1. Early earth had no ozone layer, which means it was most likely extremely hot.
2. Young earth had no oxygen and life needs oxygen in order to survive.
3. There where so many natural disasters happening all the time, like volcanic eruptions and constant impact with meteorites and asteroids.
-Extra one (4. Earth originally had no ocean and water. Oceans eventually formed from the water vapor released from the volcanic eruptions, but before that there was nothing.)
During telophase in mitosis or meiosis II, where chromosomes which were previously distinct and condensed, de-condense and spread out into a tangle of chromatin. At the same time, the nuclear envelope re-forms around each cluster of chromosomes in each of the daughter cells, and spindle fibres disintegrate.
Chromosomes are unlikely to de-condense and spread out into a tangle of chromatin during telophase I (i.e. Telophase of Meiosis I), since Meiosis is still ongoing, and the genetic material should be in its condensed form during Meiosis II as well.
Hope this helps! :)
It helps scientists improve on research and tests/examinations to understand the object a little more. For Example: The newer modified microscope helps zoom into harder to see microrganisms. So if technology changed then most of our scientific knowledge wouldve been mistaken this whole time. We wouldnt know many things if technology didnt exist.
Excess carbs and fats are stored; excess proteins are not.
Excess calories are transformed as fat when in excess, which includes protein.
Answer:
C. transcribed, mRNA
Explanation:
DNA, also known as deoxyribonucleic acid, is a molecule that holds genetic information needed to make other molecules in living organisms. However, before this genetic information can be harnessed, it needs to be expressed via two processes called transcription and translation.
Transcription is the first of the two processes that take place during genetic expression. It involves the synthesis of mRNA molecule from a DNA template. In other words, the DNA must first be TRANSCRIBED into mRNA.
