3 ohms i pass the test with this being the correct one
Answer:
6.5 cm
Explanation:
Mechanical advantage is a measure of efficiency or performance of a tool or machine in terms of force amplification which is done by the machine or tool. In simple terms, it measures that at what extent the applied force is increased with the help of tool or machine.
Mathematically, it is the ratio of force produced by the tool or machine to the force actually applied to the tool.
In terms of effort length and resistance length, it is calculated as -
Mechanical advantage = 
Thus, Mechanical advantage = 
= 6.5 cm.
Answer:
polar microtubules contract, pulling attached chromosomes toward the poles.
Explanation:
Polar microtubules are one of the two types of microtubules that together make the mitotic spindle. The polar microtubules are the ones that extend from each pole to the cell's equator.
At the equatorial region, the polar microtubules from two poles overlap. Also known as non-kinetochore microtubules, the polar microtubules do not get attached to the kinetochores of chromosomes.
The function of the polar microtubules is to assist in chromosome separation during anaphase. The polar microtubules from two poles slide past each other. As they slide, the degree of overlap is reduced and the two opposite poles are pushed apart.
The reduced overlap between the polar microtubules indirectly moves the chromosomes apart as the kinetochore microtubules attach the chromosomes to the opposite poles.
Answer:
Sequence of amino acids by the ribosome are the characteristic of a protein may change during a DNA mutation.
