<span>The reason why the modern cockroaches have certain additional genes which allow them to survive in today’s colder climate is because of evolution. The species can grow to be able to live in certain environments. Cockroaches are to some degree summed up creepy crawlies without extraordinary adjustments like the sucking mouthparts of aphids and other genuine bugs; they have biting mouthparts and are likely among the most primitive of living neopteran bugs.</span>
Answer:
Microtubule fiber
Explanation:
Microtubules play a huge role in movement within a cell. They form the spindle fibers that manipulate and separate chromosomes during the mitosis phase of the cell cycle. Examples of microtubule fibers that assist in cell division include polar fibers and kinetochore fibers.
The primary function of a flagellum is that of locomotion, but it also often functions as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. The similar structure in the archaea functions in the same way but is structurally different and has been termed the archaellum.
The Cytoskeleton is a dynamic three-dimensional structure that fills the cytoplasm. This structure acts as both muscle and skeleton, for movement and stability. The long fibers of the cytoskeleton are polymers of subunits.
The opposite term is filament fibre, which is fibre that comes in continuous to near continuous lengths for use. Silk, taken from the cocoon of a silkworm, is a filament. Synthetic fibres can also be manufactured as filament. If the filament is then cut into discrete lengths, it becomes staple fibre.
Hope this helps : D
Answer:
Natural selection is an important contribution to the theory of evolution because it increases an individual's ability to survive and compete and reproduce.
