<h3>What are
cells?</h3>
- Cells are the basic building blocks of all living things. The human body is comprised of trillions of cells. They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions.
- Cells are of two types: eukaryotic, which include a nucleus, and prokaryotic cells, which do not have a nucleus, but a nucleoid province is still present. Prokaryotes are single-celled organisms, while eukaryotes may be either single-celled or multicellular.
- They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions. Cells also include the body's genetic material and can make duplicates of themselves. Cells have multiple parts, each with a separate function.

Explanation: u can find the answer there
Each ring marks an entire cycle of seasons, or one year, within the tree's life. Hence 23 rings shows 23 years of trees life . Measurement of tree rings are based on Radiocarbon dating. These rings can tell us how old the tree is, and what the weather was like during each year of the tree's life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.
Rings of trees growing in temperate climates can indeed tell their age through their annual rings and also help determine the age of wood used to construct buildings or wooden objects.
