In energy processing systems electronic carrier molecules transfer electrons from one part to other part of energy processing system. This provides the necessary energy and reduces power to carry out chemical reactions. They are necessary for aerobic cellular respiration and photosynthesis.
When pigments are mixed together, more colors are being absorbed which results to few colors that will be reflected. Each pigment absorbs and reflects light which results to the "color" or hue that we see. When these pigments are to be mixed, then more wavelengths would be absorbed which results to lesser reflection.
In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer onesI just learned about this in our rocks and minerals unit for science,
2. C (2, 1, 4, 3)
3. A (Determine the volume by how much water it displaces, then divide mass by volume)
4. H (Water all the containers the same amount and at the same time)
5. A (1.7 mL)
Fossils only form if certain qualifications are met, and some organisms cannot meet them, so they just cease to exist, not a single sign of them. This could happen if they were organisms that decayed completely. Fossilization can include freezing, drying, and encasement, usually in tar or resin.
