D. It is type A because A is dominant and i is recessive.
Answer:
Direct observation of evolutionary change: creation of drug-resistant bacteria.
Fossil record: discovery of transitional forms of animals, discovery of shells of extinct organisms
Homology: similarities in mammalian forelimbs, identical genetic code in fireflies and tobacco plants, vestigial pelvis in right whales
Biogeography: resemblance of endangered island species to neighboring mainland species,
an agent, such as radiation or a chemical substance, which causes genetic mutation.
Answer:
Due to its function to fight against disease.
Explanation:
Improvement of strength in the human body is very important because strong body helps in fighting against diseases. Strong body helps in doing physical activities and also helps in protecting itself from every type of harm. Weak human body can't fight against diseases due to weak immune system so we can conclude that improvement in human body is necessary for survival, development and health of human.
Answer:
by phenotypically identifying plants unable (or with an altered ability) to synthesize auxins. This approach is called reverse genetics
Explanation:
Reverse genetics is a strategy widely used in molecular genetics aimed at analyzing the function of target genes by identifying defective phenotypes of one or more organisms following the disruption of the gene. In this case, a mutagenesis approach (i.e., irradiation with X-rays) was used to induce mutations in the gene/s involved in auxin production. Subsequently, the resulting mutant phenotypes, i.e., plants with an altered ability to synthesize auxin, can be used to reveal the biological function of individual (mutated) gene sequences.
