Answer:
Secretion of the neurotransmitter serotonin, which is a water-soluble amine molecule
Explanation:
Exocytosis is defined as the process where cell transports secretary products which are packaged in transport vesicles such as antibodies, peptide hormones, secretory proteins, and enzymes with the help of cytoplasm to the plasma membrane.
Some example of exocytosis are:
1) Neurotransmitters secrets from nerve cells.

Answer:
c) 330
Explanation:
Formula to calculate exponential growth is written as:
y = a( 1+r)ⁿ
a = initial quantity
r = growth rate as a decimal
n = number of time intervals
y = quantity after n time
As per the question given
a = 300
r = 0.1
n = 1 year
y = ?
Thus,
y = a( 1+r)ⁿ
300(1+0.1)¹
300 × 1.1 = 330
Therefore,
y = 330
