Living organisms make and use three main types of ribonucleic acids (RNA) for their biological functions: ribosomal RNA (rRNA) messenger RNA (mRNA) transfer RNA (tRNA)

Part A

Drag these words to the space

(1) tRNA: "contains an anticodon" "has amino acids covalently attached in active form"

(2) mRNA: "has introns and exons" "contains genes for a protein"

(3) rRNA: "is found in ribosomes" "is the most abundant form of RNA"

Part B

(1) Replication: Leave blank because no RNA is involved .

(2) Transcription/RNA processing: mRNA because it is synthesized from the information in DNA

(3) Translation: rRNA and tRNA

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

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.
