<span>The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell</span>
Answer:
Photons
Explanation:
Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.
The Heart is located in the Thoracic Cavity medial to the lungs and posterior to the sternum.
<span>This is a positive feedback. These episodes make the next glacial period even more severe and long-lasting than the one prior. This is due to the reflectance of the surface of the land having a positive relationship with how much energy is absorbed: as the reflectance increases, absorption decreases, and the glacial period increases in severity.</span>
