The atrioventricular valves.
The chemicals, neurotransmitters are released to carry a nerve impulse which is an electric signal transmitted by the nervous system. This impulse transmitted from one neuron to another. Examples of neurotransmitters are serotonin in which scientists thinks that a low level of this is one of the causes of depression.
Answer:
Plants that adapted to the cooler conditions would survive and rapidly evolve into a new species.
Explanation:
<em>The plants will react by evolving through natural selection.</em>
The plant species that do not have the genes to adapt to the rapid change in climate would become extinct while those with adaptive genes will survive, reproduce, and contribute rapidly to the development of future generations.
In other words, natural selection selects for individuals with adaptive genes and ensures that such individuals reproduce more and give rise to future generations with the adaptive gene while individuals that are poorly adapted to the change in climate gradually fade off the population.
Hence, <u>the plants that adapted to the cooler conditions would survive and rapidly evolve into new species</u>.
It rains, water moves and erodes the land and creates valleys and rivers.
Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments.The Earth's magnetic field is somewhat caused by the composition of the earth's core which is rich in iron minerals. There is a solid inner core that is made of iron which makes up to 2/3 of the moon's size. The charged metal of the iron produces electric currents, consequently resulting to Earth's magnetic field.
