hope this helps :)
The right matches are:
Ventricular fibrillation ==> Loss of consciousness and death
Two successive PVC's ==> Often asymptomatic
Bizarre ECG waves ==> Defibrillation is needed
.
Ventricular fibrillation is a violent and disordered contraction of muscle fibers, especially the heart muscle, in the ventricles. This systematically leads to loss of consciousness or death.
Defibrillation is a treatment by electrical shock of abnormal contractions of the heart fibers, in order to restore a normal heart rhythm.
Premature contraction of the heart alters the normal heart rhythm but is clinically undetectable or expressed as palpitations.
The answer to your question will be B. The higher our current rate of consumption, the less coal will be available in the future.
Competition killed off all the organisms without traits that were benefitial to them. The organisms in the Galapogos Islands, such as the finches, made adaptions to settle in their new environment.
Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
