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:
Cytochrome c is an enzyme found in bacteria, fungi, plants and animals. Here it is given that the human amino acid sequence for cytochrome c differs at 12 locations from the sequence in horses and pigeons. This information might be useful for inferring in preliminary stages that horses and pigeons are closely related to each other since they both show similar amount of difference from humans.
However, this hypothesis is being made with respect to the the comparison between "humans and horses" and "humans and pigeons". To further test this hypothesis pigeons and horses should be directly compared to each other without the use of a third species like humans. Hence, the sequence for cytochrome c in horse and pigeon should be compared with each other rather than comparing to humans.
Symbiosis is the ecological relationship between two or more organisms living closely together with some form of feeding relationship involved. The three main symbiotic relationships are: - Mutualism, where both organisms benefit. - Commensalism, where one organism benefits while the other organism is not harmed. All of them thrive off of the other organism.
