Question

Why might the brain be particularly susceptible to accumulating plastics, according to the study?
The brain is about 60% fat by weight, which attracts plastics.
The brain has a high water content, which attracts plastics.
The brain’s electrical activity attracts plastics.
The brain’s high protein content attracts plastics.

What is the size distinction between microplastics and nanoplastics?
Microplastics are fragments less than 1 millimeter, while nanoplastics are smaller than 5 millimeters.
Microplastics are fragments less than 1 millimeter, while nanoplastics are smaller than 1 millimeter.
Microplastics are fragments less than 5 millimeters, while nanoplastics are smaller than 1 nanometer.
Microplastics are fragments less than 0.5 millimeters, while nanoplastics are smaller than 0.1 millimeter.

1. Why might the brain be particularly susceptible to accumulating plastics? – Correct Answer: The brain is about 60% fat by weight, which attracts plastics. Explanation: Plastics are lipophilic, meaning they are attracted to fat. Since the brain has a high fat content, it can more easily accumulate plastic particles. 2. What is the size distinction between microplastics and nanoplastics? – Correct Answer: Microplastics are fragments less than 1 millimeter, while nanoplastics are smaller than 1 millimeter. Explanation: Microplastics are defined as plastic particles that range in size from larger pieces down to 1 millimeter, whereas nanoplastics are even smaller, specifically falling below 1 millimeter in size.
