What is the difference between bracketed key and indented key?​
____ [38]

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.

Explain how dysfunction at one level of organization impacts other levels and provide an example.
Nuetrik [128]

Answer:

Please find the explanation below

Explanation:

All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.

Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).
