Nervous System: an extensive network of specialized cells that carries information to and from all parts of the body. Neuron: the basic cell that makes up the nervous system and that receives and sends messages within that system. Dendrites: branchlike structures that receive messages from other neurons. Soma: the cell body of the neuron responsible for maintaining the life of the cell. Axon: tubelike structure that carries the neural message. Glial cells grey fatty cells that provide support for

Chapter 7 * Why do we want to make Eukaryotic cell proteins? * Because when eukaryotic proteins are expressed in prokaryotic cells problems like been unstable‚ no biological activity and prokaryotic contaminants ( pyrogens) can occur. * Also to make the protein as natural as possible * The same expression vectors as we need for pro * We don’t need shangdolron coz that only for pro Transformation: in Eukaryotic cells: in humans means that difference in growth characters

drag-causing long necks. Massare (1988) made the same conclusion‚ since the hydrodynamic properties of the Plesiosauroids indicate the species moved no faster than 2.3 metres every second. Therefore‚ the species was confronted by a conundrum: it sought to dive hundreds of metres to hunt its prey yet was constrained‚ by virtue of its body shape‚ to

Harbor Seals Harbor seals inhabit the costal regions of the North Pacific and Atlantic oceans‚ and the Arctic regions. They can dive to 1450 feet and stay submerged for 25 minutes. The harbor seal weighs around 180 pounds and are six feet in length. Pups weigh about 24 pounds at birth. Harbor seal pups appear skinny when born and make sounds like they are crying. Harbor seals inhabit areas that are also frequented by humans and are easily disturbed. When disturbed the mothers sometimes abandon

Introduction The type of communication used to transmit information is closely related to the animal’s lifestyle and environment. This can be seen in most terrestrial mammals which are nocturnal so use olfactory and auditory which work as well in the dark as they do during the day. Visual communication would be relatively ineffective in this lifestyle. In contrast humans are diurnal and use primarily visual and auditory signals for communication‚ but miss many chemical cues which many other

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one
