Agapanthus is a dominant, homozygous lethal trait among telorites from the planet teleflora. subjects with this condition love to send flowers. from a group of telorites heterozygous at the agapanthus locus (with two alleles: a = dominant (trait) allele, a = recessive (wild-type) allele), 88% of the telorites have the agapanthus phenotype, and 12% look wild-type.
also, true-breeding wild-type telorites (aa genotype) have 10% penetrance. a telorite with the agapanthus phenotype mates with a true-breeding telorite with the wild-type phenotype. one of the f1 children is randomly selected and is mated back to the true-breeding wild-type parent. out of twenty f2 individuals, we only observe nineteen wild-type phenotype and one agapanthus phenotype.
the genotype of the randomly-selected f1 subject must be:
a. aab. aa. c. we cannot say with certainty. we need to perform a chi-square goodness of fit test. d. aa. e. aa or aa.

i am going to guess that it is co2.

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.  

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
