Answer:
Meiosis I, a reductional division of two haploid cells produces offspring cells that are not genetically identical with the event of recombination. Haploid girl cells have half the original/parent cell chromosomes.
Explanation:
meiosis II, an equational or mitotic division, divides the haploid cells created in meiosis I to produce four identical daughter cells that ultimately form the male/female gametes (egg/sperm).
Here chromatids split in contrast to meiosis I when homologous chromosomes apart.
Answer:
The correct answer will be- formation of membrane
Explanation:
The three-stage origin of life theory suggests that life on Earth originated in three phases which are:
1. Phase I: The larger molecules formation began during this unsuitable earthly conditions full of volcanic eruptions and harmful gases underwater.
2. Phase II: The self-replicating molecule begins to form during this phase which contained the coding of life. The self-replicating molecule is known as the formation of the membrane.
3.Phase III: The formation of the membrane which help separate the outer environment from the inner environment was observed during this phase.
Thus, the formation of a membrane is the correct answer.
Answer:
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
Answer:
Mammals evolved from a group of reptiles called the synapsids. These reptiles arose during the Pennsylvanian Period (310 to 275 million years ago). A branch of the synapsids called the therapsids appeared by the middle of the Permian Period (275 to 225 million years ago)
