Answer:In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
Explanation:
Answer:
The Rhizaria are supergroup species of mostly unicellular eukaryotes and classified as protista. Rhizaria include species like cercozoa, foraminifera and radiolaria.
<u>Some of the attributes of Rhizaria are:</u>
- non-photosynthethic in nature, but some have a symbiotic relationship with unicellular algae.
- express only rDNA sequences so they can vary in different forms.
- do not have clear morphological characters
- they mostly includes amoebas which functions for food engulfing and help to direct movement in rhizarian protista.
<u>Contribution of Rhizaria to the ecosystem:</u>
- There are known as abundant bacterial grazers, and play very important role in microbial food webs.
- They provide a wide diversity of marine organisms.
- important contributors to oceanic carbon pools .
Hence, Rhizaria are important part of ecosystem.
Its important because they produce offspring. Without any offspring the species would slowly die off and become extinct.
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
