Answer:
sympatric speciation
Explanation:
Species of fruit fly larvae in the genus Rhagoletis each feed on a particular kind of fruit. Rhagoletis pomonella feeds on the small red fruit of the hawthorn tree. In 1865, farmers in the Hudson River valley found that R. pomonella flies had begun attacking their apples and then spread to apple orchards in adjacent areas of Massachusetts and Connecticut. These now separate varieties of flies, the apple and haw flies, usually don't interbreed with each other because their periods of mating coincide with the different ripening times of apples and hawthorn fruit. Each variety is becoming specialized to feed and reproduce in its own particular microhabitat and may be transitioning to separate species.If the apple and haw flies become distinct enough to be separate species, their evolution is an example of sympatric speciation
When faced with dangers close to both sides of your path of travel you should create more space to the side with the most serious consequences. There are several dangers and obstacles on the roadway and Tips to Avoid them which include; a deer in the headlights,unidentified flying objects on the roads, slow moving vehicles, speed bumps, pedestrian and pet such as dogs, cats may be common obstacles. It is always important to weigh the extent of dangers while faced with dangers on both sides of the paths.
In general, there are three types of Cell division :
- Binary fission, a division process on which a cell is completely cloned, forming 2 exact same cells
- Mitosis , a division of a somatic cell of Eukaryotic organisms
- Meioses, a cell division that produces gametes

<h2>Fixation</h2>
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
<h3>Biologically: </h3>
Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
<h3>Through lightning: </h3>
Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
