When males go through puberty they get broadening of the chest and the deepening of the voice.
The lipid bilayer is a membrane composed of two layers of phospholipids. A phospholipid is a molecule made up of a polar phosphate head and non-polar fatty acid chains.
- The diagram makes reference to the different components of the lipid bilayer.
- The main components of the lipid bilayer are phospholipids and cholesterol.
- The lipid bilayer is also composed of different proteins such as transmembrane integral proteins (channels) and peripheral proteins.
The structures observed in the diagram are as follow:
- Phospholipid molecule (A). Function: structural.
- Polar (hydrophilic) head of the phospholipid (B). Function: stabilize the membrane by its interaction with water.
- Integral glycoprotein (C). Function: signaling pathways and cellular communication
- Oligosaccharide attached to a peripheral protein (D). Function: form the glycocalyx.
- Cholesterol (E). Function: provide fluidity to the lipid bilayer.
- Integral protein (F). Function: signaling pathways and cellular communication.
- Phospholipid bilayer (H-I). Function: Semipermemable barrier that separates the intern cell medium from the surrounding environment.
- Transmembrane integral protein (protein channel) (G). Transport of materials.

Answer:
Specific epithet
Explanation:
The binomial nomenclature system combines two names into one to give all species unique scientific names. The first part of a scientific name is called the genus. The second part of a species name is the specific epithet.
Answer:
The correct answer is option E) "incubation and convalescence".
Explanation:
The incubation period of an infectious disease is defined as the lapse between when a person is infected and the first symptoms are onset. While the convalescence stage is defined as the gradual recovery that a person experience once she or he overcomes the infectious disease. In both, the first and the last stage of the infectious disease (incubation and convalescence, respectively) the patient does not experience signs or symptoms of the disease.
