The lateral cord of the brachial plexus is lateral to the axillary artery and is formed from the anterior divisions of the superior and middle trunks; thus, it contains portions of nerves
.
The three anterior and three posterior divisions of the brachial plexus combine to generate the cords in the following manner: The anterior division of the superior trunk and the anterior division of the middle trunk combine to generate the lateral cord.
The lateral pectoral nerve, which originates from the lateral cord and contains the spinal levels
and innervates the pectoralis major muscle, is the only nonterminal branch. The medial pectoral, medial brachial cutaneous, and medial antebrachial cutaneous nerves are the three non-terminal branches that emerge from the medial cord.

Answer:
The graph illustrating such a phenomenon will show a sharp curve in upward manners in the beginning but then will grow downwards as the predation increases.
Explanation:
When a rabbit population is introduced in a habitat, the new habitat will have abundant food for the rabbits. As a result, the population of the rabbits will grow at a much faster rate and hence the graph will move sharply upwards in the beginning. But with the passage of time, the predators of the rabbits will also increase due to the abundance of their preys. More predators will feed on more rabbits and hence a slow decline in the curve will be seen afterwards.
Answer:
Golgi apparatus
Explanation:
The endomembrane system includes the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, several types of vacuoles, and the plasma membrane.
The Golgi apparatus consists of flattened membranous sacs called cisternae. They are stacked upon each other. The membrane of each cisterna in a stack maintains the unique internal space from the cytosol. Proteins and lipids formed on the ER are packed in many transport vesicles and are delivered to the Golgi apparatus.
The Golgi apparatus serves as a site for modification, and packaging of proteins and lipids. Modification of proteins in the Golgi apparatus results in the formation of several types of modified biomolecules such as glycoproteins. It serves as the site for the packaging of secreted proteins and sorting of other proteins to vacuoles and other organelles via transport vesicles. The transport vesicles carrying various biomolecules are formed in the trans face of the Golgi apparatus. These vesicles pinch off from the Golgi membrane and transport their contents to a specific destination.
A “polygene” or “multiple gene inheritance” is a member of a group on non-epistatic genes that interact additively to influence a phenotypic trait.
It's diffusion because it's movement from high to low concentration
