Wetlands are able to remove nutrients and chemicals from water as the water flows through the area. A developer is planning to destroy most of the wetlands near a bay. In three to five sentences, explain how destroying the wetlands would impact the bay’s water quality and ecosystem.
hope this helps
Answer:
Wetlands are from being useless, disease-ridden places, wetlands provide values that no other ecosystem can. These include natural water quality improvement, flood protection, shoreline erosion control, opportunities for recreation and aesthetic appreciation and natural products for our use at no cost. Removal of the wetlands can result in fish disease, dominance of acid-tolerant species, contamination of groundwater, reduction in agricultural productivity and damage to infrastructure through corrosion. The loss of the wetlands introduces invasive species, either intentionally or unintentionally, these species can put pressure on native plants and eventually push them out of their native habitat.

How are the wetlands being destroyed?
In the last three decades alone, nearly one-third of natural wetlands have been lost to urbanization, agriculture expansion, and pollution. The loss of wetlands in urban areas has been more rapid.

How would one convert 15 seconds to hours?
Answer:
A
Explanation:
15 sec * 1 hr/3600 sec (note how 'sec' cancels out and you are left with 'hour' in your answer) = 15/3600 hour
Answer:
answer d
Explanation:
Convert 34.0 mm to inches. Please use dimensional analysis, I know the answer is 1.34in I just don’t know how to get there.
[tex]34.0mm\ x\ \frac{cm}{10mm}\ x\ \frac{in}{2.54cm}[/tex]
put your equation so that your units cancel. The 'mm' will cancel with each other which will get you 'cm' and then the 'cm' will cancel with each other which will get you 'in'.
34.0 millimeters converted to inches would be 1.3385 inches.
What is a unit of measurement?A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.
Any additional quantity of that type can be stated as a multiple of the measurement unit.
Length is one of the most commonly used measurement parameters.
As given in the problem statement we have to convert Convert 34.0 mm to inches by using the dimensional analysis,
As we know that millimeters and inches, both are units of length,
1 millimeter = 0.0393701 inches
34.0 millimeter = 34.0× 0.0393701 inches
= 1.3385 inches
34.0 millimeters converted to inches would be 1.3385 inches.
Thus, 34.0 millimeters converted to inches would be 1.3385 inches.

When would a transformation of chemical energy to electrical energy occur?(1 point)
when the current becomes zero
when a reaction produces the same products
when there is chemical reaction between metals and nonmetals
\
when electrons stop moving between atoms
A transformation of chemical energy to electrical energy occurs when there is a chemical reaction between metals and nonmetals.
What is electrical energy?The movement of electrons from one atom to another is what results in electrical energy.
A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit.
Hence, option C is correct.
