The graph shows the maximum amount of water vapor that a sample of air can hold at different temperatures. This sample of air at 35°C and 60% relative humidity holds grams/cubic meter of water vapor. The same sample of air at 40°C can hold a maximum of 50 grams/cubic meter of water vapor. If the air currently holds 30 grams/cubic meter, then its relative humidity is %

are there any answer choices

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

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.
