Answer:
Semi-conservation replication describes the mechanism of DNA replication in all known cells. This process is known as semi-conservation because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
DNA is passed down to the next generation in big chunks called: Chromosomes.
Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around a 1 in 8 change that you would get no DNA from a great, great, great, great grandparent.
What most people forget, through, is that our chromosomes get mixed and matched before they are passed on. It is because of this "recombination" that your great, great, great grandparent's DNA is almost cetainly still lurking in yours.

I majored in Biology
The wrinkles signify that the brain is compressed which makes it take up less space in your head which makes it more eficent I guess.
Answer:
Darwin's Natural Selection Worksheet Read the following situations and fill in the chart for each of the four parts of Darwin's theory of
natural selection.
D There is a species of worms that eat at night (nocturnal) and ones that eat during the
day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal
worms. The nocturnal worms are in their burrows during this time. Each spring when
the worms reproduce, they have about 500 babies but only 100 of these 500 ever
become old enough to reproduce.

Explanation:
DNA is basically the hard copy. It is double stranded and found in every cell. It contains a library of EVERY single protein that the body makes. Cells supress bits of the DNA because every protein does not apply to every cell.
<span>mRNA is the portable version that is taaken away from the hard copy to make the actual protein. It is single stranded and codes for 1 protein (although in bacteria one mRNA can code for many proteins). It is the actual bit that gets TRANSCRIBED in the nucleas (copied) and TRANSLATED (written) into proteins in the cytoplasm on ribosomes (which are incidently another form of RNA...rRNA). </span>
<span>DNA functions include getting copied to every daughter cell too

Some examples of polygenic traits are height, skin color, eye color, and hair color.
1) I have blue eyes and my mom also has blue eyes.
2) My sister has dark brown hair while, I have light brown hair.
