Answer:
Solidifications of molten materials.
The right answer is A.) DNA in mitochondria
.
Eukaryotic cells, with their many intracellular organelles, have long been considered progeny of prokaryotes that would have become more complex as a result of genetic mutations. But from the 1960s, biologist Lynn Margulis proposed an alternative explanation that was first received coldly by the scientific community. His endosymbiotic theory, proposed in a more formal way in a 1981 book, proposes that eukaryotic cells as we know them today would be the result of a series of symbiotic associations with different prokaryotes.
Mitochondria and chloroplasts also have their own DNA that is not trapped in a nucleus, which is also the case with prokaryotes. However, the proteins encoded by this DNA do not cover all mitochondrial proteins. The prokaryote is thought to have lost some genes to the nucleus of the cell, a process known as "endosymbiotic gene transfer". For this reason, mitochondria and chloroplasts are now host-dependent for the synthesis of most of their components.
I would say D is da best answer not rlly 100 but dats seems da best 2 me
The answer is cervix. It is cylindrical in shape and found
at the base of the uterus and where the
vagina begins. It is 2 – 3 cm long. The cervix enlargens during pregnancy to
allow the passage of the fetus during childbirth.
It is also a conduit for sperm from the vagina to the uterus as they swim
upstream to fertilize the egg.
<span>D. In a study of the effect of lawn fertilizer on the health of a
backyard pond, biologists grow two colonies of duckweed in a large flask to
represent pond ecosystems. </span>
The scientific design in which has limitations
due to oversimplification is the statement “in a study of the effect of lawn
fertilizer on the health of a backyard pond, biologists grow two colonies of
duckweed in a large flask to represent pond ecosystems”. Oversimplification is
an overview and generalization of a statement to miscomprehension,
misperception or even error. It overlaps the true statement.
