True is the correct answer.
Marsupials are pest put some are not but some of them are mammals and some of them are not. I guessed it should be either way .
The order in which the earliest organisms evolved -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
On the earth, various kinds of organisms evolve at different geological times, and on their evolution, they consider the oldest or youngest organisms:
- Archaebacteria and bacteria was the oldest living organism on earth was, they lacked a membrane-bound nucleus and cell.
- The protists evolved after the bacteria, they were multicellular prokaryotic organisms.
- Fungi and the shell-less invertebrate, much-developed organisms in terms of body organization and structure. These have membrane-bound, well-defined cell membranes, and a nucleus. They even had a tissue level of organization.
- Green algae evolve after protists which belong to the division Thallophyta of the plant kingdom. These are photosynthetic as they have chlorophyll in the cell.
- Shelled Invertebrates are the youngest organisms that evolved recently among these.
Thus, the correct order is -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates

<u>ANSWER:</u>
Cosmic background radiation is leftover thermal energy from the Big Bang best describes the origin and expansion of the universe.
<u>EXPLANATION:</u>
- The "Big Bang Theory" is used to describe how the universe has begun.
- The theory basically states that the "universe" began as a "single point" and then "expanded and stretched" and is expanding even today.
- When the universe began, it was "hot tiny particles" mixed with heat and light and as it "expanded" and took up "more space", it cooled down and formed atoms.
- The "best evidence of the big bang" is the radiation of cosmic background that was leftover when the first big bang explosion took place and began the universe.
