Inner core  was found to be solid after observing the motion of P waves.

Explanation:

Seismologist Inge Lehmann, studied the seismic waves of an earthquake and discovered about inner core in the mantle layer of Earth. She States that there is a boundary of discontinuity between the outer and inner core of Earth.

She studied the travel of secondary and primary waves during an earthquake and how it flows at different shells of Earth's layer which helped her in finding about the inner core of mantle. She observed that the inner core is a solid layer inside the molten layer of outer core

Study these diagrams. The dots represent valence electrons orbiting the nucleus of an atom. Which diagram shows the valence elec
steposvetlana [31]
In the picture attached to this question, the two diagrams above did not show very well but I believe that the first diagram contain four dots, which means that the correct option is A.
Carbon has six electrons, that is why 6 is its atomic number is 6 . In writing electronic configuration, two electrons are usually placed in the most inner shell while the other shells will have 8 electrons each. In the case of carbon which has 6 electrons, only four will remain after 2 electron has been put in its inner shell. Therefore the number of electron in its outermost shell will be four.

bazaltina [42]

Answer:

a move from the fundamental niche to the realized niche for both species.

Explanation:

The niche of an organism is the functional role of the organism in the community or the ecosystem as a whole. This include the environment an organism lives and all the jobs it does in it.

Fundamental niche refers to all the possible functional roles of an organism in an ecosystem while realized niche refers to the specific roles the organism is limited to as a result of resource limitation, competition or other factors.

Resource partitioning involves the division of limited resources among organisms so as to avoid competition within the niche.

<em>Hence, resource partitioning causes a move from the fundamental niche of an organism to the realized  niche of that organism. </em>
