Earth was formed over 4.5 billion years ago meaning this world looked completly different from how it looks now. volcanic outgassing most likely created the world (but it's still uncertain). the earth began in the ocean and arose from there. the early atmosphere contained almost no oxygen until later in the years, building up oxygen. The earth contained a diveristy in chemicals.
hope this helps!!
All plants and animals are made up of cells where the genetic material can be found in the form of genes and chromosomes (usually in the nucleus).
Answer:
Astronomers use NASA's Spitzer Infrared Telescope and Chandra X-ray Observatory to see young stars, which emit a lot more high-energy radiation than their older versions.
Explanation:
The two organisms displayed what is known as co-evolution.
<h3>Co-evolution</h3>
It is the reciprocal changes that take place in organisms of different species based on how they interact with each other.
Since yucca flowers and yucca moth change in response to changes in either one of them, they are said to co-evolve.
Co-evolution is a process that takes place gradually, over a long period of time. Without co-evolving, one of the two interacting organisms suffers and may end up going extinct or find another way to adapt.

The correct statement is liver cells possess transcriptional activators that are different from those of lens cells.
<h3>What are Transcriptional activators?</h3>
Transcriptional activators are specific protein sequences capable of activating gene expression.
These transcription factors (transcriptional activators) act to regulate gene expression in target cells.
Transcriptional activators are factors that enable the expression of certain genes in particular cell types.
