Answer:
In the extracellular space
Explanation:
Disulfide bonds are interconnections between chains (or between parts of a chain) formed by the oxidation of cysteine radicals, this reaction is catalyzed by specific enzymes.
Intracellular proteins have no disulfide bonds, which are more common in proteins secreted into the extracellular environment.
Disulfide bonds do not form in the cytoplasm because there are a lot of reducers in the cytoplasm (intracellular environment) , making the disulfide bonds unstable. The reducing environment of cytoplasm causes disulfide bonds (S-S) to return to the form of cysteine groups (-SH).
Explanation:
A sugar is a source of carbohydrate which is made up of carbon and oxygen atoms. Providing a yeast with more amount of sugar will increase the process of fermentation which is the anaerobic respiration. The carbon dioxide will be released after this process. The released carbon dioxide gas can be measured by observing the shape of the balloon and measuring the quantity of carbon dioxide present in the balloon.
Answer:
C. Standing upright allowed for sightlines over tall grasses and savanna shrubbery
Explanation:
One of the most accepted theories about the development of bipedalism of the hominids is that it was mostly because of the tall grasses and shrubs, so standing upright was providing them with better view. Once the environment changed, and the tropical rainforest was turned into savanna, the hominid ancestors had to adapt in order to survive. Being helpless against the large predators, they needed something in order to be able to detect them from bigger distance so that they can avoid them. The solution seemed to be to be able to see above the tall grasses and shrubs, which meant that they started to use their legs more and more in order to stand up taller. This gradually led to better development of legs for upright standing and walking, also causing changes in the structure of the body, providing the hominids with an adaptation that enabled them to survive in the very dangerous environment.
