Question 2

A scientist is studying a newly discovered organism and observes that it has membrane-bound organelles and a nucleus. To which domain does this organism most likely belong?

Accepted Answer

Domain Eukarya

Question 3

Which of the following statements about the flow of energy and cycling of matter in an ecosystem is correct?

Accepted Answer

Energy enters as sunlight and is eventually lost as heat, while matter cycles within the ecosystem

Question 4

A researcher is using high-throughput technology and bioinformatics to analyze the entire set of proteins expressed in a human liver cell. What is the term for this complete set of proteins?

Accepted Answer

Proteome

Question 5

Which of the following best describes the process of gene expression?

Accepted Answer

The conversion of information from a gene to its functional product, often involving RNA as an intermediary

Question 6

In a controlled experiment investigating the effect of camouflage on predation rates in mice, which of the following is the dependent variable?

Accepted Answer

The amount of predation experienced by the mouse models

Question 7

Which of the following is an example of deductive reasoning in scientific inquiry?

Accepted Answer

Predicting that if all organisms are made of cells, then a newly discovered organism will also be made of cells

Question 8

Which of the following is NOT a characteristic of a scientific theory?

Accepted Answer

It can never be tested or falsified

Question 9

A biologist observes that a certain plant species grows taller in sunlight than in shade. She hypothesizes that sunlight increases the rate of photosynthesis, leading to greater growth. Which of the following would be the best experimental design to test this hypothesis?

Accepted Answer

Grow identical plants in both sunlight and shade, measuring their growth rates and controlling for other variables such as water and soil type

Question 10

Which of the following best explains why DNA is considered the universal genetic language of life?

Accepted Answer

All organisms use the same four nucleotide bases in their DNA

Question 11

A population of insects is exposed to a new pesticide. After several generations, most of the population is resistant to the pesticide. Which of the following best explains this observation according to Darwin's theory of natural selection?

Accepted Answer

Insects with natural resistance survived and reproduced, passing the trait to their offspring

Question 12

Which of the following is an example of an emergent property at the ecosystem level?

Accepted Answer

The cycling of nutrients and flow of energy among organisms and their environment

Question 13

Which of the following best describes the relationship between structure and function in biology?

Accepted Answer

The structure of a biological component often provides insight into its function

Question 14

A student claims that because a hypothesis cannot be proven true, it is not useful in science. Which of the following best refutes this claim?

Accepted Answer

A hypothesis can be tested and supported by evidence, increasing confidence in its validity

Question 15

Which of the following is a correct statement about the domains of life?

Accepted Answer

Eukarya includes plants, animals, fungi, and protists

Question 16

Which of the following scenarios best demonstrates the use of a control group in a scientific experiment?

Accepted Answer

Testing a new drug by giving it to one group of patients and giving a placebo to another group

Question 17

Which of the following is an example of inductive reasoning in biology?

Accepted Answer

Concluding that all cells have membranes after observing many different cell types under a microscope

Question 18

A scientist is studying the effect of increased atmospheric $$\mathrm{CO_2$} on $$plant growth. She finds that plants grow faster with higher $$\mathrm{CO_2$}$$, but also notes changes in soil composition. Which theme of biology does this best illustrate?

Accepted Answer

Organisms interact with other organisms and the physical environment

Question 19

Which of the following best describes the difference between prokaryotic and eukaryotic cells?

Accepted Answer

Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells do not

Question 20

Which of the following is a real-world example of the unity and diversity of life explained by evolution?

Accepted Answer

All mammals have similar limb bone structures, but these limbs are adapted for different functions such as flying, swimming, or running
