What are the categories of population? There are three types of population pyramids: Expansive Pyramid. It is triangular in shape wherein each age group displays a bar shorter than the one preceding it, symbolising that more people die as we progress through the pyramid. Constrictive Pyramid. Stable Pyramid. How can we classify population? Population centres […]

Are bacteria and fungi decomposers? Most decomposers are microscopic organisms, including protozoa and bacteria. Fungi are important decomposers, especially in forests. Some kinds of fungi, such as mushrooms, look like plants. But fungi do not contain chlorophyll, the pigment that green plants use to make their own food with the energy of sunlight. Are fungi […]

What is a group of organs working together called? organ system What is a group of organs that work together to perform a certain function in an organism’s body? An organ system is a group of organs that work together to carry out a complex overall function. For example, the skeletal system provides structure to […]

What statement is true about diffusion? Diffusion requires energy input from the cell. Diffusion is only important for animal cells. Only water can diffuse across a cell membrane. Molecules move from areas of high concentration to areas of low concentration. Why is diffusion important to animals? Diffusion is important to cells because it allows them […]

What organ systems do frogs have? A frog’s heart, lungs, and digestive systems are all found in one single hollow space. Our internal organs are housed in three distinct cavities: chest, abdomen, and pelvis. Frogs breathe through their skin. Which organs or organ systems work together to accomplish reproduction in frogs? In a male frog, […]

How vesicles are formed? In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion (exocytosis), uptake (endocytosis) and transport of materials within the plasma membrane. What is vesicular transport in biology? Vesicular transport is […]

How do fertilizers cause algal blooms? Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow. When the algae and seagrass […]

How do you find the frequency of a wave in Hertz? Frequency of a wave is given by the equations: f=1T. where: f is the frequency of the wave in hertz. T is the period of the wave in seconds. f=vλ where: f is the frequency of the wave in hertz. v is the velocity […]
