Answer AND Explanation:
Gnetophytes are gymnosperms
, they are woody and the embryo has two cotyledons
. Cycads are woody plants that produce seeds found in Subtropical and warm temperate regions and also they produce motile sperm cells.
Cellular structures and lifestyles
are much diversified.
In spite of these differences, the same basic molecular mechanisms govern the
lives of both prokaryotes and eukaryotes,<span> the general classes of
proteins involved in signal transduction are conserved all over living cell. This is manifested through the
re-used of protein receptors, protein kinases,<span> phosphoprotein phosphates, and ion channel receptors.</span></span>
Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (Beluga, Ossetra and Sevruga caviars). Depending on the country, caviar may also be used to describe the roe of other fish such as salmon, steelhead, trout, lumpfish, whitefish, carp, and other species of sturgeon.
Your answer should be lakes and forests. Acid precipitation will rot out forests because of the acid content and in lakes it raises the PH balance making it more acidic which in turn makes it harder for anything to live in these lakes or drink from them. (Hope this helps ^-^)
