Fossilized evidence of Earth's first forms of life would consist of?
The earliest fossils known are in the form of stromatolites formed by cyanobacteria about 3.5 billion years ago. To say however that these are the first life forms is not likely to be correct. Cyanobacteria are already a relatively complex single celled organism. It is likely that simpler forms preceded them but so far no evidence of this has been found.
How the fossil record indicates a long history of changing life forms.?
The fossil record shows that different species have evolved over time. The fossil record also provides evidence of how a specific organism evolved from earlier species. The fossil record shows that organisms have become more complex over time. It also shows which organisms lived during the same time period, which have a common ancestor, and which have become extinct.
What thing comes in rechargeable and disposable varieties?
Batteries come in rechargeable and disposable forms.
What is the organic state theory?

Why do the lower levels of sedimentary rock on Earth show fossils of the simplest life forms?
The lower the level of a rock stratum, the older it is. Evolution is recorded in the sedimentary rock record, therefore, the simpler forms would show up in the oldest layers. The old life forms were usually very simple so the deeper down the sedimentary levels are, the older the fossils are their.
According to the theories of complex forms of life evolved over long periods of time from?
charles darwin
What do fungi change complex food into?
Simpler forms that they can absorb. By releasing enzymes to do this.
A series of fossils shows how mammals evolved from what?
Less complex life forms.
Are fossils found in the lowest geological strata generally primitive?
Yes, fossils found in the lowest geological strata are generally more primitive compared to those found in higher strata. This is because the lower strata represent earlier geological time periods when simpler life forms existed, while more complex life forms evolved and appeared in higher strata over time.
How do fungi change complex food into simpler forms they can use?
Fungi give off enzymes that break down complex foods.
What are some precambrian plants?
During the Precambrian period, there were no plants as we know them today. The Precambrian period mainly featured simpler life forms like algae and cyanobacteria. It was not until the Paleozoic era that plant life diversified and evolved into more complex forms.
The process by which food substances are chemically changed into simpler forms that can be absorbed is called?
The process by which food substances are chemically changed into simpler forms that can be absorbed is called digestion. This process involves the breakdown of complex molecules into smaller molecules that can be transported and utilized by the body for energy and nutrition.
How do fungi change complex food into simpler forms they can absorb?
They give off enzymes that break down complex foods. (novanet)
Why is the evolution of the ribosome problematic?
The evolution of the ribosome is problematic because of its complex structure and function. Understanding how such a sophisticated molecular machine evolved from simpler precursors is challenging due to the lack of intermediate forms in the evolutionary record. It also involves intricate interactions between proteins and RNA, making it difficult to trace its evolutionary history.
Why does your body have to digest food?
The food that we eat it in complex forms. Hence we need to break down the complex nutrients to simpler ones so that they can be absorbed by our body. Finally this stored food reacts with oxygen to provide energy.
When was first complex organisms?
Complex organisms first evolved around 600 million years ago during the Ediacaran period. These organisms were simple multicellular creatures that eventually led to the more diverse and complex life forms we see today.
What type of reaction does a complex substance break down into two or more simpler substances?
A complex substance breaking down into two or more simpler substances is typically a decomposition reaction. In these reactions, one reactant breaks apart into multiple products through various processes, such as heat, light, or the presence of a catalyst.
