This is referred to as the critical concentration, it is the exact concentration of the subunits that allows for equal growth and degradation of the filament.
Covalent compounds are formed from nonmetals while ionic compounds are formed from nonmetals and metals (Specifically, a metal transfers electrons to a non-metal).
Answer:
Spanish: La evolución es el proceso por el cual los organismos actuales se han descendido a partir de antepasados antiguos. ... La variabilidad genética es una parte fundamental del proceso, ya que la evolución se produce cuando fuerzas selectivas actúan sobre esa variabilidad.
English: Evolution is the process by which current organisms have been descended from ancient ancestors. ... Genetic variability is a fundamental part of the process, since evolution occurs when selective forces act on that variability.
Explanation:
Conjugation is the process name !
An atom is the smallest known unit and it is present in all the matter. The space occupied by atom is divided into two components: the nucleus and orbitals. The nucleus is the center of the atom, and orbitals surround the nucleus.
Location of protons-
Protons are positively charged particles within atoms. Each atom has at least one proton. The number of protons determine the identity of an atom.Protons reside in the nucleus of the atom.
Location of Electron-
Electrons travel around the nucleus in the orbital. Electrons are negatively charged particles. In a neutral atom, the number of electrons and protons are same. Though they are much smaller than protons but have the same strength charge.
Location of Neutrons-
Neutrons are located with protons in the nucleus. They have no charge and have the same mass as protons. Not all atoms have neutrons, and the number of neutrons is not usually the same as protons or electrons.
Part B-
I agree with Jane's statement as an aluminium atom has a dense central nucleus surrounded by negatively charged electrons, The protons and neutrons are closely packed in the center an 13 electrons are surrounding this center.
