What type of channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters?.
Voltage-gated Ca²⁺ (calcium) channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters.
Voltage-gated calcium channels open in response to the wave of depolarization brought on by the action potential at the axon terminal. Neurotransmitter-containing synaptic vesicles undergo exocytosis when calcium reaches the axon terminal, releasing its contents into the synaptic cleft.
Action potentials are formed when a neuron gets stimulated causing a local depolarization in the cell membrane. This local depolarization triggers adjacent areas of the cell membrane to depolarize, and this continues creating a wave of depolarization traveling in one direction down the axon, called an action potential. As the action potential arrives at the axon terminal, specialized channels allow for the propagation of the action potential across the synaptic cleft to the adjacent neuron.

In the structure of the neuron, the __________ receives messages from other cells.
The correct answer is Dendrite.
A useful analogy is to think of neurons as trees. Neurons consist of three main parts: dendrites, axons, and cell bodies or cell bodies (see diagram below), which can be represented as branches, roots, and trunks of a tree, respectively. Dendrites (branch) are where neurons receive input from other cells. The dendrites branch like branches toward the tip and even have leaf-like structures called spines.
Axons (tree roots) are the starting structures of neurons. When a neuron wants to talk to another neuron, it sends an electrical message, called an action potential, across the axon. The cell body (tree trunk) contains the nucleus, houses the neuronal DNA, and makes proteins for transport down the axons and dendrites. Both the brain and spinal cord have different types of neurons. They are generally classified based on where they originate, what they project to, and what neurotransmitters they use.

A serious environmental hazard, acid mine drainage is the result of chemical weathering of pyrite that yields ________ and ________ that will degrade aquatic habitats.
A serious environmental hazard, acid mine drainage is the result of the chemical weathering of pyrite that yields sulfuric acid and iron oxide that will degrade aquatic habitats.
Mine drainage is created when pyrite, an iron sulfide, starts reacting with air and water to produce sulfuric acid and iron oxide.
Both of these chemicals are released into the water and pollute the aquatic bodies.
The increasing amount of sulfuric acid and iron oxide is affecting aquatic and marine life badly.

How many moles of electrons are required for a denitrifying organism to reduce 36 moles of nitrate (no3-) to dinitrogen gas (n2)?
180 moles of electrons are required for a denitrifying organism to reduce 36 moles of nitrate (no3-) to dinitrogen gas (n2).
The reaction of denitrification is:2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O
From the above equation:2 moles of nitrate = 10 moles of electrons36 moles of nitrate = 36×2/10 = 180 moles of electronsNitrate and nitrite are converted to gaseous forms of nitrogen, mostly nitrous oxide (N2O) and nitrogen, through the microbial process of denitrification (N2). Numerous microorganisms have the ability to denitrify. When the oxygen (O2) level in their immediate environment changes, denitrification occurs.The entire conversion of nitrate to molecular nitrogen often involves a number of bacterial species, and more than one enzyme pathway has been found in the reduction process.Complete denitrification has an impact on the environment because nitric oxide and nitrous oxide, two intermediates in the process, are important greenhouse gases that combine with sunlight and ozone to form nitric acid, a component of acid rain.Therefore, the correct answer is 180 moles.
