Answer:
Dendrites
Explanation:
Dendrites or dendrons are the branching of protoplasmic extensions of a nerve cell. As the neurons are arranged in head to tail manner, these dendrites lie close to the axon terminals of the other neuron and thus they receive signals from the other neurons and then pass the received signal to the main body of the neuron which is also called Soma. The electrical signals are passed from one neuron to the other neurons via the synapses which are located at various points on the dendrites.

Answer: C). Neurons
Explanation:
Neurons are the specialized cells present in the brain. These cells play an important role in processing and transfer of information generated as a response to stimuli. The neurons have specialized parts which recieves the signals from dendrites and send the signal to other neuron by axon. In this way transfer of information takes place from cell to cell.
Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.
<span>A long-necked, short-legged, light-spotted, maize-digesting giraffe could have a genotype of NN (or Nn), ll, dd, and MM (or Mm). Due to the fact that long necks are dominant, the giraffe would only need one dominant allele to have the phenotype. Therefore the giraffe could have two dominant alleles or one dominant and one recessive. Because long legs and dark spots are dominant, the giraffe must have two recessive alleles for each of these traits. As for maize digestion, the giraffe only needs one dominant allele to have the trait, so they could be MM or Mm.</span>
