Which of the following is characteristic of antibodies? Group of answer choices composed of heavy and light polypeptide chains three binding sites per antibody monomer incapable of being transferred from one person to another carbohydrate structure

Composed of heavy and light polypeptide chains.

Explanation:

Antibodies are generated by the immune system mostly by the plasma cells in acknowledgment of the existence of any foreign substance, known as an antigen via the fragment antigen-binding (Fab) variable region.

Antibodies are Y-shaped in a structure that contains 4 polypeptides 2 heavy chains and 2 light chains. This structure of antibody helps to reach their dual functions one is antigen binding and another is biological activity mediation.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
