Answer:
Letter a) Protists would have less permeable membranes than those in hypotonic or Isotonic environments, wlowing less water to enter the coll. Also, they could possibly develop higher salt concentration within the cell to retain water.
Answer:
Action Potential reaches the Axonal terminal
Vesicles filled with neurotransmitters move to the end of the axonal terminal
Neurotransmitters are released into the synaptic cleft
Neurotransmitters attach to the sodium channels on the dendrite.
Sodium channels open
Sodium moves into the Dendrite
Action potential travels through the dendrite
Explanation:
The process of transmission of action potential across a synapse ( a junction between two neurons) begins with the arrival of an action potential from the presynaptic neuron. The steps are given below:
Action Potential reaches the axonal terminal of the presynaptic neuron
Vesicles filled with neurotransmitters move to the end of the axonal terminal of the presynaptic neuron
Neurotransmitters are released into the synaptic cleft
Neurotransmitters attach to the sodium channels on the dendrite of the postsynaptic neuron
Sodium channels open
Sodium moves into the dendrite of the postsynaptic neuron.
Action potential travels through the dendrite towards an effector or another neuron.
Probably this is through a process known as respiration
Answer:
Centrioles
Explanation:
Centrioles are organelles located near the nucleus that help organize the chromosomes before cell division so each daughter cell receives the correct number of chromosomes.
