Answer (1)
All mixtures are beneficial to humans. - F
Not all mixtures are beneficial to humans. Some mixtures can be harmful, such as polluted air or contaminated water, which can have negative effects on health and the environment.
Expiration dates placed in food and medicine must not be taken seriously. - F
Expiration dates are important indicators of the safety and effectiveness of food and medicine. Consuming expired products can lead to health risks or reduced effectiveness in the case of medicine.
Trails of plastic bags found in oceans is an example of a harmful form of mixture. - T
Plastic bags in the ocean are indeed harmful as they constitute pollution, which affects marine life and ecosystems. They break down into microplastics, which can be ingested by marine organisms and enter the food chain.
Researching about the substances that will be used in forming mixtures is not important. - F
Researching substances is crucial, as it helps to understand the properties, safety, and potential reactions between components. This ensures that mixtures are beneficial and safe for intended use.
An alloy is a type of solution made from combining two or more substances or metals. - T
Alloys are indeed a type of mixture known as a homogeneous mixture. They are solutions consisting of two or more metals or a metal and another element, like steel (iron and carbon) or bronze (copper and tin), which have uniform properties throughout.
