Question 1

Both living and nonliving entities are organized at the cellular level

Accepted Answer

Only living entities are organized at the cellular level, as cells are the basic unit of life. Nonliving entities do not have cells.

Question 2

Both living and nonliving entities exhibit homeostatic controls

Accepted Answer

Homeostasis refers to the self-regulating processes by which biological organisms maintain stability while adjusting to conditions that are optimal for survival. Nonliving entities do not exhibit homeostatic controls as they do not have the biological systems necessary to regulate internal conditions.

Question 3

The control group in an experiment receives all the same treatments as the experimental group(s),except for the one variable being tested.

Accepted Answer

The control group serves as a comparison to the experimental group and is used to determine whether changes in the experimental group are due to the variable being tested or to other factors. By receiving all the same treatments except for the one variable being tested, any differences between the control group and the experimental group(s) can be attributed to the variable being tested.

Question 4

The classification system most commonly used by biologists today contains five domains.

Accepted Answer

The classification system used by biologists today contains three domains: Bacteria, Archaea, and Eukarya.

Question 5

Which of the following terms best describes a conceptual scheme in science that is strongly supported,has not yet been found incorrect,and is based on the results of many observations?

Accepted Answer

A scientific theory or principle is a conceptual scheme in science that is strongly supported, has not yet been found incorrect, and is based on the results of many observations. This is different from a scientific model, which is a simplified representation of a complex phenomenon used for explanation or prediction, and experimental results, which are the specific outcomes observed in a scientific experiment. Descriptive research is a type of research method that aims to observe and describe phenomena as they occur, but it does not necessarily involve the development of a conceptual framework or theory.

Question 6

Extinction can occur if a species is unable to adapt to a changing environment.

Accepted Answer

This statement is true. Extinction can occur if a species is unable to adapt to a changing environment, leading to their inability to survive and reproduce. This is often caused by human activities such as habitat destruction, pollution, and climate change, as well as natural changes in the environment such as natural disasters and competition with other species.

Question 7

Both living and nonliving entities adapt to the environment

Accepted Answer

The answer of Both living and nonliving entities adapt to...

Question 8

A university biology department wishes to hire a scientist to work on the relationships among the wolves,moose,trees and physical features on an island.If you were charged with writing the job description,you should title the position

Accepted Answer

A community ecologist studies the interactions among the living and non-living components of an ecosystem. In this case, the job description is focused on the relationships between the wolves, moose, trees, and physical features on an island, which are all components of the ecosystem. Therefore, a community ecologist would be the best fit for this position. The other options, such as a molecular biologist or organismal physiologist, are more focused on studying the genetics or physiology of individual organisms, rather than the wider ecosystem. The term "island zoologist" is not a common job title and does not accurately capture the scope of the job description.

Question 9

Living things must obey the laws of chemistry and physics

Accepted Answer

All living things are made up of atoms and molecules and their biological processes are governed by the same chemical and physical laws as non-living matter. Therefore, living things must obey the laws of chemistry and physics.

Question 10

Living things show biological organization and other common characteristics of life

Accepted Answer

Living things exhibit a hierarchical organization, meaning that they are composed of cells, which are organized into tissues, then into organs, and finally into organ systems. They also demonstrate other common characteristics of life, such as metabolism, growth, reproduction, response to stimuli, homeostasis, and adaptation.

Question 11

Humans have an exaggerated impact on the ecosystem through their use of extra sources of energy and raw materials,and the production of extra wastes that must be handled.

Accepted Answer

The statement is true, as humans have disrupted the natural balance of the ecosystem by relying heavily on non-renewable resources, generating large amounts of waste, and contributing to climate change.

Question 12

Living things are composed only of organic elements,whereas nonliving things are made up of inorganic elements

Accepted Answer

Both living and nonliving things are composed of both organic and inorganic elements. Living organisms contain organic compounds like carbon, hydrogen, and oxygen, but also require inorganic elements like minerals. Nonliving things can also contain organic compounds, such as fossil fuels.

Question 13

Choose the correct order of classification from most inclusive to exclusive.

Accepted Answer

This is the correct order of classification from most inclusive to exclusive. Domain includes multiple kingdoms, kingdom includes multiple phyla, phylum includes multiple classes, and so on. Species is the most exclusive category and is specific to only one type of organism.

Question 14

Unicellular prokaryotes

Accepted Answer

All of the choices are correct. Unicellular prokaryotes, such as bacteria and archaea, lack a membrane-bounded nucleus and are found in almost all habitats. They are classified in the domains Bacteria and Archaea.

Question 15

Both living and nonliving entities are composed of chemical elements

Accepted Answer

All living and nonliving entities are composed of chemical elements.

Question 16

Living organisms are characterized by:

Accepted Answer

All of the choices pertain to living organisms. Adapting to the environment and evolving over time are key features of living organisms, but so is the ability to maintain homeostasis, or stable internal conditions. Therefore, all of the choices listed are important characteristics of living organisms.

Question 17

Living things are made up of cells

Accepted Answer

This is one of the fundamental characteristics of life. All living organisms, whether unicellular or multicellular, are composed of one or more cells.

Question 18

Emergent properties can be used to distinguish living things from nonliving things

Accepted Answer

Emergent properties are characteristics or features that arise from the interactions and organization of simpler components within a system. One of the defining emergent properties of living things is their ability to carry out complex processes such as metabolism, growth, and reproduction, which result from the coordinated actions of cells and tissues within an organism. Nonliving things lack this type of organization and complexity, and therefore do not exhibit the same emergent properties as living things.

Question 19

A hypothesis is tested by:

Accepted Answer

A hypothesis is tested by experimenting, which allows scientists to collect data that can be analyzed to either support or reject the hypothesis. A prediction is a statement about what might happen based on the hypothesis, but it is not a test of the hypothesis itself. Formulation of a theory comes after multiple hypotheses have been tested and supported by evidence.

Which listing correctly indicates a sequence of increasing biological organization?

Accepted Answer

The answer of Which listing correctly indicates a sequence of...
