Answer:

The answer is B. A cell is the basic structural and functional unit of living organisms.

Explanation:

Cell theory is a fundamental part of biology that explains the constitution of living matter based on the cell and the role they play in the constitution of life. This theory specifies how cells are fundamental and important for the existence of life and how they determine the most important characteristics of living beings.

coldgirl [10]
Depositional processes along coastlines, such as sediment transport, form sandy beaches and create highly complex landforms that experience constant change and movement. Features such as spits, barrier islands, tombolos, and dunes are classic forms in sandy beach environments.

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect
kolezko [41]

Complete question:

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?

A.  Slow effector pathways

B.  Modulated effector pathways

C.  Rapid effector pathways

D.  NMDA glutamate receptor pathways

Answer:

D.  NMDA glutamate receptor pathways

Explanation:

The NMDA glutamatergic receptor is a cationic channel receptor modulated by a ligand that allows the transport of Na+, K+, and Ca2+. Under certain situations, it exhibits particular permeability to Ca2+. The receptor has different regions that are susceptible to modulation by endogenous and exogenous agents. The receptor can be found at most excitatory synapses, where it responds to the neurotransmitter glutamate. During synapsis, the presynaptic membrane releases L-glutamate, which is received by NMDA glutamatergic receptor. The receptor plays a regulatory role because activates signaling cascades that depend on calcium.

These receptors are involved in normal synaptic transmission, in a diverse physiological phenomenon, and might be responsible for neurodegenerative processes.

Alan observed that a lot of soil from his garden swept off from after heavy rain. Which is this process called?
dolphi86 [110]
D.) Is the most sensible answer.

Explanation: I used the process of elimination to solve this. Groundwater recharge sounds too far off of the topic, snow melt is...well...melting snow, infiltration also has nothing to do with the subject, but surface runoff is the only one that makes sense, is on topic, and seems to have a meaning similar to the occurrences describes in your question.
