Answer: monocular cue
Explanation:
The key reason one don't lose sense of depth is because of monocular cue. Our brain can still detect the actual position of the object with helps of cues even if one eye is closed.
Such cues include (but are not limited to):
- Linear perspective - the fact that additional objects ultimately travel to a single point (i.e. two roads that converge into a single point in the distance)
- Texture - objects closer to you will have more complex texture compared to objects further away from
- Interposition - objects closer to you will be farther away from objects
- Accommodation - as you look closely at items, your eyes need to accommodate and concentrate on them using your eye muscles, giving your eyes an idea of where the object is located.
Hence, Monocular Cues are used by using one eye to help sense distance.

Explanation:
Answer:
Explanation:
A. Cancer cells are cancerous because they divide all the time. Normal cells stop dividing once there's enough of them but cancer cells divide when not required as well. Therefore, if Ras is mutated it will always be "on" which means it will activate the pathway which will lead to division of cells i.e. cells divide to multiply their numbers so more cells will be made. Normally, cells only multiply whne there's the growth factor present to activate the whole pathway, but since Ras is mutated it doesnt need the growth factor to activate the pathway, it automatically always activates the pathway even in absence of growth factor.
B. It is highly unlikely that the proposed drug will have a useful effect. This is because mutant Ras protein of this type behaves as though it is constantly "on". Ras acts downstream of the receptor, i.e. first you have the reception of growth factor in receptor, then the ras gets activated. However, the activating mutation makes its effect felt (Ras is activated no matter if there's a growth factor or not), which is why mutant Ras is always active and no longer dependent on the receptor for activation.
Therefore, blocking the ability of the receptor to dimerize and activate Ras will probably not have an effect on cells containing the mutant Ras protein as it does not inhibit the activity of mutated Ras protein.
