The sun is a vital part of the earth, so if it changes energy levels, it will clearly have an affect on the earth. If the energy increases, it'll most likely dry out the grass and melt the snow, etc. If it decreases, the snow could freeze and change the climate.
Answer:
The correct answers are -
A. Find the absolute age of rocks at both locations.
B. Compare a layer at one location to layers at other locations
C. Identify index fossils in one or more layer at one location.
Explanation:
A scientist who studied the earth and different aspects such as it's structure and the materials it made if up known as a geologist. Classifying rocks and discovering various components and matter on earth are the major duties of a geologist.
At some point, rocks can be located at a distance beyond the reach of geologists. Nevertheless, they have a way of studying, and comparing the layers of those rocks helps them to understand the basic difference in the earth locations and the presence of certain components of earth.
Comparing rocks and layers can include these steps at first by geologists-
A. Find the absolute age of rocks at both locations.
B. Compare a layer at one location to layers at other locations
C. Identify index fossils in one or more layer at one location.

The mechanism of somatic recombination known as V(D)J recombination only takes place in developing lymphocytes at the beginning of T and B cell maturation. As a result, B cells and T cells, respectively, have a very varied repertoire of antibodies/immunoglobulins and T cell receptors (TCRs).
<h3>What are immunoglobulin genes ?</h3>
Only B cells can make immunoglobulins, which are encoded by the immunoglobulin genes. The two identical heavy chains that make up immunoglobulin molecules are coupled with the two identical light chains, kappa and lambda. There are numerous chromosomal locations where the immunoglobulin genes are found.
- B-cell immunoglobulin gene rearrangement tests are used to help diagnose non-Hodgkin B-cell lymphomas and evaluate for residual or recurrent disease after treatment. There are many different types of B-cell lymphoma and each has different characteristics, prognoses, and a likely response to therapy
