The cloning of Dolly the sheep ,a. demonstrated that differentiated cells contain only a fraction of their full genetic potential. b. demonstrated that the nuclei from differentiated mammalian cells can retain their full genetic potential. c. demonstrated, for the first time, that eggs are haploid and body cells are diploid. d. revealed that cloned mammals most resemble the egg donor.

Explanation:

Every cell of an organism contain equal number of chromosomes, like nerve cell, mammary gland cell, muscle cell, heart cell etc. all have same number of chromosome and equal amount of DNA. The morphology and functioning of different cell depends on the differential gene expression.

Cell express their genes according to the requirement or the environment or according to the signals.

The cloning of Dolly demonstrated that the nuclei from all the various  differentiated mammalian cells can retain their full genetic potential.

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.  

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
