The mass spectrum is a visual graph that shows a Intensity vs Mass plot, like that shown in the picture. This is an actual mass spectrometer diagram for Rubidium. The mass of the isotopes of the Rb element is along the x-axis, while the y-axis is the relative abundance. The atomic mass is determined to be:

∑(Mass×Intensity) = 85(1-0.38) + 87(0.38) = 85.76 amu

Horatio found a plant growing on the ground along a stream. An image of the plant is shown. What kind of plant did Horatio find?
Korolek [52]

Answer:

nonvascular because it lacks stems

Explanation:

Non-vascular plants, or bryophytes, are almost the most primitive forms of land vegetation. They lack the vascular tissue system (xylem and phloem) needed for transporting water and nutrients. Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. They also lack true leaves, roots, and stems. Non-vascular plants are usually small, green mats of vegetation found in damp (wet) habitats. The lack of vascular tissue means that such plants must remain around moist environments.Just like other plants, non-vascular plants exhibit alternation of generations and cycle between sexual and asexual reproductive phases. The three main divisions of bryophytes are: Bryophyta (mosses), Hapatophyta (liverworts), and Anthocerotophyta (hornworts).
