Answer:
The human body have two parts of nervous sytem the peripheral nervous system and the central nervous system
Explanation:
Peripheral nervous system contain all the nerves and ganglion that lies out side of the spinal cord and the brain.These two systems communicate with each other to make the body functional. The main function of the PNS is to connect the CNS to limbs and organs. Unlike the CNS the PNS is not protected by the vertebral column and skull.The peripheral nervous system is divided in to the somatic nervous system and the autonomic nervous system. The autonomic nervous control on the smooth muscles and glands.The connection between the CNS and organs keeps the body in sympathetic or parasympathetic condition.
Answer:
Following are the six accurate statements:
1. The seeds allow the plant embryos to get dispersed over the long distances from the parent plant through animals or wind.
2. In various angiosperms, the male gametophyte comprised in a pollen grain can get translocated various miles away through animal or wind.
3. Fruits help in the dispersal of seeds by animals or wind, which eat or carry the fruits.
4. The fruits protect the seeds, and the seeds nourish and protect the plant embryos.
5. The floral components of the sporophyte safeguard the reduced female gametophyte from dying out and from ultraviolet radiation.
6. Flowers fascinate animal pollinators carrying pollen from other plants of the similar species.
The other mentioned statements are incorrect. The spores are not generated in the angiosperms, however, seed gets produced post-fertilization that comprises developing embryo. The cotyledons exhibit stored food substance and seeds are comprised within the seeds. The seeds get dispersed with the help of abiotic and biotic agents.
The fertilization in angiosperms is not reliant upon the water, it is rather the pteridophytes and bryophytes that cannot complete their life cycle in the absence of water. In angiosperms, the main plant body is sporophyte that safeguards the female gametophyte.
