The correct answer is option A, S Phase - DNA Replication
The DNA replication begin at the S phase of the cell cycle. In this phase, the cell grows and prepare itself for the DNA replication while the other components such as centro some undergo replication. The S phase occurs during the inter phase and the genetic material duplicates itself before entering the mitosis and meiosis cell division in the next stage.
heredity is when a certain trait is passed down from human to there children or how animals have offspring and raise them. it works the same for any speciesis including humans. for example if your mother has blue eyes and your father brown you may get one of theirs or you may get a mix of their colors and you may even get your grandparents eye colors. same with mice it may be two brown mice and most likely they would produce brown offspring
another example for humans is my parents both hve dark hair but my dad had blone hair when he was younger and so did his mom so i ended up getting a mix of blonde hair with brown! hope this helps!!

Answer:
The correct answer is option c. the sympathetic and parasympathetic nervous systems.
Explanation:
The parasympathetic nervous system is the one that controls involuntary functions and acts. It also causes or maintains a body state of rest or relaxation after an effort or to perform important functions such as digestion.
The sympathetic nervous system is the one that controls visceral reactions and reflexes, that is, it controls how our body responds to a threatening situation, as is the case in the example.
Both systems make up the autonomic nervous system which is in charge of controlling the involuntary functions of our body.
