Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.
Answer:
C
Explanation:
Gymnosperms generally refer to a group of terrestrial, seed-producing vascular plants whose means of reproduction is an exposed ovule known as a cone.
There are 6 divisions within the gymnosperms, including cycads, ginkgos, and pinus (conifers). Gymnosperms are generally non-flowering and produce needle-like leaves. Their species are usually woody or perennial shrubs/herbs
This is <u>unlike the angiosperms</u> that are usually classified into 2, including the eudicots and the monocots. The division is based on the number of cotyledons or seed leaves carried by the plants in the group during germination.
<em>The correction option here would, therefore, be C. </em>
Fertile land is lost, and there is increased pollution and sedimentation in rivers and other aquatic areas.
Answer:
The best answer to the question: Which process is the best interpretation of this scenario, would be: C) Microevolution.
Explanation:
Microevolution is defined as the changes in allele expression and frequency within a specific population and which take place within a relatively short period of time regarding evolution. There are different reasons why microevolution might take place, instead of genetic evolution at a much larger scale, and throughout a much larger period of time, which would be typical of macroevolution. These reasons are: mutations, natural and artificial selection, gene flow and genetic drift. In the case of the bird found in Galapagos by Peter and B. Rosemary Grant in 2002, the differences in the finches arose due to natural selection when confronted with a change in their climatic conditions, and therefore, the availability of food. These changes in the environment drove the birds with larger beaks to be first privileged in food acquisition and also in reproduction, making their genetic make-up more prevalent, while those with smaller beaks, due to shortage of food availability, became incapable of passing on their genes to future generations. Natural selection played its role and one set of genes expressed themselves more frequently due to the circumstances and the reproductive process. But when things changed, the situation reversed. This is all characteristic, given the small changes and the reversion, of microevolution, or evolution at a small scale.
