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.

Osteoblasts move in and ossify the matrix to form bone. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness or diameter throughout life. The increase in diameter is called appositional growth.

An example of a consumer in a pond ecosystem is...

A. a water lily

B. algae

C. a reed

D. a frog

Answers

In a pond ecosystem, the primary consumers are tadpole larvae of frogs, fishes and other aquatic animals which consume green plants and algae as their food. These herbivorous aquatic animals are the food of secondary consumers. Frogs, big fishes, water snakes, crabs are secondary consumers.

In a pond ecosystem, the frog serves as a consumer. The correct option is D.

What is a consumer?

Consumers are lifeforms that require food to produce energy. These organisms are known as heterotrophs, which means they must consume something else as food.

In a pond ecosystem, tadpole larvae of frogs, fishes, and other underwater animal life that eat green plants and algae are the primary consumers.

Thus, the correct option is D.

how is a trait passed down from parents to offspring USE OWN WORDS

Answers

A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. If gene pair contains a dominant allele, the the offspring will show this dominant trait

In North America, the eastern spotted skunk mates
in late winter, and the western spotted skunk mates
in late summer. Even though their geographic
ranges overlap, the species do not mate with each
other. What most likely prevents these two species
from interbreeding?
A. habitat isolation
B. gametic isolation
C. geographic isolation
D. reproductive isolation

Answers

The answer is gonna be B

Reproductive isolation is a mechanism through which species do not get to interbreed. Option D. reproductive isolation

What is reproductive isolation?

This is a mechanism through which different species or populations do get to mate and produce fertile offspring. This mechanism allows the accumulation of genetic differences and favors speciation.

There are different barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers prevent mating between two or more species. There are two types of barriers,

prezygotic ⇒ that avoids fertilization between individuals of different species, postzygotic ⇒ that impedes the zygote to develope and reach the adult stage.

Pre-copulatory o pre-ziygotic:

• Ecological or by habitat isolation;

Seasonal or temporal;

• Séxual o ethologic;

• Mechanic;

• Gametes incompatibility.

Postzygotic mechanisms or barriers include

• Hybrid inviability,

• Hybrid sterility,

• Cytoplasmic interactions.

In the exposed example occurs a seasonal difference between the mating period of the eastern spotted skunk and the western spotted skunk.

Probably, if both of them would mate during the same season and in the same area, they could reproduce.

However, since their mating season differs, individuals from each species do not get to cross and hence, produce fertile offspring.

Option D. reproductive isolation is what most likely prevents these two species from interbreeding
