answer of given question is trueeeeeeeee
Answer:
<em>Binary fission is the most common form of reproduction in prokaryotes such as bacteria.</em>
Explanation:
The process of binary fission can be described as a kind of asexual reproduction. Asexual reproduction is the method of reproduction in which a parent cell produces two new daughter cells which are identical to one another and to the parent cell.
During binary fission, the parent cell divides into two by splitting. The DNA replicates itself and moves to opposite directions so that each cell receives one copy of the DNA. Finally, the cells split. This method of replication is common in prokaryotes such as bacteria.

Question: What is not one of the roles of the parasympathetic nervous system?
a) increases digestive functions
b) maintains resting heart rate
c) stimulating urination
d) controls the diameter of blood vessels
Answer:
d) controls the diameter of blood vessels
Explanation:
The activated parasympathetic nervous system is mainly associated with the rest and digest activities. This division of the autonomic nervous system triggers the digestive glands to release their secretions and stimulate the contractions of smooth muscles of the digestive tract to upregulate the processes of digestion and absorption of nutrients. In this way, the parasympathetic nervous system restores and conserves the energy of the body. It has no effect on the diameter of blood vessels.
The sympathetic nervous system triggers constriction of blood vessels that supply blood to kidneys and digestive tract during emergency conditions. It also dilates the blood vessels that supply blood to skeletal muscles, cardiac muscles and liver to facilitate increased blood supply to these tissues.

Both positive and negative reinforcement are the parts of conditioning. In positive reinforcement the subject is awarded for the particular sets of desired behavior but it is opposite for the negative reinforcement the subject is punished for undesired behavior.
In positive reinforcement favorable stimulus is chosen by the subject which made the subject to avail the reward whereas in the negative reinforcement , the aversive stimulus is intended to reduce the undesired behavior by punishment.
