How do differences between individuals and environments affect natural selection?
Differences between individuals may affect differences in their average reproductive success, causing the variant traits of individuals that have greater reproductive success (fitness) to become more prevalent in a given environment than rival traits. As environments change, so may the traits that have a reproductive advantage change. This is natural selection.
What do studies indicate about very small populations?
the # of individuals in a population, or population size, can affect the population's ability to servive.
How does reproductive isolation affect the gene pools of two or more population?

4 factors that affect the growth rate of a population?
Birth rate: The number of individuals being born into the population. Death rate: The number of individuals dying in the population. Immigration: The movement of individuals into the population. Emigration: The movement of individuals out of the population.
How can cooperative behavior affect an individuals reproductive success?
Cooperative behavior can increase an individual's reproductive success by allowing them to form alliances with others to access resources, defend against predators, or increase their chances of finding a mate. By cooperating, individuals can share the burden of tasks, improve their overall fitness, and increase the survival of offspring by working together to raise them. Additionally, cooperation can lead to social bonds that provide support and increase an individual's social status, making them more attractive to potential mates.
Identify how a limited resource can affect the size of a population?
A limited resource can affect the size of a population by creating competition among individuals for access to that resource. If the resource is essential for survival and reproduction, such as food or water, the population size may be constrained by the availability of the resource. This can lead to increased mortality rates, decreased reproductive success, and ultimately a smaller population size.
What must be true of all characteristics for it to affect evolution?
For a characteristic to affect evolution, it must be heritable, meaning it can be passed down from one generation to the next. Additionally, the characteristic must influence the survival and reproductive success of individuals in a population. These two factors are essential for natural selection to operate and lead to evolutionary change.
How does development affect behavior?
Development can affect behavior by shaping a person's cognitive, emotional, and social skills. As individuals grow and learn, their experiences and interactions with the environment influence how they think, feel, and act. Developmental milestones, such as language acquisition or socialization, can impact how individuals respond to stimuli and engage in various activities.
What is an example of an open population in science?
a population where all 4 factors affect the population or Group of individuals organisms that belong to the same species that live in the same area
What are three things that could mess up the human reproductive system?
Infections in the human reproductive system could cause scarring. Cancer can affect the organs of the reproductive system. Hormonal disorders can affect the function of the reproductive system.
What are three factors that affect reproductive potential?
Three factors that affect reproductive potential include age (fertility declines with age), health (physical and reproductive health can impact fertility), and genetic factors (inherited conditions that may affect fertility).
How does the reproductive system affect your health?
