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.

Answer:
The stigma, a female structure which collects pollen and passes it to the ovary
Explanation:
<u>The structure represented by the letter A in the diagram is the stigma.</u>
The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.
<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>
As we get closer to the coral reef, there are going to be several things we notice. The first thing we notice will be the large number of coral that seem to have lost their color, turning bright white. In addition, if we are in Florida, we may see something called the stony coral tissue loss disease. This disease has been of great concern in recent years in Floridian waters. Looking at these two changes, we can see that both are from the impact of climate change. As the water warms, the stress on the coral reaches a high point and they start to bleach and become more susceptible to several diseases.
I hope I've helped! :)
