I would first measure the temperature of the water then measure the temperature of the water AFTER the sun go down .
If you put a lump of solid carbon dioxide (dry ice) in a paper cup or
on a paper plate on the kitchen counter, it gets smaller and smaller
and finally it just disappears, but you never see a puddle around it
like you would with regular ice!
Carbon dioxide has no liquid phase when the pressure on it is less than
about 5 times normal atmospheric pressure. So in the kind of pressure
that we like to live in, dry ice goes straight to gas when it melts. That kind
of behavior is called "sublimation", and we say that the dry ice "sublimes".
Every substance has some pressure limit like that. For water, it's 0.006 of
normal atmospheric pressure. At any pressure lower than that, liquid water
can't exist, and an ice cube sublimes ... it melts directly into water vapor
without a puddle.
Your image isn't clear so I couldn't see the proper option but lucky for you I have seen this question before so I will tell you the answer.
The answer is option D (facilitated diffusion).
Answer:
True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.
Explanation:
- An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
- Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
- Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.
