Very true.
It harms our atmosphere, thus effecting climate. Which can kill and sometimes nearly cause organisms to go extinct. It corrupts our air, which is very unhealthy, and can cause lung cancer, and harm our breathing patterns. Which can shorten life expectancy.
Stay clean, and I hope this helps! :) <span />
The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
Answer:
its basically a layer that helps to absorb light energy there have a pog day friend
Answer:
allows the recombination of genetic information
Explanation:
Crossing over is a process that occurs only in meiotic division in sexually reproducing organisms. It is the process whereby the segments of a gene are exchanged between the non-sister chromatids of homologous chromosomes.
Due to this crossing over process that occurs in prophase I of meiosis, the alleles of a chromosomes are recombined to ensure genetic diversity. Hence, according to this question, crossing over results in additional genetic variation during meiosis because it allows the recombination of genetic information.
The correct terms would be second and sensation. When pressure waves in the cochlea move to the basilar membrane, stimulating the sensory receptors in the inner ear, it would be the second step in the hearing process where sensation happens. The second stage is called the interpreting stage. In this step, you make meanings of what you are hearing.
