One way is that Igneous rock could erode and become sediment and deposited and slowly change into sedimentary rock, then get pushed down deep into the crust and changed by heat and pressure into metamorphic rock.
Yes I do we have about 71% of the world is water and from that water 96.5 is ocean water and about 4% is fresh water it is mostly found in Glaciers <span />
Complete question:
Two species of closely related frogs are found in the same pond high in the Andes of South America. Both species only have teeth on the top jaw. One has small teeth for holding small live prey prior to swallowing. The other species has very large sharp teeth for injuring and killing large prey prior to biting off pieces of flesh for consumption. The above is an example of:
- Directional selection
- Analogous structures
- Character displacement
- Hybridization
- Vestigial structures
Answer:
Explanation:
Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.
The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When <u>two competing species coexist, this is because of niche partitioning or niche differentiation</u>.
Differentiation of effective niche is closely related to <u>character displacement.</u>
<u>Character displacement</u> is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.
In the exposed example, both species live in the same pond. But to avoid competition and competitive exclusion, species developed different teeth sizes to feed on different prey items.
Answer:
The uterus is an organ used for producing offspring.
Explanation:
It’s also called a womb, offspring develop within it until they are ready to be born.
Explanation:
Genetic conditions such as trisomy (three chromosomes) or monosomy (only one chromosome). They can also determine the fetus' gender by looking at the XY / XX chromosomes.
