Answer:
An ECG provides direct information about valve function. False- B.
Answer:
caused by a genetic defect on chromosome 4. The defect causes a part of DNA to occur many more times than it is supposed to. This defect is called a CAG repeat
Explanation:
B. Simple columnar epithelium
SCE is in all skin, lung, and blood vessel walls.
Schema, assimilation and accommodation
Explanation
Schema, assimilation and accommodation are three important concepts in Piaget’s cognitive development which the kids adapt to learn and understand their world.
Schema is the mental or cognitive idea, concept or framework which organizes and interprets information. Schema is built continuously during cognitive development of children through the interweaving of the adaptation processes of assimilation and accommodation.
Assimilation helps a kid to take new information and add it to the existing schema or old information about the same concept. For ex., identifying a four-legged animal as a cow by a kid is assimilation of a new information.
Accommodation helps a kid to analyze and modify the new or old schema or information based on what is learnt or experienced. For ex., Identifying that all four-legged animals are not cow and they can be a horse or bullock also depending upon the difference in their structure is the accommodation made by the kid on top of existing schema of four-legged animals.
Answer:
The processing power of the mammalian brain is derived from the tremendous interconnectivity of its neurons. An individual neuron can have several thousand synaptic connections. While these associations yield computational power, it is the modification of these synapses that gives rise to the brain's capacity to learn, remember and even recover function after injury. Inter-connectivity and plasticity come at the price of increased complexity as small groups of synapses are strengthened and weakened independently of one another (Fig. 1). When one considers that new protein synthesis is required for the long-term maintenance of these changes, the delivery of new proteins to the synapses where they are needed poses an interesting problem (Fig. 1). Traditionally, it has been thought that the new proteins are synthesized in the cell body of the neuron and then shipped to where they are needed. Delivering proteins from the cell body to the modified synapses, but not the unmodified ones, is a difficult task. Recent studies suggest a simpler solution: dendrites themselves are capable of synthesizing proteins. Thus, proteins could be produced locally, at or near the synapses where they are needed. This is an elegant way to achieve the synapse specific delivery of newly synthesized proteins.
