Answer: The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species. Changes in Earth's system affects the growth of life on Earth. ... Life on Earth includes all the living things such as plants animals humans microbes etc. All take part in different cycles such as carbon cycle and nitrogen cycle and can influence global climate by changing chemical composition of atmosphere.

Answer:
The answer is A
Explanation:
There are certain types of proteins that need to be sinthesized in the rough ERC in order to reach its final destination. These proteins are:
- Proteins that need to be exported from the cell.
- Proteins that need to be docked to either endomembranes or the plasma membrane.
- Hydrolytic lysosomal enzimes.
- Proteins that have a function in the lumen of certain organelles such as the endoplasmic reticulum, golgi or the nuclear envelope.
Hemoglobin doesn't fit in any of these cateogories, given that it is a cytoplasmic protein. Therefore, its synthesis begins and ends in the cytoplasm, where the protein performs its function.
<span>The synthesis of proteins takes two
steps: transcription and translation. Transcription takes the
information encoded in DNA and encodes it into mRNA, which heads out of
the cell's nucleus and into the cytoplasm. During translation, the mRNA
works with a ribosome and tRNA to synthesize proteins.</span>
