That would be C. Uracil.
In RNA we’ve got Uracil instead of Thymine.(which is in DNA)
Answer:
DNA replication is the process by that DNA make a copy to the cell division.
Explanation:
- DNA replication is the double structure to the DNA molecule,it is biological process.
- DNA replication molecule the serve that template for the production to referred conservative replication.
- DNA replication occurs living the biological property of division and they performed complementary stand.
- DNA replication to that begin the specific location and origins in the genome, and growing from the origin.
- DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.
- DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .
- DNA replication is the basis of single strand to 3 prime and 5 prime end, these refer to the carbon atom in the chain attaches.
- DNA replication allow the strand to the one another strand to used in partner strand.
- DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.
The answer is B. Geology has shown a thin layer of iridium (a rare mineral on earth but found on asteroids and meteors) in the rock layers between the Cretaceous and Paleogene periods. Below this layer are numerous fossils of pterosaurs and dinosaurs, but above the layer are drastically few. The aftermath of asteroid impact is believed to have smothered most vegetation from earth which dinosaurs depended on as a source of food.
Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
<span>The exfoliative toxin is responsible for a skin disease called staphylococcal scalded skin syndrome. This exotoxin, exfoliatin is produced by Staphylococcus aureus and it induces the formation of fluid-filled blisters with easily ruptured, thin walls, usually in infants. Exfoliatin has the protease activity which causes peeling of the skin by destroying adhesion between keratinocytes (skin cells).</span>
