Reema wished to be a participant in the Annual Sports Day. After she took part in athletics for the sports selection, she suffered severe muscular pain. a) Why did Reema get a muscular cramp after running?
b) Which type of respiration took place in her muscle cells while
running? Suggest a way for Reema to overcome her pain.

Hey there mate ;)

According to questions:-

(i) Reema got muscular cramps because excessive anaerobic respiration has taken place. Since she took part in athletics, her legs had to run as fast as possible. which means that her heart beat rate became faster. Therefore, lactic acid along with other substances was formed in her legs.

(ii) During Reema's running, anaerobic respiration took place. In order to relieve her pain, she can do three main steps :-

★ Reema can take a hot shower, which can help her with her tight legs.

★ She also can apply warm towel to increase the flow of blood in her legs again.

★ Or else, Reema can be given a massage, which is the easiest and most accurate option.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
