A hypothesis is formulated using which type of reasoning?
- A.
Deductive
- B.
Inductive
- C.
Didactic
Correct Answer
B. InductiveExplanation
A hypothesis is formulated using inductive reasoning. Inductive reasoning involves making generalizations or predictions based on specific observations or evidence. In this case, a hypothesis is formed by observing specific phenomena or patterns and then inferring a general statement or prediction about the relationship between those phenomena. Deductive reasoning, on the other hand, involves drawing specific conclusions from general principles or theories, which is not the process used in formulating a hypothesis. Didactic reasoning is not a type of reasoning used in formulating hypotheses.Rate this question:

Why might a scientist modify his or her hypothesis?
- A.
He results of an experiment are not consistent with the hypothesis.
- B.
He results are consistent with a long-standing, but umpopular theory.
- C.
Another, more senior scientist does not like the results because they contradict his theory but are consistent with the one being tested.
- D.
The results are consistent with the hypothesis.
Correct Answer
A. He results of an experiment are not consistent with the hypothesis.Explanation
A scientist might modify his or her hypothesis if the results of an experiment are not consistent with the hypothesis. This is because the purpose of conducting an experiment is to test the validity of the hypothesis, and if the results do not support it, then the scientist needs to revise the hypothesis to better align with the observed data. Modifying the hypothesis allows the scientist to refine their understanding of the phenomenon being studied and develop a more accurate explanation.Rate this question:

- A.
The are the same meaning to both.
- B.
They are both words used as synonyms for technology but in a different sense by scientists and the lay public.
- C.
Scientists view a theory as a rigorously tested hypothesis with broad explanatory power; the lay pblic views a theory as an "imperfectly known fact" or a guess.
- D.
Both groups view a theory as a guess that has little support, but scientists view it as based on physical evidence, while the public views it as based on withful thinking.
Correct Answer
C. Scientists view a theory as a rigorously tested hypothesis with broad explanatory power; the lay pblic views a theory as an "imperfectly known fact" or a guess.Explanation
Scientists and the lay public have different views on the word "theory." Scientists consider a theory to be a hypothesis that has undergone rigorous testing and has the ability to explain a wide range of phenomena. On the other hand, the lay public sees a theory as an "imperfectly known fact" or simply a guess. While scientists base their understanding of a theory on physical evidence, the public tends to view it as wishful thinking.Rate this question:

- D.
Anything other than the treatment that could differ between the experimental and control groups
Correct Answer
D. Anything other than the treatment that could differ between the experimental and control groupsExplanation
A controlled variable in an experiment refers to anything other than the treatment that could differ between the experimental and control groups. This means that all aspects of the experiment, except for the treatment being tested, should be kept constant in order to accurately assess the effects of the treatment. By controlling variables such as time, temperature, or other conditions, researchers can isolate the impact of the treatment and determine its specific effects on the experimental group compared to the control group.Rate this question:

Which of the following is NOT an assumption made by science?
- A.
The universe exists
- B.
The universe can be rationally studied
- C.
physical laws explain natural phenomena
- D.
Supernatural forces can alter physical effects
Correct Answer
D. Supernatural forces can alter physical effectsExplanation
Science is based on the assumption that the universe exists and can be rationally studied. It also assumes that physical laws can explain natural phenomena. However, science does not assume that supernatural forces can alter physical effects. This is because science relies on empirical evidence and the scientific method, which focuses on natural explanations for observable phenomena. Supernatural forces, by definition, are beyond the scope of scientific inquiry as they cannot be tested or observed in a systematic and repeatable manner.Rate this question:

- C.
Carrying capacity can be set by a single limiting factor.
- D.
Carrying capacity determines what limiting factors occur in a population.
Correct Answer
C. Carrying capacity can be set by a single limiting factor.Explanation
Carrying capacity refers to the maximum number of individuals that an environment can sustainably support. Limiting factors, on the other hand, are factors that restrict the growth or distribution of a population. The given answer suggests that a single limiting factor can determine the carrying capacity of a population. This means that if a specific factor, such as food availability or habitat space, becomes limited, it can directly affect the carrying capacity by setting a maximum limit on the population size that can be supported.Rate this question:

Which of the following describes a type III survivorship pattern?
- A.
a constant mortality rate over the life of the cohort
- B.
Low infant mortality with a high probability of living to old age
- C.
Low infant, high middle age, and low old age mortality
- D.
High infant mortality with a low probability of living to old age
Correct Answer
D. High infant mortality with a low probability of living to old ageExplanation
A type III survivorship pattern is characterized by high infant mortality with a low probability of living to old age. This means that a large number of individuals in the cohort die at a young age, particularly during infancy, and only a small percentage of individuals survive to reach old age. The mortality rate decreases as individuals reach middle age, but then increases again in old age. This pattern is commonly observed in species with large numbers of offspring and little parental care, where survival is primarily determined by external factors such as predation or environmental conditions.Rate this question:

