Yes, Chemical reactions occur slower at lower temperatures and faster at higher temperatures. When you put a glow stick in cold water, the chemical reaction slows down but will last for a longer period of time. When you put a glow stick in hot water, the reaction speeds up but will be over quicker.
Not sure about the variable one though, sorry!
Living in herd is a structural adaptation.
There are three different kinds of adaptations: behavioural, physiological and structural.
Adaptations help animals survive and their ecosystem.
The second sentence does not sound correct but it seems correct to me (just not in grammar).
Hope it helped!
Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.
When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.
Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)
Since water flowed out of the cell, the cell lose water and shrinks.
Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.
So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.
The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.
Answer:
Beautiful Huntresses: Scientists Explain Why Mantises Evolved To Resemble Orchids : The Two-Way Typically, when insect females evolve to become larger than males, it's in order to produce more offspring. But female orchid mantises evolved to look like flowers for a sinister reason: to hunt prey.
<span>In simple terms, heavier plates get melted
in Mantle, become lighter in form of lava and create new plates. As we
have a re-cycle or the convection currents, there are cycles in
lithosphere.
There is continuous push and pull happening on and
below the Earth. When a plate is subducting on one end, there has to be
some reaction on the other end, right?
Ridge is developed on the
other side, where the same material which has been melted on the
subduction side helps to fill the gap at ridge side. Since the material
is just transfered from heavy to light, and reused in that cell, it is
called a cycle.
