Question 1

Which of these characteristics of living organisms are present in viruses?

Accepted Answer

Viruses can evolve as groups through mutations and genetic reassortment. They do not have cells, do not maintain a constant internal environment, and do not obtain energy from their environment.

Question 2

Which term best describes the temperate deciduous forests that cover the northeastern United States,including the Adirondack Mountains?

Accepted Answer

A biome is a large scale community of flora and fauna occupying a major habitat, such as the temperate deciduous forests in the northeastern United States. The other options are too broad or too specific to describe these forests accurately.

Question 3

During an experimental study,a control group is maintained under a standard set of conditions with no change in the independent variable.The ________ group is maintained under the same standard set of conditions as the control group,but the independent variable is adjusted.

Accepted Answer

The answer of During an experimental study,a control group is...

Question 5

What characteristic is NOT shared by all living organisms?

Accepted Answer

Not all living organisms make their own energy. For example, some organisms rely on consuming other organisms or organic matter for energy, such as parasites or decomposers.

Question 9

The roots of a sunflower plant growing downward while the shoot grows upward and the flower turns toward the sun are examples of what characteristic of all living organisms?

Accepted Answer

The roots of a sunflower plant growing downward, while the shoot grows upward and the flower turns toward the sun, demonstrates that the plant is sensing and responding to its environment. This is a characteristic of all living organisms. The other options, such as reproducing using DNA and making their own energy, are also characteristics of living organisms, but they are not demonstrated by the given example.

Question 10

A way to visualize the breadth and scope of life,from the smallest structures of atoms and cells to the broadest interactions between living and nonliving systems that we can comprehend,is typically referred to as the biological ________.

Accepted Answer

The answer of A way to visualize the breadth and...

Question 11

Living organisms maintain a constant internal environment by sensing and responding to their internal conditions.This stable maintenance of internal conditions is known as

Accepted Answer

The stable maintenance of internal conditions is known as homeostasis. Organisms constantly sense their internal environment and respond accordingly to maintain a stable and optimal internal environment. Evolution, reproduction, and sensation are also important biological processes, but they do not specifically refer to the maintenance of internal conditions.

Question 12

A species of butterflies gradually becomes darker in color over many generations; this is an example of which characteristic of living organisms?

Accepted Answer

This is an example of evolution, which is the process by which species change over time. Evolution can happen at the level of the individual, but it is most significant at the level of populations and species. Therefore, this is an example of organisms evolving as a group. Option A refers to a characteristic of reproduction, Option B describes metabolism, and Option D describes the process of sensing and responding to the environment, but neither of these relate to the change in coloration over time.

Question 13

After observing that students who regularly attend class appear to be making good grades,I propose the hypothesis that regular class attendance increases the probability that students earn higher grades.If I attend classes regularly this semester,I should make higher grades than I did last semester when I often missed class.This is a ________.

Accepted Answer

The answer of After observing that students who regularly attend...

Question 14

Explain the self-correcting nature of science.

Accepted Answer

The answer of Explain the self-correcting nature of science....

Question 15

Land biomes are most commonly defined by

Accepted Answer

Land biomes are primarily defined by their climate and physical characteristics, which influence the types of plants that can thrive in them. These plants, in turn, affect the types of animals that can live in the biome, making climate and physical characteristics foundational to the definition of a biome.

Question 16

The genetic material used for reproduction by those organisms conventionally considered to be living is ________.

Accepted Answer

The answer of The genetic material used for reproduction by...

Question 17

When Dr. Blehert and his team set out to determine the cause of death for thousands of bats, they determined that the sick and dead bats had a strange white fuzz on their noses and wings along with depleted fat reserves and damaged wing tissue. After performing observational studies, the researchers used a branch of mathematics called ________ to quantify the reliability of their data.

Accepted Answer

The answer of When Dr. Blehert and his team set...

Question 18

What is the MOST likely explanation for why all living organisms use the same genetic code stored in DNA?

Accepted Answer

The fact that almost all living organisms use the same genetic code stored in DNA is a strong evidence of the common ancestor theory, which suggests that all life on Earth originated from a single ancestral organism that used DNA as its genetic material. As this organism multiplied and diversified, its descendants inherited the same genetic code and passed it on to their own offspring, creating a universal genetic code that all living organisms share.

Question 19

A small,potentially living object was found.For this object to be considered alive,the object must

Accepted Answer

The characteristic that all living things share is that they are composed of one or more cells. Therefore, for the small object to be considered alive it must contain one or more cells. None of the other options provided specifically address this characteristic of living things.

Question 20

DNA is one of the features common to all known forms of life; it

Accepted Answer

The answer of DNA is one of the features common...
