The rights and the privileges of freedmen were still threatened after the civil war because laws were still made to regulate their activities. The black codes law were enacted which controlled the way a freed man can live; strict restrictions were placed on them, they can not vote, serve on jury, travel freely or engage in occupation of their choice.
Hope this helps.
Answer: toeboard
Explanation: The Occupational Safety and Health Administration defines the Walking-Working surfaces regulation for the secure construction of stairs in industrial environments. For platforms or walls that are 4 feet or higher above the ground and do not have surrounding walls, it is mandatory to build a standard railing around them. In cases where there is a moving machinery, people can pass or there is an equipment which would be harmful when falling objects come in contact with it, the railings must have a toeboard.
A toeboard is an equipment fixed vertically to prevent items from falling for the platform.
<span>Unlike a lytic infection, a lysogenic infection
requires a virus to insert its nucleic acid into a host cell’s DNA. The answer
is letter A. Once it is inserted, the normal DNA replicates along with the host
DNA. The normal DNA will become inactive and thus permitting the host DNA to
continue it normal process.</span>
According to the statement, a cell line known as heal cells has been employed in cell research for over 70 years. These cells were extracted from either a patient suffering from cervical cancer since they are not normal and it might theoretically live forever.
<h3>Briefing:</h3>
HeLa cells are malignant cells rather than normal cells. In normal cells, chromosomes have telomeres at their ends, which shrink after each cell division. The cell enters senescence when its telomeres reach a certain length. Telomere shortening is hence the cause of cellular senescence.
Telomerase is continuously produced and expressed in HeLa cells. Telomerase is an enzyme that prevents telomere shortening and therefore also cellular aging.
<h3>Can cervical cancer be cured?</h3>
Cervical cancer is treatable, but it is impossible for doctors to guarantee that it will not recur after therapy. As a result, doctors frequently use the term "remission" to characterize cancer that has disappeared and has stopped longer causing symptoms.
<h3>Where else does cervical cancer begin to spread?</h3>
Cancer can spread in these places. Cervical cancer most commonly spreads toward the lymph nodes, liver, lungs, and bones.
