The correct answer is A. Bacteria live in root nodules of a plant, process nitrogen to ammonia for the plant, receive protection and steady food supply which is being got in return.
Mutualism is referred to as the way two organisms which are of different species exist in relationship whereby every individual benefits from activity of each other.
The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism.
Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.

the formation of bone from preexisting fibrocartilage models
the formation of bone from fibrous membranes
Explanation:
Answer:
Explanation:
The cause of current climate change is largely human activity, like burning fossil fuels, like natural gas, oil, and coal. Burning these materials releases what are called greenhouse gases into Earth's atmosphere.
Population sizes will increase as new species move into the cleared area.
Invasive species will quickly take over the disturbed area.
Biodiversity will decrease in the area of the fire.
Answer:
Biodiversity will decrease in the area of the fire.
Explanation:
Biodiversity will be reduced in the area affected by fire, mainly due to factors such as habitat destruction, pollution and exploration of natural resources.
Habitat destruction occurs as a result of the urbanization, deforestation and development of large agricultural works, this destruction is also caused by globalwarming (or climate change).
In addition, air, soil and water pollution also cause biodiversity loss.
Due to environmental pollution, many species cannot establish themselves, for example due to lack of food, difficulty in accessing drinking water or the emergence of diseases.
Biodiversity can also be threatened by overuse of natural resources such as logging, reducing the number of plants in an ecosystem.
Uncontrolledhunting and fishing are also responsible for reducing the number of individuals of various species.
Biodiversity will decrease in the area of the fire.
a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
b. Birds and sharks do not share a common evolutionary ancestor.
c. Having a bony skeleton did not provide an evolutionary advantage to sharks or ray-finned fish.
d. Rabbits and primates diverged more recently than crocodiles and birds.
Answer: a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
Explanation:
A cladogram is a diagrammatic representation of the phylogenetic relationship of recently evolved species with their common ancestors. The relationship is defined on the basis of genetic, molecular, morphological make up of the organisms. The node in the cladogram defines a divergence or difference between the two taxon.
Birds and amphibians share a more recent common ancestor than shark and birds because they can be seen lying closer at the terminal ends of the cladogram.
