as a result of evolution. Fossils are one of the most crucial instruments for age correlation in geology.

Ammonites, for instance, are great reference fossils for stratigraphy because they may be used to compare the relative ages of two or more strata, or layers of rock, that are located in various locations across the same nation or elsewhere in the world.

Therefore, the correct option is C.

Do you think this indicates that humans are the pinnacle of evolution? Are they? Explain.

Answers

Adaptability to the change environment by the human is the only reason for the survival of human beings as compared to other hominids.
