All of the are false lowest it can be without a human ear picking up is 19 hertz
The Genotype of the father is gg; The possible genotypes of offspring will be
Gg; gg; Gg; gg. Therefore there is a 50% chance that the child will have galactosemia. The parents could have had; both had gg genotype,or both had Gg genotype, or one had gg and the other Gg.
Well there are 4 things in a dna molecule and that is adenine guanine thymine and cytosine well the DNA molecule keeps the cell moving in the right direction and also helps the cell reproduce and stay healthy
The main arctic animals which will be affected by climate change are polar bears, seal, seabirds, and walrus.
Polar bears: Sea-ice cover at summer may be completely loss and this inhibits polar bears traveling from region to another to give birth — making the survival of mothers and cubs to be vulnerable.
Seal: Seal species are living mainly on ice and with the climate changing, ice cover also reduces — creating a not so comfortable environment for seal. They use sea ice as a feeding ground, birth place and a place where for raising their young, as well as for resting.
Seabirds (auks and gulls): They eat fishes and scavenge on top of sea ice, so when sea ice reduces so as their source of food and population.
Walrus: Uses sea ice as a feeding ground and source of food is on the sea floor while using sea ice as a diving platform. So any loss of sea ice cover, also affects their way of feeding and eventually, their population.
Overall, melting of ice affects salinity and temperature of surface waters, thereby affecting other marine life.
