Answer:
Both (b) and (c)
Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
Based on respiratory function tests, the correct options are:
- spirometer.
- vital capacity
- residual volume.
<h3>What is a respiratory function tests?</h3>
A respiratory function test is a test done to evaluate the ability of the lungs to take in air and remove carbon dioxide
The machine used for this test is called a spirometer.
Therefore;
- Ms. L's respiratory function was evaluate using a machine called a spirometer.
- The amount of air that can be expelled by maximum ex-halation after maximum inhalation is termed the vital capacity
- An increase in the amount of air remaining in her lungs after a normal expiration is called the residual volume.

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:
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence.
