Answer:
5.6L
Explanation:
Given parameters:
number of moles = 0.25mol
pressure on gas = 1atm
temperature = 273K
Gas constant R = 0.0821Latm/molK
Unknown:
Volume of gas = ?
Solution:
Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.
It is mathematically expressed as;
PV = nRT
where P is the pressure
V is the volume
R is the gas constant
T is the temperature
n is the number of moles
All the parameters are in the appropriate units and we simply solve for the volume of the gas;
1 x V = 0.25 x 0.0821 x 273
V = 5.6L
Exocytosis is basically when your vesicles transport materials out of a cell.
Once the neurotransmitters are synthesised and packaged into vesicles, they are transported until the vesicles reach the cell membrane. Then the 2 bilayers rearrange themselves so that the vesicles are able to fuse with the membrane . Once that occurs, the neurotransmitters will spill out whatever it was carrying.
Two examples of exocytosis are
1) your nerve cells releasing transmitters (explained in the description above)
2)your T cells sending vesicles filled with enzymes to viral infected cells
The mutation must occur in the egg cell
Answer:
Deforestation increases the build-up of greenhouse gases because the removed trees would have consumed carbon dioxide.
Explanation:
Answer:
The answers are matched as follows:
African forests have been hunted to near extinction levels to obtain ivory-------------->human exploitation
The eruption of mount Saint Helens destroyed some populations of conifers------> natural disasters
An infection with a fungus reduced the population of North American Elm trees ----> disease
Increasing global temperatures have altered migration patterns of humpback whales ------>climate change
