Semi-conservative DNA replication means that one stand is new DNA and the other contains a newly synthesized strand.
Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
<span>The answer is dendrites. The protoplasmic projections of the neuron join other neurons dendrites enabling ann intricate network of neural networks, especially in the brain. The junction at which their join is called a synapse. Impulse travel from these dendrites to the body of the cell (soma) and through the axon</span>
