Q: The rate of evolution is influenced by the rate of changes to what? Read this paragraph and choose the correct option from the provided answers: The rate of evolution is influenced by how quickly the environment is changing. Long periods of gradual evolutionary change may be interrupted by short bursts of rapid change. Choices: - dna - migration - the earth - the environment A:
(A).
the environment

Q: Which is the final step of cell division? Read this paragraph and choose the correct option from the provided answers: Cytokinesis is the final step in cell division. It often occurs concurrently with telophase, though it is a separate process. Cytokinesis ( Figure below ) differs between plant and animal cells. In animal cells, the plasma membrane pinches inward along the cell's equator until two cells are formed. Specifically, a cleavage furrow containing a contractile ring develops in approximately the middle of the cell (similar to the position of the metaphase plate), essentially pinching off the two nuclei and forming separate cells. In plant cells, a cell plate forms along the cells equator. A new membrane grows along each side of the cell plate, with a new cell wall forming on the outside of each new membrane. Choices: - genesys - Mitosis - electrolysis - cytokinesis A:
(A).
cytokinesis

Q: What term did schrodinger use for regions around the nucleus where electrons are most likely to be? Read this paragraph and choose the correct option from the provided answers: Schrodinger developed an equation that could be used to calculate the chances of an electron being in any given place around the nucleus. Based on his calculations, he identified regions around the nucleus where electrons are most likely to be. He called these regions orbitals . As you can see in the Figure below , orbitals may be shaped like spheres, dumbbells, or rings. In each case, the nucleus of the atom is at the center of the orbital. You can see animated models of orbitals this URL: http://www. chemistry. wustl. edu/~edudev/Orbitals/movie. html . Choices: - arrays - isotopes - ellipses - orbitals A:
(A).
orbitals
