The body is made to adapt; so it tries to adapt to its current environment. The breathing rate increases to help add more oxygen into the system, slowly boosting endurance as a survival mechanism from ages ago when we actually had to outrun predators. It was likely more efficient back then.
A body cavity is any fluid-filled space in a multi cellular organism other than those of vessels. Thoracic cavity is further separated into other cavities. Thoracic cavity is the chamber of the body of vertebrates that is protected by the thoracic wall. The thoracic cavity contains three major cavities or compartments that is the mediastinum and two pleural cavities. The correct answer is therefore, thoracic cavity.
Answer:
circular
Explanation:
Studies of conjugation in multiple Hfr strains revealed that the bacterial chromosome was <u>circular.</u>
<em>Conjugation in bacteria is a process through which genetic materials are directly transferred from one bacterium to another. The process was first discovered by the experimental work of Joshua Lederberg and Edward Tatum in 1946. The donor bacterium first makes a copy of the genetic material by replication and then pass a copy to the recipient bacterium. </em>
It was during the process of conjugation that scientists discovered that the genetic material of the bacteria is a circular chromosome, also known as the F plasmid. The <u>circular chromosome breaks at a particular point and becomes a linear structure before replication and then folds back thereafter</u>. The replicated chromosome is linearly transferred to the recipient cell.
