Answer:
The correct answer will be option-D.
Explanation:
Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.
The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy. This absorption causes the excitation of the electrons provided by the chlorophyll molecule.
The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.
This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.
Thus, option-D is the correct answer.
The connective tissue is among the four major classes of the tissue. It is the most widely distributed and the most abundant class of the tissues. However, the type of tissue in every organ varies. Composed of cells, fibers and matrix, this type of tissue is different in different organs of the body.
The variability in it's type is provided by the difference in the degree of the order of the cells, fibers, and the matrix. This variability contributes to the diversity of this tissue.
Hence, the blank can be filled with 'diversity'.
Items such as sheet metal, treated lumber, corn syrup, and plastics are examples of processed materials.
Processed materials are materials which have been refined or built by humans from raw materials.<span> Processed materials are different from component parts as they become part of a finished product and don't retain their original identity.
</span><span>Ceramic is a processed material. You have to add several materials, heat them, sinter them and then you get ceramic.</span>
Nucleic acids<span> are long polymers of repeating </span>subunits<span> called nucleotides. Each nucleotide is made </span>up<span> of three smaller building blocks (Figure 17): Figure 17 The structure of a nucleotide and the formation of </span>nucleic acid<span> chains.</span>
