Question 1

Living organisms on Earth share many common characteristics. Which statements are TRUE and which are FALSE about nearly all living things?
-In multicellular organisms,tissues are comprised of many different types of cells.

Accepted Answer

In multicellular organisms, tissues are typically comprised of similar types of cells that work together to perform a specific function.

Question 2

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

Accepted Answer

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

Question 3

Living organisms on Earth share many common characteristics. Which statements are TRUE and which are FALSE about nearly all living things?
-Only multicellular organisms need to maintain homeostasis.

Accepted Answer

Homeostasis is a characteristic of all living organisms, including unicellular ones, as it is essential for maintaining stable internal conditions necessary for survival.

Question 4

The ultimate source of energy for nearly all forms of life on Earth is water.

Accepted Answer

The ultimate source of energy for nearly all forms of life on Earth is the Sun, as it provides the energy needed for photosynthesis, which is the foundation of most food chains.

Question 5

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 is used as a baseline to compare the effects of the variable being tested, so it receives all the same conditions except for the independent variable.

Question 6

Choose the correct order of classification from most inclusive to most exclusive.
A)Domain-Kingdom-Phylum-Class-Order-Family-Genus-Species
B)Kingdom-Domain-Class-Phylum-Order-Family-Genus-Species
C)Kingdom-Domain-Class-Phylum-Order-Genus-Species-Family
D)Kingdom-Class-Phylum-Domain-Genus-Order-Family-Species

Accepted Answer

The correct order of classification from most inclusive to most exclusive is: Domain-Kingdom-Phylum-Class-Order-Family-Genus-Species. This is because the domain is the most inclusive level of classification, and the species is the most exclusive level of classification.

Question 7

Living and nonliving entities share some characteristics. Which statements are TRUE and which are FALSE about the living and nonliving components of an ecosystem?
-All living things and nonliving materials exhibit homeostatic controls.

Accepted Answer

Homeostatic controls are characteristic of living organisms, allowing them to maintain internal stability. Nonliving materials do not exhibit homeostasis.

Question 8

Living organisms are characterized by
A)adapting to the environment.
B)evolving over time.
C)displaying homeostatic controls.
D)All of the choices pertain to living organisms.

Accepted Answer

Living organisms are characterized by their ability to adapt to the environment, evolve over time, and maintain homeostasis, so all the choices pertain to living organisms.

Question 9

Living organisms on Earth share many common characteristics. Which statements are TRUE and which are FALSE about nearly all living things?
-All living organisms are made up of cells.

Accepted Answer

All living organisms are composed of one or more cells, which are considered the basic units of life.

Question 10

Living organisms on Earth share many common characteristics. Which statements are TRUE and which are FALSE about nearly all living things?
-Living things must have an outside source of nutrients and energy.

Accepted Answer

Living organisms require nutrients and energy from external sources to sustain life processes such as growth, reproduction, and maintenance of cellular functions.

Question 11

The selective agents for natural selection can be either abiotic or biotic.

Accepted Answer

Natural selection can be influenced by abiotic factors like climate and biotic factors like predators.

Question 12

Living and nonliving entities share some characteristics. Which statements are TRUE and which are FALSE about the living and nonliving components of an ecosystem?
-All matter,whether alive or not,is comprised of atoms.

Accepted Answer

All matter, whether living or nonliving, is made up of atoms, which are the basic building blocks of matter.

Question 13

Living and nonliving entities share some characteristics. Which statements are TRUE and which are FALSE about the living and nonliving components of an ecosystem?
-All living things and nonliving materials are made of cells.

Accepted Answer

Living things are made of cells, but nonliving materials are not composed of cells. Nonliving materials may be composed of atoms and molecules but do not have the cellular structure characteristic of living organisms.

Question 14

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?
A)a scientific model
B)an experiment
C)descriptive research
D)a scientific theory or principle
E)experimental results

Accepted Answer

A scientific theory or principle is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has stood up to repeated testing and observation.

Question 15

Due to human activities,more carbon dioxide is being released into the atmosphere than is being removed.What happens to this extra carbon dioxide? Select all that apply.
A)Some of the carbon dioxide stays in the atmosphere which causes surface temperature to rise.
B)Approximately half of the extraneous carbon dioxide is being expelled into deep space.
C)Much of the extraneous carbon dioxide is dissolved into the oceans where it is causing acidification.
D)Trees and other plants have increased their rates of photosynthesis and are effectively removing most of the extraneous carbon dioxide.

Accepted Answer

Some of the extra carbon dioxide remains in the atmosphere, contributing to the greenhouse effect and global warming. Additionally, a significant portion is absorbed by the oceans, leading to ocean acidification.

Question 16

Single-celled prokaryotes
A)lack a membrane-bounded nucleus.
B)are classified in the domains Bacteria and Archaea.
C)are found in almost all habitats.
D)All of the choices are correct.

Accepted Answer

Single-celled prokaryotes lack a membrane-bounded nucleus, are classified in the domains Bacteria and Archaea, and are found in almost all habitats, making all the choices correct.

Question 17

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
A)population geneticist.
B)molecular biologist.
C)ecosystem ecologist.
D)organismal physiologist.
E)island zoologist.

Accepted Answer

The position should be titled "ecosystem ecologist" because the job involves studying the interactions among various species (wolves, moose, trees) and their environment (physical features), which is the focus of ecosystem ecology.

Question 18

In the scientific method,what precedes the formation of the hypothesis?
A)a prediction
B)experimentation
C)analysis of results
D)observation

Accepted Answer

Observation precedes the formation of a hypothesis as it involves gathering data and noticing patterns or phenomena that lead to a question or hypothesis.

Question 19

Which listing correctly indicates a sequence of increasing biological organization?
A)molecule,cell,organelle,atom
B)organelle,tissue,cell,molecule
C)organ,tissue,atom,molecule
D)atom,molecule,organelle,cell

Accepted Answer

The correct sequence of increasing biological organization is atom, molecule, organelle, cell. Atoms combine to form molecules, molecules form organelles, and organelles are components of cells.

Question 20

Climate change is primarily due to an imbalance in the chemical cycling of the element carbon.

Accepted Answer

Climate change is largely driven by increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which result from human activities such as burning fossil fuels and deforestation, disrupting the natural carbon cycle.
