Question 1

Which of the following is NOT considered a major characteristic of living organisms according to the study materials?

Accepted Answer

Ability to photosynthesize

Question 2

Carl Sagan famously said that the elements making up life are 'star stuff.' Which process is primarily responsible for the formation of elements heavier than hydrogen and helium?

Accepted Answer

Supernova explosions

Question 3

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

Accepted Answer

Structure determines function, and function can provide insight into structure.

Question 4

A scientist observes that the lungs contain millions of tiny sacs called alveoli. What is the primary advantage of this structure for gas exchange?

Accepted Answer

It increases the surface area for gas exchange.

Question 5

Which equation best represents the concept of metabolism as described in the study materials?

Accepted Answer

$$Metabolism = 	ext{Anabolism} + 	ext{Catabolism}$$

Question 6

Which of the following statements about homeostasis is TRUE?

Accepted Answer

Homeostasis is the maintenance of constant internal conditions necessary for life.

Question 7

Which of the following is a correct description of DNA's role in living organisms?

Accepted Answer

DNA encodes genetic information using the sequence of four nucleotides: Adenine, Thymine, Cytosine, and Guanine.

Question 8

Which of the following best explains why scientific theories, such as evolution, are considered stronger than hypotheses?

Accepted Answer

Theories are supported by a vast amount of evidence and are accepted as facts in scientific terms.

Question 9

Which of the following is a defining feature of eukaryotic cells compared to prokaryotic cells?

Accepted Answer

Eukaryotic cells are capable of multicellular life and have a nucleus containing DNA.

Question 10

Which of the following best describes the process of evolution as a scientific theory?

Accepted Answer

Evolution is a scientific theory supported by a vast amount of evidence and explains changes in populations over time.

Question 11

A population of bacteria is exposed to an antibiotic. Some bacteria survive due to a genetic mutation. Which concept does this scenario best illustrate?

Accepted Answer

Natural selection

Question 12

Which of the following is the correct order of biological organization from smallest to largest?

Accepted Answer

Question 13

Which of the following is NOT a domain in the current classification of life?

Accepted Answer

Protista

Question 14

Which of the following statements about scientific laws and theories is correct?

Accepted Answer

Scientific theories explain why phenomena occur, while scientific laws describe how phenomena occur.

Question 15

Which of the following best describes the flow of genetic information in living organisms?

Accepted Answer

Question 16

Which of the following is an example of a multicellular organism?

Accepted Answer

Human

Question 17

Which of the following is a plausible consequence if an organism fails to maintain homeostasis?

Accepted Answer

It may not survive due to inability to maintain necessary internal conditions.

Question 18

Which of the following best explains why all living organisms share similarities in their genetic code?

Accepted Answer

All organisms use the same four nucleotide bases in their DNA.

Question 19

Which of the following is a correct statement about taxonomy?

Accepted Answer

Taxonomy is the science of classifying organisms based on evolutionary relationships.

Question 20

A student claims that scientific theories are just guesses. Which response best corrects this misconception?

Accepted Answer

Scientific theories are supported by extensive evidence and are accepted as facts in scientific terms.
