Answer:
Changes in the composition of the atmosphere
Explanation:
Although this answer is very vague and generalized, it is the correct answer.
The increase in greenhouse gas emissions in the atmosphere from modern manufacturing and engineering has increase carbon dioxide and methane concentrations in the upper atmosphere. These gasses have a chemical composition that allows the absorption and release of longwave radiation back to the Earth's surface slowly increasing the global average temperature.
Answer:
A. The gene for surface protein was transcribed and translated.
Explanation:
Because all living organisms use the same genetic code, it is possible to express genes from one organism in the other. In this case, the DNA sequence that corresponds to the hepatitis B surface protein gene has been inserted into the banana, and the protein is expressed.
For the protein to be expressed, the gene must have been successfully transcribed into an mRNA by the banana plant machinery. This mRNA has then been translated into a protein that means the hepatitis B surface protein is now present in the cell.
When a volcano erupts , a mixture of gases and particles is released into the air . The cooling influence of an individual volcano will dominate for the period immediately after the eruption but the warming impact will last much longer.
Coenzymes
Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions.
Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.
Biodiversity supports biological system efficiency where every specie, regardless of how little, all have a vital part to play. For instance, A bigger number of plant species implies a more prominent assortment of products. More noteworthy species assorted variety guarantees common maintainability for all living things.
