The Serratus anterior in man is homologous to the Serratus ventralis  muscle in the cat. The Serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and insects along the entire anterior length of the medial border of the scapula. The Serratus anterior acts to pull the scapula forward around the thorax. Serratus ventralis in the cats looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs.

Answer; 
-Because of Homeostatic imbalance as we age our body organs become less efficient, and our internal conditions become less and less stable. This event has a risk for illness and produce changes we associate with aging.
Explanation; 
-Homeostasis is the body's ability to maintain a relatively stable internal environment even though the outside world is constantly changing. It involves both positive feedback Loops and the negative Feedback loops. 
-Aging is a general example of disease as a result of homeostatic imbalance. As an organism ages, weakening of feedback loops gradually results in an unstable internal environment. This lack of homeostasis increases the risk for illness and is responsible for the physical changes associated with aging.

The correct answer is:
S phase
Explanation:
S phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Accurate and accurate DNA replication is needed to counter genetic exceptions which often lead to cell death or disease. DNA replication occurs during this S (synthesis) phase. Gap 2 (G2): During the gap between DNA structure and mitosis, the cell will remain to grow and design new proteins.
