The malignant disorder of mature antibody-secreting b lymphocytes or plasma cells is called the Multiple Myeloma. Multiple Myeloma is a cancer of plasma cells in the bone marrow. The condition features abnormal proliferation of plasma cells in the bone marrow, destructive bone lesions, and the production of abnormal proteins, specifically antibodies. Its symptoms may include, fatigue, bone pain, bone fracture, kidney failure among other symptoms.
The correct answer is descent from a common ancestor.
Homologous structures are the structure which is similar in appearance but perform different functions in a different organism.
The wing of a bat, leg of an alligator and arm of a human, they all look similar in appearance with same type and number of bones but they all perform different functions in them.
The same type and number of bones show that they all have come from the same structure of the last common ancestor or their ancestor was common. This type of evolution is called divergence evolution and provides a piece of evidence to the theory of evolution given by Charles Darwin that "all species arises from same ancient common ancestor also called descent from a common ancestor". This proves that the evolutionary history of life forms a branching tree.
Thus, descent from a common ancestor is the correct answer.
Aspirin is a weak acid with a Pka of 3.5. With this Pka of 3.5, it is in a neutral or what is known as protonated form at a pH below 2.5. At higher levels of pH, it becomes increasingly protonated or anionic, therefore, it is better absorbed in more acidic environment of the stomach. This is because absorption requires passage through the plasma membrane, the rate which is determined by the polarity of the molecule. Charged and highly polar molecules pass, slowly, while the neutral hydrophobic ones pass rapidly.
When the chipmunk cells use the plant sugars to obtain energy in order to carry out the cell processes, the chemical energy present in the sugars is getting converted into the kinetic energy. The plant sugars are broken down into its components in order to release the stored energy (potential energy). When released, this energy helps in carrying out various functions, such as respiration, digestion, etc (kinetic).
Hence, the answer is 'Option A - chemical energy -> kinetic energy'.
