Enzymes can be purified from the Golgi apparatus. The gene for the enzyme can be cloned and fused to the coding sequence of GFP to produce a GFP fusion protein. The GFP fusion protein can then be expressed in cell culture. Antibodies to GFP are readily available. To determine which region of the Golgi apparatus, cis, medial or trans, the protein is located in, the protein can be visualized by

the correct answer is:

a population changes in response to a change in the environment.

the answer is sex-linked recessive.

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.
