I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

THE TWO MOST COMMON REASON FOR MODIFYING THE LAND IN SOUTH AND SOUTH ASIA IS
(i) first is significantly, the area of lands categorized as under forest/woodland and wetlands declined .At the same time, cultivated area increased .
(ii) another is requirement of additional land due to increase in population.
Explanation:
Between 1880 and 1980, the South and Southeast Asian landscape underwent dramatic modification.The 81% of the lost forest and wetland vegetation appears to have been converted into expanded agricultural land.
Human population in this region more than tripled between 1880 and 1980, producing an enormous demand for additional land for cultivation.
Inputs: carbon dioxide, water, and light
Outputs: glucose and oxygen
The correct answers are:
B. Warmer air promotes more evaporation.
D. Humidity refers to the amount of water vapor in the air.
E. Areas with a lot of surface water have higher humidity than drier areas.
The humidity can simply be described as the amount of water vapor in the air. The humidity can vary, and it can be very high in certain place for the whole year, very low at other places for the whole year, or to be changing seasonally.
The areas that have a lot of surface water (the Amazon River Basin) tend to have higher humidity than the places that lack surface water (Sahara Desert). Also, the humidity depends a lot on the temperature of the air. The warmer the air is, the higher the humidity, and vice versa, the colder the air is, the lower the humidity.
