The male and female flowers spring from the axils of the leaves on separate plants. The flowers of the male plant grow in panicles, 3 to 5 inches long, but are not cultivated. Only the female flowers are used for medicinal purposes. The fruit of the female plant are called strobiles and resemble small pine cones.
The atmosphere is composed of a mix of several different gases in differing amounts. The permanent gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%.omposition of the Atmosphere extended definition. The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. The most abundant gas in the atmosphere is nitrogen, with oxygen second.
Currently voted the best answer. Yes it is. Air is mainly composed of nitrogen, oxygen, and argon, which together constitute the major gases of the atmosphere. The remaining gases are often referred to as trace gases, among which are the greenhouse gases such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Our atmosphere contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.
