Explanation:

why groups of animals are found on some islands but not others?

Answers

Answer:

Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.

Explanation:

A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.

The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.

Draw the structures of deoxyribose, guanine, and phosphate and rate their relative solubilities in water (most soluble to least soluble). How are these solubilities consistent with the three-dimensional structure of double-stranded DNA?

Answers

Answer:

The solubilities in water of the three molecules from most to least soluble is in the following order: phosphate > deoxyribose > guanine.

Explanation:

The phosphate group is the most water-soluble due to it being very much negatively charged .

The deoxyribose which has several hydroxyl groups, is the next most water-soluble molecule.

The guanine molecule is hydrophobic, therefore, it is the least soluble in water.

A DNA molecule is composed of the three molecules: deoxyribose sugar, a phosphate group and a nitrogenous base which could either be a purine or a pyrimidine.

The three dimensional structure of DNA is such that the the phosphate groups and deodyribose sugars form the backbone of the structure on the outside of the DNA double helix where they are exposed to the aqueous environment of the nucleus. On the other hand, the hydrophobic nitrogeneous bases are located in the interior of the double helix where they are excluded from excludedthe aqueous environment of the nuclues. This structural arrangement is in accordance with the solubility of the molecules where the water-soluble phosphates and sugars are exposed to water while the water-insoluble bases are away from water.

Explanation:

The following statements concerning the karyotype in the diagram is true - The diagram illustrates the results of nondisjunction during gamete formation.

Karyotype

Karyotype refers to the number and appearance of chromosomes present within the nucleus of a eukaryotic cell. It is illustrated as a diagram such as given in the question.

There is no Down's syndrome as the karyotype demonstrates a normal pair of chromosome 21.  In this karyotype, there is an extra X-chromosome that depicts non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents leading to the 23rd trisomy.

Answer:

Describe the two eukaryotic animal organelles that have roles similar to the organs of the human digestive system

→Two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system are lysosome and mitochondria.

Describe how proteins are made packaged and transported within the cell

→Vesicles transport the proteins from the ribosomes to the Golgi apparatus, a.k.a Golgi complex, where they are packaged into new vesicles. The vesicles migrate to the membrane and release their protein to the outside of the cell. Lysosomes digest and recycle the waste materials for reuse by the cell.

Which natural resource is renewable?
A. coal
B. wind
C. topsoil
D. oil

Answers

Wind because you can always get it make with photosynthesis

Wind is the natural resource which is renewable. Therefore, option (B) is correct.

Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.

Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.
