Answer:
The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist...hope it helps..
Answer:
can be mutualistic or antagonistic.
Explanation:
According to the given information, the bacterial species <em>Staphylococcus aureus </em>present in some nasal passages and on the skin do not harm the person. The ecological interaction wherein both organisms are benefited and none is harmed is known as mutualism. Here, <em>Staphylococcus aureus</em> does not cause any disease in human when present on the skin and in the nasal passage, that is both are in mutualism.
However, when present in the bloodstream, the same bacterial species can cause infections such as sepsis and represents antagonist effects on the host.
Hence, the <em>staphylococcus aureus </em>species may be mutualistic or antagonistic to human.
Answer:
Protein synthesis in rough endoplasmic reticulum (RER) and packaging in smooth endoplasmic reticulum (SER)
Explanation:
Intracellular Protein Transport:
- After transcription in the nucleus, the mRNA is translocated from the nucleus to the ribosomes attached to the rough endoplasmic reticulum (RER). The RER is the site of the biosynthesis of proteins.
- The process of translation of mRNA sequence into amino acid sequence takes place in the RER.
- The newly synthesized protein is then packaged into vesicles in the SER and transported to the Golgi complex.
- The Golgi complex is the cell's packaging department. It packages proteins into transport vesicles for intra and extracellular protein transport.
C - Eukaryotes and heterotrophic.
Good luck!
Enzymes are proteins that are biological catalysts
They reduce the activation energy required for a reaction to occur and thus speed up a reaction
Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)
They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's
They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.
They aren't used in the reaction so they're re-usable.
If it isn't one of these then it is not one of the properties of enzymes
