Which experimental scenario would likely produce the most trustworthy results?
- A.
A blind experiment testing the effects of caffeine on blood pressure
- B.
An unbiased investigation that shows a strong correlation between two variables
- C.
A double-bling study involving a new heart disease treatment
- D.
An experiment that is slightly biased but does not use a model organism
Correct Answer
C. A double-bling study involving a new heart disease treatmentExplanation
A double-blind study involving a new heart disease treatment would likely produce the most trustworthy results. In a double-blind study, neither the participants nor the researchers know which treatment is being administered, reducing the chances of bias or subjective influence on the results. This helps to ensure that the results obtained are objective and reliable. Additionally, studying a new heart disease treatment adds to the importance of conducting a study with rigorous protocols to ensure accurate and trustworthy results.Rate this question:

When a hypothesis is extensively tested and supported by a large number of studies conducted by many different scientists, then
- A.
The hypothesis is referred to as a prediction.
- B.
it is considered a scientific theory.
- C.
Further experimentation will not occur unless an alternative hypothesis is proposed.
- D.
It is a fact that cannot be refuted.
Correct Answer
B. it is considered a scientific theory.Explanation
When a hypothesis is extensively tested and supported by a large number of studies conducted by many different scientists, it is considered a scientific theory. This is because a scientific theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has been repeatedly confirmed through experimentation and observation. A hypothesis, on the other hand, is an educated guess or a proposed explanation for a phenomenon that can be tested through experimentation. Therefore, when a hypothesis has been extensively tested and supported by numerous studies, it becomes a scientific theory.Rate this question:

Which of the following is not a defense mechanism evolved in plants?
- A.
Spines of bamboo
- B.
Spines in cacti
- C.
Thorns in roses
- D.
Pollens of cedars
Correct Answer
D. Pollens of cedarsExplanation
The pollens of cedars are not a defense mechanism evolved in plants. Defense mechanisms in plants usually involve physical structures such as spines, thorns, or prickles, which deter herbivores from feeding on them. Pollens, on the other hand, are reproductive structures produced by plants for the purpose of fertilization and propagation, rather than defense.Rate this question:

Where does the oxygen that we breath come from?
- A.
Plants only
- B.
Algae and cyanobacteria only
- C.
Plants, algae, and cyanobacteria
- D.
Plants and algae only
- E.
Algae only
Correct Answer
C. Plants, algae, and cyanobacteriaExplanation
Plants, algae, and cyanobacteria are responsible for producing the oxygen that we breathe. Through a process called photosynthesis, these organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. This oxygen is then released into the atmosphere as a byproduct of photosynthesis. Therefore, plants, algae, and cyanobacteria are the primary sources of oxygen in our environment.Rate this question:

Why are hypothesis never accepted by scientists?
- A.
Experimentation cannot support a hypothesis because it only tests predictions.
- B.
Alternative hypotheses might provide a better answer to the research question.
- C.
A hypothesis cannot ever be true or false because it is an opinion.
- D.
Hypotheses change every time a new experiment is conducted.
Correct Answer
B. Alternative hypotheses might provide a better answer to the research question.Explanation
Scientists never accept hypotheses because alternative hypotheses might provide a better answer to the research question. This means that scientists are always open to new ideas and possibilities, and they understand that there may be other explanations or theories that can better explain the observed phenomenon. Therefore, they continue to explore and test different hypotheses to gain a deeper understanding of the subject matter.Rate this question:

People with type O blood are natural meat eaters.
- C.
Peacocks like to display their large tail feathers.
- D.
Bees can see ultraviolet light that humans can't.
Correct Answer
D. Bees can see ultraviolet light that humans can't.Explanation
The hypothesis that bees can see ultraviolet light that humans can't is testable using scientific methods. This hypothesis can be tested by conducting experiments that compare the visual abilities of bees and humans, such as using specialized equipment to measure the wavelengths of light that bees and humans can detect. The results of these experiments can provide evidence to support or refute the hypothesis.Rate this question:

