Storing and periodically releasing energy obtained from food is an example of...

Evolution
Response
Homeostasis
Growth

Correct Answer

A. Growth

Explanation

Storing and periodically releasing energy obtained from food is an example of growth because it involves the accumulation and utilization of energy to support the development and maintenance of an organism. Growth encompasses the processes of acquiring and storing nutrients, converting them into usable forms of energy, and using that energy for various physiological functions. In this case, the energy obtained from food is stored and released as needed to fuel the growth and functioning of the organism.

A hypothesis that is supported many times may become a

Experiment
Conclusion
Theory
Observation

Correct Answer

A. Theory

Explanation

When a hypothesis is supported many times through repeated experiments and observations, it may become a theory. A theory is a well-substantiated explanation of a phenomenon that is based on a large body of evidence. It goes beyond a single observation or experiment and provides a comprehensive framework for understanding and predicting a particular aspect of the natural world. The development of a theory requires rigorous testing and validation of the hypothesis through multiple lines of evidence. Therefore, a hypothesis that is supported many times can evolve into a theory.

All of the procedures scientists use to answer questions are

Life characteristics
Research
Scientific methods
Hypotheses
Stupid

Correct Answer

A. Scientific methods

Explanation

The correct answer is "Scientific methods" because scientists use a systematic approach to answer questions and solve problems. They follow a series of steps, such as making observations, formulating hypotheses, conducting experiments, analyzing data, and drawing conclusions. This process is known as the scientific method and is essential for obtaining reliable and valid results in scientific research. The other options, such as "Life characteristics," "Research," "Hypotheses," and "Stupid," are not accurate explanations for the procedures scientists use.

The environment includes

Air, water, and weather
Response to a stimulus
Adaptations
Evolution

Correct Answer

A. Air, water, and weather

Explanation

The environment includes air, water, and weather because these elements are essential components of the natural surroundings in which organisms live. Air provides the necessary oxygen for respiration, water is crucial for survival and various physiological processes, and weather conditions such as temperature and precipitation affect the availability of resources and influence the behavior and distribution of organisms. Therefore, these factors play a significant role in shaping the environment and influencing the adaptations and evolution of living organisms.

Which of the following is NOT a testable hypothesis?

Fertilizer A will make the KW variety of green bean produce more beans.
Smart people like the same music.
Vitamin C relieves cold symptoms.
There is more than one species of African elephant.

Correct Answer

A. Smart people like the same music.

Explanation

A hypothesis is considered testable if it can be measured or observed through experimentation or data collection. "Smart people like the same music" is not a testable hypothesis because it lacks clear, measurable criteria for "smartness" and "liking the same music." Both "intelligence" and "musical preference" are subjective and difficult to quantify or standardize for a scientific experiment.
On the other hand, the other hypotheses, such as the impact of fertilizer on bean production, the effects of vitamin C on cold symptoms, and the classification of African elephant species, can be tested through measurable observations, making them valid testable hypotheses.

Which plot is the control group?

The first plot with traditional pesticide.
The second plot with the new pesticide.
The third plot with no pesticide
There is no control group.

Correct Answer

A. The third plot with no pesticide

Explanation

The control group is the group that does not receive any treatment or intervention, in order to compare the effects of the treatment. In this case, the control group is the third plot with no pesticide. This is because the first plot with traditional pesticide and the second plot with the new pesticide are both receiving some form of treatment, while the third plot is the only one that is not being treated with any pesticide.

What could be concluded if the plot treated with the new pesticide has damage similar to the control plot?

The experiment is a failure
The new pesticide may not be effective.
The control plot was problematic
The new pesticide should be used.

Correct Answer

A. The new pesticide may not be effective.

Explanation

If the plot treated with the new pesticide has damage similar to the control plot, it suggests that the new pesticide may not be effective. This is because if the pesticide was effective, it would have resulted in less or no damage compared to the control plot. Therefore, the similarity in damage indicates that the new pesticide did not have the desired effect in protecting the plants.
