The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination.

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.

Katena32 [7]
<span>#1) With reference to the role of oncogenes, explain how the normal controls over the cell cycle can be lost.

Answer: The way that cell cycle can be lost is by going through changes in the activity of cell cycle regulators. Cancer causes different types of mutations. There are two types of cell cycle regulators that can promote the development of cancer:

-Positive Regulators that can be over activated (become oncogenic).
-Negative Regulators (tumor suppressors) which can be inactivated.

I hope it helps, Regards. <span /><span>
