Physiological factors such as ____________ , water levels, and ph must remain within a certain ____________ for cells and organi
Monica [59]

For an organism to function properly all the physiological factors should be favorable. These physiological factors include water level, pH, temperature etc. To perform the basic function of the life, it is important to maintain the physiological parameter in a particular range.  

In case, these physiological parameters are not balanced, then the body of the organism does not perform well and causes illness.  

So, the first blank can be filled with temperature and the second blank can be filled with range.

In a simple synapse, neurotransmitter chemicals are received by _______. A. the presynaptic membrane B. dendrites C. axon hilloc
artcher [175]

Answer:

In a simple synapse, neurotransmitter chemicals are received by the postsynaptic neuron.

Explanation:

The presynaptic membrane is where neurotransmitters are generated, whereas the postsynaptic membrane is where the neurotransmitter receptors have been located. The axon terminal is substantially far more structurally complicated at a neuromuscular junction.

Axon Hillock performs administrative duties by adding up all incoming signals, including inhibitory and stimulating. The action potential gets activated if this total surpasses the limiting threshold.

The neuron's cell body controls the structure of the neuron, houses its genetic material, and supplies energy for its various functions. Additionally, the dendrites' receiving information is processed by the cell body.

Dendrites gather and retain all data coming from the terminal of the axon. Dendrites get any incoming data or signals from the other neuron.
