Answer:
This is Mendel's principle of dominance.
Answer:
At brain death.
Explanation:
If an individual is awake but not conscious of what is happening in the surrounding environments the person is in the vegetative state.Such individual could respond to certain reflexes as eye blinking,withdrawal of hands in response to touch, ability to sleep and wake up at normal sensations.However, cognitive functions and sensory responses which are related to emotions are not responded to.It is different from Coma in which the individual lacks ability to be aware of the environments and tom be awake or alert.
The vegetative state ends when brain deaths occurs.This is the state when all brain activities are lost permanently. Breathing seized,and contact with the external world is cut.Thus, the functions of the brain which were supported by artificial supports are lost because the parts of the brain which control breathing,heartbeat ,and blood pressure are dead. Therefore, the life supports can not stimulate them to life
Dendrite
<span>Postsynaptic
membrane is usually found in the dendrite.
Dendrite is the primary site on a neuron for receiving
signals from other neurons and it transmits the signals toward the cell body from
which the dendrite extends from, using short distance graded potentials rather
than action potentials. In a chemical synapse, the postsynaptic membrane receives
a signal from the presynaptic cell and responds through depolarization or hyperpolarization.
The synaptic cleft separates postsynaptic membrane from presynaptic membrane</span>