What is the role of decomposers in nutrient cycling?
- A.
To turn chemical energy to heat energy
- B.
to recycle minerals to the reservoir for re-use by primary producers
- C.
To release minerals directly back to the consumers
- D.
to make new minerals for use in nutrient cycling
Correct Answer
B. to recycle minerals to the reservoir for re-use by primary producersExplanation
Decomposers play a crucial role in nutrient cycling by breaking down organic matter and releasing nutrients back into the environment. As they decompose dead plants and animals, they recycle minerals, such as nitrogen, phosphorus, and carbon, back into the soil or water. These minerals are then available for uptake by primary producers, such as plants, to use in their growth and development. Therefore, decomposers help to maintain a continuous supply of essential nutrients in the ecosystem by returning them to the reservoir for reuse by primary producers.Rate this question:

Biological magnification occurs because
- A.
The biomass decreases by 90% from each trophic level to trophic level
- B.
Toxic substances can enter the food web at the producer level that are absorbed and stored but not excreted by the producers and then the consumer levels
- C.
At higher trophic levels, toxins build up to a concentration high enough to cause harm to the organisms
- D.
All of the above, answer 1, 2, and 3 contribute to biological magnification
Correct Answer
D. All of the above, answer 1, 2, and 3 contribute to biological magnificationExplanation
Biological magnification occurs because as organisms consume other organisms, the toxins present in the prey accumulate in the predator's body. This accumulation happens because the biomass decreases by 90% from each trophic level to the next, leading to a higher concentration of toxins in each successive level. Additionally, toxic substances can enter the food web at the producer level and be absorbed and stored by the producers without being excreted. These toxins then get transferred to the consumers at higher trophic levels, where they continue to accumulate to a concentration high enough to cause harm to the organisms. Therefore, all three factors mentioned in answers 1, 2, and 3 contribute to biological magnification.Rate this question:

- B.
Seasonality
- C.
Oceanic circulation gyres
- D.
Hadley cells
Correct Answer
B. SeasonalityExplanation
The Earth tilts at 23 degrees on its axis, which causes seasonality. This tilt means that different parts of the Earth receive varying amounts of sunlight throughout the year, leading to the changing of seasons. As the Earth orbits the Sun, the tilt causes the angle at which sunlight hits different regions to change, resulting in variations in temperature, weather patterns, and the length of daylight. This phenomenon is responsible for the distinct seasons experienced in different parts of the world.Rate this question:

Coral Reeds
Correct Answer
C. PhoticExplanation
Algae live in the photic zone of marine ecosystems. The photic zone is the upper layer of the ocean where sunlight can penetrate, allowing for photosynthesis to occur. Algae require sunlight for photosynthesis, so they are found in this zone where they can receive adequate light. The other options, such as pelagic, benthic, aphotic, intertidal, and coral reefs, do not specifically refer to the zone where algae live.Rate this question:

Correct Answer(s)
A. Pelagic
C. PhoticExplanation
Pelagic refers to the open water area of a body of water, away from the shore or bottom. Zooplankton, which are small animals that float in the water, typically inhabit the pelagic zone. The term "photic" refers to the zone in a body of water where sunlight can penetrate and support photosynthesis. Therefore, the correct answer "Pelagic, Photic" suggests that the area being described is the open water zone where zooplankton live and where sunlight can reach.Rate this question:

Coral Reeds
Correct Answer
D. AphoticExplanation
The term "aphotic" refers to a zone in the ocean where there is no sunlight penetration. This zone is characterized by complete darkness and is located below the photic zone, where sunlight can reach. In this zone, there is no photosynthesis occurring, so there is a lack of primary producers such as algae or plants. As a result, the aphotic zone is generally inhabited by organisms that can survive in low-light or no-light conditions, such as deep-sea fish, certain types of bacteria, and other organisms that rely on chemosynthesis rather than photosynthesis for energy.Rate this question:

Correct Answer
B. BenthicExplanation
The correct answer is "Benthic". Benthic refers to the bottom of a body of water, including the sediment and organisms that live there. Inhabited by bottomfeeders suggests that the area being described is the bottom part of the water, where organisms that feed on the sediment or other organisms on the bottom are found. Therefore, "Benthic" is the most suitable term to describe this habitat.Rate this question:

Coral Reeds
Correct Answer
D. AphoticExplanation
The term "aphotic" refers to a zone or area in a body of water that lacks sunlight and is therefore unable to support photosynthesis. In this context, the statement "inhabited by bottomfeeders" suggests that the area being referred to is a deep, dark region of the ocean where light does not penetrate. This is consistent with the characteristics of the aphotic zone, which is located below the photic zone where sunlight can reach.Rate this question:

Correct Answer
E. IntertidalExplanation
Intertidal refers to the area that is exposed to air during low tide and submerged during high tide. This zone is characterized by the interface between land and water, making it the correct answer. Pelagic refers to the open ocean, benthic refers to the ocean floor, photic refers to the zone where sunlight can penetrate, aphotic refers to the zone where sunlight cannot penetrate, and coral reefs are a specific type of marine habitat.Rate this question:

Correct Answer
E. IntertidalExplanation
The correct answer is "Intertidal" because the term "intertidal" refers to the area between the high and low tide marks, where organisms are exposed to both air and water. This habitat is characterized by constant changes in water levels and conditions, which makes it suitable for sedentary organisms that can adapt to these fluctuations.Rate this question:
