How does geographic isolation contribute to evolution?

2 answers:

7 0

Geographic isolation of a group of organisms eventually stops gene flow from other groups of same species. Thus isolated group evolves by accumulating new mutations not to be found in members of related groups.

Geographic isolation contribute to evolution in many ways. First it stops gene flow between different sub populations. Mating can only happen in this specific gene pool. Second new mutation may appear and act as an unique identity of the gene pool. Eventually the sub population would become very different from the original group. Thus, this prevents them from mating with the original group again.

There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.

<h3>Features associated with each of Earth's four spheres.</h3>

<h3>Hydrosphere </h3>

It is the set of all the water on the planet, including those that form clouds.

<h3>Lithosphere</h3>

The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.

<h3>Atmosphere</h3>

It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.

<h3>Biosphere </h3>

It is the part of our planet that can support life

<h3>Internal processes</h3>

The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.

With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.

Roundworms are pseudocoelomic. This means that they have A. organs, but no true body cavity. B. a true body cavity, but no organ

Naily [24]

Answer: The correct answer is-

A. organs, but no true body cavity.

Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).

Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.

Body cavity is present between the external wall of body and the intestine and it baths the different body organs.

Thus, option A) is the right answer.
