Facilitated diffusion is usually significant to pass the ions across the hydrophobic layer of the plasma membrane. Transmembrane integral protein and careers proteins provide the channels that allow the ion to pass across the membrane. When an ion bind to their active site on the protein (note that the proteins are very selective), the protein changes conformation. It is this change in conformation opens up the channel that allows the ions to be passed across the membrane. When the ions are released inside of the cell, the protein resumes normal shape (and the channel also closes) and the active site becomes available again or another ion.
Answer:1)Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance
2)Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids.
3.)Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.
Explanation.
Basically the longer the chains of fatty acids the higher the degree of energy produced as heat energy, and therefore the higher the insulation.
Unsaturated fats clogged together and the aggregate carbons and hydrogens ensured insulation.

Answer:
Genetic Engineering is on purpose.
Explanation:
Genetic engineering could range from selective breeding to adding/removing DNA and RNA. Natural reproduction occurs with the sole purpose of creating successful offspring. The offspring could he tainted if the male and female are related leaving it to not have the DNA or RNA necessary to lessen the likelihood of dysfunctional genetics.
Do you know what a pangea is well Pangea is another supercontinent the reason why we're not Pangea is because something dead which oceans with lava cools off it cools off from old to new the new rocks are pushing the consonants together and eventually and a couple of million years it will be Pangaea again
