I beleive the answer is D, it is called the Nutrients cycle.
When it comes to temperature regulation we can classify animals into two different groups, the endotherms, and the ectotherms.
Most mammals and birds are endotherms, which means they can alter their body temperature through their metabolic processes and be independent of the external sources of heat.
On the other sides, many reptiles are ectotherms, which means that they have to rely on external sources of heat, such as the sunlight, to maintain their body temperature
Animals also can be classified into three different groups based on the type of their skeletons. Vertebrates possess an inner skeletal system called the endoskeleton, the arthropods possess external skeleton called the exoskeleton and many soft-bodied marine animals possess hydroskeletons, bodily support systems made out of fluid-filled coelom.
1. Physical properties of the planets vary in a systematic fashion as a function of distance from the Sun.
Planets and Sun revolve and orbit in a west-to-east direction. The planets obliquity (tilt of rotation axes to their orbits) are small. Uranus and Venus are exceptions.
The planets differ in composition. Their composition varies roughly with distance from the Sun: dense, metal-rich planets are in the inner part and giant, hydrogen-rich planets are in the outer part.
The Moon include its distance from the Earth, size, mass, density, and temperature
2. Asteroids - large, rocky bodies
Comets -
smaller, made of ice, rock, dust
I don't know if this is what you want, but please please correct me if I'm wrong!! :)
Answer:
The correct answer is - option D. historical particularism.
Explanation:
Historical particularism is the very commonly accepted case of the school of thought related to the comparative study of the cultures. It has declined other evolutionary model of that time.
According to this model, there is some universal law for the development or cultural evolution. It mean if the societies or cultures are able to develop to the various paths to same level of cultural development.
Thus, the correct answer is - option D. historical particularism.
Microtubules in Mitosis. Microtubules play a role in the migration of chromosomes to opposite ends of a mitosing cell during the anaphase.
