Answer:

Coal

Explanation:

Climate change is coal's most serious, long-term, global impact. Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits. Let us look at the quantity of carbonoxide coal plant  emits. For example, coal with a carbon content of 78 percent and a heating value of 14,000 Btu per pound emits about 204.3 pounds of carbon dioxide per million Btu when completely burned. Complete combustion of 1 short ton (2,000 pounds) of this coal will generate about 5,720 pounds (2.86 short tons) of carbon dioxide. This is one of the major reason it should Mr stopped.

The stretch reflex in a skeletal muscle is initiated because of nerve impulses arising from an organ embedded in the muscle call
labwork [276]

Answer:

Muscle spindles

Explanation:

Muscle spindles are stretch receptors thst has both the sensory abd motor components ĺocated in the body of a muscle that basically signals on alterations in the muscle length. They transfer the length information to the central nervous system through the afferent nerve fibers. It fasten the motor neurons through the stretch reflex to prevent muscle stretch. Muscle spindles are sensory receptors that are majorly found in the muscle.

1. What might cause an increase or decrease of carbon dioxide in a given location such as in the atmosphere or buried under grou
AVprozaik [17]

1. The carbon-dioxide increases in atmosphere by fossil-fuels, decaying-dead, automobiles etc. and when animals or plant die they get buried and carbon content increases under the ground.

2. Greenhouse gas are those gases which trap heat in the atmosphere and maintain the temperature of the earth.

3. Diamond and graphite are solid forms of carbon.

4. Dry ice is the carbon as liquid.

5. Autotrophs make simple sugar glucose via photosynthesis and this sugar is used by heterotrophs as a substrate for respiration in the presence of oxygen.

Explanation:

When the fuels from automobiles, fossil-fuel, dead decaying organism release carbon in the atmosphere, the increase in carbon dioxide is the cause of global warming.

Greenhouse gases absorb the infrared radiations from the earth's surface and reradiate it back to the atmosphere. In short greenhouse gases allow sun's rays to pass through and maintain the earth's temperature otherwise the earth will become too cold to sustain lives.

Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type
MakcuM [25]

Answer:

Mrs Jones Blood type= B type.

Safe transfusion from: B and O blood type.

Explanation:

In the given example, the anti-B antibodies are present in the donor plasma.  Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".  

Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.  

She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.
