Biology

-BARSIC- [3]3 years ago
7 0

Answer and Explanation:

Easter Island, a small island of around 64 square miles, has been a mystery for many scientists who study the changes on the past and current biodiversity abundance. According to research, this island used to be extremely diverse in species of fauna and flora, especially the latter. However, it is now composed of few species of invertebrates and little to almost no vegetation. This occured <u>due to the first colonizers</u> who rapidly deforested the region.

Research suggests that, apart from this deforestation, which caused the decline of wildlife species that depended on shrubs and palm trees, Polynesian colonisers introduced the Polynesian rat, which consumed almost all of the trees that were present in the island, leading to the absence of their regeneration.

The given scenario illustrates  An emergent property.

<u>Explanation:</u>

A property that explains about the functioning of any system as a whole is an emergent property. The units of that individual system will not work to give the functionality of the entire system. Fallacy of division occurs when there is a failure in the realization of this emergent property.

For instance let us take an ant colony. Ant as a single organism will not be able to attain certain works. While when they join to form a colony they together can accomplish complex and tedious tasks. Hence, in human body also cells of heart acts as an example of an emergent property as they together can accomplish the function.

Hox genes are sometimes called "master switches". They have acquired this nickname because a single Hox gene will turn on (or of
Gwar [14]

Answer: B. False

Explanation:

“Hox” genes are a highly conserved group of genes, all of whose products are transcription factors bearing a specific domain (called a ”homeodomain”). The transcriptional activity of a large amount of genes relevant to embryonic development is controlled by regulatory sites which are able to bind to this domain. Changes in the transcriptional activity of even a single Hox gene may thus have dramatic downstream effects on the phenotype, as this will result in several further genes having their transcription either enhanced or suppressed.

Which best describes Darwin's studies that led to the theory of evolution?
ddd [48]

Answer:

The answer is B, extensive research of an individual organism over many years.

Explanation:

The question is asking, what best describes Darwin's studies that led to the theory of evolution, it would be a lot of research over a long period of time. Think, if you were to do a school project, would you get your best results over a short or long period of time with little or a lot of evidence/research? So, B is the best answer, I believe.
