Im not 100% sure but the best answer I can give is Prokaryotes because they came to be around the time oxygen did as well.
Mitochondria are specilized structures unique to the cells of animals, plants and fungi, they serve as batteries for parts of the cell
Ribosomes are the things that process proteins in the cell for the body
Cytoplasm is the semi fluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane
Cells are a fundamental structural unit of living matter
Tissue makes the difference between cells and complete organs, they hold the shape of the cell
An organelle is a tiny cellular structure that performs specific functions within a cell.
An organ is a group of tissues with similar functions
The answer is 4. Mitochondria
Answer:
formed of ice, rock, and dust
develop tails near the Sun
Explanation:
Comet is a smaller celestial body which is mainly composed of ice and dust.
The other components of this comet are rocks and gas.
When any comet approaches a sun it can deliver a tail of dust or gas.
hope this will help you
Answer: d). UAG
Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.
From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
