In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?

The peas with the purple flowers were dominant and the peas with the white flowers were recessive.  

Explanation:

In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers.  The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant.  The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple.  The flowers were only white if both alleles were for white flowers.  

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.
