How is precambrian time different from other divisions of the geologic time scale?
Precambrian time is different from other divisions of the geologic time scale as the life forms in this time had soft bodies.
What are geologic time?Geologic time is the time that is begins at the start of the Archean eon and it is the extensive interval of time occupied by the geologic history of the earth.
Precambrian time is the the earliest time of the geologic ages, which are marked by different layers of sedimentary rock including the fossilized remains of plants and animals buried when the sediments were formed. Main difference between both the times is in Precambrian time life-forms had soft body parts and in Geologic time life-forms had hard body parts.
Hence main difference is of life forms.

Which of the following organisms evolved after amphibians?
Only cats
Only reptiles
Only marsupials and cats
Reptiles, marsupials, dogs, and cats
Answer:
Reptiles, marsupials, dogs, and cats
Explanation:
The correct answer is only reptiles as they evolved after amphibians.
Amphibians were one of the earliest groups of land-dwelling vertebrates to evolve. After amphibians, reptiles emerged. Reptiles are a diverse group of cold-blooded vertebrates that includes animals such as lizards, snakes, turtles, and crocodiles. They have adapted to a wide range of environments, including deserts, forests, and oceans.
The other options provided in the question, such as cats, marsupials, and dogs, did not evolve after amphibians. Cats and dogs belong to the mammal group, which evolved much later than amphibians. Marsupials, on the other hand, are a group of mammals that includes animals like kangaroos and koalas. While marsupials did evolve after amphibians, the question specifically asks for organisms that evolved "after amphibians," excluding any other groups that may have evolved concurrently.
So, the correct answer is "Only reptiles" because reptiles evolved after amphibians.
