Inhoud

Aktiwiteit: om diere volgens kenmerke te klassifisseer [lu 2.2]

Diere met ‘n ruggraat of werwelkolom en ‘n inwendige geraamte (endoskelet) word in een groep geplaas en diere sonder ‘n ruggraat of werwelkolom word in ‘n ander groep geplaas. Die groep met ‘n werwelkolom word gewerwelde diere of Vertebrata genoem. Die groep sonder ‘n werwelkolom of ruggraat word die ongewerwelde diere of Invertebrata genoem. Sommige van die Invertebrata se liggame word deur ‘n harde dop buite-om beskerm, bv. die krap of die sprinkaan. Hierdie harde dop word die uitwendige geraamte of ‘n eksoskelet genoem.

Die onderstaande diagram toon aan hoe diere volgens bepaalde kenmerke ingedeel word:

‘n Interessante vraag: Swamme is nie as deel van die plante of diere aangetoon nie. Probeer uitvind waar hulle hoort.

Opdrag 4:

Bestudeer die volgende sketse en groepeer die diere na aanleiding van die voorafgaande diagram.

(i) Kriteria vir sortering van Vertebrate

Werweldiere kan na aanleiding van hul tipe liggaamsbedekking gesorteer word.

Opdrag 5:

Raadpleeg weer die diagram en stel die onderskeie werweldiere met hul spesifieke liggaamsbedekking diagrammaties voor. Wees kreatief en gebruik illustrasies, asook woorde.

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
