Biology

A shared character is one that two lineages have in common. Because organisms evolve from common ancestors and then diversify, the logic is stating that the more shared characteristics two organisms have, the closer their evolutionary relationship is.

olya-2409 [2.1K]

Answer:

Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).

Explanation:

Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.

What describes a result of the greenhouse effect?
dexar [7]
The greenhouse effect occurs when rays enter our atmosphere and are reflected from the ground up. They get changed during their voyage through our atmosphere and they change in such a way that they can't leave the atmosphere anymore. Then they stay inside and heat up the planet which causes thing like global warming. That's what the greenhouse effect is.

Explain the connection between earths magnetic field and iron
german
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.

What is the mystery element? is this a metal, nonmetal, or metalloid?
kiruha [24]

This is a metal!

I believe this is a metal because non-metal can be cut out instantly as this element shown has a metallic luster. Metalloids can be removed as they are worse at the conduction of electricty than metals, and all of the other properties listed are properties held by metals.

(Yes this is just my old answer but only because it is really the same reasoning)

Hope this helps, if not, comment below please!!!
