Answer:
Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).
Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.

Answer:
Astronomers have always assumed that Uranus must have been knocked onto its side by a collision. Now a new idea suggests that the planet's remarkable tilt could have another explanation.
Explanation:
I just know it
1 ) under water earthquakes cause a disturbance sending water outwards away from the point of the earthquake due to air and pressure coming into contact at gray force
Greenhouse gasses have increased due to carbon emissions and the amount of fossil fuels that humans are burning and releasing into the atmosphere. These gasses are keeping earths heat trapped, causing global warming/ climate change.
Answer:
Options B and C
Explanation:
Living things can be divided into three domains: archaea, bacteria and eukarya
The domain "eukarya" includes kingdom fungi, plantae, and animalia
A Fungus is any member of the kingdom Fungi. Fungi are eukaryotic organisms typically having chitin cell walls but no chlorophyll or plastids. Fungi may be unicellular or multicellular. Examples of fungi are mushroom, yeast, mucor etc
Plants are multicellular eukaryotic organisms that have double-membraned chloroplasts in its cells containing chlorophyll.
Animals are multicellular organisms that is usually mobile, whose cells are not encased in a rigid cell wall (distinguishing it from plants and fungi) and which derives energy solely from the consumption of other organisms (distinguishing it from plants).
