Athick tree ring indicates which of the following

The correct answer is option A, that is, the year was good for growth.

In the regions where the length of the growing season is the restricting element, the thickness of the rings of the tree can suggest that when the growing time was lengthier (at the time of warmer times) and when the growing seasons were shorter (cooler times). The study of the development of the rings of the tree is called dendrochronology.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
