Answer:
The mice died
Explanation:
In Griffith's experiment, two strains of the same bacteria were used. S strain was smooth because it had a polysaccharide coat. This coat also made it virulent because mouse immune system was not able to destroy it and ultimately the mice died. R strain was rough because it did not have the coat and thus was harmless to mice.
When Griffith injected mice with dead S bacteria and living R bacteria together, the mice died. Live R bacteria had taken up the genetic material or as Griffith called "transforming principle" from the dead S bacteria and transformed into S bacteria. So live S bacteria were present again and they killed the mice.
There are different materials of raw water, but also the raw water comes from ponds,rivers, and oceans but they might be good sometimes, and gas not been treated and has bacteria or mold buy that is not good.
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.
A. Earth's magnetic field reverses over time; the changes show that seafloor spreading has taken place over time.
Explanation:
The pattern of the magnetic minerals in seafloor ridges are aligned in a repeating pattern because the earth's magnetic field reverses overtime.
This provides evidence because the changes shows that the sea floor spreading has taken place over time.
- The concept of sea floor spreading was first suggested by Harry Hess in the early 1960's.
- Using sophisticated tools, he was able to discover stripe patterns of magnetic minerals in rocks.
- The earth can be likened to a giant bar magnet
- The geomagnetic field originates from the core where the movement of molten metals induces magnetism.
- In a fresh cooling magma, the metallic minerals are able to align their domains with the prevailing magnetic field.
- At some point the magnetic field is normal with a very strong intensity. At other times the intensity is low and it reverses.
- The minerals keeps track of the changes.
- This leads to striped pattern that has been used to suggest sea floor spreading.
