Combustion of fossil fuels
Explanation:
The most likely source of the carbon dioxide shown in the graph is the combustion of fossil fuels for both industrial and domestic use.
- Fossil fuels are hydrocarbon units.
- They burn in the presence of oxygen gas to from carbon dioxide and water.
- The level of carbon dioxide has been increasing dramatically with increase in industrialization.
- The fuels are used and needed for the workings of machinery.
- Domestically they are used in heating homes and powering automobiles.
- These processes produce carbon dioxide as a waste product.

Answer:
Translation
Explanation:
Protein synthesis is the process of production of proteins in in the cells of living organisms. Transcription and Translation are the two main steps in the protein synthesis. The first step is completed in nucleus where mRNA is made using DNA as template. The second step i.e. translation occurs in the cytoplasm with the help of Ribosomes. The mRNA synthesized during transcription is pre-mRNA. After the processing it is assembled as mature RNA. After getting assembled the second step of protein synthesis viz. Translation begins in the cytoplasm.
Answer: HA + H2O ⇌ H3O+ + H- (option #4)
Explanation: Since the acid is weak you have to use a ⇌ (equilibrium) sign. Equilibrium is denoted in a chemical equation by the ⇌ symbol. Also, when any acid dissolves into water, it produces hydronium (H3O+ or H+). Therefore, the fourth chemical reaction is your answer.
