Answer:
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the Occipital lobe is primarily responsible for vision.
Explanation:
Occipital lobe is primarily responsible for vision.
Answer:
C.Never swims fast
Explanation:
RacerX and Speed protein need to bind to each other for the cilia to beat faster which would make the protozoan swim faster. However, Speed needs to be phosphorylated to be able to bind to RacerX. Thus, phosphorylation of Speed is necessary for the fast movement of cilia.
Threonine residue is phosphorylated in Speed protein. It occurs on its side chain through the formation of phosphoester bond. Apart from threonine, phosphorylation can take place on serine and tyrosine side chains again through the formation of phosphoester bond. It can also occur on histidine, lysine and arginine by formation of phosphoramidate bonds.
Since, alanine can not form any of these bonds it can not be phosphorylated. Hence when threonine is substituted with alanine in Speed protein, it can not be phosphorylated. Racer X wont be able to bind to Speed and cilia wont beat faster. As a result the protozoan will never swim fast.
