Answer:

Despite the availability of cleaner energy sources, most of the energy used to power American homes comes from the

burning of fossil fuels such as coal and oil. The burning of fossil fuels releases carbon dioxide into the air. Carbon dioxide

is a greenhouse gas that contributes to climate change.

Why do you think it's a challenge to reduce fossil fuel usage in homes in the United States? How could the use of fossil

fuels affect the biodiversity in neighborhoods and the surrounding ecosystems?

West of mississippi river totaled 5.4 MMst

The supply of both types of coal is expected to decline as production from Appalachia falls from 201.5 million tons in 2018 to 170.1 million tons in 2020.

Ronch [10]

Answer:

The heart has an intrinsic conduction system that causes electrical activity in the heart muscles causing them to contract. The intrinsic conduction system is made up specialized cells, that contain nerve and muscular characteristics.
The muscle cells in the heart are linked together by gap junctions, allowing cardiac action potentials to travel from one muscle cell to another.
Atrioventricular (AV) node. The damage to the AV node causes the electrical signals traveling from the upper chambers to the lower chambers to be impaired causing an AV block.

A patient breaks a leg. predict which model a doctor will use to show where the break is

VMariaS [17]

A doctor can use a 2D image model to show where the break is.

When a patient breaks a leg (the break could be as a result of fracture or bone dislocation), the doctor needs to scan the patient in order to determine the exact location of the break and the extent of the injury.

The gamma camera, x-ray machine and PET scanners are some of the devices that can be used to scan a bone.

Each of these devices uses 2D image technology to show the result of the scan.

So, a model that can be used by a doctor to determine the location of the break is 2D image.
