Immigration of individuals to a population in Hardy-Weinberg equilibrium will NOT upset the equilibrium if?

the immigrants do not introduce new alleles to the population and do not have a significantly different allele frequency from the existing population. Additionally, the immigrants must not change the population size significantly by either increasing or decreasing it.


What does a negative growth rate indicate for a population?

A negative growth rate indicates that the population is decreasing in size over time. This may be due to factors such as low birth rates, high death rates, emigration, or other demographic factors. It can have implications for the economy, workforce, and overall health of the population.


Look at the prey's population size at the end of the graph. How will this population size most likely change next?

The prey population size at the end of the graph appears to be decreasing, indicating a likely continued decline in the population size in the near future. This could be due to factors such as predation, resource depletion, or environmental changes impacting the prey species.


What does a negative growth rate signify in microbiology and how does it impact the overall microbial population dynamics?

A negative growth rate in microbiology signifies that the population of microorganisms is decreasing over time. This can impact the overall microbial population dynamics by leading to a decline in the number of microorganisms present, potentially affecting the ecosystem and interactions within it.


What is the primary factor in decreaseing the kinetic energy of an object?

The primary factor in decreasing the kinetic energy of an object is applying an external force in the direction opposite to its motion, which results in negative work being done on the object. This reduces its speed and kinetic energy.
