Answer:
The correct answer is ''carbon dioxide, water vapor and nitrogen.''
Explanation:
About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.
A, B, and C. Luster is the light and how light reflects off of it, right?
So, in that case, a non metallic mineral, (think coal) wouldn’t shine much. A metallic mineral would shine, because it’s metal. And something that’s shiny obviously shines.
Go with A B and C.
Answer:
Meiosis II.
Explanation:
Meiosis may be defined as a type of cell division in which four daughter haploid cells are produced from the single diploid cell. Meiosis is also known as reduction division as the chromosome number is reduced to half as compared with the original parent cell.
Meiosis is divided into meiosis I and meiosis II. The meiosis is similar to mitosis as the each cells contain only one set of the homologous chromosomes.
Thus, the correct answer is option (3).
