What dose denature mean and how dose it relate to enzyme function

Definition of Denature: to treat the by chemical or physical mean so as to alter its original state. Basically it means to change something from its original state(like at first an ice cream was cold, but the sun melted it and the ice cream became warm).

Relationship of enzyme function: Proteins change their shape as the temperature changes. Since the enzyme's activity is based on the shape, temperature change may mess up its process and then the enzyme will not work. High temperature will cause the enzyme to denature and the enzyme's structure will start to break up.

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.
