Which of the following cells would have a different genetic composition than the other three in an animal with a diplontic life cycle? a. neuron b. bone c. cell kidney d. cell gamete

D (Cell gamete)

Explanation:

A gamete is a sex cell while the other three cells in the options are somatic or body cells. The bone, kidney and nerve cells are regular types of body cells that do not perform any reproductive function. Hence, they contain two set of chromosomes (diploid) since they replicate through mitosis, which is a kind of cell division that gives rise to daughter cells with identical genetical composition. The animal has a diplontic life cycle, meaning that it is a diploid organism, hence it undergoes mitosis in its somatic cells to produce diploid somatic cells, which has the same genetic composition as the parent cell.

On the other hand, gametes are sex cells that arise from the meiotic division of reproductive cells. Meiosis, in contrary to mitosis, is a type of cell division that produces daughter cells with a reduced number of genetic material (chromosomes). The reproductive cells of a diploid (2n) animal undergoes meiosis to produce haploid (n) gametes (sperm in male, egg in female). These gametes contain half the number of chromosomes as the parent cell, making them genetically different from the parent cell.

These haploid gametes (sperm and egg) fuse together to result into a diploid organism.

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.
