<span>The
answer is D. So as to take the shortest time to react to stimuli, most sensory neurons
are looped through the spinal cord to motor neurons. Following a reflex action,
the signal is later passed to the brain, from the spinal cord, for the signal
to be analyzed. A reflex arc is divided into
somatic and autonomic reflex arcs. The former is connected to outer muscles
while the later to inner organs. </span>
<span>Natural selection is when
species learn to adapt to their environment. They could (1) differential
reproduction, that is, not all organisms are able to reproduce to their fullest
capacity because nature cannot simply sustain it and (2) acquire genes, that is
heredity. Certain characteristics of organisms tend to survive if it continues
to strive. If it survives, this trait is passed down to the next generations
forgetting the other traits but only the one who could survive the environment.
Therefore it is true that <span>natural selection is when
‘organisms inherit advantageous traits, and tend to reproduce more successfully
than other organisms’</span></span>
1. Find AUG (start codon) in RNA strand
2. Break strand into condom (3 bases)
3. Use amino acid codon chart (above) to find the amino acid sequence. Continue until stop codon.
