OLIVIA GRACE STUDY NOTES

Let’s get real: the HESI A2 exam is a big deal if you’re aiming for a career in nursing or healthcare. And the biology section? Yeah, it’s a real beast. But don’t sweat it too much. I’m here to help you understand what to expect and, more importantly, how to kick ass when it’s test time.

What Kind of Questions Are on the HESI A2 Biology Section?

The HESI A2 biology section is designed to test your knowledge of core biological concepts. It’s not just about memorization; you need to actually understand this stuff. Here’s a breakdown of the key areas covered and the types of questions you might encounter:

Cell Biology

This is the heart of the section. Expect questions about cell structure and function, including the roles of various organelles like mitochondria, ribosomes, and the nucleus. You might also get asked about cellular processes like mitosis and meiosis.

Genetics

Genetics is another big topic. You might get questions about DNA structure, RNA, transcription, translation, and the basic principles of heredity. Think Punnett squares and dominant/recessive traits.

Evolution and Ecology

Yes, evolution is part of biology, so be prepared for questions on natural selection and adaptation. Ecology questions are also common, focusing on ecosystems, food chains, and how organisms interact with their environment.

Human Biology

Let’s not forget about the human body. This section often includes questions about human anatomy and physiology, covering major systems like the circulatory, respiratory, and digestive systems. You might get a question about how blood circulates or what happens during digestion.
