The ice has less density than liquid water, so it floats on the water surface. Therefore during the winter all the lakes and rivers are frozen only at a top. Deeper layers of water are cold, but still liquid and it allows fish and other organisms to survive. Moreover, the ice cover provides temperature isolation so liquid water beneath the ice has more or less constant temperature (around 4 dgr Celsius)
The reading frame of the sequence would shift, causing a change in the amino acid sequence after that point.
Explanation:
DNA sequencing is important to apply to the human genome. It allows scientists to sequence genes and genomes. Since there is a limit to how many bases can be sequenced in one experiment, larger DNA molecules - as mentioned - have to be 'broken' into smaller fragments before they can be sequenced and re assembled. The normal allelic variant is 1600 base pairs (bp) long and contains three exons. The order of the genes in the beta-globin cluster is 5' - epsilon – gamma-G – gamma-A – delta – beta - 3'.

Answer:
Signposts that determine the fate of cells.
Explanation:
Embryos for humans and other animals often look alike at certain developmental stages because they share ancient genes. This expression means that a more advanced organism, like humans, will resemble less advanced species during it's development stages.
Homeostasis it is an organism's ability to keep a constant internal environment.
