Answer:
centromere
Explanation:
Chromosomal inversions, as its name suggests, are alterations that occur when a portion of the chromosome splits off but rejoins the chromosome in reverse. The genetic material remains the same, however, the disposition of information occurs in a exchanged manner.
We can classify chromosomal inversion into two types:
- Pericentric: Pericentric inversion occurs when the region undergoing inversion surrounds the centromere.
- Paracentric: Paracentric inversion occurs when the inverted region does not involve the centromere.
There's multiple differences between the endotherms and the ectotherms, with the most important being:
- The endotherms maintain a constant body temperature, while the ectotherms's body temperature fluctuates with the environmental temperature.
- The endotherms have developed protection (hairs, feathers) from the outside influences, while the ectotherms do not have such accessories.
- The endotherms are warm-blooded, while the ectotherms are cold-blooded.
- The endotherms are usually bigger if the climate is colder, while the ectotherms are usually bigger if the climate is warmer.
- Endotherms are the mammals and the birds, while ectotherms are the reptiles and most of the invertebrates.
Answer: Polystyrene - Polybutadiene or also known as: Styrene-Butadiene
Answer;
-Flagellum (flagella; plural)
Explanation;
-Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea.
-A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi.
-The primary role of the flagellum is locomotion, but it also often has function as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. Flagella are organelles defined by function rather than structure. Flagella vary greatly. Both prokaryotic and eukaryotic flagella can be used for swimming but they differ greatly in protein composition, structure, and mechanism of propulsion.
