The answer is C.) Sac. More formally known as the amniotic sac. It's also sometimes called the bag of waters.
The relative humidity<span> drops to 25% only. If you heat air with water in it, the absolute </span>humidity<span> will stay the</span>same<span>, but the (much more common) relative </span>humidity<span>will go down: the </span>same<span> amount of </span>humidity<span> at higher</span>temperature<span> will be a smaller percentage of what the air could handle at the higher </span>temperature<span>.</span>
The result would be an increased atmospheric concentration, which alters the distribution or abundance of species. Leached phosphorus can then lead to algal blooms and that clogs the aquatic ecosystem.
