<h3><u>Answer;</u></h3>
Vestigial Structure
<h3><u>Explanation;</u></h3>
- <em><u>Vestigial Structure are structures that have no apparent function and appear to be residual parts from a past ancestor.</u></em>
- Vestigial structures are normally homologous to structures that are functioning normally in other species and therefore may be considered evidence for evolution.
- Other examples of vestigial structures include; the human appendix, the pelvic bone of a snake, and the wings of flightless birds.
Answer: Ethylene
Explication: Ethylene is a hydrocarbon which has the formula C ₂H ₄ or H₂C=CH₂. It is a colorless flammable gas with a faint "sweet and musky" odor when pure. It is the simplest alkene. Ethylene is widely used in the chemical industry, and its worldwide production exceeds that of any other organic compound.
Answer:
The correct answer is option - Golgi apparatus.
Explanation:
Golgi apparatus is the cell organelle that is integral in sorting, modifying, and packaging the macromolecules for secretion from the cell. The Golgi plays an important function in the synthesis of carbohydrate, and proteoglycans.
The Golgi apparatus packaged proteins into vesicles and these vesicles transported to the target site like cell membrane and secreted by the process of exocytosis.
Thus, the correct answer is option - Golgi apparatus.
