Kiara pours measures the mass and volume of four mystery liquids and pours them into a beaker the liquids separate into different layers according to Kiara's data above, which liquid would make up the bottom layer of the beaker?

red will be the bottom layer

Explanation:

in order to find its density you have to do mass/volume.

Blue: 12/3 = 3  

Clear: 10/5= 2

Red: 15/3= 5

Yellow: 18/9 = 2

The one with the greates valua aka greatest density will be at the bottom layer/

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
