It's the amount of matter that makes up the object
if the same object is placed in different force of gravity rate, the mass will still be unchanged.
Answer:
time between eras and biodiversity that exists on each period of the geological time
Explanation:
A geological era is a formal geochronological unit of the geological time scale that represents the time corresponding to the duration of an era, the equivalent chronostratigraphic unit comprising all the rocks formed at that time. The ages are one of the major divisions of geological time, they are subdivisions of the eons and they are divided into periods.
The three eras of the Phanerozoic eon variables, simplifying much, the three classic divisions of the history of the life of the planet:
1. Paleozoic represents the "age of fish"
2. Mesozoic the "age of reptiles"
3. Cenozoic the "age of mammals."
Traditionally they had been referred to as Primary Age, Secondary Era, Tertiary Era and Quaternary Era (currently the Quaternary is another period of the Cenozoic era). The passage from one era to another is defined by events of global mass extinctions, which entail a significant renewal of the biota of the planet, both marine and terrestrial; thus the passage from the Paleozoic to the Mesozoic is marked by the mass extinction of the Permian-Triassic and the passage from the Mesozoic to the Cenozoic by the mass extinction of the Cretaceous-Tertiary.
Answer:
Vacuoles
Explanation:
Vacuoles have enclosed compartments which are filled with water containing inorganic and organic molecules including enzymes in solution.
Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
