Bladder is an internal organ, which is mainly made up of smooth muscles. The contractions of the smooth muscles are not under voluntary control. The contraction of these muscles are directed by brain, without any external control.
The autonomic nervous system is a part of nervous system, which is responsible for regulation of the all the conditions, which occur involuntarily. It directs the movements of all smooth muscles.
Hence, the movements of the bladder are controlled by the autonomic nervous system.
Answer:
somatic nervous system
Explanation:
The motor division of the peripheral nervous system includes a somatic nervous system and an autonomic nervous system. The somatic nervous system (SNS) delivers motor information from the central nervous system to skeletal muscles only. Therefore, the motor responses of the somatic nervous system are consciously controlled by humans. This makes it control the voluntary actions of the body. The somatic nervous system includes the somatic motor neurons that connect the skeletal muscles with the central nervous system.
Answer:
D
Explanation:
D the red and white alleles are expressed independently of each other. You know this because roan is when both red and white are present. So therefore, because of this, the cow can be red, white, or both depending on what alleles are present.
The answer is operon. These set of genes are transcribed together because they share a single promoter and operator. Therefore they are transcribed into one mRNA and translated together. These genes are, therefore, expressed together at all times. Examples are the tryptophan and lac operons of Escherichia coli
