The term "Central Dogma" was first proposed in 1958 by Francis Crick, discoverer of the structure of DNA, to describe the flow of genetic information. In 2-3 complete sentences describe how DNA (genetic information) influences phenotype (physical traits)

The description of the two-step processes, that is, the translation and transcription, by which the knowledge within the genes is passed onto the proteins is known as the central dogma. The information regarding the physical features of an organism, which is provided by the proteins is found within the DNA.  

A protein is encoded by a gene, which is a particular sequence of DNA nucleotides. All the physical traits, also known as phenotypes are determined by the genes, thus, it can be concluded that DNA influences phenotype.  

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
