one is relative to whats happening now and the other is what happened in the past hope this helped!
Answer:
D. physiological mechanisms are the basis of behaviors.
Explanation:
The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment.
This way of communicating is called electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.
Answer:
A The cells genetic material is copied
Explanation:
Cell division is the process by which a single cell divides into two daughter cells. Each daughter cell needs to inherit an entire copy of the genetic material, therefore, before cell division occurs, the DNA is replicated. This allows the cell to divide the genetic material between two daughter cells, such that each cell inherits the complete genome.
Answer:
When they slide down, they lose this potential energy, which turns into kinetic energy and thermal energy. Thermal Energy - This energy is related to the temperature of a body or a system. When friction is involved in a system, part of the kinetic energy is transformed into thermal energy.
