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 :)

I. Facilitated diffusion is your answer.
Active transport <span>is the movement of molecules across a cell membrane into a region of higher concentration, this process requires energy. Both osmosis and diffusion are passive transportations which means that they don't require energy.
Hope this helps!

It is because it may happen more often than others and can do more damage quicker.
Answer:
All four complexes pump protons out of the mitochondrial matrix
Explanation:
What differs are the biochemical processed by which each complex pumps out the protons. Only ATP synthase pumps proton from the intermembrane space to the matrix. This is as it harnesses the proton motive force, created by the other complexes, to generate ATP molecules.
