Question 1

____ is a large, double-stranded, helical molecule that contains instructions for assembling a living organism from simpler molecules.

Accepted Answer

DNA is the large, double-stranded, helical molecule that contains instructions for assembling a living organism from simpler molecules. RNA is also a nucleic acid that plays a role in protein synthesis, but it is not as large or double-stranded as DNA. ATP and NADPH are molecules that provide energy for cellular processes, while protein is a large biomolecule made up of amino acids and has various functions in the body.

Question 2

A cell is minimally defined by which of the following:

Accepted Answer

A cell is minimally defined by an organized chemical system and specialized molecules surrounded by a membrane, which allows it to maintain homeostasis and perform life functions.

Question 3

All the populations of different organisms that live in the same place form a(n) ____.

Accepted Answer

A community is defined as all the populations of different organisms that live in the same place and interact with each other. An ecosystem includes the community of organisms as well as their physical environment, while the biosphere refers to all the ecosystems on Earth. An organ is a distinct structure made up of tissues that performs a specific function within an organism. And a population refers to a group of individuals of the same species that live in the same area and can interbreed.

Question 4

Living organisms must gather energy and materials from their surroundings to ____.

Accepted Answer

Living organisms require energy and materials from their surroundings to build new biochemicals, grow, maintain and repair their parts, and produce offspring. Therefore, option E, which includes all of these choices, is the correct answer.

Question 5

A(n) ____ includes the community and the nonliving environmental factors with which it interacts.

Accepted Answer

An ecosystem includes both living (community) and nonliving (environmental) factors within a certain area. The biosphere refers to the entire part of Earth in which life exists, which includes multiple ecosystems. A multicellular organism and Earth as a whole do not encompass the full scope of interactions between living and nonliving factors in an ecosystem.

Question 6

Every population of animals has an age structure.The individuals that make up the population are all of a specific age, but individuals do not have an age structure.Age structure is an example of a(n) _____.

Accepted Answer

Age structure is an emergent property, which means it is a characteristic of a system or population that arises from the interactions and relationships between its individual components. In this case, the age structure of a population emerges from the distribution of individuals of different ages within the population.

Question 7

As long as a cell has access to a usable energy source, has the necessary raw materials, and is in appropriate environmental conditions, the cell will:

Accepted Answer

Cells need energy, raw materials, and appropriate environmental conditions to carry out essential cellular processes, including growth and reproduction. Therefore, if a cell has access to a usable energy source, the necessary raw materials, and appropriate environmental conditions, it will be able to survive and reproduce. The other answer choices (B, C, D, and E) do not accurately describe the behavior of cells under these circumstances.

Question 8

The difference between living and nonliving matter depends not only on the kinds of atoms and molecules present, it also depends on ____.

Accepted Answer

The organization and interactions of atoms and molecules determine whether matter is living or nonliving. This includes the way in which these molecules are arranged to form structures such as cells, tissues, and ultimately, organisms. Chemical interactions and complexity are factors that contribute to this organization and interaction, but they are not the sole determinants. Compounds and electrons also play a role in the properties of living and nonliving matter, but again, they are not the primary defining characteristics.

Question 9

The most fundamental and important molecule that distinguishes living systems from nonliving matter is ____.

Accepted Answer

DNA, or deoxyribonucleic acid, is the molecule that contains the instructions for an organism's development and characteristics. It is found in the nucleus of cells and is responsible for transmitting genetic information from one generation to the next.

Question 10

____ contain DNA, but are not considered to be alive because they cannot reproduce independently of their host.

Accepted Answer

Viruses contain DNA or RNA, but they are not considered to be alive because they cannot reproduce independently of their host cell. They require a host cell's machinery to replicate their genetic material and produce new virus particles.

Question 11

It is through ____ that we further our knowledge of living things.

Accepted Answer

Biological research involves the scientific study of living organisms, including their origins, behaviors, and interactions with their environment. This research allows us to expand our understanding and knowledge of living things. The other options listed may also contribute to knowledge and understanding, but they are not the primary means by which we further our knowledge of living things.

Question 12

Emergent properties are

Accepted Answer

Emergent properties are characteristics that arise from the interactions and organization of simpler components at a higher level of organization. These properties are not present at lower levels of organization and cannot be predicted from the properties of the individual components alone. This is true for complex systems such as biological organisms, ecosystems, and even social structures. Emergent properties are not exclusive to any particular type of matter or organism, and can be seen at various levels of organization.

Question 13

The information in DNA is copied into molecules of ____.

Accepted Answer

The information in DNA is transcribed into RNA molecules through a process called transcription. RNA carries genetic information to the ribosomes where it is translated into proteins. Therefore, option E, RNA, is the correct answer. Options A, B, C, and D are not involved in the process of genetic information transfer from DNA to proteins.

Question 14

Destruction of forest ecosystems in Brazil affects the amount of CO₂ taken up from the atmosphere.In consequence, altered levels of atmospheric CO₂ may affect the climate in the American midwest.A person who studies these types of interactions would probably be called a(n) _____.

Accepted Answer

The answer of Destruction of forest ecosystems in Brazil affects...

Question 15

Bacteria and protozoans are ____.

Accepted Answer

Bacteria and protozoans are both unicellular organisms, meaning they are made up of only one cell. They do not have specialized tissues or structures like multicellular organisms do.

Question 16

The science of ____ explains the origin of life, the persistence of life, and studies the changes in living things.

Accepted Answer

Biology is the study of life and its processes, including the origin, persistence, and changes of living organisms. Nanotechnology, mathematics, chemistry, and pharmacology are all important fields of study, but they do not specifically focus on the scientific study of living organisms.

Question 17

The highest level of the hierarchy of life is the ____.

Accepted Answer

The biosphere is the highest level of the hierarchy of life, encompassing all of the Earth's ecosystems and living organisms. It includes interactions between living and nonliving components of the environment and is the largest unit of ecological organization. Populations, ecosystems, multicellular organisms, and cells are all components of the biosphere but are not the highest level of organization.

Question 18

Which of the following is NOT a logical hierarchy of biological organization?

Accepted Answer

The correct hierarchy should be molecules, organelles, cells, tissues, organs, organ systems, organisms. The sequence in option C is incorrect.

Question 19

A group of organisms of the same species that live together in the same place make up a(n) ____.

Accepted Answer

A population refers to a group of individuals of the same species that live in the same place and can potentially interbreed. Options A, B, C, and E refer to different levels of biological organization but do not specifically refer to a group of organisms of the same species.

Question 20

The lowest level of biological organization that can survive and reproduce is the ____.

Accepted Answer

A cell is the lowest level of biological organization that can survive and reproduce. Protons and nuclei are subcellular components and cannot survive on their own. DNA is not capable of life on its own and requires a cell to function. Tissue is a collection of cells and cannot survive on its own.
