Question 10: True Question 11: Competition and Variation
Explanation:
Natural Selection is when the animal with the best survival rates gets the right to mate. Every species wants to survive and by letting the animals with the best traits reproduce, it ensures their survival. This, of course, happens naturally.
Competition is to show whose fit and whose not and variation increases the chance of their survival. For example, if a whole species was exactly the same if one died of a disease then all of them would, because they would have the same immune system. But if there is variation, one might be vulnerable to the disease but the other might have protection from it. Meaning it could pass those genes to offspring because it was fit.

The root nodules of leguminous plants houses nitrogen-fixing bacteria called Rhizobia. Rhizobia has a symbiotic relationship with leguminous plants that allows both to benefit from each other.
By binding to hydrogen, the Rhizobia bacterium is able to convert or fix nitrogen gas into ammonia , a form that the plant can use. Likewise, the legume plant provides the rhizobia bacterium with carbohydrate which the rhizobia depends on for energy. It is important to note that the carbohydrate sent to the nodules for the rhizobia is also what is used as a source of hydrogen to help the bacterium convert nitrogen to ammonia.
Answer:
Water could not convert from precipitation to evaporation I think
Explanation:
Due to their immense oxygen needs, slow-twitch fibers are associated with many blood vessels, mitochondria, and increased concentrations of myoglobin, an oxygen-binding protein in the blood that provides muscles their reddish coloring.
