Answer:
DNA replication is described as semi-conservative.
Explanation:
DNA replication is described as semi-conservative because each double helix formed comprises one strand from the helix from which it was copied and a new strand. That is, the replication of one helix results into two new copies of which each contains one of the original double stranded helix from which it was synthesized.
1.Magnification is the ability of optical instruments, such as a telescope or a microscope, to make an object bigger while resolution is the ability of optical instruments to produce images that are clearer, finer, and sharper.
2.Resolution is the power of an optical instrument to capture and produce more details of an image while magnification is the power of an instrument to create and produce a much larger image of an object.
3.Resolution can be expressed in arcsec or seconds while magnification can be expressed by a whole number and the letter “X.”
4.Although both are dependent upon each other, a high magnification does not always guarantee a high resolution.
5.Magnification allows us to see small objects, especially those that are not visible to the naked eye, while resolution allows us to see these objects more clearly and with more details.
Answer;
-Large polar molecule are list likely to cross the phospholipid bilayer.
Explanation;
-A large polar molecule would be the least likely to passively diffuse through a plasma membrane without the help of a transport protein. Both its size and the hydrophobic interior of the membrane would restrict it.
-Only small uncharged molecules can diffuse freely through phospholipid bilayers. Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes.
-Ions and large polar molecules cannot pass through the lipid bilayer. But more specifically, whether a molecule can pass through the membrane depends on its size and its electrical nature.
D.lets things enter or exit the cell
Answer:
Nucleus
Explanation:
Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.
So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.
So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.
