Of the three types of muscle contractions we have discussed (eccentric/lengthening, concentric/shortening, and isometric/steady), which one do you think you experience most often during a normal day? How about if you are doing a physical activity? Please give examples for both a normal day muscle contraction and a physical activity muscle contraction.

answer

ben’s food poisoning was caused by cross-contamination

explanation

cross-contamination in food occurs when harmful bacteria is transferred to food from other foods, utensils or cutting boards. it happens often when handling raw meat , sea foods and poultry. in this case, because ben did not wash hands before and after handing the poultry, chances that bacteria transfer   from the poultry to the vegetable are high.
