which factor(s) are hypothesized as the causes of the triassic-jurassic mass extinction? check all that apply.

Answers

Researchers debate theories about the Triassic-Jurassic extinction event's origins, which include climate change, asteroid impacts, and volcanic eruptions.

The Triassic and Jurassic mass extinctions: what happened?

The end-Triassic extinction was brought about by massive and extensive volcanic eruptions. Around 200 million years ago, an increase in atmospheric CO2 led to the oceans becoming more acidic and the Earth being warmer, which contributed to the extinction of 76% of marine and terrestrial species.

Which are the top 4 reasons for mass extinctions?

Extreme temperature variations, fluctuating sea levels, and catastrophic, one-time occurrences like a supervolcano erupting or an asteroid impacting Earth have all been responsible for previous mass extinctions. We are aware of them because the fossil record demonstrates how life has altered over time.

Which of the following is the BEST explanation of the role of DNA and RNA in making proteins?

A. DNA unwinds into two separate strands, and a complementary copy of each is produced during replication. During transcription, a DNA strand is used to produce a complementary strand of mRNA, with uracil taking the place of thymine. During translation, each set of three bases in the mRNA results in an amino acid being added to a chain, and a protein is formed.
B. DNA unwinds into two separate strands, and an exact copy of each is produced during replication. During transcription, a DNA strand is copied to produce mRNA, which is an exact copy of the DNA strand except that uracil takes the place of thymine. During translation, each set of three bases in the mRNA results in a protein with a specialized function being formed.
C. DNA unwinds into two separate strands, and a complementary copy of each is produced during replication. During transcription, a DNA strand is used to produce a complementary strand of mRNA, with uracil taking the place of adenine. During translation, each base in the mRNA results in an amino acid being added to a chain, and a protein is formed.
D. DNA unwinds into two separate strands, and an exact copy of each is produced during replication. During translation, a DNA strand is used to produce a complementary strand of mRNA, with uracil taking the place of thymine.
