Identify the parts used in an electric circuit.
Answer:
Every circuit is comprised of three major components:

a "source" of electrical power, such as a battery or household wall outlet, and,
a "load" that needs electrical power to operate, such as a lamp.

Inhaled air has 0,03% carbon dioxide but exhaled air has 4,1% carbon dioxide. Account for the above difference in the amount of carbon dioxide. Please help.
Answer
C02 is produced in the body.
Explanation:
Every tissue in the body utilize oxygen for its metabolic activities and excrete carbondioxide.Every tissue is supplied by blood. Blood transports oxygen from heart to the tissues used for metabolic activity.Tissue produces carbondioxide as a result of metabolism.Blood transports back carbondioxide from tissues to lungs to expel it out from the body. Inside the lungs, CO2 from blood vessels diffuse into lung tissue (simple diffusion) and then lungs exhale it. That'why there is additional percentage of carbondioxide in the exhaled air.

Answer:
Explanation:
Remark
If you throw something away, you have done nothing to try and make use of it. It's easy, quick and not environmentally friendly.
All the others help the environment.
Reduction means there is less to throw away.
Reuse means that the object gets a new life of usefulness so it is not thrown away. .
Recycle means that that something that would take years to decompose, is done very quickly and hopefully efficiently.
It is throw away because those are the ones which is used

What does band mean in Edwin Drake’s lucky strike
Answer:
Edwin Drake was the first person to strike oil in America. His world-famous well was drilled in Titusville, PA, a small town in Crawford Count
Answer:
Drake met stockholders of the Pennsylvania Rock Oil Company, which claimed a lease on land near Titusville, Pennsylvania, where oil had been gathered from ground-level seepages for medicinal uses. The company hoped to make money selling the oil for lighting, and to this end the stockholders sent Drake to Titusville to assess the viability of the enterprise. Letters of introduction to businessmen in the area referred to Drake as “Colonel,” and for the rest of his life he was known as Colonel Drake. After Drake returned to New Haven with a favourable report, the New Haven stockholders formed a new company, the Seneca Oil Company, sold some stock to Drake, and sent him back to develop the site.
Explanation:
A famous case study in the united states describes how a very polluted lake was able to be remediated and is now used for recreation by many people which lake was this?
A: Lake lanier in Georgia
B: Lake Washington in Washington
C: Lake Tahoe in Devada
D: Lake Apopka in Florida
Lake Tahoe in Devada suffered from a severe eutrophication damage until control and remediation activities were carried out. Option C is correct.
What is eutrophication?
The term eutrophication refers to the biological process produced in water by an oversupply of nutrients or organic matter.
Human pollutive activities are closely related to this artifical eutrophication and, in several cases, are the cause.
Nutrients, mainly compounded with nitrogen or phosphorous, favor phytoplankton multiplication, especially cyanobacteria. Primary productivity enhances due to the sharp increase in these microscopic organisms.
The overgrowth impedes light reach deeper areas, affecting the biota living there. Sedimentation is caused by the death of plants and algae that sink to the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
Both processes, phytoplankton overgrowth on the surface and fermentation on the bottom, originate toxic compounds that damage the animals.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
Decomposition and fermentation processes increase, producing a bad smell.
This whole cycle continues as long as cyanobacteria are present.
Among the main human activities responsible for eutrophication we can mention tourism, agriculture and the cattle industry, and the lack of controlled organic waste treatment.
This what occurred in the Lake Tahoe, in Devada, after the impact caused by tourism, deforestation, and the cattle industry.
This lake suffered from a severe eutrophication damage until control and remediation activities were carried out.
The correct option is C. Lake Tahoe in Devada.
