Answer:

separation of populations has led to the evolution of new species

Explanation:

When the populations evolve to become distinct species, then this process is termed as speciation.
Speciation can occur due to various reasons and one of these reasons is geographic isolation that leads to separation fo the populations which then faces different evolutionary pressure and thus evolve into new species.
In the Hawaiin islands, there are different species of honeycreepers because of the unique geology of Hawaii due to which new volcanic islands are constantly being formed and eroded which leads to the separation of population and their evolution into new species.

Explain how salinity and temperature affect water density and how the salinity of the oceans can be both increased and decreased

finlep [7]

Answer:

Salinity is the salt concentration in water. Oceans salinity and temperature affect density of water, Higher the salinity denser the water and Lower the temperature denser the water.

Explanation:

As we go down in the ocean , temperature goes down and denser the water.

Less dense water will be on top and higher the density will be on bottom. Warmer water will be on top.

Salinity increased in ocean on evaporation of sea water and formation of ice in water. Weathering of rocks , formation of soil also add minerals and salt in ocean.

Melting of snow, ice in sea, addition of river freshwater and precipitation of rain decrease the salinity of ocean.

Answer:

Chitin

Explanation:

This glucose derivative is in fact the main building block of cell walls in not only arthropods (including the shrimp), but also fungi and insects, and also has a structural function in the scales of fish. The most similar commonly-known substance in terms of function is keratin, which makes up our hair and nails.

According to the theory of plate tectonics, which is one feature that plates carry?

Phoenix [80]

Answer:

seafloor

Explanation:

A plate, often described as a lithospheric plate, with seafloor, continents and mountains on top of it.
The earth is divided into three layers based on their chemical composition. Undoubtedly, there is a component called the lithosphere.
The lithosphere consists of a crust and a portion of a solid upper mantle.
Below the lithosphere is the asthenosphere.
There are two types of crusts: the continental crust and the oceanic crust.
Where there is a seabed there is a sea crust.
Mountains are also found in oceanic and continental crusts.
The intercontinental layer corresponds to the continents.
