All types of living things do each of the following except
-
Grow and develop
-
Reproduce
-
Destroy the environment
-
Respond to stimuli
Correct Answer
A. Destroy the environmentExplanation
Living things do not destroy the environment. They are a part of the environment and interact with it, but they do not intentionally cause harm or damage to it. Instead, living things are dependent on the environment for their survival and often have adaptations that allow them to live in harmony with their surroundings. Destruction of the environment is typically caused by human activities or natural disasters, not by the inherent nature of living organisms.Rate this question:

Energy flows through an ecosystem from the sun to
-
Producers and then consumers
-
Consumers and then producers
-
Primary consumers
-
Secondary consumers
Correct Answer
A. Producers and then consumersExplanation
Energy flows through an ecosystem from the sun to producers and then to consumers. This is because producers, such as plants, use sunlight to convert it into chemical energy through photosynthesis. This energy is then passed on to consumers, such as herbivores, which eat the producers. Consumers further transfer this energy to other consumers in the food chain, such as carnivores or omnivores. Therefore, the flow of energy starts with producers and then moves to consumers in an ecosystem.Rate this question:

Lucie wanted to confirm the statement that pepsin is needed in addition to hydrochloric acid to digest protein in the stomach. He placed equal-sized pieces of egg white (protein) and equal amounts of diluted hydrochloric acid in each of 4 test tubes. Then he added a pinch of pepsin to test tubes C and D. He placed all 4 test tubes in a warm place overnight. The next day, two of the test tubes were milky white. What is the variable in the experiment described here?
-
Location of the tubes
-
Concentration of hydrochloric acid
-
Size of the egg whites
-
Presence of pepsin
Correct Answer
A. Presence of pepsinExplanation
In this experiment, Lucie is investigating the role of pepsin in digesting protein in the stomach. The variable being tested is the presence of pepsin. Test tubes C and D were the ones that had pepsin added to them, while the other test tubes did not have pepsin. The fact that only two of the test tubes turned milky white suggests that the presence of pepsin is necessary for the digestion of protein, as the test tubes without pepsin did not show the same result. Therefore, the variable in this experiment is the presence of pepsin.Rate this question:

The end result of ecological succession is usually
-
A climax community
-
An unstable community
-
An aquatic biome
-
A land biome
Correct Answer
A. A climax communityExplanation
Ecological succession refers to the process of change in the structure and composition of an ecological community over time. It involves a series of stages, starting from a disturbed or barren area, leading to the establishment of a stable and diverse community. The final stage of ecological succession, known as the climax community, represents a state of equilibrium where the community has reached its fullest potential and is able to sustain itself. Therefore, the end result of ecological succession is usually a climax community.Rate this question:

Primary consumers are also known as
-
Carnivores
-
Decomposers
-
Herbivores
-
Scavengers
Correct Answer
A. HerbivoresExplanation
Primary consumers are organisms that feed on plants and other autotrophs, obtaining their energy directly from the producers in an ecosystem. This means that they are herbivores, as they primarily consume plant material. Carnivores are organisms that feed on other animals, decomposers break down dead organic matter, and scavengers consume dead animals. Therefore, the correct answer is herbivores.Rate this question:

The distinct zones of the ocean depend upon
-
Distance from shore and temperature
-
Distance from shore and depth
-
Temperature and types of organisms
-
Types of organisms and distance from shore
Correct Answer
A. Distance from shore and depthExplanation
The distinct zones of the ocean depend on the distance from shore and depth. This is because as you move further away from the shore, the depth of the ocean increases, leading to different environmental conditions. Different depths have different amounts of sunlight, pressure, and temperature, which in turn affect the types of organisms that can survive in each zone. Therefore, both distance from shore and depth play a crucial role in determining the distinct zones of the ocean.Rate this question:

Exponential growth is the phase in which a population
-
Reaches a carrying capacity
-
Grows quickly and few animals die
-
Growth begins to slow down
-
Growth stops
Correct Answer
A. Grows quickly and few animals dieExplanation
Exponential growth is a phase in which a population grows quickly and few animals die. This means that the population is increasing rapidly and there are minimal deaths occurring within the population. As a result, the population continues to expand at an accelerated rate. However, it is important to note that this phase will eventually reach a carrying capacity, at which point the growth will begin to slow down and eventually stop.Rate this question:

The process of science starts with
-
A hypothesis
-
A conclusion
-
An observation
-
A theory
Correct Answer
A. An observationExplanation
The process of science begins with an observation because observations are the initial step in gathering information and identifying patterns or phenomena that need to be explained. Observations serve as the foundation for formulating hypotheses, which are educated guesses or predictions about the cause or explanation of the observed phenomenon. From there, scientists can conduct experiments or gather further evidence to test their hypotheses and ultimately develop theories that provide a comprehensive explanation for the observed phenomena.Rate this question:

-
Mutualism
-
Symbiosis
-
Predation
Correct Answer
A. SymbiosisExplanation
Symbiosis refers to a close and long-term interaction between two different species, where at least one species benefits. Parasitism is a type of symbiosis where one species, the parasite, benefits at the expense of the other species, the host. This relationship is characterized by the parasite relying on the host for resources, such as food or shelter, while causing harm or damage to the host. Therefore, symbiosis is the correct answer as it encompasses the concept of parasitism within its definition.Rate this question:

Correct Answer
A. Biogeochemical cyclesExplanation
Biogeochemical cycles refer to the movement of nutrients through the biosphere, involving both living organisms and the physical environment. These cycles include the carbon cycle, nitrogen cycle, and water cycle, among others. In these cycles, nutrients are taken up by organisms, transferred through food chains, released back into the environment through decomposition, and eventually recycled. This process is essential for maintaining the balance of nutrients in ecosystems and ensuring the availability of essential elements for all living organisms.Rate this question:

The various growth phases through which most populations go are represented on
-
A logistic growth curve
-
An exponential growth curve
-
A normal growth curve
-
A boom and bust curve
Correct Answer
A. A logistic growth curveExplanation
The correct answer is a logistic growth curve. A logistic growth curve represents the various growth phases that most populations go through. It starts with a slow initial growth phase, then transitions into a rapid exponential growth phase, and finally reaches a stable phase where the population size levels off due to limited resources. This curve is commonly used to model population growth and is characterized by an S-shaped curve.Rate this question:
