Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
Answer:
The correct answer is option c. "frameshift mutations".
Explanation:
The reading frame of a gene is based on base-pair triplets, starting from the start codon until the ribosome encounters with the end codon. Base-pair additions and deletions are collectively referred to as frameshift mutations because they alter the reading frame of the gene. Base-pair additions and deletions break down the original sequence of the gene triplets, which alters the open reading frame and usually results in the production of non active proteins.
Answer:
It means that it is trying to increase it's infectivity rate and its survivability rate in different environments.
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.Research carried out with the use of these cells has demonstrated their effectiveness in the treatment of various diseases, such as leukemia, heart disease and hematological diseases. Embryonic stem cells, in turn, have the ability to form any tissue in the body.
<h3>How are embryonic stem cells used?</h3>
Stem cells have the ability to differentiate and self-renew. For this reason, they can be used in the treatment of degenerative diseases. Stem cells stand out for their ability to transform into different cell types, that is, they are cells with a great capacity for differentiation.
<h3>What diseases could be treated with the use of Embryonic Stem Cells?</h3>
- Diseases that can be treated with stem cells
- leukemias. Leukemia is a generic term used to describe the “cancer” of leukocytes, the white blood cells.
- Thalassemias.
- Neuroblastoma.
- Primary immunodeficiencies.
- Sideroblastic anemia.
- Metabolic diseases.
- Sickle cell anemia.
With this information, we can conclude that Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.
