What is DNA? Where is it found within a cell?

it is genetic material and its found in da nucleus

DNA is a double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins. It's found in the nucleus of the cell.

Explanation: Basically, if you look at DNA, you'll see that it has two strands which seem to twist (making it a helix, hence the term "helical"). If you uncoiled a strand of DNA, it would look like a ladder. The "rungs" of the ladder are called base pairs (adenine-thymine, guanine-cytosine) held together by a hydrogen bond. A goes to T, and G goes to C.

Let me know if you have any other questions!! I'm happy to help :)

the correct answer is d

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
