Answer:
E. They decrease the rate at which Ras hydrolyzes GTP.
Explanation:
Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.
Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.
Hypertonic, the extra water causes the cells to swell.
Answer:
4) Some people consider human genetic experiments
unethical.
Explanation:
1) Humans have DNA that is structurally very different from
other mammals.
2) Cloning can only he performed on animals that normally
reproduce asexually.
3) Human genes are made of too many different types of
simple sugars.
4) Some people consider human genetic experiments
unethical.
The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.
<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>
<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>
<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>
The correct option is 4.
Adenosince Triphosphate is broken down into one molecule of inorganic phosphate and a molecule of adenosine diphosphate, the energy released from this bond is captured and use to drive most cellular processes. some form of carbohydrate or triglyceride is used to generate the ATP in the first place depending upon a particular species and needs at the time
