What is spacing in populations?
When a lot of individuals in a population are smoking weed.
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.
Do genera populations phyla kingdoms or individuals evolve?
Individuals evolve through natural selection, leading to changes in the characteristics of populations over time. These changes can eventually lead to the evolution of new species within a specific genus, which may contribute to the diversification of higher taxonomic groups such as phyla and kingdoms.
The smallest unit of evolution is the population?
Yes, populations evolve. Individuals/genes are selected.
How does population size affect the likelihood of changes in allele frequencies by chance alone?
Mutation rates are small but constant. With a typical mutation rate of 1 x 10-6, it is expected that 1 out of a million individuals in a population will carry the mutation. If the population size is small (10,000 or fewer individuals), the probability that the mutation will be present is small (~1% with 104 individuals). If population sizes are large (107 or more individuals), the probability that the mutation will be present is large (~10 mutants expected if 107 individuals are in the population). Mutations can be lost from populations through genetic drift, and large populations experience less genetic drift than small populations. Thus mutations are more likely to exist and persist in large populations than in small populations.
Does the population or organism go through natural selection?
No, populations of organisms evolve, individuals are naturally selected.
When does Predation occurs with in individuals?
Predation occurs when individuals in one species-population each kill multiple individuals in one or more other species-populations to use them as a resource.
Can populations evolve?
Evolution is the change in allele frequency over time in a population of organisms.Short answer, populations are the only thing that evolves. Individuals die. Traits are passed on to progeny that make up the variations in the populations that evolve.
Why is variation beneficial to a population that is undergoing change?
Yes, it is. If there is variation in a populations, and a sudden catastrophic event occurs, there is more of a chance that some of the individuals in the population will survive, and the population will not die out.
When individuals in a population reproduce at a constant rate it is called?
When individuals in a population reproduce at a constant rate, it is called an exponential growth. Populations generally experience this growth under ideal conditions.
What is the population of Hindustan Antibiotics Limited?
Hindustan Antibiotics Limited's population is 1,500.
Why wouldn't insecticide kill all the insects in a population?
Because of natural variation in a populations, some individuals may have an innate tolerance to the insecticide.
