One of the reasons you might struggle to lift a heavy object with your arm fully extended is because:_______.
klasskru [66]

Answer:

the overlapping decreases between the thin and thick filaments.

Explanation:

When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.

Define brain death, agonal phase, clinical death and mortality.
OleMash [197]
  • Brain death: is the legal definition of death. It is the complete and irreversible stop of all brain functions. This means that as a result of severe aggression or severe brain injury, the blood that comes from the body and supplies the brain is blocked and the brain dies.
  • Agonal phase: occurs with the realization of the preceding events when life is about to break free of the protoplasm, because the protoplasm cannot sustain it for long.
  • Clinical death: is defined by the cessation of electrical activity in the brain, resulting in irreversible and total loss of neurological activity in the brain and brainstem. When doctors officially declare a person's clinical death, it means there is no cure or return to recovery.
  • Mortality: It is the condition of being mortal, therefore, of being susceptible to death. However, the term mortality is in most cases related to the statistical studies applied on populations. So mortality appears as a number that seeks to establish the number of deaths over a given population.
