Answer:
A
Explanation:
The correct answer here would be that less than 3 percent of Earth's water is freshwater containing no salt.
Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms.
The correct option is A.
Which is more important: species richness or species evenness?
Answer:
Honestly i think that its Richness because its good to have a good amount of different species so that there is a good number of animals to create a food chain. The amount of animals in a population is important but its more important to have a variety of different animals so that all the populations have other animals to eat or survive off of.

Which is one piece of evidence of seafloor spreading?
fossil material
continent material
drilled core samples
ocean water samples
One of the evidence of seafloor spreading is continent material.
Seafloor spreading can be regarded as geologic process which involves the splitting apart of tectonic plates.
This plates serves as large slabs of Earth's lithosphere and this spreading as well as some activities is been done by mantle convection.
One of the evidence of this spreading is continent material which could be any Continental mass that can rise.
We can conclude that one of evidence of seafloor spreading is
continent material.

The following are the correct matches:
Old rivers-Have many meandersYoung rivers-Carry large objectsMature rivers-Carry medium-sized objectsWhat are rivers?Rivers are bodies of flowing water that are typically found on the surface of the Earth. They are formed by the accumulation of precipitation, such as rain or snow, in a specific area and flow in a defined channel towards an ocean, a lake, or another river. Rivers can vary greatly in size and length, with some being just a few meters wide and a few kilometers long, while others can be several kilometers wide and thousands of kilometers long.
They are an important resource for humans and other living organisms, providing water for irrigation, drinking, and industrial uses, as well as serving as habitats for a wide variety of plant and animal life. Rivers also shape the land they flow through, eroding and depositing sediment, and creating features such as valleys, deltas and canyons.

how can you use the electron configuration to determine the number of valence electrons
Here, we are required to explain how the electronic configuration can be used to determine the number of Valence electrons.
The algebraic sum of electrons in the highest energy level in an electron configuration is the number of Valence electrons of the element.Valence electrons simply refers to electrons present in the outermost shell of an element.
Valence electrons simply refers to electrons present in the outermost shell of an element.The electron configuration is a representation of the arrangement of electrons in the atomic orbitals of an element.
The number of electrons present in the outermost shell as evident from the electron configuration can be used to determine the Valence electron in the elements.Fir instance: the electron configuration of potassium; 1s² 2s² 2p⁶ 3s² 3p⁵
The algebraic sum of electrons in the energy level 3 therefore is the number of Valence electrons.

Where are electrons found in Atoms
Answer:
Explanation:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.
