False. It is not a natural process. Humans choose the desirable features of a particular dog and selectively breed it. These dogs have not adapted to the environment. This selection is mostly based on cosmetic reasons or other desirable features. These dogs prob wouldn't be able to survive in the wild
A reflex action is caused by a nerve or nerves and voluntary muscle. A hormonal reaction caused by the hormone's end organ's biochemical reaction to the hormone. Hope this help's
The gate control theory of pain states that the experience of pain is dependent on the complex interaction of the central and the peripheral nervous system. This theory was given by Ronald Melzack and Patrick Wall.
Usually, when a person experiences pain, the neurons transmits the message from the area of damage along the peripheral nervous system to the spinal cord and the brain. The gate control theory suggests that the neurons encounter the 'nerve gates' while transmitting the pain messages in the spinal cord. These opening and closing of these gates is dependent on the multiple factors.
The basket cells are the multipolar, inhibitory interneurons . Endorphins are the neuropeptide and the peptide hormones, which are secreted by the central nervous system and the pituitary gland. These structures have no relation with the transmission of the pain.
The hyperpolarization of the neurons by the opiate receptors resulting in the release of the substance P, which is a neurotransmitter involved with pain.
Hence, the correct answer is 'by releasing substance P'.
Answer: A. Geological processes continue over millions of years.
A swamp is a wetland which exhibit the growth of vegetation. It consist of vegetation which is being dominated by trees. When these trees die, the wooden parts sank below the water. The wood remains being deposited at the bottom of the water body causes the formation of coal. Coal formation results due to the wood being compressed and buried. It takes millions of years for the transformation of wood into coal in the geosphere of the swamp region.
Hence, formation of coal is a geological process and it takes millions of years for it's formation.
A I think that is how lightning works anyways
