We ain’t GOD created us separate
Answer:
According to the diagram and the interaction of the structures to express information in the cell, it is true that:
- Molecule B can be used to produce molecule A.
- Molecule A can be used to produce molecule C.
Explanation:
Molecule A is a double stranded DNA, molecule B is a strand of RNA and molecule C is an amino acid encoded by a codon.
The DNA is capable of splitting and from one strand producing the messenger RNA, in the process of transcription.
Messenger RNA contains a sequence of bases, and the set of 3 bases of RNA form a triplet or codon. A specific amino acid can be formed from a codon. This process is called translation.
The way in which molecules A, B and C interact is through the processes of transcription and translation, making it possible to use genetic information for protein synthesis.
The other options are not possible because:
- <em>Only DNA can replicate, RNA needs the transcription to be synthesized.
</em>
- <em>Molecule B and C do not interact so that the amino acids are together, but this depends on the sequence of bases in the RNA.</em>
The answer is D. The life cycle of a star is dependent on its mass. Stars by forming at nebulas as protostars. When the sun exhausts hydrogen fuel at its core, the core begins to fuse helium to carbon and the core becomes hotter but smaller. The outer layers are pushed outwards and the sun becomes larger and paler. Later, the helium fuel begins to run out and the sun loses the outer expanding layers into a planetary nebula. The remaining core is a white dwarf.
Stars that are 10 times our sun's solar mass just explode to supernovas when their hydrogen fuel is exhausted.
The correct answer would be D, post industrial.
