Which blood type can be transfused into a patient who has blood type A–?
Oksana_A [137]

For a person with blood type A- (A negative),  they can be transfused with either  blood type A negative  , or blood type O negative.

This is because any other blood type will immediately be rejected by their body.

A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against  any other blood type of a different group such as B and AB, even if they are  rhesus negative.

Therefore because of the rhesus negative factor, a person with blood type A negative  can only be transfused with rhesus negative .

Which of the following does NOT accurately state a transfer of carbon in the carbon cycle?
Doss [256]

Answer:

The point that does NOT accurately indicate a carbon transfer in the carbon cycle is that burning of wood and debris pulls carbon from the atmosphere to use as energy.

Explanation:

The carbon cycle involves the journey that carbon makes between living organisms and their surrounding environment, i.e. the entire biosphere, geosphere, hydrosphere and atmosphere, and is therefore considered a biogeochemical cycle.

In living organisms, inorganic carbon is taken up by plants to make organic molecules, which will be used by animals - which release CO₂ into the atmosphere - or dead organic matter provides carbon to the soil.

The combustion of wood and debris involves the oxidation of a combustible material -which requires oxygen from atmosphere- to then release CO₂ as a product. So it is incorrect to say that burning of wood and debris pulls carbon from the atmosphere to use as energy.
