Which of the following statements is false? question 14 options: a. mutations do not occur in hox genes. b. hox genes that are found in different animals are very different from each other. c. hox genes control the normal development of an animal. d. hox genes occur in clusters.

The answer is; A

Hox genes in species are highly conserved. This, however, does not mean that mutations do not occur in hox genes.  Rather, this is due to the disadvantage of mutation in this region. An individual with a mutation in the Hox gene is less likely to survive even past birth because of the significance of this gene to the development of the body.  

i think the answer is b.

hope it

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.
