Biology: The Study Of Life

2.

To be classified as 'living', you must meet:

At least 2 of the characteristics of living things.
At least 4 of the characteristics of living things.
At least 6 of the characteristics of living things.
All 8 of the characteristics of living things.

Correct Answer

A. All 8 of the characteristics of living things.

Explanation

Living things possess certain characteristics that distinguish them from non-living things. These characteristics include organization, energy utilization, homeostasis, growth and development, reproduction, response to stimuli, adaptation, and evolution. In order to be classified as "living," an entity must exhibit all 8 of these characteristics. Meeting only 2, 4, or 6 of these characteristics would not be sufficient to be considered living.

The 8 Characteristics of Living things are:

Reproduction, Movement, Cardiovascular, Understanding, Growth, Respiration, Sensitivity, Nutrition
Movement, Respiration, Sensitivity, Circulation, Nutrition, Excretion, Reproduction, Growth
Respiration, Photosynthesis, Consumption, Cardiovascular, Thinking, Reproduction, Excretion, Sensitivity
Movement, Rationality, Sensitivity, Circulation, Nerves, Excretion, Reasoning, Growth

Correct Answer

A. Movement, Respiration, Sensitivity, Circulation, Nutrition, Excretion, Reproduction, Growth

Explanation

The answer "Movement, Respiration, Sensitivity, Circulation, Nutrition, Excretion, Reproduction, Growth" accurately lists the 8 characteristics of living things. Movement refers to the ability of living organisms to change their position or location. Respiration is the process of obtaining energy from food and releasing waste products. Sensitivity refers to the ability to respond to stimuli in the environment. Circulation refers to the movement of fluids within an organism. Nutrition involves obtaining and processing nutrients for energy and growth. Excretion is the process of eliminating waste products. Reproduction is the ability to produce offspring. Growth refers to the increase in size or number of cells in an organism.

Chemical energy is:

The potential energy stored in substances & this energy becomes available when certain types of chemical reactions occur.
The principle source of energy for life on Earth.
Produced when molecules in a substance move.
Available in the form of glucose, as soon as photosynthesis takes place in plants.

Correct Answer

A. The potential energy stored in substances & this energy becomes available when certain types of chemical reactions occur.

Explanation

Radiant energy (sunlight) is the principle source of energy for life on Earth.
Heat energy is produced when molecules in a substance move.
Chemical energy is only available to most organisms after respiration takes place.
