- B.
Variations in DNA, variations are inherited, offspring are born, only the fittest survive
- C.
Variations in living organisms, variations are inherited, too many offspring for environment to support, only the fittest survive
- D.
Variations in living organisms, variations in nonliving factors, too many offspring for environment to support, only the fittest survive
Correct Answer
C. Variations in living organisms, variations are inherited, too many offspring for environment to support, only the fittest surviveExplanation
The correct answer is "Variations in living organisms, variations are inherited, too many offspring for environment to support, only the fittest survive." This answer accurately describes the four steps of natural selection. First, there are variations in living organisms, meaning that individuals within a species have different traits. Second, these variations are inherited, meaning they can be passed down from parents to offspring. Third, there are typically more offspring produced than the environment can support, creating competition for resources. Finally, only the fittest individuals, those with traits that are advantageous in their environment, are able to survive and reproduce, passing on their favorable traits to future generations.Rate this question:

What is a differential reproductive success?
- A.
Every time an organism mates, it will differ in its success
- B.
Mating in organisms causes mutations, resulting in evolution
- C.
Your mom.
- D.
An organism survives, mates, and its offspring look like it
Correct Answer
D. An organism survives, mates, and its offspring look like itExplanation
Differential reproductive success refers to the variation in the number of offspring produced by different individuals within a population. It means that some organisms are more successful in reproducing and passing on their genes to the next generation, while others are less successful. This variation in reproductive success is a key driving force of evolution, as it leads to the accumulation of beneficial traits in a population over time.Rate this question:

- C.
Homeostasis where the end product stimulates the process
- D.
Homeostasis where the end product turns the process on and off randomly
Correct Answer
C. Homeostasis where the end product stimulates the processExplanation
Positive feedback is a type of homeostasis where the end product of a process stimulates or enhances the same process. In this type of feedback, the response amplifies the initial stimulus, leading to a cascade of events that further increases the response. This can result in a rapid and exponential growth or change in the system. Positive feedback is often seen in processes like blood clotting, childbirth, and the release of hormones. It helps to quickly and efficiently achieve a specific goal or outcome.Rate this question:
-
- 33.
Name an example of positive feedback.
- A.
Eating food
- B.
Child birth
- C.
Pain
- D.
Body temperature
Correct Answer
B. Child birthExplanation
Childbirth is an example of positive feedback because it is a process in which the body amplifies a specific action to achieve a desired outcome. During childbirth, contractions of the uterus increase in intensity and frequency, stimulating the release of oxytocin, which in turn causes stronger contractions. This positive feedback loop continues until the baby is born. The more intense the contractions, the more oxytocin is released, leading to even stronger contractions. This process demonstrates how positive feedback can amplify a physiological response to achieve a specific goal.Rate this question:
-
- 34.
What is negative feedback?
- A.
Homeostasis where the end product stops the process
- B.
Homeostasis that is really bad
- C.
Homeostasis where the end product turns the process on and off at random
- D.
Homeostasis where the end product stimulates the process
Correct Answer
A. Homeostasis where the end product stops the processExplanation
Negative feedback is a regulatory mechanism in homeostasis where the end product of a process inhibits or stops the process itself. This helps maintain a stable internal environment by preventing excessive production or activity. In this case, the correct answer states that negative feedback involves homeostasis where the end product stops the process.Rate this question:

- D.
Do not connect the points and use best smooth line
Correct Answer
D. Do not connect the points and use best smooth lineExplanation
After marking the points on a graph, the best practice is to not connect the points and instead use a best smooth line. Connecting the points directly may not accurately represent the data and can lead to misleading interpretations. Using a best smooth line helps to visualize the trend or pattern in the data without implying a direct connection between the points. This allows for a more accurate representation of the data and better analysis.Rate this question:

What is an example of negative feedback?
- A.
Child birth
- B.
None of These
- C.
Body temperature
- D.
Both A and C
Correct Answer
C. Body temperatureExplanation
Negative feedback refers to a regulatory mechanism in which the body responds to a stimulus by counteracting it, maintaining homeostasis. Body temperature is an example of negative feedback because when the temperature rises above normal, the body initiates mechanisms to cool down, such as sweating and dilation of blood vessels. Conversely, when the temperature drops below normal, the body triggers mechanisms to generate heat, such as shivering and constriction of blood vessels. This feedback loop helps maintain a stable body temperature. Childbirth and "None of These" do not exemplify negative feedback as they do not involve a regulatory response to a stimulus.Rate this question:
