Answer:

The correct answer is d all of the above

Explanation:

There are many reasons behind increasing the concentration of atmospheric carbon dioxide such as

1 Burning of fossil fuels such as coal,petroleum increases the level of atmospheric carbon dioxide.

2 Increase in Argiculture also increases the level of green house gases such as CO2.

3 Clearing of lands for increasing population and agriculture by cutting down trees also adversely effect the normal 02:CO2 ratio in the atmosphere.

Why are scientists interested in the origin of organic molecules? help me please...

valentina_108 [34]

Answer:

Gas from Earth's core came to the surface through volcanoes.

Recent hypotheses about the origin of organic molecules suggest that these molecules may have formed in hydrothermal vents deep in the oceans, where hot gases and elements emerge from cracks in Earth's crust.

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome.Match the wo

vredina [299]

1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.

tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with the amino acids they encode.tRNA has anticodone that binds to mRNA codone.

2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.

Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).

3. Initiation of translation always happens at the start codon of the mRNA.

Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).

4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.

These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.

5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.

Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.
