B, I think but I'm not positive. Hopes that helps...
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 :)

Answer:
D
Explanation:
One of the assumptions of the Hardy Weinberg equilibrium is that the population should not experience mutations. Mutations are usually the base on which natural selection acts by selecting the advantageous alleles and weeding out the disadvantageous ones. This is how populations evolve.
Other assumptions of this equilibrium are; there should be no migration (hence gene flow), the population is infinitely large, and mating is random.
That is the main difference between sexual<span> and </span>asexual reproduction<span>. </span>Sexual reproduction<span> just means combining genetic material from two parents. </span>Asexual reproduction<span> produces offspring genetically identical to the one parent.</span>
