What are examples of pollution that can be caused by agriculture?
Answers
Answer:
Nitrate from agriculture is now the most common chemical contaminant in the world’s groundwater aquifers. Aquatic ecosystems are affected by agricultural pollution; for example, eutrophication caused by the accumulation of nutrients in lakes and coastal waters impacts biodiversity and fisheries.
Answer: Agricultural Pollution is a waste or discharge resulting from farming that degrades or contaminates the surrounding environment. This pollutions comes from several sources and has adverse effects on many different types of organisms. The impact of this pollution can be reduced through certain practices. Causes are:
Explanation:
Pesticides and Fertilizers. To begin with, the earliest source of pollution has been pesticides and fertilizers. ...
Contaminated Water. ...

[tex]\boxed {\boxed {\sf Choice \ B }}[/tex]
Explanation:
First, let's think about what a greenhouse is. It's a building made of glass that plants grow in. The glass traps heat, so the plants can continue to grow, even in the cold and harsh winter months.
The Greenhouse Effect is like that, but on a much greater scale.: planet Earth! Gas particles, infamously carbon dioxide and methane, trap the heat. The sun heats up our planet during the day and it cools at night. The heat goes back into space, but some is trapped by the gases.
This is why many scientists are concerned about global warming. They worry that burning fossil fuels releases carbon dioxide, which traps heat and warm the planet.
So, based on what we learned about the greenhouse effect, choice B is correct.
a
a decrease in the number of zebra mussels along the waterways
b
an increase in the number of zebra mussels along the waterways
c
no effect because more time is needed to determine an outcome
d
no change in the number of zebra mussels infecting the waterways

How does this evidence help explain why the skin cancer rate is higher in Australia than in Brazil, even though the two countries get the same amount of sunlight?
Answers
Answer:
The Ozone layer
Explanation:
Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.

In an exothermic reaction, chemical energy is converted to _____.
1.thermal
2. mechanical
Answers
Because exothermic is having to do with energy
The chemical reactions are generally of many types. The exothermic and endothermic reactions are important among them. In an exothermic reaction the chemical energy is converted to thermal energy. The correct option is 1.
What is exothermic reaction?The chemical reactions which proceed with the evolution of heat energy are defined as the exothermic reactions. The chemical reactions which proceed with the absorption of heat energy are called endothermic reactions.
In an exothermic reaction, system loses heat to surroundings. Since heat is given out in exothermic reactions, the enthalpy of the products will be less than that of the reactants.
In exothermic reaction, q will be negative and the enthalpy change will be also negative. In this reaction chemical bonds are broken and new bonds are formed. The chemical energy is converted to kinetic energy which is released as heat.
Thus exothermic reaction releases thermal energy.
