Answer:
d_neither is eukaryotic because it has has
4000 years 50% is left that's half and you figure it keeps the same rate of reduction
Carbon sinks refers to carbon reservoirs that are increasing in size. In the diagram given above, the carbon sinks are the ocean and the land.
The main natural carbon sinks in nature are the ocean, soil, plants and other organisms, which uses photosynthesis to remove carbon dioxide from the atmosphere.<span />
Hypothesis: If the pH is related to the growth of oysters and oysters are placed in water with varying pH levels to test growth, then (INSERT YOUR LEVELS HERE, MORE BASIC WILL HAVE THE BEST GROWTH, MORE ACIDIC WILL HAVE THE WORST GROWTH. WHAT IT SHOULD LOOK LIKE then the pH of 3 will have the least amount of growth followed by the pH of 5, 7, and 9.). This will happen because a lower pH means less carbonate which oysters require to build their shells. As the acidity rises, oyster's shells will become thinner meaning slower growth and death rates will rise.
Independent Varible: pH (I would probaly also add the pH of what like it should be the pH of water)
Dependent Variable: oyster growth
The correct answer is: They usually have one or more helical regions spanning the membrane bilayer
Transmembrane proteins are type of integral proteins meaning that they are permanently attached to biological membrane. Transmembrane proteins span through the plasma membrane so most of their structure is hydrophobic.
The major role of these proteins is transport role: they act as a channels that undergo conformational change in order to move a substance through the membrane.
Classified by their structure they can be put into two types: alpha helical and beta barrels.
