Assoli18 [71]

Answer:

A higher rate of concordance in monozygotic twins in comparison to dizygotic twins is a proved evidence of the contribution of the genetic constituent as monozygotic twins are genetically more identical in comparison to dizygotic twins. The monozygotic twins share all the genes in common and dizygotic twins on average share half of their genes in common.  

Thus, the concordance in monozygotic twins is more in comparison with that of dizygotic twins, which shows the contribution of genetics to this trait.

Which of the following are some examples of rapid environmental changes? Please select all that apply.
Stolb23 [73]

Answer:

fire

landslide

avalanche

Explanation:

Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.

On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.
