No, peroxisomes are separate organelles that do not belong to the ER-to-Golgi membrane traffic network inside eukaryotic cells. That answer is short, but the reason behind it is where most students get tripped up. Peroxisomes do have a membrane. They do work with lipids. They can even trace some of their membrane origin back to […]

Some sexually transmitted viruses can be treated, but treatment often controls the infection instead of removing it from the body. Hearing that an STI is viral can feel heavy. The word itself often sounds final. It isn’t that simple. Some viral STIs can be controlled with medicine, some symptoms can be treated directly, and some

Yes, heavy drinking can raise blood pressure, and even regular moderate intake may push readings up in some adults. Alcohol and blood pressure have a messy relationship.

Yes, a head cold can trigger dizziness when congestion, ear pressure, dehydration, fever, or cold medicine throws off normal balance. A stuffy nose and sore throat are easy to spot. Dizziness is the symptom that throws people off. One minute you have a plain cold, and the next you feel lightheaded when you stand up,

No, a properly spayed cat cannot become pregnant, but rare surgical leftovers or confusion about the procedure can make it seem possible.
