Prokaryotic cells are cells that do not have a true nucleus or most other cell organelles.
Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane.
<span>When we are talking about biogeochemical cycles we are talking about the pathways by which a chemical substance moves through both the biosphere and the atmosphere. There are a number of cycles which come back to the starting point and which can be repeated. Moreover, the very term biogeochemical tells us that there are more than one factor involved. We have chemical, biological and geological factors at play. The circulation of chemical nutrients through the biological and physical world are known as biogeochemical cycles.</span>

A Scientist would consider the color and the width of tree rings give clues about the past climatic conditions of a place.
<u>Explanation:</u>
Trees are quite sensitive to local climatic conditions like rain, temperature, etc. That is why they tend to be useful for weather experts to judge the climate variations. There are many clues seen in the rings of the trees that are helpful in studying the local climate.
Some of the clues are obtained by
- Seeing the patterns and width of the rings
- Seeing the density and composition of the rings
- Smelling the odor of the wood.
- Location
The concentric rings tell about the age of the tree and the weather conditions during its life period. The light - colored rings tells that the tree has grown in the spring and early summer season whereas the dark rings tell that the tree has grown in late summer and during fall.
Moreover, the rings get wider in warm, wet years and get thinner in cold and dry seasons. If the tree has experienced harsh conditions like drought, etc., it will have a hindered growth.
Proteasomes are a large protein complex present in all eukaryotic cells that break down protein.
<h3>What are proteasomes?</h3>
It is considered one of the main pathways involved in the processes of enzymatic protein degradation.
It is the group of proteins that are associated forming large complexes, whose function is to digest cytoplasmic proteins, generating peptides.
Therefore, we can conclude that proteasomes is a large protein complex present in all eukaryotic cells that breaks down protein .
