Answer:
D)It will lead to forced migration.
Explanation:
Forced migration is an involuntary, sudden movement of organisms from one geographical location to another. This is often in response to short term environmental changes such as drought, famine, etc
When an ecosystem suddenly comes under stress due to these short term environmental changes, organisms may not be left with any other choice but to move or go to new locations in the quest for survival. The organisms may not have left the ecosystem in the absence of such short term ecological stress. This is what is meant by forced migration.
Answer : 0.026 moles of oxygen are in the lung
Explanation :
We can solve the given question using ideal gas law.
The equation is given below.
We have been given P = 21.1 kPa
Let us convert pressure from kPa to atm unit.
The conversion factor used here is 1 atm = 101.3 kPa.
V = 3.0 L
T = 295 K
R = 0.0821 L-atm/mol K
Let us rearrange the equation to solve for n.
0.026 moles of oxygen are in the lung
Answer:
82500000000000000000000000
Explanation:
This is the only answer I can come up with.
An ionic bond is a bond which occurs when there is a
difference in the electronegativity of the atoms. One atom which has a stronger
electronegativity tends to steal the electron of the other less electronegative
atom hence making it more negative (anion), while the other becomes a cation.
So answer is:
