Cara is explaining to her sister how the solar system formed. Which description would she use to explain the solar nebula
Alexandra [31]

Answer:

The correct answer is A. a rotating cloud of dust and gas.

Explanation:

Nebulae are regions of the interstellar medium (clouds) made up of gases (mainly hydrogen and helium) and dust. In other words, nebulae are concentrations of gas in which we find hydrogen, helium and stardust in greater quantities. They are structures that are actually very important for the universe, this because inside it is the place where stars are born, which arise due to the condensation and aggregation of matter. The nebular theory states that the Solar System reached the form current from a solar nebula (a gas cloud), more than 4.5 billion years ago. The large cloud of molecular gas was affected by a certain phenomenon that would have taken place in the vicinity. Like the explosion of a supernova or the passage of a star that would produce a strong gravitational impact. The result of this event made the matter agglomerate in different places. The high concentration of matter caused the nebula to collapse. Becoming a protostar, (bodies whose characteristic is to be surrounded by clouds and contain preplanetary matter inside), that is, gaseous matter in the outermost part and solid inward. At the core of this structure, the temperature is so dominant that nuclear reactions take place to compensate for the gravitational force. This leads to a hydrostatic equilibrium and the formation of a fundamental star: the Sun. The rest of the mass flattened, forming a protoplanetary disk where the protoplanets were being formed, which would evolve to become the current planets, their satellites and the others bodies of the solar system.

How many chromosomes, and which chromosomes, does each of the dughter cells contain
labwork [276]

The question is incomplete. However, if we consider this cell as human cell - the cell contain 23 pairs of chromosomes.

Answer:

Chromosomes consists of the constricted DNA associated with the proteins. Different species has different chromosome number. Two main types of chromosomes are heterochromatin and euchromatin.

The human cells contain the 23 pairs of chromosomes or 46 chromosome. If the cell divides by the process of mitosis than the chromosome number will be same in parent as well as the daughter cell. The daughter cell 23 pairs of chromosomes. If the cell divides by the process of mitosis the cell has 23 chromosome number as the meiosis reduces the chromosome number upto half.
