__________ is the situation when one hormone exaggerates the effects of another hormone at the target cell?.
Naily [24]

A situation in which a hormone exaggerates the effects of another hormone at the target cell is called: synergism.

<h3>What is synergism?</h3>

Synergism can be defined as a biological process that typically occurs when two or more hormones produces the same effects of another hormone at the target cell and their combined effects are exaggerated.

Consequently, each of these hormone would act independently of another hormone while having the same effect on the target cell during the synergism of hormones.

Explain what maria and craters are and how they formed. best answer will be marked as brainlest plz help. with an honest answer
kolbaska11 [484]
Lunar maria (plural form of the Latin word mare, which means sea) are dark surfaces that can be found all over the moon (17% of the Moon is covered in them) that have been created as a result of volcanic eruptions. These areas are made up of basalt, and given that they seemed almost waterlike, the astronomers in the distant past mistook them for seas, whence their name comes.
When it comes to craters, their origin is quite similar - volcanic eruptions created them. When lava starts erupting from a volcano, it has to get out from somewhere - and thus craters are created. If you are referring to lunar craters, however, there are many speculations as to how they were created: due to volcanic eruptions, meteoric impact, or glacier activity.
