The question refers to the following description.On the Bahamian island of Andros, mosquitofish populations live in various, now

-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences.Which two of the following have operated to increase divergence between mosquitofish populations on Andros?1. improved gene flow2. bottleneck effect3. sexual selection4. founder effect5. natural selectionA. 3 and 4B. 2 and 4C. 2 and 3D. 1 and 3E. 3 and 5

Answer:

Sexual selection and natural selection

Explanation:

The mosquitofish population living in ponds with predators swim in fast bursts to protect themselves from the predators. The other population of mosquitofish living in a pond with a few predators swims continuously. This is an example of natural selection. The mosquitofish that can swim in fast bursts are favored in predator rich ponds due to their survival success over the ones that swim continuously.

Breeding preferences as exhibited by females of the two populations of mosquitofish represent the sexual selection. These females prefer the mate according to some advantageous features.

Explain e.o. wilson’s theory of island biogeography as it applies to environments other than islands physically surrounded by wa
laiz [17]

Today, any environment surrounded by other ecosystems that are unlike it is subject to Wilson’s theory of island biogeography. Because they are geographically isolated from other related ecosystems, these ecologies are referred to as "islands." Waterbodies divide tropical islands, but this idea also takes into account mountaintops, caverns, and other isolated ecosystems.

<h3>What is Wilson’s theory of island biogeography?</h3>
  • The biologist Edward O. Wilson and environmentalist Robert MacArthur published The Theory of Island Biogeography in 1967. It is widely considered as a foundational work in the ecology and biogeography of islands. The book was reissued by the Princeton University Press in 2001 as a volume in their "Princeton Landmarks in Biology" series.
  • The hypothesis that insular biota maintain a dynamic equilibrium between extinction and immigration rates was made more well-known by the book. An island's pace of new species immigration will decline as the number of species increases, while the rate of extinction of native species will rise.
  • Thus, MacArthur and Wilson anticipate that there will come a point of equilibrium where the rate of immigration and the rate of extinction are equal.

Answer:

Sugars and phosphates  

Explanation:

DNA is deoxyribonucleic acid.

The backbone is based on a repeated pattern of a sugar group (deoxyribose) and a phosphate group.  

The image below shows one straightened-out strand of DNA with a backbone of alternating sugars and phosphates.

A is wrong. There is no ribose in DNA.

B is wrong. The nucleic acids A, C, G, and T join one strand of DNA to the other.

C is wrong. There is no RNA in DNA.
