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
Answer:
1. Merocrine
2. Holocrine
Explanation:
Merocrine glands are the exocrine glands that synthesize their secretions on ribosomes attached to rough ER. These secretions are packaged by the Golgi complex into the secretory vesicles and are released from the cell via exocytosis. Tear glands, salivary glands are some examples of merocrine glands.
The cells of holocrine glands do not have vesicles but accumulate a secretory product in their cytosol. The mature secretory cells rupture to release the secretory product. This results in the presence of large amounts of lipids from the plasma membrane and intracellular membranes in secretions of these glands. One example of a holocrine gland is an oil-producing gland of the skin.
C ribosomes is ur answer
mark me brainlist plz :)
