Redness and swelling may develop in an area near a wound. This reaction

which of the following?*
circulatory system
nervous system
muscular system
skeletal system

Circulatory system carries white blood cells to infected area.

Explanation:

White blood cells are also referred to as the immune cells as they help in the immune process. White blood cells also fight infections.

White blood cells make their way to the infected part of body through the blood vessel walls.

There are various types of white blood cells, namely lymphocytes, monocytes, eosinopohils, basophils and neutrophils.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
