This relationship between the plant and the animal represents mutualistic symbiosis; they have a symbiotic relationship which is mutualistic.
Plants benefit by having their seeds dispersed to farther areas when animals eat their nutritious fruits. So, animals gain from the plants since they are able to attain nourishment for themselves. Both benefit from each other at the same time when an action is done, and so, their relationship is mutual.
Hope this helps! :)

Answer:
The skin prevents pathogens from entering our body. It covers almost all parts of our bodies and if we get a cut, the skin will begin to heal itself so no bacteria can get into our bodies and cause infections.
Explanation:
O-H bond is referred to as the most polar.
Explanation:
O-H bond is said to be most polar because the electronegativity is different. Electronegativity can be said as the atom's ability to attract electrons towards itself. Electronegativity of an atom increases when there is a movement on the periodic table from left to right.
When the electronegativity between the atoms are different then it is said to be a polar bond on the other case if the electronegativity between the atoms are same it is said to be non- polar bonds.
Answer:
The lids of the Petri dishes were inadvertently left on while being sterilized
Explanation:
- The process of eliminating any microbe from a particular object to achieve a sterile aseptic environment is termed as sterilization.
- Sterilization mainly aims to either remove, kill or make any microbe inactive by using various means such as irradiation, heat, pressure, etc.
- In the given question radiation is used to sterilize the Petri dishes and thus, if sterilization is successful there should not be any contamination.
- However, since there is contamination present amongst the bacterial colonies growing on agar plated in the Petri dishes this shows that the sterilization has not been done successfully and a possible reason for this could be that while sterilizing the<em> lids of the Petri dishes were kept on. </em>
