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.
<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or
radioactive dating is used, for example, rocks or carbon, in which trace
radioactive impurities were specifically fused when they were framed. The
strategy looks at the abundance of a normally happening radioactive isotope
inside the material to the abundance of its decay items, which shape at a known
consistent rate of decay.</span>
The answer is <span> b) chromosomes replicate
DNA replication occurs before mitosis. So, duplicated chromosomes are already present in mitosis. They are connected by centromeres. During different phases of mitosis, spindles are formed and pull chromosomes toward the opposite poles of the cell so centromeres must split.</span>
Well everyone's needs for love and attention are different. It can depend on how you were raised, if you received a lot of attention as a kid, etc. Humans are social creatures so we already crave human interaction. and, going back to how you were raised, even if you were raised quite well and you got enough attention as a kid, it really depends on how people treated you and maybe how many times you've had your heart broken or something along those lines. That need honestly varies from person to person. But I know how it feels, you'll get through it, you'll be okay.
