Answer:
The correct answer is - microevolution.
Explanation:
Microevolution is the very small evolutionary change specially allele frequencies on the level of species that occurs slowly over period of time. These changes occurs on the level of DNA or genetic level.
These evolution can be caused by the natural selection process or genetic drift over the generation of the species or population over period of the time. It is the study of the evolution that occurred on level of separated gene pool.
Thus, the correct answer is- microevolution.
Plant #1 would locate in a damp and probably contain no undergrowth. Example forest.
Plant #2 would locate in a dry area such as a desert example cactus, as the waxy coating keeps water and the spines suck up water and protect the plany
Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
Explanation:
1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.
2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.
3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.
Answer:
macroevolution
Explanation:
Macroevolution occurs due to the genetic differences accumulates in the population of the same species which gets reproductively isolated from the older population and got different environments and resources to live.
Macroevolution leads to the creation of a new species over a long period of time because of the genetic difference that occurs due to mutation in the gene in the population who got reproductively isolated. So the new species evolved from the macroevolution.
