Neurons contain which can receive signals from other neurons.
axons
mitochondria
dendrites
golgi bodies

The correct answer is C. Dendrites

Explanation:

A neuron is a type of cell that plays an important role in the brain and nervous system as these are the basic unit in these organs and the ones that transmit information. In terms of structure, neurons are composed of the soma, dendrites, axon and the synapses. The soma is the main body of the neuron, the axon is a structure in charge of conducting electrical impulses, the synapse is a structural connection between neurons and the dendrites are the connection that allows neurons to transmit and receive messages between them. Considering this, it can be concluded dendrites are the ones that can receive signals or messages from other neurons.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
