<span>Most organisms, including humans, can't use the free gaseous form of nitrogen found in the air. We need other organisms and natural processes to "fix" nitrogen into a solid form that plants and animals can use. Most of the nitrogen that plants and animals use is made by bacteria.</span>
Cells get energy for their functioning through sunlight and other organic food molecules. ATP is a good example of energy pathways through photosynthesis.
The goal was to see if Earth's ecosystems could be successfully manufactured and maintained elsewhere in the galaxy, should we need to bail on this planet.

Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
When chiasmata can first be seen in cells using a microscope, the following processes has most likely occurred in prophase I.
<h3>When chiasmata can first be seen in cells using a microscope?</h3>
Recombination can occur at any two chromatids within this tetrad structure.
Crossovers between homologous chromatids can be visualized in structures known as chiasmata, which appear late in prophase I.
Thus, option "C" is correct, Prophase I.
