Impulses must travel from neuron to neuron and neuron to muscle cell in an uninterrupted chain, so that all the important messages necessary for survival are properly conveyed. how are impulses transferred from a neuron cell to its receiving cell? an electrical impulse travels down the axon of a neuron and is transferred to the receiving neuron through the release of neurotransmitters. an electrical impulse travels down the axon of neuron and “jumps” across the synapse by propelling the electricity across the space. an electrical impulse travels down the axon of a neuron and ends when it reaches the synapse. an electrical impulse travels down the axon of one neuron and is transferred to a receiving cell through direct contact. none of the above answer choices is correct.

c. movement because i took the test and it lets me review my answers

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
