natural selection and common descent are the 2 ideas Darwin used to explain evolution
As you can see in the picture presented below, the three classes of water have distinctive traits.
Pure substances contain only one element, they are not mixtures of different things.
The homogeneous mixtures have multiple elements, but they are so well blended together that you can't easily observe or separate them.
In heterogeneous mixtures, we can easily differentiate between different elements of the mixture.
Answer:
<em>The mushroom in the picture and the option choices are included in the attached image. below...</em>
The highlighted region of the mushroom in the picture represents the mushroom's <em>"Gills"</em>, and paticularlly the multicellular structure carrying the <em>Hymenium</em> called <em>"the basidiocarp"</em> aka basidioma; the Hymenium or underside of the mushrooms is comprised of vertical plates arranged radially, and if a cross section of this is exposed by making a straight cut through the basidiocarp on a microscope, it would appear as option: (A.

In the process of the nitrogen cycle. <span>
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA. </span><span> </span>
