Answer:
B) A -1 base pair deletion shortly after the start codon.
Explanation:
A base pair deletion right after the start codon will block the protein function because it will cause the entire reading frame to shift. Therefore the protein which will be synthesized out of such mRNA will be non-functional because it will be entirely different from that of the original protein.
In other options, the protein synthesized will not be this much different from the original protein and hence it will be functional although the efficiency of the protein will be less as compared to original protein.
The protein which will be synthesized as described in option A will be same as of original protein because a base pair insertion after stop codon does not impact the protein composition at all.
The protein which will be synthesized as per option c will have only one amino acid difference as compared to the original protein so it will be functional. Similarly the protein synthesized as per option D will also be functional because the only amino acid which will be different from the original protein will be the last amino acid of the polypeptide and hence will not affect the function of protein adversely.
Answer:B
Explanation:when fat are ingested,it has to be emulsified and broken down into monoglycerides,fatty acids.these molecules have a polar hydrophilic end and a non polar hydrophobic end .the fatty acid and monoglycerides that enter the cells of the mucosa are formed back into large tryglycerides molecules ,which then forms chylomicros, which are water soluble.they then pass into the lacteal vessels from where there are Transported to meet the body's needs
Answer:
Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily. Basically, it reduces the activation energy and makes the reaction occur faster.
Answer:
Lets be clear, in an inertial frame of reference it will take 1 newton to move 1 kilogram 1 meter in one second(roughly). 1 joule in that newton, 1/speed of light = incremental mass increase( irrelevant) . So, to move 1 kg of mass 1 meter in 0.00000003 seconds would take 300,000,000 joules(fun).
That divided by speed of light again and your 1kg mass is now 2 kg. Now to move 2 kg 1 meter would take more energy than previously. More energy (newtons) the more relativistic mass gained and thus more energy required to move faster. This is why we cant reach the speed of light - infinite energy. ( again irrelevent to the Question).
But in your question you said lift. Lift is a term that I would find on earth, in a gravity well, so moving that same 1kg of mass wouldn't take 1 newton because the gravitational force pulls the mass down, causing a force called weight - this would be 9.8 N x Mass at sea level. So to lift this 1kg mass will take more than 9.8 N. 10 newtons of life would create a net force of 0.2 N so 0.2/1 = 0.2 meters acceleration.
Note that, gravitational force is one side of the same coin, with acceleration on the other. We talk of gravitation in terms of acceleration, as two masses that are not identical will always fall at the same acceleration. Gravity isn't a force, its a four dimensional field that curves linear paths toward attracting bodies - this is how we are able to orbit objects in space.
Sensation is a process that takes in stimuli from our bodies and environment, while perception organizes the stimuli into meaningful objects and events
