Carbon 14 has a half life of 5,730 years. Scientists measure how much carbon 14 the rock has. For objects older than 50,000 years, scientists will test the age of the things surrounding it.
As far as I can tell it would be D. I took 5 million and multiplied it by 8 to get that.
Answer:
Option-B
Explanation:
DNase I is an enzyme which acts on the DNA in its single-stranded, double-stranded and chromatin form.
The DNase acting sites on the DNA is known as the DNA I hypersensitive site. The DNase I hypersensitive site allows the DNase I to act as the condensed form becomes less condensed. This mechanism can be associated with the transcription as, during transcription, the DNA becomes less condensed and is open to DNase I enzyme.
Thus, Option-B is correct.
PAMPs and DAMPs bind to pattern-recognition receptors or PRRs associated with body cells to induce innate immunity.
As the primary bronchi enter the lungs, they branch off into smaller secondary bronchi that carry air to each lobe of the lung. Thus, the right bronchus branches off into 3 secondary bronchi while the left lung branches off into 2 secondary bronchi. The secondary bronchi further branch into many smaller tertiary bronchi within each lobe. The secondary and tertiary bronchi improve the efficiency of the lungs by distributing air evenly within each lobe of the lungs.
