Answer:
The correct answer is conservative model.
Explanation:
There are 3 hypothesized DNA replication models: semi-conservative, conservative and dispersive model (see figure). Heavy isotope of nitrogen makes diference when density gradient centrifugation experiment conducted and two diffent bands contaning different isotopes of nitrogen are observed. With one band only containing 14N means bacteria only copies one strand in one replication which supports semi conservative model.
When two atoms react, they form either of two kinds of bond, ionic bonds or covalent bonds.
Ionic bonds are the type of bonds where there is transfer of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.
Covalent bonds are the kind of bonds formed when two atoms share electrons. Here there is sharing, none of the atoms loses an electron and none gains. A good example is water which is formed when oxygen shares two electrons, each with an atom of hydrogen.
The Oxygen atom forms two covalent bonds with the pair of hydrogen atoms.
The mother of the bunnies is white while their father is black. The independent assortment of the genes during the formation of gametes ensures that each parent contributes same amount of the genetic information to the offspring. The more number of black bunnies than white is because of the dominance of the gene coding for the black fur trait over the white fur trait.
Hence, the correct answer is 'Option F'.
Plants give animals the food and shelter they need. Herbivores, which are plant eating animals, rely on plants to provide them with a regular source of food. They also provide shelter to may animals, both large and small.
To avoid this u need to drink LOTS of water
