Changes in maps of any kind are possible in the future. The probability of a change in a topographic map representation of a mountain in the future increases the further into the future we intend to predict.
Topographic maps are useful to obtain a general overview of the land in a certain area. Among the many things that these maps show the user are:
- Hills
- Ridges
- Valleys
- Lakes
- Rivers
- Creeks
- Trails
- Roads
- Elevation of the ground.
These contents can change based on natural occurrences. In the case of a mountain, natural disasters such as an <em>earthquake</em> or <em>volcanic eruption </em>can drastically change the topography of said mountain. The movement of tectonic plates is also a prime example of how the appearance of a mountain may change in the future.

Choice A is the correct choice, The graduation rate in a city and the rate of unemployment in that same city would not have a positive correlation.
The correct option is D.
Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.
At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.
Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.
Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.
Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.
So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.

Answer:
RNA synthesis proceed in 5' to 3' direction.
Explanation:
The process of formation of RNA molecule from the DNA template is known as transcription. The transcription process is necessary for the gene expression.
The process of RNA synthesis always occur in the 5' to 3' direction. The RNA polymerase moves from the 3' strand and adds the polynucleotide and RNA synthesis in 5' to 3' direction. The anti parallel nature of the nucleotide causes the RNA synthesis in 5' to 3' direction.
