Snails have a diploid chromosome number of 22. after meiosis, the snail’s sperm or egg would have 11 chromosomes. how many chromosomes would the zygote have after fertilization?

11
22
33
46

The correct answer would be 22.

A zygote or fertilized ovum is produced by fusion of sperm and egg nuclei.  

Thus, both sperm and egg contribute their genetic material in the formation of a zygote.

This fertilization event restores the chromosomal number to that of the parent cell.  

Thus, the zygote of a snail would contain 22 chromosomes, 11 of which are contributed by sperm and other 11 are contributed by the egg.

i think the answer is 95 hope this

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.
