Motor neurons carry impulses to the effectors in the body, which are the muscles or glands that produce a change based on a stimulus sensed by the receptors. The motor neurons "innervate" muscle fibers, which essentially means that they cause them to move. The fewer the muscle fibers associated with a motor neuron, the more precise are the movements of those fibers. Having to control a small number of fibers, the neuron is able to coordinate more dexterous motions. An example of a region where there are not a lot of muscle fibers related to each neuron is in your fingers.
Answer:
Evolution refers to the change in the structure of an organism with the passage of million of years.
Explanation:
Evolution is the change in the structure of an organism with the passage of million of years. Evolution occurs due to two reasons, first from genetically while the other from adaptation to the environmental conditions. In genetically, the change in structure of animal comes from their parents whereas changes occurs due to adaptation of an organism in order to survive in the harsh climatic condition of the environment.
Answer:
A. The variation resulting from meiosis and the union of gametes means some individuals will have a chance of colonizing diverse distant environments successfully.
D. Vegetative propagation is more efficient than sexual reproduction when the current generation is well adapted to the local environment.
DNA microarray uses 20-40 sequence-specific oligonucleotides as probes to identify the SNP.
DNA microarray is a technique used to measure gene expression. It works on the principle of hybridization.
The genome of the reference organism is attached to a solid surface (silicon chip). The DNA of the test organism is made to hydride with the reference organism. Depending on the level of hybridization the fluorescent or the chemiluminescent is measured to identify the expression.
Single nucleotide polymorphism (SNP) is the change in the single nucleotide of the genome. SNPs can be identified with the help of DNA microarray.
