Anaphase 1!! Metaphase is when the chromosomes move near the equator (middle) think about it was “M” for metaphase and “M” for middle! This happens in both metaphases!
let's take a look at the definitions and see wich best maches with what she is looking for.
geology: the science that deals with the earth's physical structure and substance, its history, and the processes that act on it.
zoology: the scientific study of the behavior, structure, physiology, classification, and distribution of animals.
botany: the scientific study of plants, including their physiology, structure, genetics, ecology, distribution, classification, and economic importance.
meteorology: the branch of science concerned with the processes and phenomena of the atmosphere, especially as a means of forecasting the weather.
*the climate and weather of a region.
hopes this leeds you in the correct direction.
Equilibrium.
diffusion occurs due to differences in concentration of substances in different regions. then substances will naturally spread out (due to innate Brownian kinetic energy). the spreading I. e. diffusion will stop until equilibrium is achieved.
note: those substance particles are still moving due to the innate Brownian kinetic energies!
The answer is; producing a unique antibody from all other B cells by genomic rearrangement.
An isolated B cell produces monoclonal antibodies (also called Immunoglobulins). Different B cell types produce different types of antibodies (hence the serum of an animal has polyclonal antibodies). Memory B cells are developed when a particular infection is eradicated by the immune system. These B cells proliferate when the infection returns by producing the same antibodies that were effective against the foreign entity.
