Answer:
The correct answer is option C. "disruptive selection".
Explanation:
Disruptive selection is a type of natural selection at which extreme values for a trait are favored, while intermediate traits are more likely to disappear. In this example the finches tended to have either small beaks or large beaks because small beaks are best at eating soft seeds and large beaks are best at cracking seeds. This is an example of disruptive selection because the two extreme values for the size of beaks are favored.
Answer:
Since some fish eat algae likely an algae bloom will occur.
Explanation:
Harmful algal blooms (HABs) occur when algae — simple photosynthetic organisms that live in the sea and freshwater — grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. This can have a detrimental impact and it looks disgusting. It would most likely kill off the marine life in that area.
They would use a microscope to test it out.
Answer:
a mycorrhiza
Explanation:
Mycorrhizae are mutualistic associations that occur between fungi and the roots of most vascular plants, which are those that have sap-carrying vessels.
Fungi increase the nutrient absorption capacity of plants while providing sugars and amino acids essential for the existence of fungi. That is, both (fungi and plants) are mutually beneficial. This is because fungi nourish plants and they, in turn, during photosynthesis produce carbohydrates that are assimilated by the fungi.
Mycorrhizae absorb nutrients from the soil and transmit them to plants. In this way, plants absorb water and mineral salts more easily and are therefore able to develop better and resist disease as well as climate change.
