Answer:
The answer is B
Explanation:
Tree rings form because during each growth season new water and food conducting cells (tracheids) are added around the perimeter of the tree trunk. Cells in the spring growth tend to be larger with thinner walls than the previous set of cells produced at the end of the previous summer. Over the course of the growing season, successive rings of cells become smaller with increasingly thick walls. In winter, growth ceases and no new cells are laid down. Then when the new growing season begins, thin-walled large cells form again producing a clear line between the old wood and the new wood because of the difference in texture.
Tree rings provide a record of past climate because their width is determined by tree growth rate, which in turn is determined by environmental conditions. Since one ring is produced every year (usually) the ages of the climatic events can be worked out very precisely by counting back. Records from young trees, old trees, house and ship timbers and fossil trees can be tied together by identifying sections with the same sequence of climatic event, the records overlap in time where the climatic patterns they record match up.
Answer:
Two nuclei form into one nuclei.
Explanation:
Nuclear fusion is a type of reaction in which two atomic nuclei are combined to form one atomic nuclei and subatomic particles i.e. neutrons or protons with the release of energy. In nuclear fusion reaction, some amount of reactant transform into a new atom because the mass of reactant is higher than the single atom while the remaining amount of reactant transform into energy. This reaction occurs in the sun which provides energy to the whole universe.

Answer:
Scholars knew that the Egyptians believed in afterlife, because, first, after the discovery of the Rosetta stone, they were able to read many ancient scripts that mentioned procedures to ensure that one goes to the afterlife.
