D. it serves as a link between membrane proteins on adjacent membranes.
It has pairs of matching chromosomes
I hope this helps!
Trait is an obvious, observable, and measurable trait; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color
Explanation:
D) 75 J
Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.
With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.
