Which part of a prosthetic limb keeps the prosthetic attached to the residual limb?
snow_lady [41]

Answer:

C. Suspension system

Explanation:

When dealing with prosthetic limbs the suspension system is how the prosthetic remains attached to the residual limb. This system makes sure that the prosthetic is firmly attached and only has the necessary movement for the prosthetic but nothing more. There are a couple of different suspension systems, the three most widely used ones would be Anatomic suspension, belt suspensions, and upper limb suspension systems.

A heterozygous, three-horned alien from Mercury has met and fallen in love with a four-horned alien from Jupiter. What would hap
Gnesinka [82]
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen.  If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
