Answer:
The external coverings of diatoms are made up <u>silica </u>, while slime molds have cell walls containing <u>cellulose.</u> Diatoms are <u>photoautotrophs</u> because they make food through photosynthesis, while slime molds are <u>heterotrophs</u>.
Explanation:
Diatoms can be described as algae that are mostly single-celled. They are made up of a unique kind of cell wall composed of silica. This cell wall is termed as a frustule. Mostly, diatoms are capable of carrying out photosynthesis and hence make their own food.
Slime moulds can be described as organisms that are fungus-like protists. They are not capable of producing their own food and feed on other plants. Hence, they are heterotrophs.
Answer:
Coral reef fish are a significant food source for over a billion people worldwide. Many coastal and island communities depend on coral reef fisheries for their economic, social, and cultural benefits. But too much of a good thing can be bad for coral reefs.

Coral reef ecosystems support important commercial, recreational, and subsistence fishery resources in the U.S and its territories. Fishing also plays a central social and cultural role in many island and coastal communities, where it is often a critical source of food and income.
The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations. Such losses often have a ripple effect, not just on the coral reef ecosystems themselves, but also on the local economies that depend on them. Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats.
Coral reef fisheries, though often relatively small in scale, may have disproportionately large impacts on the ecosystem if conducted unsustainably. Rapid human population growth, increased demand, use of more efficient fishery technologies, and inadequate management and enforcement have led to the depletion of key reef species and habitat damage in many locations.
Answer:
Mg is a reactant ,H2 is a product, MgCl2 is a product and HCl is a reactant.
Answer:
1. "a, O, and J"
2. "R and C"
3. I'm not entirely sure about #3, but I believe the answer is "d and R"
4."J, K, I, M, N"
5. "d"
6. "I" explain why: "It is at the bottom, so it is therefore the oldest."
7. "Q" explain why: "It is at the top, so it is therefore the youngest."
8. The folding occured before the faulting. Why? Because the folding is evident in the second half of the fault.

Answer:
The Dense supportive barrier is the cell wall that prevents the bursting of the vacuole. If the plant is wilting, that means it cannot maintain turgidity. Therefore, the cell wall has been damaged.
