Why are the gene pools of small populations reduced compared to those of larger populations?
a
inbreeding
b
lack of advantageous traits
c
lack of suitable mates
d
bottleneck events
The correct answer is d. bottleneck events. When a small population undergoes a bottleneck event, it loses genetic variation, and certain alleles may be lost or become fixed at higher frequencies due to chance. This results in a smaller gene pool, which means there are fewer variations in the gene pool of the population as a whole. Inbreeding (a) may contribute to the reduction of genetic diversity, but it is not the primary reason why the gene pools of small populations are reduced compared to larger populations. A lack of advantageous traits (b) or suitable mates (c) may limit the adaptation of a population, but they are not directly related to the reduction of genetic variation in a population.
Consider the following scenario: A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. Drought has little effect on insect populations.
What is the main selective pressure in this scenario?
a
drought
b
insect population
c
leg length
d
fish population
The main selective pressure in this scenario is d. fish population. The drought and the consequent decline in fish populations exert selective pressure on the long-legged birds that eat fish. As fish become less available, the long-legged birds that can reach deeper into the remaining water pools to catch fish have an advantage over the short-legged birds that rely on insects. Over time, the proportion of long-legged birds in the population is likely to increase as a result of natural selection. Thus, the selection pressure on leg length is a consequence of the selective pressure on fish availability. The insect population (b) is not affected by the drought, and thus, it is not a selective pressure. While the drought itself (a) may be a stressor for the entire population, it is not the main selective pressure acting on the bird population.
Consider the following scenario: You notice that no two cats at the pet store are exactly alike. Some have spotted fur. Some have striped fur. Some have fur of one solid color. What term is used to describe your observation?
a
variation
b
fitness
c
natural selection
d
selective pressure
The term used to describe this observation is a. variation. Variation refers to the differences that exist between individual organisms within a population or species, such as different fur patterns in cats. This variation is caused by genetic differences between individuals and can be influenced by environmental factors as well. Variation is an important concept in biology and is a necessary condition for evolution and natural selection to occur. Fitness (b) refers to an organism's ability to survive and reproduce in its environment. Natural selection (c) is a mechanism of evolution in which certain traits become more or less common in a population over time due to differential reproductive success. Selective pressure (d) refers to any factor in the environment that affects an organism's fitness and can lead to natural selection.
i jut want to know if it is
a natural selection
b fitness
c mutation
or d selective pressures
Consider the following scenario: In an aquatic bird population, some birds have long legs. Other birds have short legs. The food supply is minimal. The birds with long legs are able to wade farther into the water where they can find fish. Over time, the birds with long legs become more common. What scientific term best describes this scenario?
a
natural selection
b
fitness
c
mutation
d
selective pressures
The best scientific term that describes this scenario is a. natural selection. Natural selection is the mechanism by which certain traits become more or less common in a population over time due to differential reproductive success. In this scenario, the bird population is subject to selective pressures due to the limited food supply. Birds with long legs have an advantage as they can reach the deeper waters where they can find more fish, which gives them better chances to survive and successful reproduce. Therefore, over time, the frequency of the long-legged birds in the population increases as a result of natural selection. Fitness (b) refers to an organism's ability to survive and reproduce in its environment. Mutation (c) is a genetic variation that can lead to new traits, but it is not directly applicable in this scenario. Selective pressures (d) are factors in the environment that can affect an organism's fitness and lead to natural selection, but it is not the scientific term that best describes the scenario.

What statement accurately describes the relationship between variations and fitness?
a
Variations always increase fitness.
b
Variations can lead to either an increase or decrease in fitness.
c
Fitness always increases variations
d
Fitness can lead to either an increase or decrease in variations.
The statement that accurately describes the relationship between variations and fitness is b. Variations can lead to either an increase or decrease in fitness.
Variation refers to the differences that exist between individual organisms within a population or species, such as differences in morphology, physiology, or behavior. Fitness, on the other hand, refers to an organism's ability to survive and reproduce in its environment.
Variations may have varying effects on fitness, depending on the specific environment and selective pressures acting on the population. Some variations may increase an organism's fitness, allowing it to better survive and reproduce, while other variations may decrease an organism's fitness, making it less competitive or less able to survive in its environment.
Therefore, although some variations may increase fitness, variations can lead to either an increase or decrease in fitness, depending on how well they help an organism survive and reproduce in its environment.
1) How did the Industrial Revolution impact the population of peppered moths in Britain?
a
The light-colored moths became more common.
b
The Industrial Revolution caused the proportions of each color morph in the population to become unequal
c
The dark-colored moths became more common.
d
The Industrial Revolution caused the proportions of each color morph in the population to become equal.
2) Which explanation is accurate about the survival and reproduction of a population?
a
If there are a limited variety of traits in a population, most traits will be a good fit with the environment.
b
If there are a limited variety of traits in a population, it is more likely that some individuals will be able to survive and reproduce.
c
If there are a wide variety of traits in a population, most traits will be a good fit with the environment.
d
If there are a wide variety of traits in a population, it is more likely that some individuals will be able to survive and reproduce.
3) Which variety of mouse is more likely to survive in a dry desert?
a
a mouse that needs more water
b
a mouse that needs less water
c
a mouse that has a shorter tail
d
a mouse that has a longer tail
1) The correct answer is c. The dark-colored moths became more common. During the Industrial Revolution, air pollution caused trees to darken, making it harder for light-colored moths to remain camouflaged against predators. As a result, the dark-colored moths became more common in the population.
2) The correct answer is d. If there are a wide variety of traits in a population, it is more likely that some individuals will be able to survive and reproduce. Diversity of traits promotes the ability of a population to adapt to changing environmental pressures. This is because some individuals in the population may possess traits that are better suited for the environment and as a result, they are more likely to survive and reproduce.
3) The correct answer is b. A mouse that needs less water is more likely to survive in a dry desert. This is because a desert environment has limited water resources, and a mouse that requires less water is more able to meet its water needs from the available resources. The length of the tail of the mouse (c and d) is not directly related to survival in a desert environment. Although water requirements may influence survival in a desert, the question does not provide enough information to indicate how much water the two varieties of mouse require (a and b).
