Milankovitch cycles describe the effects of changes as a result of climate change. There are three Milankovitch cycles:about Earth's Eccentricity (the shape
of the Earth's orbit around the Sun), Axial tilt (the inclination of the Earth's axis in relation to its plane of orbit around
the Sun) and precession (the Earth's slow wobble as it spins on axis).
According to this, Milankovitch's cycles <span>are changes in earth's rotation and orbit around the sun that may trigger climate variation. (B).</span>
Answer:
mutualistic
Explanation:
The interaction between two organisms in which both the organism gets benefitted from each other is called a mutualistic relationship. This mutualistic relationship is seen in the concept of endosymbiosis.
According to the endosymbiotic theory chloroplast and mitochondria are evolved by engulfment of different bacteria by ancestral cells. Then these bacterial remained in a mutualistic relationship with each other and the ancestral cell evolved into a eukaryotic cell.
So as mitochondria and chloroplast live with a symbiotic relationship with eukaryotic cells, therefore, it is considered as mutualistic relationship.
The answer is either b or d
Answer:
If the original finches that had been blown over to the Galápagos from South America had already been genetically different from the parental population of South American finches, even before adapting to the Galápagos, this would have been an example of
E) both the first and third of these.
Explanation:
Genetic drift was the process of changing of allele frequencies over generations in a random fashion.
Founder effect is closely linked with the genetic drift. In this case, a few individuals of the original population start a new colony isolated from the other members of the species.
A founder effect happens when a new colony started from few members of the original population. The small size of population means that the colony may have a small variation of the genes in the original population.
A founder effect event happens when a small group of individuals was separated from the rest of the population, whereas a bottleneck effect occurs when most of the population is destroyed.
