Answer:
1) Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
2) The SI unit of time is the second.
4) spores
Ferns, fungi and mosses reproduce by releasing millions of spores through the air. The spores are fed eggs and are spread through the environment by wind. Mosses don't have flowers or seeds, but use spores to reproduce.
6) rib cage
During normal breathing, contraction of the major inspiratory muscle, the diaphragm, produces both rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative relative to atmosphere.
7) Anaerobic Respiration –Takes place in the absence of oxygen.
8) SI unit of distance is a meter according to the International System of Units. Interestingly, using this as the base unit and some equations, many other derived units or quantities are formed like volume, area, acceleration, and speed.
