a. The birthrate becomes higher than the Death Rate.
b. The birthrate stays the same and the Death Rate increases.
c. The birthrate becomes lower than the death rate.
d. The birthrate and the death rate remain the same.
For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.
A population must be isolated in some way
mating must happen randomly
A genetic mutation within the population.
a. The birthrate becomes higher than the death rate. b. The birthrate stays the same and the death rate increases. c. The birthrate becomes lower than the death rate. d. The birthrate and the death rate remain the same.
No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
the plant is sexually reproduced ok
Birthrate must exceed death rate
natural selection or genetic drift
Mutation cannot occur. Apex
Without variation there is nothing to select from.
there must be atom and molecule movement for heat and a suitable environment for heat to grow, such as, it should already be hot where the heat is occurring
