Answer:
Clone, also spelled clon, cell or organism that is genetically identical to the original cell or organism from which it is derived.
During exercises, our muscles needed energy for contractions. The heart pumps more rapidly and more powerfully during this time for a few reasons.
First, more oxygen and nutrients like glucose can be transported to the heart. Muscle cells uses oxygen and glucose for aerobic respiration to generate energy.
Secondly, more carbon dioxide and waste can be transported away from the muscles. Waste products from aerobic respiration includes carbon dioxide or water etc. The faster the heart pumps, the faster the blood gets transported so more waste can be carried away.
Thirdly, lactic acid can be carried away too. When oxygen supply is not enough, the cells undergo anaerobic respiration to generate energy. This type of respiration does not require oxygen, but a waste product called lactic acid is produced. Lactic acid must be carried away from cells because they're harmful. Therefore, the faster the heart pumps, the more lactic acid gets carried away.
Last but not least, heat can be carried away too. Part of the energy generated is turned into heat. Therefore, in order to help us cool down, blood travels fast to carry heat away from the heat generating muscle cells.
Answer:
Vegetative propagation is the process of multiplication in which a portion of fragment of plant body functions as propagate and develops into a new individual.
Explanation:
- Asexual or vegetative propagation of plant is that form of plant propagation in which the new individual arises from any vegetative part of the parent and possesses exactly the same characteristic of the parent plant.
- Vegetative propagation can be carried out through roots as in <em>Dalbergia sissoo</em> (Shisham) ; <em>Psidium guajava</em> (Guava) etc; through stems as in <em>Solanum tuberosum</em> (potato) ; through leaves as in<em> Bryophyllum</em>.
- Plants can be propagated artificially by following natural principle.
- Some artificial methods of vegetative propagation include, Cutting, grafting, budding etc.
Aerobic respiration to lactic acid fermentation, lactic acid is the reason your muscles get sore after a workout
