Answer:
The correct answer is hydrogen bonding.
Hydrogen bond is defined as a weak bond that results from electrostatic attraction taken place between hydrogen of one molecule and electro-negative atom of same or different molecule.
In water, partial negative charge is present on oxygen atom which attracts the partial positive charge present on hydrogen atom of other water molecule. This attractive interactions lead to the formation of inter-molecular hydrogen bonding.
Answer:
B. A biodiverse ecosystem harbors many interactions, thus a disturbance may impair some interactions, but not all.
Explanation:
Biodiversity is the variation of life forms in an environment. This is as a result of available nutrient and energy to support the various life forms.
- The relationship between biodiversity and rebound from disturbance is such that a biodiverse ecosystem is able to resist any change.
- The disturbance might affect proportion of the populace. But on the long organisms can survived and be propagated again.
Answer:
D. Changes in the environment changed each morph's ability to evade predation in different ways.
Explanation:
The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.
When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.
Therefore, option D is best option.
