True in most cases unless they erode then the younger ones will be on top
Answer:
Environmental impacts of particles, such as dust and smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem
Environmental impacts of greenhouse gases released from livestock production - increase in atmospheric temperature
Explanation:
Environmental impacts of particles, such as dust and smoke, released from livestock production -
Release of particles such as dust and smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.
These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.
Environmental impacts of greenhouse gases released from livestock production -
Green house gases will lead to increase in atmospheric temperature
Answer:
The minimum mass of dissolved cholesterol that the new system must be able to detect is 0.43 milligrams.
Note: The question is incomplete. The complete question is:
<em>GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect borderline high levels of dissolved cholesterol (170, to 200. mg/dL), using a blood sample that is as small as 250 μL Calculate the minimum mass in milligrams of cholesterol that the new system must be able to detect Be sure your answer has the correct number of significant digits.</em>
Explanation:
Range of the equipment to detect cholesterol in blood = 170.0 to 200.0 mg/dL
Minimum amount of cholesterol that can be detected by instrument = 170 mg/dL
Volume of blood sample = 250 <em>μ</em>L= 0.0025 dL (1 dL = 100000 <em>μL)</em>
Amount of dissolved cholesterol in 250 <em>μL</em> sample of blood =
170 mg/dL * 0.0025 dL = 0.425 mg
The minimum mass of cholesterol that the new system must be able to detect is 0.43 milligrams.
A reverse reaction is the chemical reaction moving both forward and backwards.
An example of this is Ammonium chloride ⇌ ammonia + hydrogen chloride
This is a symbol for reverse reaction ⇌
