Explain what would happen if conditions changed that causes the seaweed to die. now striped fish stand out to predators more than solid fish. how could natural selection result in a change to relative numbers of solid and striped fish? what important concept does this illustrate about the connection between natural selection and the environment?

Natural selection would cause the number of striped fish to decrease while the number of solid fish to increase or remain the same. This shows the concept that the environment is what forces natural selection to occur.

We can arrive at this answer because:

This all shows how the environment is the main trigger for natural selection.

To answer this question it is necessary to visualize the image that is attached.

An organism change itself in response to the surrounding environmental condition.

Explanation:

Since striped fishes are able to save themselves from the predators due to their natural ability , the solid fishes would be an easy prey to the predators. This would lead to reduction in the number of solid fishes. Also the sea weed started dying because of environmental change. Thus, predators would shift their feeding pattern from sea weed to easily identifiable fish that is the solid fish and hence the solid fish may deplete rapidly.

Also the striped fishes in later stages may undergo natural selection to prevent themselves from the predators.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

the answer would be..
