<u>Answer</u>: Option 4 The genes in each type of cell are being expressed differently

<u>Explanation</u>:

  • Both skin cells and muscle cells are somatic cells i.e the cells that make up the body parts.
  • Since, both of them are somatic cells they both contain the <em>same number of chromosomes</em> which  in case of humans is  23 pairs.
  • The set of genes present in each type of cell in the body is the same and therefore, both muscle cell and skin cells have the same genes.
  • The reason why muscle cells and skin cells do not look and act the same is that even though these cells contain the <em>same genes</em>, there is <em>differential expression of genes</em> in these cells.
  • Differential expression of genes basically means that different combination of genes are activated in a cell which plays a role of defining the purpose of the cell.
  • This means that the set of genes that are activated in the skin cells are different from that of the muscle cells.
  • As the <em>genes are being expressed differently</em> in the muscle and skin cells, both these cells acquire different characteristics and thus, look different and perform different functions.

So out of all the options, option 4 is the correct one.

The oxygen that is released as o2 during photosynthesis came from _____________ molecules.
AlexFokin [52]

Answer:

Water (H2O)

Explanation:

Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
