Answer:
Two DNA molecules, containing the same genetic code as the original DNA molecule, are produced.
Explanation:
DNA replication is a very important process that must occur in every living cell prior to cellular division. It is the process by which a DNA molecule makes another copy of itself i.e. duplicates itself, to form two identical molecules of DNA.
In the process of DNA replication, the double-stranded molecule first unwinds to form two single strands of DNA. Each DNA strand serves as a template for making another complementary strand of DNA. At the end of replication, each copy of DNA molecule contains one new strand and one old strand. Both copies contain the same genetic code as the original DNA molecule.
Answer:
Gram-positive bacteria have a single cell wall anchored to the cell membrane by lipoteichoic acid.
Explanation:
According to Gram stain test, bacteria can be divided into two main groups which differs mostly in the structure of the cell wall"
- Gram-positive bacteria-thick cell wall which consist of peptidoglycan layer that is attached to cell membrane via teichoic acids (lipoteichoic acids). Because of their thick wall, after the staining, the violet dye retains, so Gram positive bacteria appear purple-coloured.
- Gram-negative bacteria-thin peptidoglycan layer with two cell membranes: inner and outer membrane (lipopolysaccharides). Usually, Gram negative bacteria contain porins. After the staining, the dye does not retain, so this type of bacteria appear red coloured.
Answer:
Nevada
Explanation:
it is in the same location when u look at it from a map point of view.
the following image should help. the focus is the exact location where the plate grinds. the epicenter is right above the focus, just on the surface.
hope this was worth ur last points
The primary source of energy in a food chain is Sun, because producers are the ones that prepare food by themselves and that food is then passed on to higher levels in food chains. And as the producers make their from Sunlight, the primary source of energy in food chain is <u>Sunlight</u> .
