Contrast growth in living and nonliving things
miv72 [106K]
<span>When you talk about growth, it refers to development either in size, state or ability, the capacity. Growth in living organisms are resulted from acquiring nutrients, being able to function in adaptation, irritability, reproduction and excretion. On contrary, these functions are absent in nonliving things. When you say growth in nonliving things it’s either by addition of matter or magnitude. The process is called accretion but this doesn’t mean maturation or aging in living organisms. Maybe rusting or oxidation is caused by the chemical change, toxification but not growth just chemical reaction.  </span>

WHOEVER ANSWERS FIRST GET A BRAINLY!!!!Provide a reason why no 2 communities are ever the same. Support your answer with an exam
Advocard [28]

Answer:

No two communities are the same because each one has something specific to them whether it is house structure, rules of the community, how big the community is, and the people that live there.

Explanation:

A great example of this is Weston, FL and Pembroke Pines, FL. In Weston you will find higher class people living there such as celebrities and athletes. The best community to use as a comparison is Botanica Weston. There are mansions in that neighborhood along with many sport icons living there. In Pembroke Pines, it is more of a family based city. In the community Pembroke Falls, you will see more family type houses and a large clubhouse with a pool, game room, and event room to host parties in. Each community has a different identity and no two communities are the same.
