Use more words so your question makes sense.
When a population reaches carrying capacity. Apex 9.5.2 (CST) bio test
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
What is the third step in natural selection?
There are really no steps in natural selection - just conditions required for it to occur.
How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.

what causes natural selection to occur?
the presence of predators
Why would natural selection not occur in this population?
Natural selection may not occur in a population if there is no variation in traits among individuals, if all traits are selectively neutral, or if the environment is stable and consistently favors all individuals equally. Additionally, if all individuals are equally successful in reproducing and passing on their genes, natural selection may not be operating in that population.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What term is defined as natural change that occur in communities over time?
Natural selection
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
Why does evolution evolution by natural selection can not occur if the variation in a characteristic does not contribute to differences in fitness?
For evolution by natural selection to occur, differences in fitness among individuals must arise due to variations in a characteristic. If the variation in a characteristic does not affect an organism's ability to survive and reproduce (i.e., fitness), there will be no selection pressure acting on that characteristic, and thus no evolution by natural selection will occur.
