In a population that is in Hardy-Weinberg equilibrium, the frequency of the dominant allele (in this case, for orange flowers) is p and the frequency of the recessive allele (for yellow flowers) is q. 48% of the population is heterozygous for the flower color alleles in this plant species under Hardy-Weinberg equilibrium. In this particular flowering plant species, orange flower color shows simple dominance over yellow flower color.
Given that 16% of the population show yellow-flower phenotypes in a population that is in Hardy-Weinberg equilibrium, we can calculate the percent of the population that is heterozygous for the flower color alleles.
Step 1: Determine the frequency of the recessive allele (q)
Since 16% of the population has yellow flowers (recessive phenotype), the frequency of the recessive homozygous genotype (qq) is 0.16. To find the frequency of the recessive allele (q), we take the square root of 0.16, which is 0.4.
Step 2: Determine the frequency of the dominant allele (p)
Using the Hardy-Weinberg equilibrium equation, p + q = 1, we can calculate the frequency of the dominant allele (p). Since q = 0.4, then p = 1 - 0.4 = 0.6.
Step 3: Calculate the percentage of heterozygous individuals (2pq)
To find the frequency of the heterozygous genotype (2pq), we multiply 2 by the frequency of p and q: 2 x 0.6 x 0.4 = 0.48.
Therefore, 48% of the population is heterozygous for the flower color alleles in this plant species under Hardy-Weinberg equilibrium.

Answer: To mutate is to change, especially genetically. When plants mutate, their genes change in a way that makes them look, grow, or reproduce differently. The word mutate comes up most often in biology, to describe the natural — or artificial — process of genetic change.
Explanation:
Answer and Explanation
Mutate means “to change into something else.” When a mutation occurs in a gene, it changes the way a gene expresses in an organism. Proteins are the products of gene expression. Therefore, a mutation in a gene may cause a change in the way proteins form.
The Galapagos islands contain a range of habitats.
b.
The Galapagos islands originate from volcanoes.
c.
The birds Darwin found in the Galapagos were different types of finches, not separate types of birds.
d.
Many of the organisms in the Galapagos lived in hostile environments.
The correct answer form all of the given options is (c) The birds Darwin found in the Galapagos were different types of finches, not separate types of birds.
Further explanation:
Adaptation theory given by Charles Darwin is also called survival of the fittest theory or just survival theory, it explains the ability of the organism to adapt to the changes of the environment over generations and give rise to new form of species.
Darwin named this theory natural selection stated that;
There is internal adaptation as well which cannot be seen from outside the body for example vertebrates adapting to regulate their body temperature.

The bones in the front limbs of many mammals are similar in their structure and arrangement because they have common ancestors. The term used to describe the physical similarities between related species is Homologous organs. A very common example of homologous structure in mammals are forelimbs of human, whale and dogs. These structure perform different function such that the forearm of human is used for holding things, flippers of whale are used for swimming and forearm of dog is used for walking and running.
