Question

Question 1 2 pts Which statement represents a result of natural selection! o the best adapted individuals have lower ness ele frequency in a population does not change Onewalls are added to the population seeded O different phenotypes with a species we favored in different habitats Question 2 2 pts When we say that one individual is more fit has higher fitness than other individuals, we mean that it produces more later than others in the population compete for food more successfully than others in the population O mates more frequently than others in the population Ispically stronger than others in the population D Question 3 2 pts Humans share several features with salamanders. Certain genes and proteins are nearly identical between the two species, both species have four limbs with a similar skeletal structure, the species early embryos are very similar and where the salamander has a functional tail.humans have a vestigla tailbone. In evolutionary terms, these similarities are examples of O adaptation by all selection O homologies

Answer 1

1. New alleles are added to the population as needed.
Alleles help organisms survive and reproduce better than their peers, natural selection helps in increasing the frequency of alleles from one generation to another if needed.

2. Mates more frequently than others in the population.
In the process of evolution, the fitness is considered as how well the organisms survive and reproduce. Fitness of an individual depends on how more often it passes its genes by mating more frequently than others.

3. Analogies
Analogy means the comparision of two things in significant respects. salamanders and humans are from two different species yet they can be comapared in some significant aspects.
