The replication fork is a structure that forms within the nucleus during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together. The resulting structure has two branching "prongs", each one made up of a single strand of DNA.
Answer:
D. increasing the number of mitochondria
Explanation:
The mitochondria are membrane-bound cellular organelles found in the cell of an eukaryote. Mitochondrion is responsible for the production of energy since the process which releases the energy (cellular respiration) occurs in it.
In an experimental procedure whereby the amount of energy which is produced by a cell is about to be increased will involve the increase of the number of mitochondria in that cell. Since more mitochondria means more energy production.
Gravity
Gravity is a force associated with all matter, pulling matter together. The force (which is a property of mass) is directly proportional to mass.
Explanation:
As the star fuses helium atoms in its center, enormous energy is generated and the atoms have a very high kinetic energy and want to escape from the center hence create great outwards pressure. However, the great mass of the center of the star creates enormous gravitation pull towards the center of the star. This gravitational force keeps the high kinetic atoms from escaping. The atoms keep fusing until the fuel is exhausted and the star ‘dies’.
