Question 4

Which of the following statements about the Laws of Thermodynamics in biological systems is correct?

Accepted Answer

Energy cannot be created or destroyed, only transformed from one form to another.

Question 5

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

Accepted Answer

Eukaryotic cells have a nucleus, while prokaryotic cells do not.

Question 6

Which of the following is a correct statement about the structure of water and its importance to life?

Accepted Answer

Water's polarity allows it to form hydrogen bonds, which contribute to its high specific heat and cohesion.

Question 7

A student is asked to differentiate between organic and inorganic compounds. Which of the following is an example of an organic compound?

Accepted Answer

C_6H_{12}$$O_6 ($$glucose)

Question 8

Which process is responsible for the inheritance of genetic traits from one generation to the next?

Accepted Answer

Replication

Question 9

Accepted Answer

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

Question 10

Which of the following is NOT a shared characteristic of all living things?

Accepted Answer

Ability to photosynthesize

Question 11

Which of the following best explains the difference between mitosis and meiosis?

Accepted Answer

Mitosis is used for growth and repair, producing identical cells; meiosis is used for sexual reproduction, producing genetically diverse gametes.

Question 12

Which of the following is a correct statement about the fluid mosaic model of the plasma membrane?

Accepted Answer

Proteins and lipids move freely within the membrane, creating a dynamic and flexible structure.

Question 13

Which of the following is a correct example of how structure and function are interrelated in biological systems?

Accepted Answer

The shape of an enzyme determines its ability to catalyze specific reactions.

Question 14

Which of the following best describes the role of enzymes in cellular metabolism?

Accepted Answer

Enzymes act as catalysts, lowering the activation energy and speeding up chemical reactions.

Question 15

Which of the following statements about the theory of evolution is supported by scientific evidence?

Accepted Answer

Species change over time through natural selection and adaptation to their environment.

Question 16

A population of beetles is exposed to a pesticide. Over several generations, most beetles become resistant to the pesticide. Which concept does this scenario best illustrate?

Accepted Answer

Natural selection

Question 17

Which of the following is a correct statement about the relationship between energy and matter in living systems?

Accepted Answer

Living systems transform energy and matter to maintain life functions.

Question 18

Which of the following is a correct example of information flow in biological systems?

Accepted Answer

Genetic information is transcribed from DNA to RNA and then translated into proteins.

Question 19

Which of the following best describes the emergent properties of biological systems?

Accepted Answer

Emergent properties are characteristics that arise from the interaction of individual components, resulting in new functions at higher levels of organization.
