About This Chapter
How it works:
- Begin your assignment or other high school biology work.
- Identify the biological system requirements concepts that you're stuck on.
- Find fun videos on the topics you need to understand.
- Press play, watch and learn!
- Complete the quizzes to test your understanding.
- As needed, submit a question to one of our instructors for personalized support.
Who's it for?
This chapter of our high school biology tutoring solution will benefit any student who is trying to learn about requirements of biological systems and earn better grades. This resource can help students including those who:
- Struggle with understanding living systems requirements, environmental requirements for growth and reproduction, feedback systems or any other biological systems requirements topic.
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their requirements of biological systems unit
- Cope with ADD or ADHD
- Want to get ahead in high school biology
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about biological systems requirements simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about requirements of biological systems on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Understand why free energy and matter are required for the growth, reproduction and maintenance of living systems.
- Explain the environmental requirements for growth, reproduction and dynamic homeostasis.
- Learn how feedback systems allow organisms to regulate growth, reproduction and dynamic homeostasis.
1. Living Systems Requirement for Free Energy and Matter
Free energy and matter are required by all living things in order to grow, reproduce, and maintain biological processes. Additionally, free energy and matter must also be recycled through the environment in order to remove dead material and allow for new growth.
2. The Environmental Requirements for Growth, Reproduction & Dynamic Homeostasis
Cells need to maintain internal environments that are different from their external environments in order to grow and reproduce. In this video lesson, you will understand some ways that cells can control their internal conditions to ensure proper biological functioning.
3. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis
In order to maintain specific internal conditions, organisms use feedback mechanisms. Feedback is essential to the regulation of internal environments, which allows for proper biological functioning.
