ACTIVITY Could We Run out of Food?
Malthus thought we could. Do the following activity to better understand
Malthus's hypothesis. Get 2 empty egg cartons and a bag of rice. Label one
carton “Food supply" and the second carton "Population growth." In the food
supply carton, place one grain of rice in the first cup. Increase the amount by
one in each subsequent cup. Each grain represents a unit of food. In the
population growth carton, place one grain of rice in the first cup, and double the
number of grains of rice in each subsequent cup. This rice represents people.
1. How many “people" are there in the last cup?
2. How many units of food are there in the last cup?
3. What conclusion can you draw?

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

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.

sex cells are usually half's then they find another half and make a fertilize egg

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
