Q: What is the correct sequence of the central dogma of molecular biology?

$$\text{DNA} \rightarrow \text{RNA} \rightarrow \text{Protein}$$

Question 1

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

Accepted Answer

Structure dictates function, meaning the way something is arranged enables it to play its role within an organism.

Question 2

Which level of biological organization is correctly matched with its description?

Accepted Answer

Ecosystem: All the living things and non-living things within the environment in a particular area.

Question 3

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

Accepted Answer

Prokaryotic cells are generally smaller and do not contain a nucleus.

Question 4

Which process best explains how genetic information is transmitted from parents to offspring?

Accepted Answer

Chromosomes containing DNA are inherited from both parents, and DNA directs cell development.

Question 5

What is the correct sequence of the central dogma of molecular biology?

Accepted Answer

$$	ext{DNA} ightarrow 	ext{RNA} ightarrow 	ext{Protein}$$

Question 6

Which of the following best describes the flow of energy in an ecosystem?

Accepted Answer

Energy enters as light, is transformed by producers, and exits as heat.

Question 7

A cattle egret riding on a buffalo is an example of which type of ecological interaction?

Accepted Answer

Commensalism

Question 8

Which of the following is NOT a domain of life?

Accepted Answer

Plantae

Question 9

Which statement best summarizes Darwin’s theory of natural selection?

Accepted Answer

Populations evolve as individuals with advantageous traits survive and reproduce more successfully.

Question 10

In a controlled experiment testing the effect of mouse coat color on predation, which is the independent variable?

Accepted Answer

The color of the mouse model

Question 11

Which of the following best describes a scientific theory?

Accepted Answer

A theory is a broad explanation supported by a large body of evidence and can generate new hypotheses.

Question 12

Which of the following is a correct example of reductionism in biology?

Accepted Answer

Breaking down complex biological systems into simpler components to study their function.

Question 13

Which of the following is a property shared by all cells?

Accepted Answer

Presence of a cell membrane

Question 14

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

Accepted Answer

DNA provides the instructions for making proteins, which are essential for cell structure and function.

Question 15

Which of the following is a correct description of an amino acid?

Accepted Answer

A molecule with a central carbon, an amino group ($$\mathrm{NH_2$}$$), a carboxyl group ($$\mathrm{COOH}$$), a hydrogen atom, and a variable side chain (R group).

Question 16

Which of the following is an example of mutualism?

Accepted Answer

Fish eating parasites off turtles, benefiting both species

Question 17

Which of the following best explains why energy cannot be recycled in an ecosystem?

Accepted Answer

Energy is lost as heat during each transformation, so it must be continually supplied by the sun.

Question 18

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

Accepted Answer

Predicting that all plants photosynthesize because you have observed many plants that do.

Question 19

Which of the following best describes the difference between a hypothesis and a theory in science?

Accepted Answer

A hypothesis is a testable explanation for a specific observation, while a theory is a broad explanation supported by extensive evidence.

Question 20

Which of the following is an example of a dependent variable in a biological experiment?

Accepted Answer

The amount of predation observed on different colored mouse models.
