Certain mental problems are thought to be caused by not having enough
neurotransmitters. Why would a lack of neurotransmitters cause problems?
A. Neurons would not be able to receive sensory messages.
B. Neurotransmitters send signals from neuron to neuron.
C. Neurons would not be able to grow longer.
D. Neurons would not be able to move to new areas.
Answer:
B. Neurotransmitters send signals from neuron to neuron.
Explanation:
Lack of neurotransmitters may cause problems because neurotransmitters send signals from neuron to neuron.
The lack of neurotransmitters cause problems because neurotransmitters send signals from neuron to neuron. Therefore, option (B) is correct.
A neurotransmitter is a molecule that a neuron secretes to influence another cell at a synapse. Another neuron, a gland or muscle cell, or the target cell, could be the cell that receives the signal.
Your body cannot function without chemical messengers called neurotransmitters. Chemical signals, or "messages," are carried from one neuron (a nerve cell) to the next target cell by them. The following objective cell can be another nerve cell, a muscle cell or an organ.

Main features of Solar System, Main facts of solar system
Answer:
The main features of the solar system:
The Sun is our nearest star.
The planets orbit the Sun.
The time taken to orbit the Sun increases with distance from the Sun.
Gravity keeps the planets in orbit around the Sun and the moons in orbit around their planets.
From the Sun, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. You might need to be able to recall this in the exam.
The planets go around the Sun in slightly squashed circular elliptical orbits.
Pluto is classified as a dwarf planet or planetoid. It has a highly elliptical or eccentric orbit.

In Respiration, to where is the energy from sugar molecules transferred?
Explanation:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Answer:
its transferred to ATP
Explanation:
during respiration glucose and oxygen is converted into carbon dioxide and water, so the energy is transferrred to ATP

limestone can be a very jointed type of rock. which drainage pattern would you expect to see as a result
The drainage pattern one is expected to see in the limestone is trellis. The correct option is C.
What are trellis drainage pattern?Trellis drainage patterns form when sedimentary rocks like limestone are rolled up or slanted and then stripped away to varying degrees depending on their strength.
The Rocky Mountains of British Columbia and Alberta are prime examples of this, with trellis patterns found in many of the drainage systems.

Does grain size determine the porosity of a sediment type?
Answer:
Yes
Explanation:
In sediments or sedimentary rocks the porosity depends on grain size, the shapes of the grains, and the degree of sorting, and the degree of cementation. Well-rounded coarse-grained sediments usually have higher porosity than fine-grained sediments, because the grains do not fit together well

Which type of tectonic plate interaction forms a mid ocean ridge?
Answer:
Divergent plate
Explanation:
A semi ocean ridge is formed by the interaction of divergent boundaries. Around divergent plate boundaries, as additional sea floor is formed as the Earth's tectonic plates expand outward, half ridges form. Igneous material grows to the ocean bottom when the plates split, resulting in massive basalt volcanic activity.
