Answer 1

You can google these things bro, still I'll do it for you.

• Parturition -: Parturition is the process of delivering the baby from the uterus into outside environment by a female. The contractions and dilation together are called as labor pains. Lab our pains are brought about by the hormone Oxycontin. Parturition helps in expelling the baby as well as the placenta.

• Glucagon -: Glucagon is a peptide hormone, produced by alpha cells of the pancreas. The pancreas releases glucagon when the concentration of insulin (and indirectly glucose) in the bloodstream falls too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream.

• Placenta -: A special tissue embedded in the uterus wall with the help of which human embryo gets nutrition from mother’s blood.
• Cowper Gland -: Cowper glands produce a clear, slippery fluid, This fluid serves to lubricate the urethra and to neutralize any acidity. Fluids from the prostate, the seminal vesicles and Cowper's glands make up the bulk of semen.
• Biodegradable waste -:  A biodegradable material can be defined as a material which can be decomposed by b bacteria or other natural organisms and not be adding to pollution.
• 3 R's -: The three R's - reduce, reuse and recycle - all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space and energy.
• Symbiotic Relationship -: A symbiotic relationship means a mutually interdependent relationship. Two different kinds of organisms live together for their mutual benefit.
• Hormones -: Hormones are chemical substances produced within an animal or a plant which act as "chemical messengers" as means of communication among various parts of an organism. They help these parts function in a coordinated way. Hormones control such body activities as growth, development, and reproduction.

Hope this helps. Cheers!
