Answer:
option c punctuated equilibrium
Explanation:
Punctuated equilibrium occurs in a process whereby evolutionary changes occurs in some organisms in a rapid burst of time rather the conceived gradual changes that occurs over a long period of time. this burst of time might be in about 500,000 years. It is assumed that the organism has maintained/lives in stasis for a long period without a need for change, but then, once the change takes place (most of the time, due to an environmental factor), the organism quickly adapts to its new environment with this new adaptation.
So we’ll just use “R” and “r” for this example. If the mother AND father are heterozygous, then both of their genotypes are “Rr” if you work out the lumber square or use the foil method, the box would look like this: RR on top left, Rr on top right, Rr on bottom left, and rr on bottom right. So the genetic probabilities, using four as the sum would be 1:2:1
Answer:
In reality, natural gas power plants will likely operate for at least 50 years, reducing the already minimal construction-cost impacts even further. ... In short, the decade-long economic benefits of replacing coal power with natural gas power will continue in future decades as well.
Explanation:
Answer:D. tapeworms live inside a goats body in a close relationship the goat.
Explanation:
In parasitic relationships,the parasite lives on the host and benefits from the host while causing harm to the host .the host does not benefit.the parasites are usually in close relationship with their host as their food source are substances of the host organisms.
The parasite may live in the host , these are called Endo-parasites.
The parasite may live outside the host, these are called ecto-parasite. In this example, the tapeworm is an endo-parasite that lives in the digestive tract of the goat. It absorbs digested food in the intestine through it's body surface.
In predator and prey relationship, the predator usually has to hunt for the prey and feed on it. It may kill it first or may not
