Answer:plastics
Answer:
Mesophyll Cells
Explanation:
The mesophyll cells are the inside tissue of a plant which contain chloroplasts, and chloroplasts are by definition, found in green cells.

Because Larry was daydreaming and was not attentive in class,
Answer:
Option). Increasing enzyme, increasing substrate, increasing co-factors
Explanation:
Enzymes are bio-catalysts that increase the rate of a chemical reaction by decreasing its activation energy. As enzymes are catalytic molecules, increasing enzyme concentration would increase rate of reaction.
Substrates are those substrates that react with other molecules to form products. Thus, increasing the concentration of substrates, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.
Co-factors are non-protein compounds or ions, which are required for proper functioning of many enzymes. Thus, increasing the concentration of co-factors, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.
Thus, the correct answer is option). 'increasing enzyme, increasing substrate, increasing co-factors.'
<span>The essential unit of DNA packaging is the nucleosome. A nucleosome consists of a small amount of DNA wrapped up with protein. The proteins that interact with DNA to form chromatin comprise a family of basic (positively charged) proteins called histones. There are five different types of histone protein: H1, H2A, H2B, H3, and H4. Of these, two molecules each of H2A, H2B, H3, and H4 combine to form a histone octamer. DNA wraps around the octamer, making 1 3/4 turns around the protein complex. The amount of DNA associated with the histone octamer is 146 bp. The octamer plus the DNA comprise what is called the nucleosome core. A small stretch of DNA (60 bp) runs between adjacent nucleosome cores, and is known as the linker. A single nucleosome consists of one core plus a linker. The total amount of DNA involved in a single nucleosome is approximately 206 bp. Chromatin therefore consists of DNA wrapped around one histone octamer after another, like a long string of beads.</span>
