Question

your text lists several criteria that define living organisms; these are listed on the right. match each to its example.

fish are composed of tiny subunits that have all the characteristics of life.

algae use sunlight and chemicals from their environment to make glucose.

as house plants grow, they bend towards the nearest source of light.

all living organisms presently on earth have descended from single - celled organisms originating 3.5 billion years ago.

analysis of a rock indicates that it is primarily composed of iron; analysis of an amoeba indicates that it is primarily composed of carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorous.

choose
living things respond to their external environment.
living things are composed of cells.
living things require energy and raw materials.
living things have a different molecular composition than nonliving things.
living things maintain homeostasis.
livings things grow and reproduce.
populations of living things evolve.

Explanation:

Each example is matched to the defining characteristic of living organisms that it directly illustrates, based on core biological principles.

1. The example about fish being made of tiny life-containing subunits refers to the cellular basis of life.
2. Algae making glucose from sunlight/chemicals describes acquiring energy and raw materials.
3. House plants bending toward light is a response to external environmental stimuli.
4. All life descending from ancient single-celled organisms reflects evolutionary change in populations.
5. The difference in molecular makeup between a rock and an amoeba highlights unique molecular composition of living things.

Answer:

• Fish are composed of tiny subunits that have all the characteristics of life. → Living things are composed of cells.
• Algae use sunlight and chemicals from their environment to make glucose. → Living things require energy and raw materials.
• As house plants grow, they bend towards the nearest source of light. → Living things respond to their external environment.
• All living organisms presently on Earth have descended from single-celled organisms originating 3.5 billion years ago. → Populations of living things evolve.
• Analysis of a rock indicates that it is primarily composed of iron; analysis of an amoeba indicates that it is primarily composed of carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorous. → Living things have a different molecular composition than nonliving things.
