Explanation:
NEAR remained in this orbit for 10 days and then was backed out in stages to a 100 km circular orbit by September 5, 2000. Maneuvers in mid-October led to a flyby of Eros within 5.3 km of the surface at 07:00 UT on October 26.

Vasectomy and Tubal ligation are operations that have an effect on meiosis in individuals who have elected to have these operations in that it causes meiosis to stop.
A vasectomy or Tubal ligation are operations that are often performed as a method of birth control. A vasectomy is the male version of the operation and includes a procedure that negates the gametes or sex cells from reaching the sperm and being ejected from the body, thus preventing fertilization.
Tubal ligation is a similar process performed on women. The goal of this operation is the same as in the vasectomy, to stop the "egg cell" from being released and thus preventing it from being fertilized. Both procedures have been shown to cause meiotic arrest in individuals following the operation, In some cases, meiosis resumes after some time.

Answer and explanation;
Contraction of skeletal muscles;
-An action potential from a motor neuron triggers the release of Ca2+ ions from the sarcoplasmic reticulum.
-Calcium ions expose the myosin heads by binding to a blocking molecule (troponin complexed with tropomyosin) and causing it to move.
-The myosin heads form a cross-bridge with actin binding sites.
-ATP binds to the myosin heads and breaks the cross-bridge.
-The hydrolysis of ATP causes the myosin heads to change shape and swivel - this moves them towards the next actin binding site.
-The movement of the myosin heads cause the actin filaments to slide over the myosin filaments, shortening the length of the sarcomere.
-Via the repeated hydrolysis of ATP, the skeletal muscle will contract.
