Because bryophytes do not have a vascular tissue they
D) grow close to the ground
<span>Scientists found that the cytoplasm of cells undergoing mitosis, if injected into cells at other stages of the cell cycle, could induce the non-dividing cells to start mitosis. This suggested that a chemical signal was present in the cytoplasm of dividing cells that was responsible for "telling" the cells that they should proceed into mitosis. By fractionating the cytoplasm into its components, scientists were able to isolate the signal that triggers mitosis.</span>
Answer:
Genetic diversity has decreased due to inbreeding due to dwindling population size.
Answer:
A= ionization of particles
Explanation:
Plasma:
" The ionized gaseous mixture consist of atoms, ions and electrons is called plasma"
The plasma was first time identified by William Crookes in 1879. More than 99% universe matter is consist of plasma.
It is the fourth state of matter, the other three are solid, gas and liquid. The most of matter in the universe is plasma. When heat is supplied to the atoms, they gain energy the electrons in atom thus escape from the atom by gaining the energy and create the positive charge. Thus ions are formed. When heat is constantly supplied, the ionization process continue to take place and produce large number of positive charges, free electrons but some atoms not get ionized and remain neutral. Thus a cloud of free electrons , positive charge and neutral atoms is formed which is called plasma.
