Answer:
Retrovirus
Explanation:
Reverse transcriptase is a type of enzyme which is present in many RNA based viruses such as retrovirus that are found in humans. Reterovirus uses reverse transcriptase enzyme in order to change their single stranded DNA into double stranded DNA. The process of such type of conversion is called reverse transcription. In viruses such as reterovirus, reverse transcriptase allows the virus to insert its DNA to the host cell's DNA, which helps the virus to produce more viruses.
During mitosis, the chromatin in the nucleus of a cell condenses and becomes visible under a microscope. The membrane around the nucleus breaks down.
Clay minerals and quartz these two are most common detrital sedimentary rocks
Answer:
Explanation:
Darwin's use of many different fields of study including geology, economics, and biology was incredibly important as it allowed him to make connections between them that ultimately led to ground breaking discovery. Such as animals that that migrated to different areas and were interconnected through their geological footprints that were left behind.
