Which of the following are true concerning living things? Check all that apply.
A)They contain a vital force absent in nonliving things.
B)They are composed of molecules that contain carbon-carbon bonds.
C)They undergo chemical reactions to use energy they acquire from the environment.
D)They do not require catalysts to sustain their living state.
My answers: A, B, and C
Anyone have answers to the whole test
i believe its B and C
yall do realize the test switches answers right?
if someone gave all of them for theirs then we would get like a 20% cause it switches at random
.........i learned that from experience with a diff subject ack..........
To determine which of the statements are true concerning living things, let's go through each option:
A) They contain a vital force absent in nonliving things.
To verify this statement, we need to understand that modern science does not support the concept of a "vital force" that distinguishes living from nonliving things. The idea of a vital force is a concept from early theories of biology that is not considered accurate today. Therefore, statement A is not true.
B) They are composed of molecules that contain carbon-carbon bonds.
To analyze this statement, we need to consider the basic building blocks of living organisms, which are organic molecules. Carbon-carbon bonds are prevalent in organic molecules, such as carbohydrates, lipids, proteins, and nucleic acids—all essential components of living organisms. Therefore, statement B is true.
C) They undergo chemical reactions to use energy they acquire from the environment.
To evaluate this statement, we can refer to one of the defining characteristics of living things: metabolism. Living organisms engage in chemical reactions, such as respiration or photosynthesis, to acquire and utilize energy from their environment for growth, maintenance, and other life processes. Hence, statement C is true.
D) They do not require catalysts to sustain their living state.
To assess this statement, we must consider that catalysts are substances that increase the rate of chemical reactions without being consumed in the process. Biological systems often rely on enzymes, which are biological catalysts, to facilitate and speed up various biochemical reactions necessary for life. Therefore, statement D is not true.
Based on this analysis, the correct answers are B (They are composed of molecules that contain carbon-carbon bonds) and C (They undergo chemical reactions to use energy they acquire from the environment).
