Answer:
<em>Bracketed and indented keys are two dichotomous/or branching keys with an ordered, numbered couplet, and spatially differentiated respectively.</em>
Explanation:
Dichotomous keys are used in the identification and classification of taxa.
Bracketed keys, or parallel keys, are easy to understand- for efficiency, these keep the first two entries of every couplet or pair being compared. It also makes use of a numbering system in the couplet choices for easy tracking.
Indented keys maintain an equal distance from the margin on the left of the pages. Successive couplets are indented til the taxon is identified.
Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms.
<h3>Mendel's Experiments</h3>
Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.
From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.
Mendel noted traits can be divided into dominant and recessive phenotypic characteristics.
Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.

A compound (for example: H2O)
Answer:
upper gastrointestinal scan
Explanation:
Upper gastrointestinal series is the radiographic examination of upper gastrointestinal tract. Esophagus, stomach and then duodenum are visible on the X-ray film by the use of the liquid suspension which may be barium or water-soluble contrast.
Fluoroscopy is used during upper GI series. A continuous beam of X-ray rays is passed through body part and is transmitted to the monitor so that body part and the motion of it can be seen in every detail. <u>In upper GI series, the fluoroscopy allows radiologist to see movement of barium through esophagus, stomach, and duodenum as the person drinks.</u>
