Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.

Because for the strands to form a double helix the base pairs have to match perfectly (adenine with thymine and cytosine with guanine) in DNA , and if a strand of RNA is paired with a split strand of DNA it goes adenine with uracil and cytosine with guanine (uracil replaces thymine)
Flexibility exercises have been prescribed successfully to treat dysmenorrhea (painful menstruation), general neuromuscular tension (stress) and knots (trigger points) in muscles and fascia. What are the benefits of good flexibility? -enhances quality of life -promotes healthy muscles and joints -greater freedom of movement -makes activities of daily living easier -promotes healthy muscles and joints -Improves elasticity of muscles and connective tissue around --joints, enhancing freedom of movement -Makes activities of daily living (turning, lifting, and bending) much easier to perform -Helps prevent low back and other spinal column problems -Improves and maintains good postural alignment -Promotes proper and graceful body movement -Improves personal appearance and self-image -Helps develop and maintain motor skills throughout life
