Evolution is the change in heritable traits of biological populations over successive generations.
What is evolution of life?
- Evolution has produced the variety of life that exists on Earth today. Since life first emerged on Earth between 3.5 and 4 billion years ago, it has continued to develop.
- At initially, there were just single-celled, primitive species on Earth.
- The first multicellular organisms appeared much later, and as a result, the diversity of life on Earth significantly increased.
- Darwin put out a substantial amount of evidence to back up his idea of evolution by natural selection.
- Evolution is the gradual alteration of a living thing's traits over time. Natural selection is the process of evolution.
- Through their DNA, organisms transmit their traits from one generation to the next.

Answer;
-The first antibody is specific for the primary amino acid sequence of TT, whereas the second is specific for conformational determinants.
Explanation;
-Antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction.The specificity of the binding is due to specific chemical constitution of each antibody.
-The amino acid sequence in the tips of the "Y" varies greatly among different antibodies. This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen. The variable region includes the ends of the light and heavy chains.
Autografts are skin grafts from the own patient, so the skin will not be recognized as a foreign substance, and there is no chance that the body will reject the cells.
