Answer:
Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).
Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.
In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.
Answer:
The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus.
The nucleus is where cells store their DNA, which is the genetic material.
The nucleus is surrounded by a membrane. ...
Explanation:
All prokaryotes are single-celled (unicellular) organisms.
Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.
Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.
As a result, the only renewable product in the choices provided above is a wooden spoon.
Hi there!
The example of the meadowlarks is an example of behavioral isolation. This is because the mating call is a behavior the birds exhibit. This helps the birds to find their correct mate because though the birds look similar, they are not able to produce offspring.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
