Ecosystem
Explanation:
The relationship between the living and non-living things forms an ecosystem.
The non- living things like water, air, soil and other are required by the living organisms for leading their life cycle.
The living things forms the integral part of the natural cycling process of water, air and soil.
Thus this can be said that both living and non-living things are interdependent on each other and forms an ecosystem.
For example, if plants do not get water they will not be able to produce food also the transpiration will not occur which is an important part of the water cycle.
Answer:
it can rise up from the water then make a cloud next it will rain and repeat
Explanation:
Answer:
<em>Comparisons of items eaten for food</em>
Explanation:
If we compare the diet intake of different organisms we will not be able to predict whether the organism has an evolutionary history or not. Hence, comparisons of items eaten for food is the LEAST useful technique to explore evolutionary history among organisms.
Other options mentioned will however be beneficial in understanding the evolutionary history among organisms. For example, analysis of DNA strands of different animal species will tell us the similarities and differences in the DNA strand. As a result, we will e able to predict whether they have evolutionary history or not.
The solution of sodium acetate trihydrate energy released is 19.7 kJ/mole which is an endothermic process. The crystallization is exothermic.
<h3>
What is crystallization?</h3>
Crystallization can be defined as the solidification of a liquid substance into a highly structured solid whose molecules are placed in a well-defined three dimensional crystal lattice.
A. Before weight: 280gm and after heating of pad, weight increases by 10-20gm approx (300gm).
B. It takes 12-20 minutes for the solution to completely crystallize after the bag is activated.
