Energy Stores: Revision Quiz
Learning and revising the topic of energy stores can be daunting, but it can become more manageable with the right tools and knowledge. These questions are designed to help students understand and learn the fundamental concepts of energy stores.
Energy Stores
We use energy to fuel movement and light, which can be found in various forms, such as light waves, heat waves, sound waves and kinetic energy. When we use energy, it is not destroyed but transferred from one entity or energy source to another.
Non-Communicable Diseases
Non-communicable diseases are diseases that cannot be caught from another person or animal. Cancer is a good example of non-communicable disease.
Cardiovascular Disease
The heart and blood vessels can be affected by many things. Many of these issues can be effectively treated if you know how.
Health and Disease
Poor health can be caused by diseases. Often, different diseases interact, and this can lead to further health complications that don't seem related at first.
Transpiration and Translocation
Animals and plants both have transport systems for moving substances around. Water is transported from the roots to the leaves during transpiration in xylem vessels for photosynthesis. All cells inside phloem vessels use glucose made during photosynthesis for respiration.
Plant Cell Organisation
The cells of plants are arranged in a similar fashion to those of other multicellular organisms. The cells of an organism form tissues, the tissues form organs, and the organs form organ systems.
The Circulatory System: Blood and Blood Vessels
Throughout our bodies, blood travels through blood vessels. There are three different types of blood vessels you should know about: Arteries, Capillaries and Veins.
