Question 1

Groups of different species that live and interact in a given area are referred to as a

Accepted Answer

A community refers to the different species that live and interact in a given area. The biosphere is the global sum of all ecosystems, populations refer to individuals of the same species, and habitats are the physical environments in which organisms live.

Question 2

Mediterranean gardeners' repeated replanting of seeds from wild mustard plants that showed unusually prolific flower bud and flower growth led to the creation of what modern cruciferous plants?

Accepted Answer

The repeated replanting of seeds from wild mustard plants that showed unusually prolific flower bud and flower growth ultimately led to the creation of broccoli and cauliflower, both of which are cruciferous vegetables. While turnips and kohlrabi are also cruciferous vegetables, they were not specifically mentioned in the given context of this question. Kale and cabbage were not the result of the Mediterranean gardeners' replanting of wild mustard seeds, and cauliflower was not paired with kale, as option C suggests.

Question 3

Which of the following statements does NOT describe a characteristic of living organisms?

Accepted Answer

The answer of Which of the following statements does NOT...

Question 4

A group of interbreeding organisms whose offspring are themselves fertile is defined as a

Accepted Answer

The definition given in the question is that of a species, which is the correct answer. A web refers to a complex network of interconnected entities, a biome is a large geographical region defined by its climate and biological characteristics, and a unit is a broad term that can refer to many different things without context.

Question 5

In which of the following foods would the energy content be most directly connected to solar energy?

Accepted Answer

An apple grows on a tree using energy from the sun through the process of photosynthesis, which directly connects its energy content to solar energy.

Question 6

More than one adaptive trait in the pronghorn has been influenced by the presence of predators; in addition to its great speed,the pronghorn also has

Accepted Answer

The camouflage coloration is likely an adaptation to help the pronghorn blend into its environment and avoid detection by predators. The other options listed do not have a clear connection to predator pressure.

Question 7

All living organisms share a unity in their characteristics because they

Accepted Answer

The statement "descended from a common ancestor" explains the unity in characteristics seen across all living organisms. All life on Earth shares a common genetic code and biochemical pathways, indicating a shared ancestry. This concept is supported by evidence from fields such as molecular biology, comparative anatomy, and paleontology.

Question 8

Which of the following groups of organisms is NOT included in the domain Eukarya?

Accepted Answer

Domain Archaea is a distinct domain of life that includes bacteria-like organisms that are evolutionarily distinct from other forms of life, including eukaryotes, and so they are not included in the domain Eukarya. The other three groups mentioned in the options - Protista, Fungi, and Plantae - are all part of the domain Eukarya.

Question 9

Homeostasis is the ability to detect and correct disturbances that develop within an organism.Which of the following things is NOT regulated by homeostasis?

Accepted Answer

External temperature is not regulated by homeostasis; instead, organisms regulate their internal environment to maintain stable conditions despite changes in external temperature.

Question 10

Which of the following sequences correctly represents the biological hierarchy of a multicellular organism?

Accepted Answer

This sequence correctly represents the hierarchy, starting from the basic unit of life (cells) to tissues, organs, organ systems, and finally the whole individual organism.

Question 11

Biologists hypothesize that the now-extinct American cheetah provided the selection pressure that led to the swiftness of the pronghorn.Which of the following statements is the most likely prediction of how pronghorn speed might change in the next few thousand years?

Accepted Answer

In the absence of the American cheetah, there may be less selection pressure for extreme speed, allowing pronghorns to allocate resources to other traits that enhance survival and reproduction.

Question 12

Which of the following statements about how organisms obtain energy is true?

Accepted Answer

Consumers obtain their energy from other organisms, while producers are able to convert energy from the sun into chemical energy through photosynthesis, representing the initial energy transfer in the sequence of energy transfers between the environment and living organisms. Therefore, option A and B are incorrect. Option D is also incorrect, as consumers are not the initial energy transfer, but rather obtain their energy from producers or other consumers.

Question 13

In the following list,the best evidence for evolution is

Accepted Answer

The changes in the overall genetic characteristics of a group of organisms provide the best evidence for evolution, as it shows how populations have adapted and changed over time through natural selection and other mechanisms. The other options, such as predator-prey relationships, adaptive traits, and the existence of certain organisms, may support the idea of evolution, but they do not provide as direct and conclusive evidence as genetic changes.

Question 14

Modern life often masks the struggles that have characterized human life through much of its history.In the past,human survival was critically dependent on our ability to

Accepted Answer

Throughout history, humans have relied on their ability to solve complex problems to adapt to changing environments, secure food, and develop tools and strategies for survival.

Question 15

All animals have the capacity to sense their environment and respond to it.Which of the following statements is an example of this process?

Accepted Answer

Option D acknowledges that humans have specific sensory adaptations that are appropriate for their biology and environment, implying that animals have an innate capability to sense their surroundings and respond accordingly. Options A, B, and C are incorrect because they claim that humans have better sensory abilities than any other animal, which is not valid.

Question 16

Which of the following groups of organisms is NOT included in the domain Eukarya?

Accepted Answer

The answer of Which of the following groups of organisms...

Question 17

Charles Darwin introduced the concept of adaptation,which he defined as features that

Accepted Answer

Darwin defined adaptation as features that help organisms survive and reproduce. Other choices do not accurately reflect his definition of adaptation.

Question 18

Multicellular organisms are constructed from many types of specialized cells.Why might having specialized cells be more advantageous than being a single-celled organism?

Accepted Answer

Specialized cells can perform specific functions more efficiently than single cells that have to do everything themselves. For example, muscle cells are designed for contraction, while nerve cells are designed for transmitting electrical signals. This specialization allows for more effective and efficient functioning of the organism as a whole.

Question 19

Viruses cannot reproduce on their own; they do so by taking over the machinery that exists in the cells of the organisms they invade,whether those organisms are bacteria,plants,or animals.Vaccinations can provide lifelong protection against some diseases,but flu vaccines are rarely effective against the next year's flu virus.Which of the following statements is most likely to explain this fact?

Accepted Answer

Flu viruses can evolve and mutate quickly, which can lead to changes in their surface proteins that are targeted by vaccines. This makes it difficult to create a vaccine that can effectively protect against all strains of the flu virus.

Question 20

An organ is defined as a body structure composed of two or more

Accepted Answer

An organ is composed of two or more tissues which work together to perform a specific function. Therefore, choice C (tissues) is the best answer as it represents the structure of an organ. Choices A (molecules) and B (cells) are incorrect as they do not represent the complexity of an organ structure. Choice D (organ systems) is incorrect as it represents a higher level of organization than an organ.
