select the statement(s) that accurately describe ways that bacteria can affect the human body.
bacteria can cause tooth decay.
bacteria can give you shiny hair and clear skin since they are infectious agents and kill other bacteria on your skin or hair.
bacteria can cause skin issues such as pimples.

a serious bacterial infection can lead to death.

Explanation:

• Bacteria like Streptococcus mutans contribute to tooth decay by breaking down sugars and producing acid that erodes tooth enamel.
• Certain bacteria (e.g., Propionibacterium acnes) are linked to skin issues such as pimples by clogging pores and causing inflammation.
• Pathogenic bacteria in the digestive tract (e.g., Salmonella) can lead to digestive issues like diarrhea and cramping.
• Severe, untreated bacterial infections (e.g., sepsis from widespread bacterial growth) can be life-threatening and lead to death.
• Bacteria do not produce shiny hair or clear skin by killing other bacteria; this claim is inaccurate.
