Answer:
Brain is the main coordination center of the body and regulates the proper functioning of the body. Brain is divided into three parts- forebrain, midbrain and hindbrain.
Cerebrum: Crerebrum is the largest part of brain and controls the language, communication ability, and the process of learning and memory of an organism.
Hypothalamus: Hypothalamus is located at the base of a brain. Hypothalamus releases various hormones, regulates the body temperature and manages the sexual behavior of an organism.

One unique feature of stratosphere is that it contains a layer of ozone gas, which protect us from the sun's rays.
A cell can be thought of as a "factory," with different departments each performing specialized tasks.
1-metaphase, since an ecuatorial plate is formed
2.prophase since the nuclear envelope is starting to dissapear
3.Telophase since new nucleae started to form around each separated genetic material
4.Interphase
5.Interphase
6.Interphase
7.anaphase since genetic material(chromsomes) is pulled to the poles of the cell
8.Interphase
9.Anaphase
10.Interphase
11.metaphase
12.telophase
13.Interphase
14.Prophase
15.interphase
16.interphase
17.metaphase
18.interphase
