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.
What else can I help you with?
What must occur for a population to grow?
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.
What must happen for specification to occur?
A population must be isolated in some way
What must be true for hardy equilibrium to occur?
mating must happen randomly
What must occur for a gene pool within a population to change?
A genetic mutation within the population.
What must occur in a population for it to grow?
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.
What must be true for equilibrium to occur?
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
Which condition is necessary for a population to grow?
Birthrate must exceed death rate
What steps must occur for a seed to grow into new plant?
the plant is sexually reproduced ok
What must occur for the gene pool within population to change?
natural selection or genetic drift
Which of these is one of the conditions for hardy-weinberg equilibrium?
Mutation cannot occur. Apex
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
What are the four things that must happen for natural selection to occur?
For natural selection to occur, there must be genetic variation present in a population, some of which is heritable. This variation must lead to differences in survival and reproduction (differential fitness). Individuals with advantageous traits must pass those traits on to their offspring. Over time, these advantageous traits become more common in the population.
