In the 18th century, Carl Linnaeus published a system for classifying living things, which has been developed into the modern
Mazyrski [523]

Cavalier-Smith's model no longer separates prokaryotes and eukaryotes is the statement which differs from kingdom classification.

Explanation:

Cavalier-Smith in 1998 had reduced the kingdom numbers. The were brought down from 8 to 6. These are:

Animalia

Protozoa

fungi

plantae

chromista

bacteria

He divided eukaryotes into 6 kingdoms.  The kingdoms are refined for better classification.

While Carolus Linnaeus divided the organisms into two kingdoms

Animalia and plantae.

The five kingdom classification:

Monera (prpkaryotes)

Protista  ( unicellular eukaryotes)

fungi (multicellular decomposers)

plantae (multicellular producers)

Animalia (multicellular consumers)

It has drawbacks like in kingdom monera both autotrophs and heterotrophs  are included. Phylogeny is not explained in lower organisms of monera and protista. Virus is also in classification. Cavalier-Smith introduced a new kingdom called chromista which are single- celled or multicellular eukaryotic organisms as diatoms, algae, oomycetes and protozoans which perform photosynthesis.

Name the type of connective tissue that anchors the ribs onto the sternum.
Kazeer [188]

Hyaline cartilage makes up the costal cartilage that holds the ribs to the sternum. The most prevalent form of cartilage in the body is hyaline cartilage.

<h3>What is hyaline cartilage?</h3>

On the articulating surfaces of bones, in the larynx, trachea, and bronchi, as well as on the sternal ends of the ribs, hyaline cartilage is present. It imparts a rigid yet malleable form to the constructions.

Hyaline structures are connective tissues that anchor the ribs onto the sternum. Such structures and joints are robust because collagen fibers are present, but their mobility and flexibility are constrained. To reduce friction and provide cushioning at the joint surface, articular cartilage, also known as hyaline cartilage, covers the ends of bones.
