Answer:
Energy is stored in covalent bonds between carbon atoms
The myelin sheath that covers many cns axons is formed by oligodendrocytes.
Oligodendrocytes are type of neuroglia (non-neural cells found in central nervous system) with protective, trophic and supportive role. Their function is to insulate axons (with myelin sheath), in the central nervous system (CNS) which is, equivalent to the function performed by Schwann cells in the peripheral nervous system (PNS).
Answer:
a) Some island populations will have fixed one allele, and other populations will have fixed the other allele.
Explanation:
The founder population for each island is heterozygous for the locus. The absence of any migration and mutation would result in no gene flow or the introduction of new alleles of the locus. Over several generations, one or the other allele will be fixed in the populations depending on the adaptive features imparted by each under the different conditions present on these different islands. Genetic drift may also work on these small founder populations to randomly fix one or the other allele.
Answer:
A & B
Explanation:
A - When a CME hits the Earth's atmosphere, it results in a (temporary) disturbance of the Earth's magnetosphere - a geomagnetic storm.
B - In basics, solar wind drags the magnetic field lines of coronal holes so far out that it surrounds all of the planets in the solar system, forming an IMF.
All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators. and other species that compete for the same food and space