Consider this hypothesis: "Drinking Echinacea tea reduces the duration and severity of colds." Which of the following statements is the best prediction based on this hypothesis?
- A.
If a person doesn't drink Echinacea tea, then he or she will catch a cold very easily.
- B.
If people with a cold drink Echinacea tea, then they will feel better sooner than people who don't consume the tea.
- C.
If people with a cold drink Echinacea tea, then the tea will reduce their stress, making them feel better.
- D.
If people with a cold drink Echinacea tea, then an ingredient in the tea will bind to cold viruses and destroy them.
Correct Answer
B. If people with a cold drink Echinacea tea, then they will feel better sooner than people who don't consume the tea.Explanation
The correct answer is "If people with a cold drink Echinacea tea, then they will feel better sooner than people who don't consume the tea." This prediction is based on the hypothesis that drinking Echinacea tea reduces the duration and severity of colds. By drinking the tea, it is expected that individuals will experience a faster recovery compared to those who do not consume the tea.Rate this question:

A scientific hypothesis has which of the following features?
- A.
It is falsifiable.
- B.
It is not based on observations.
- C.
It is a theory about something.
- D.
It is a theory about something.
Correct Answer
A. It is falsifiable.Explanation
A scientific hypothesis has the feature of being falsifiable, meaning that it can be tested and potentially proven false through experimentation or observation. This is an important characteristic because it allows scientists to gather evidence and data to support or refute the hypothesis, leading to the development of new theories and understanding in the scientific field.Rate this question:

Suppose that a botanist is interested in the effect of light on plants. In an experiment she conducts, 50 individuals of a single species of flowering plant are grown for 60 days under different lengths of artificial daylight. The plant species has flowers that can be either white or pink, depending on the genetics of the parent plants. The amount of water and fertilizer provided to each plant is constant. At the end of the experiment, the size of each leaf of every plant is measured. The dependent variable in this experiment is the
- A.
Flowers Color
- B.
Duration of artificial daylight
- C.
Leafs Size
- D.
Duration of the experiment
Correct Answer
C. Leafs SizeExplanation
The dependent variable in this experiment is the size of each leaf of every plant. This is because the botanist wants to measure the effect of light on plants, and the size of the leaves can indicate how well the plants have grown under different lengths of artificial daylight. The other options, such as flower color, duration of artificial daylight, and duration of the experiment, are not the main focus of the study and are not being directly measured.Rate this question:

A researcher has hypothesized that the chemical tributyltin (an additive in boat paint) seeps out of the paint into the water and causes reproductive defects in developing marine snails. Which of the following would be a good control in an experiment that tests the effects of tributyltin on developing snails?
- A.
Developing snails are kept in a tank of water that has never been exposed to boat paint.
- B.
Developing snails are kept in a tank of water and exposed to below-expected levels of tributyltin.
- C.
Developing snails are kept in a dry tank to avoid exposure to contaminated water.
- D.
Developing snails are kept in a tank of water and exposed to boat paint that does not contain tributyltin.
Correct Answer
D. Developing snails are kept in a tank of water and exposed to boat paint that does not contain tributyltin.Explanation
The correct answer is developing snails are kept in a tank of water and exposed to boat paint that does not contain tributyltin. This would be a good control because it allows the researcher to compare the effects of tributyltin on developing snails to the effects of other components in the boat paint. By using boat paint that does not contain tributyltin, any observed reproductive defects in the snails can be attributed to the presence of tributyltin and not other factors in the paint.Rate this question:

Which of the following is false about flowering plants?
- A.
They are called angiosperms
- B.
They do not produce seeds
- C.
They produce fruits
- D.
They have vascular tissues
- E.
They produce gametes
Correct Answer
B. They do not produce seedsExplanation
Flowering plants, also known as angiosperms, are true seed producers. They have specialized structures called ovaries that develop into fruits after fertilization. These fruits contain seeds, which are the reproductive structures of the plant. Additionally, flowering plants have vascular tissues that transport water, nutrients, and sugars throughout the plant. They also produce gametes, which are the reproductive cells involved in sexual reproduction. Therefore, the statement "They do not produce seeds" is false.Rate this question:

- A.
Plants
- B.
Fungi
- C.
Archea
- D.
Eubacteria
- E.
Animals
- F.
Protista
Correct Answer(s)
A. Plants
B. Fungi
E. Animals
F. ProtistaExplanation
Plants, fungi, animals, and protista all contain a nucleus in their cells. The presence of a nucleus is a defining characteristic of eukaryotic cells, which these groups of organisms belong to. The nucleus is a membrane-bound organelle that houses the cell's DNA and controls its activities. In contrast, archea and eubacteria are prokaryotes, which lack a nucleus and have their DNA floating freely in the cell.Rate this question:
