Autotrophs are called producers, because they produce their own food. Herbivores, carnivores, and omnivores are consumers. Herbivores are primary consumers. What is an example of a carnivore herbivore and omnivore? […]

In which phase of the cell cycle is the most time spent? interphase Do cells spend most of their time in prophase? this is because, cell spends approximately the same amount of time in each mitotic phase (prophase, metaphase, anaphase, telophase). it doesn’t spend more time in prophase than any other phase. Why prophase is […]

What is the spread of bacteria from one food to another food called? cross-contamination Which of the following contaminants is a physical contaminant? Physical contamination occurs when physical objects contaminate food. Common physical contaminants include hair, glass, metal, pests, jewellery, dirt and fake nails. What is contamination cross contamination? Contamination is the introduction of a […]

Which term identifies the process used by the cell to bring in large molecules? Endocytosis How are large molecules removed from the cell? In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles. Instead, cells use one of two primary mechanisms that […]

How does cactus photosynthesis? Cacti are plants that have succulent stems, pads or branches with scales and spines instead of leaves. All plants photosynthesize, collecting carbon dioxide through holes in their leaves called “stomata” and converting it into sugar and oxygen. Cacti utilize CAM photosynthesis, a process unique to succulents. Where does photosynthesis take place […]

What is the process for plants to break down nitrogen? To be used by plants, the N2 must be transformed through a process called nitrogen fixation. Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems. How do nitrogen-fixing bacteria break the triple bond in nitrogen molecules? Just a […]
