Answer:
Unequal.
Explanation:
The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.
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.
It needs to contain a nucleus and cell membrane or cell wall and golgi bodies and mitochondria
