1) Select ONE animal species. Your goal is to explain the way where an evolutionary change might happens for a particular characteristic (trait) of the population of that species as a result of natural selection.
The characteristic (trait) could be something such as coloration pattern, length of limbs, size of teeth or beak, or any measurable trait that is inherited.
The organism you select should be a real one however the evolutionary change in a trait which you explain can be real or fiction.
In your own words,
a) Describe how the change in this trait takes place. You will explain the trait within the population at starting point and then what the trait will look like at the later time, as a result of natural selection.
b) Assure to explain the process through which the changes take place. Explain the selective pressure? Describe why change might confer more fitness to the particular environment?

Some wines are marketed as "sparkling" wines. Sparkling wines are considered so because of a dissolved gas that makes them fizzy. Concern what you know about the procedure of respiration to explain the type and origin of this gas.
The "Primordial soup" includes the mixture of elements and gases which are thought to have started life on the Earth. Speculate on how, over the course of evolution, these complex molecules would eventually form the complex life forms such as human..
What type of electrode would they need to use (express material and design)? Provide a simplified schematic (circuit model of the electrode) described in the notes. Also discuss at least two benefits of an exoskeleton as well as how arthropod grows ..
