Correlational study is used to show the type of association or relationship which exists between two or more variables using statistical analysis. Ken's research shows that <em>there</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>relationship</em><em> </em><em>between</em><em> </em><em>childhood</em><em> </em><em>anger</em><em> </em><em>management</em><em> </em><em>and</em><em> </em><em>adult</em><em> </em><em>earning</em><em>.</em><em> </em>
- According to Ken's research, learning how to control anger leads to making more income during adulthood. This signifies a positive relationship between good anger management in childhood and earning made during adulthood.
- Similarly poor anger management in childhood leads is associated with low earning during adulthood.
- Hence, Ken's research shows that there is a relationship between <em>childhood</em><em> </em><em>anger</em><em> </em><em>management</em><em> </em><em>and</em><em> </em><em>adult</em><em> </em><em>earnings</em><em>.</em><em> </em>

Answer:
Due to cell wall.
Explanation:
Scientists were able to easily identify the cells in plants first as compared to animal cell because the plant cell has cell wall while the animal cell has no cell wall only cell membrane. The structure of plant cell is just like the compartments and the cell wall provides the boundary between two cell which enable the scientist to see the plant cell first.
Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature.
