Answer:
Photosynthesis and cellular respiration are chemically opposite. The reactants of photosynthesis are energy, carbon dioxide (6CO2), and water (6H2O). The products of cellular respiration are energy, carbon dioxide, and water. The products of photosynthesis are glucose (C6H12O6) and oxygen (6O2), and the reactants of cellular respiration are glucose (C6H12O6) and oxygen (6O2). So, the processes' equations are chemically opposite. The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Without photosynthesis, cellular respiration couldn't take place, and without cellular respiration, photosynthesis couldn't take place. It's like a cycle.

Hello there!
Ripping up a peice of paper is considered physical change. 
Physical change means its still the same, it just changed shape.
Chemical change cannot be changed back.
For ex) Burning paper.
Its a chemical change because it cant be undone
hope this helps!

<u>Answer</u>: Appear to function in similar ways across diverse groups of organisms.
<u>Explanation</u>:
- The <em>hox</em> genes are a subset of homeotic genes.
- The function of the hox genes is to control the development of the body plan of an individual during the embryonic stage.
- Thus, the basic body form of an organism is laid down with the help of these genes.
- <em>These genes are present in many different species from fruit fly to mice to humans</em>.
- The reason that they are present in different organisms is that there was a common ancestor that possessed the hox gene cluster and then the genes were passed on to different vertebrates. However, the slight changes that have occurred in these genes are due to duplication events.
