Answer:
The statement that says " The mitochondrion contains a circular chromosome that has bacterial DNA sequences" is true among the all statement given above.
Explanation:
The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:
- Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.
- Ability of these organelles to divide only through binary fission as the bacterial population.
- The associated ribosomes are similar to the bacterial ribosomes.
- Presence of porins in these organelles similar the bacterial membrane.

Answer: B. Epididymis
Explanation:
The region that'll be affected by the smooth muscle stimulant to help food move forward by peristalsis and hence leads to increased urination include the ductus deferens, urinary bladder and the urethra.
It should be noted that the epididymis isn't affected by the stimulant. The epididymis is simply the long, coiled tube which helps in the storage of sperm and then transports it from the testes.
The head of the epididymis is characterized by a thick epithelium which has a long stereocilia and a little smooth muscle. Therefore, the smooth muscle stimulant will not be necessary.
