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.
2) Antigens which helps to stimulate the immune response.
3) Proteins of the plasma membrane.

Answer:
Explanation:
A saprophyte derives its nutrients and energy form the organic matter of dead organism, wheras a parasite lives in or on another living organism and derives its nutrients and energy from that living organism.
Saprophytes derives their nutrition by feeding on dead and decaying organisms. Most saprophytes are fungus. The energy needed for performing their life functions are sourced from dead organisms. All saprophytes are therefore heterotrophs and consumers in the food chain.
Parasites are organisms that derives their nutrition from their host. They completely depend on their host to provide nourishment for them. Most parasites on the long run harms their host. An example is tapeworm and pig.
Answer:
pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
Calculating pressure
To calculate pressure, you need to know two things:
Pressure is calculated using this equation:
pressure = force ÷ area.
