Answer:
D
Explanation:
Bohr determined that there are discrete (unique, different from one another) energy levels in the atom and that electrons will orbit the nucleus within these energy levels, known as orbitals.
In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.
An ectotherm gets its heat from external sources
(Remember "ecto" means outer, "endo" means inner)
The given statement is false.
The fires are essential to both the grassland and savanna ecosystems. The grasslands and savannas are featured by two seasons, which are sustained by fire, and exhibit species that are impervious to drought. These fires help in following on the sequences and permit for habitats to maintain their resolution.
The African savanna ecosystem refers to a tropical grassland with warm temperatures over a year, and with its highest seasonal rainfall in the summers.
