The correct answer is option D, Plasma
Plasma is the condition where a hot gas is ionized. It consists of equal numbers of positive and negative ions. It is an electrically conducting environment which is considered as the fourth state of matter. Plasma gases are affected by electric and magnetic waves as compared to the neutral gases (which remain unaffected by electric and magnetic wave) due to the presence of negative and positive ions.
Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
