1) in complex animals, a nervous system is present. it is composed of a brain and a nerve cord ( called a CNS in vertibrates)
The PNS (peripheral nervous system) is composed of all nerve cells, known as neurons and projections of their plasma membranes that are outside but connected to the brain and/ or nerve cord.
The nervous system is the part of an animal which coordinates its actions by transmitting signals to and from different parts of body. It consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS) in vertebrates. The CNS consists of the brain and spinal cord. The dorsal nerve cord is a hollow cord dorsal to the notochord. It is formed from a part of the ectoderm which rolls, forms the hollow tube. The dorsal nerve cord is later modified in vertebrates into the central nervous system which is composed of the brain and spinal cord.
PNS is all other neurons and projections of their plasma membranes outside of the CNS consists braina and nerve cord.

Questions 1 pts Humans and many other diurnal animals have three types of cones - one stimulated maximally by blue light, a second maximally stimulated by green light, and a third stimulated maximally by red light. How can human beings see colors such as orange, yellow and purple? When red cones are stimulated, they inhibit blue and green cones. When blue cones are stimulated, they inhibit only green cones. Green cones when stimulated, do not inhibit other cones, but do...

please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...
