a social group can be defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Other theorists disagree however, and are wary of definitions which stress the importance of interdependence or objective similarity. Instead, researchers within the social identity tradition generally define it as "a group is defined in terms of those who identify themselves as members of the group."[3] Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group.

Answer:
Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.
Explanation:
Active Transport works against the concentration gradient and therefore needs energy to make it happen
Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy
Answer:
- "Mid oceanic ridge"
Explanation:
<em> Mid-ocean ridges are formed by divergent plate boundaries in the ocean. This is where upwelling magma creates new seabed. A diverging plate boundary occurs when two plates move away from one other. Magma rises from deep beneath the Earth and erupts along these boundaries, forming new crust on the lithosphere. The majority of divergent plate borders are undersea, forming submerged mountain ranges known as oceanic spreading ridges. </em>
Hope this helps! :D
