Answer 2

Question 1

The ability of the arm to bend at the elbow is due to muscular tissue. The elbow joint is moved when muscles contract, pulling on tendons attached to bones. Muscular tissue contains muscle cells that have the ability to contract and relax, allowing for movement.

The other tissue options can be ruled out: - Connective tissue (option C) provides structure and binds other tissues together, but does not directly cause movement. - Nervous tissue (option B) transmits signals from the brain but does not contract to produce movement. - Epithelial tissue (option A) forms protective layers and linings but does not contract.

Question 2

If a white chrysanthemum is placed in a solution of red dye, its petals will eventually turn pink. This is due to vascular tissue (option A). Vascular tissue contains xylem and phloem which transport water and nutrients throughout the plant. The red dye will be transported through the vascular tissue to the petals via transpiration, turning them pink.

The other tissue types do not transport materials in this way: - Epithelial tissue (option B) forms protective layers but does not transport substances. - Mechanical tissue (option V) provides support but does not transport. - Connective tissue (option G) binds tissues together but does not transport fluids.
