Marianne is comparing two animals: a fruit fly and a fruit bat. She asks, "Do a fruit fly and a fruit bat share a common ancestor in their evolutionary history?" According to evolutionary theory, what is the answer to Marianne's question? A. Yes, because the fruit fly and fruit bat share the common trait of eating fruit. B. No, because the fruit fly is an insect and the fruit bat is a mammal. C. Maybe, depending on specific traits at the organism and cellular levels of both animals. D. Yes, because all living things share a common ancestor.
Answers
Answer: c. maybe, depending on specific traits at organism in cellular levels of both animals
Explanation:
Evolutionary history has to do with the processes through which living organisms evolve from their ancestors to their present generations.
It's quite possible for the fruit fly and the fruit bat to share a common ancestor based on their evolutionary history depending on specific traits at the organism and cellular levels of both animals.
Therefore, the correct option is C.

Answers
Answer:
According to the evidence, these volcanic eruptions were not the cause of the consistent rise in CO2 levels. If they were, CO2 levels would steadily rise and fall. The chart shows that CO2 levels rose even when there was a drop in volcanic activity. That means some other factors are causing the increase in atmospheric CO2.

Climate change is forcing many animals to adapt to survive. The tawny owl in Finland is a good example. These creatures come in two colors, brown or pale grey. The cold white winters have traditionally favored the pale grey owls, but over the last 50 years as the winters have become milder with less snow precipitation, researchers noticed a shift in the populations. Which statement is correct and why?
Answers
Answer:
Climate change changes the distribution of organisms.
Explanation:
Climate change changes the distribution of organisms because due to climate change, the environment is no longer suitable for many species so the organisms are migrated from that environment to another suitable environment so that's why the pale grey owls population decreases due to change in climatic condition of the environment.

What is a scientific theory?
A structured explanation for a group of facts or phenomena observed in the natural world is called a scientific theory. It often incorporates a scientific hypothesis and/or scientific laws.
The definition or meaning of the word 'scientific theory is different from the definition of the word 'theory' that people use casually.
The use of the word theory by scientists is different from how it is commonly used by the general public. Most common people use the word 'theory' when they mean to describe an idea or a hunch that someone has. For scientists, 'theory' refers to the way of interpreting facts.
A scientific theory does not mean the end of the scientific method. Scientific theories are proven or rejected, just like hypotheses are. Also, these theories are continuously improved or modified if more information regarding them is known. This helps to keep the accuracy of the prediction to become greater over time.
Therefore the correct option is D.

Explanation:
Water has a heat of fusion of 6.01 kJ/mol. An iceberg in the Atlantic Ocean near Newfoundland contains 1.27 x 107 mol of water. How much thermal energy does it absorb as it melts? Answer using appropriate significant digits.
Answers
I believe this is just conversion factors.
*I think the 107 above means 10^7
1.27 * 10^7 mol * 6.01 kJ/ 1 mol = 76,327,000 kJ
That value, rounded to significant figures, produces 763 * 10^5 kJ
*The 1.27 and 6.01 represent the least amount of significant figures; the rule of sig. figs. for division and multiplication is the value with the fewest sig. figs..
(For addition and subtraction, the least amount of decimal places determines the number of sig. figs..)
