<span>It began with selective breeding in the ancient times where a population with desirable traits were bred with other population to achieve a desired set of traits. It then continued with the advance in the discovery of bacteria (Escherichia coli) and antibiotics. Then Watson and Crick discovered the structure of DNA. The latest advance being that of gene sequencing and gene editing tools. </span>
5 chromosomes. Meiosis results in 4 haploid cells, meaning they have "n" pairs of chromosomes. The diploid cell that the 10 chromosomes originated in has "2n" pairs. This leaves us with a simple equation to solve the problem, 2n=10, so n must equal 5 chromosomes.
Firstly light is an external stimuli. in plants - shoots are positively phototrophic while roots are negatively phototrophic.
One of the few advantages is In sexual reproduction, more variations are produced. So in turn this ensures survival of species in a population.
Cellular respiration (cells covert nutrients into atp)
