The answer is D. All living things are made up of cells
What are the theories of evolution ?
it is the same question .
Explanation: In biology it refers to absorb changes in organisms , to there descent from a common from a common ancestor , and at a technical level to a change in gene frequency over time , it can also refer to explanatory theories [ such as charles darwin 's theory of natural selection ] which explain the machanism's of evolution .
Answer:
Roosting areas in buildings of any height are the resource partitioning of both bat species.
Explanation:
- The <em>fundamental niche</em> refers <u>only </u>to <u>physic conditions</u> in which a species can live and survive in the absence of any interaction with other species.
- The <em>realized niche</em> refers to the <u>restricted conditions</u> in which a species can live and survive as a result of <u>environment physic characteristics</u> and the <u>interaction</u> with other species.
- <em>Competitive exclusion</em> refers to the <u>exclusion</u> of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor.
- Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use resources -partially or completely-, migrates or get extinguished.
A way in which species can divide resources is by living in different habitat areas. These species <em>might eat the same food</em>, and <em>can roost in different places</em> within the same habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.
In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.
Answer: False
Explanation:
Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.
These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.
These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.
