Question 1

Which of the following best describes an emergent property in biological systems?

Accepted Answer

A property that arises only when simpler components interact and are organized into higher levels of complexity.

Question 2

Which of the following statements about prokaryotic and eukaryotic cells is correct?

Accepted Answer

Prokaryotic cells lack a nucleus and membrane-enclosed organelles, while eukaryotic cells contain both.

Question 3

A hummingbird’s ability to hover and feed on nectar is an example of which unifying theme in biology?

Accepted Answer

The correlation between structure and function.

Question 4

Which process is illustrated by the sequence: DNA → mRNA → Protein?

Accepted Answer

Gene expression

Question 5

Which of the following best explains why photosynthesis cannot occur if chlorophyll and other chloroplast molecules are simply mixed in a test tube?

Accepted Answer

Photosynthesis requires the emergent properties that arise from the specific organization of molecules within the chloroplast.

Question 6

Which of the following is NOT a property associated with living things, as shown in the first image?

Accepted Answer

Spontaneous generation

Question 7

The Cell Theory states that:

Accepted Answer

All living organisms are made of cells, which are the basic unit of life.

Question 8

Which of the following best describes the role of DNA in cells?

Accepted Answer

DNA encodes the information necessary to build all molecules synthesized within a cell.

Question 9

Which of the following is a correct statement about the universality of the genetic code?

Accepted Answer

A particular sequence of nucleotides means the same thing in one organism as it does in another.

Question 10

Which of the following equations best represents the flow of genetic information in a cell?

Accepted Answer

$$DNA \rightarrow RNA \rightarrow Protein$$

Question 11

Which of the following is an example of the transfer and transformation of energy and matter in living systems?

Accepted Answer

A plant using sunlight to convert carbon dioxide and water into glucose and oxygen.

Question 12

Which of the following best describes the difference between genomics and proteomics?

Accepted Answer

Genomics is the study of sets of genes and their properties, while proteomics is the study of sets of proteins and their properties.

Question 13

Which of the following is a function of bioinformatics in modern biology?

Accepted Answer

Storing, organizing, and analyzing large volumes of biological data.

Question 14

Which of the following is a correct statement about the relationship between structure and function in biology?

Accepted Answer

The structure of a biological component often gives clues about its function.

Question 15

Which of the following best describes reductionism in biology?

Accepted Answer

Breaking down complex systems into simpler components for study.

Question 16

Which of the following is a direct result of gene expression?

Accepted Answer

The synthesis of a functional protein from the information encoded in a gene.

Question 17

Which of the following is an example of evolutionary adaptation?

Accepted Answer

A population of insects developing resistance to a pesticide over several generations.

Question 18

Which of the following best describes the role of RNA in gene expression?

Accepted Answer

RNA acts as an intermediary, carrying genetic information from DNA to the protein-synthesizing machinery.

Question 19

Which of the following is a correct statement about the inheritance of genetic information?

Accepted Answer

Genetic information is transmitted from parents to offspring through DNA.

Question 20

Which of the following is an example of a system studied in systems biology?

Accepted Answer

A leaf cell, a frog, an ant colony, or a desert ecosystem.
