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

Answers

Answer 1

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.

Explanation:

The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve ​

Answers

Answer:

Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).

The first serve of each side-out is made from the right-hand court.

If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.

As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.

When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).

The second server continues serving until his team commits a fault and loses the serve to the opposing team.

Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.

In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.

The correct option is A.

group of populations that have shared a past and will have a shared future

Answers

Answer:

La reproducción sexual consisten en la unión de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los gametos son células especializadas que se forman por un proceso meiótico y tienen en su núcleo la mitad de la información genética de un organismo, por lo que reciben el nombre de células haploides de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la variación genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son diferentes a ellos. El proceso en el que se une las células sexuales se le conoce como fecundación. En los animales esta pude ser interna o externa.

Explanation:

Los gametos (óvulos y espermatozoides) son células germinales especializadas que se desarrollan a partir de un proceso llamado gametogénesis (espermatogénesis en machos y ovogénesis en hembras). El proceso de gametogénesis implica un tipo de división celular llamado 'meiosis' donde la cantidad de cromosomas se reduce a la mitad. En humanos, el número cromosómico diploide (2n) de 46 cromosomas se reduce a un número haploide (n) de 23 cromosomas. La fecundación es el proceso por el cual los gametos se fusionan durante la reproducción sexual para producir un cigoto diploide. En la reproducción sexual, el aumento de la variación genética en la progenie es un resultado de tres procesos diferentes: la unión aleatoria entre gametos durante la fecundación, la distribución independiente de los cromosomas durante la gametogénesis y el entrecruzamiento (recombinación o crossing over) entre cromátidas de cromosomas homólogos durante la meiosis. Finalmente, en animales, la fecundación puede ser interna, la cual se produce mediante la unión de los gametos dentro del cuerpo de la hembra (por ejemplo, gallina, leona, cebra, etc.), o fecundación externa, donde la fusión de gametos se produce en el ambiente externo (por ejemplo en peces, sapos, ranas, etc.).

5. Consider a system consisting of an egg in an incubator. The white and yolk of the egg contain proteins, carbohydrates, and lipids. If fertilized, the egg is transformed from a single cell to a complex organism. Discuss this irreversible process in terms of the entropy changes in the system, surroundings, and universe. Be sure that you first clearly define the system and surroundings.

Answers

Answer:

According to the question, we could consider the developing chick as the system and the surrounding of this system would be nutrients, external environment, or world and eggshell that affects the system. The entropy of the system decreases with the transformation of the development of the cell into a chick drastically.

In this system initially, it has a low entropy condition as it the surrounding have complex fuel molecule compare to the system, however, during the period of incubation the complex molecule of surrounding fuel release in the high quantity of CO2 and water molecules and leads to the higher entropy of surrounding than the decrease in the entropy of the system.

*Earth Science* Active continental margins where the plate boundary is ocean-continent convergent are characterized by accretionary wedges.
True or false?

Answers

The correct answer is True

Explanation

An accretion wedge is an area where deformed sediment accumulates that occurs at a convergent edge at the boundaries of subduction plates (ocean-continent). This process occurs when sediments from the oceanic crust accumulate to the block of continental crust produced. by the subduction movement of the oceanic crust. So, the correct answer is True.
