Answer:

(A) fossil is the most useful.

It serves as an index fossil. The seashell is a great index fossil because it only appears in the sandstone layer in multiple locations in the same layer of time.

Explanation:

Index fossils are fossils used to define and identify geologic periods. Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.

Answers questions . why are estuaries, such as the pamlico estuary, so important? . how would you be able to determine from whe
GaryK [48]
Estuaries, often reffered to as the nurseries of the sea provide feedind habitats for many aquatic animals and plants. Fish and shellfish commonly eaten in the U.S such as oyesters and Salmon complete almost half of their lifecycles in estuaries. Due to its shallow water,Pamlico estuary especially provides opportunities such as Fishing, crabbing and watersports as well.
We can be able to determine this concept by basing our facts on two concepts. Nutrient Influx, upon reaching the estuarian ecosystem, the nutrients in the presence of sunlight undergoes photosynthesis and produce phytoplanktons. Basically, where there is sunlight, we can assume there is a nutrient influx. Presence of Phytoplanktons will in turn help attract animals such as fish. Also, another contribution of nutrient influx is manure produced by the animals

Sewage treatment plans and fertilizer runoff. Auto emissions of nitrogen, fertilizers applied on golf courses and home gardens can contribute. Some plankton species may produce toxins that might cause these outbreaks

Compare the benefits and environmental impacts of pesticide use.
asambeis [7]

Answer:

<u>Benefits</u>:

pesticides can keep harmful pests–such as rats, mice, ticks and mosquitoes–away from crops while also protecting the plants from weeds and diseases that have the ability to greatly reduce crop yield.

<u>Environmental impacts</u>:

Pesticides may move with runoff as compounds dissolved in the water or attached to soil particles. Runoff from areas treated with pesticides can pollute streams, ponds, lakes, and wells. Pesticide residues in surface water can harm plants and animals and contaminate groundwater.
