Answer:
I think this is 2 because there would have been bigger predators in the ocean vs. a lake
Halophilic bacteria possess a pigment related to the plant's chlorophyll.
<h3>Halophilic bacteria</h3>
They are bacteria that live in high salt environments. They have a certain feature that enables them to pump out salts in order to maintain normal osmotic conditions in their bodies.
Halophilic bacteria are equipped with bacteriorhodopsin and halorhodopsin. These enable them to photosynthesize like plants. and generate the much-needed ATP for pumping out salts.

The Cambrian explosion was a period at the Pre-Cambrian boundary of the geologic time scale at 542 Ma. At this boundary, the fossil record shows that animals suddenly appeared in a dramatic radiation of life. A radiation is the relatively rapid development of new types of organisms that derive from a common ancestor. The Cambrian explosion is important because it marks the origination of all major animal groups called phyla.
Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.
Explanation:
DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.
A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.
The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.
Answer:
I believe it's d... or b
Explanation:
So I'm pretty confident that it's D seeing how it substitutes or deletes but it's only ONE gene...
