What’s vegetative reproduction (biology)<br><br> give description and example.
Virty [35]

Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.

Examples are:  Onion, rhizome (ginger) and daffodil

Explanation:

There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.

Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.

Ganezh [65]
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.

The exchange of wastes through the skin is just called excretion by sweating. 

There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.

The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
