Answer:
E. will have the same genes at the same locations
Explanation:
Homologous chromosomes are the pairs of chromosomes. The members of a homologous pair are genetically and morphologically similar to each other. One chromosome of a homologous pair is inherited from the father while the other one comes from the mother.
Genes have two or more alleles. The alleles of a gene occupy the corresponding position on the homologous chromosomes. These specific positions of alleles of a gene are called loci. Therefore, a particular locus is occupied by alleles of the same gene on two homologous chromosomes.
This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.
Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.
Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.
These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).

Answer:
Evolutionary biology illustrates both the pattern and processes. The processes of evolution are natural selection and other mechanisms, which modifies the genetic structure of the populations. These processes result in evolutionary patterns, that is, the products generated by evolution with time.
Phylogeny refers to the evolutionary history of a species or a group of species. In order to redevelop phylogeny, the scientists use systematics, that is, an analytical method to categorize the diversity and finding the evolutionary associations between the extinct and the living species.
The evidence used to redevelop phylogenies can be attained from the fossil record and from the biochemical, morphological, and genetic similarities between the species. The scientists are functioning to develop a universal tree of all life, which will get refined with the gathering of new information.
