The right answer is spiral.
Size and shape vary from one bacterium to another. The majority of bacteria have a size between 0.5-5 μm in diameter.
Most bacteria are either spherical or rod-shaped. In the first case they are called cocci (of the Greek kókkos, grain) and in the second bacilli (of Latin baculus, rod). There are also intermediate forms: coccobacilli. Some rod-shaped bacteria are slightly curved like vibrio. Other bacteria are helicoidal. They are spiral if the form is invariable and rigid, spirochaetes if the body is flexible and can change shape.
The answer is <span>the evolutionary process through which new species emerge.
Speciation is </span><span>the evolutionary process through which new species emerge. It is the consequence of reproductive isolation of populations which then become distinct species.
Through the process of elimination:
- A</span><span>n inherited or learned trait that increases an organism’s chance of survival in its environment is an adaptation.
- A</span><span> process by which organisms that are better adapted to their environment tend to survive, reproduce, increase in number, and pass their traits on to succeeding generations is natural selection.
- A</span><span> process by which one of the extreme variations of a trait is favored is directional selection.</span>
The answer is “Splanchnic Nerves”. Splanchnic Nerve are
nerves that are composed of preganglionic sensitive axons, which were not able
to synapse in a sensitive ganglion. Splanchnic nerves are matching instinctual
nerves, which backs up to the innervation of the inner body parts. These are
nerves that are transporting fibers of the autonomic nervous, as well as sensual
fibers from the different body parts
