How energy is transferred from the Sun to a plant? Plants also convert sunlight into other forms of energy. In this case plants convert light energy (1) into chemical energy, (in molecular bonds), through a process known as photosynthesis. The plants convert a tiny amount of the light they receive into food energy. Which part […]

Why is nutrition important for a living organism Class 7? The nutrients enable living organisms to build their bodies, to grow, to repair damaged parts of their bodies and to provide the energy to carry out life processes. Why is nutrition necessary for organisms give two reasons? Nutrition is required for an organism for the […]

What are the waste by products of solar energy? The International Renewable Energy Agency (IRENA) estimated that at the end of 2016, there were around 250,000 metric tonnes of solar panel waste globally [12]. The solar panels contain lead (Pb), cadmium (Cd) and many other harmful chemicals that could not be removed if the entire […]

What is the percentage of guanine in a DNA sample containing 20% thymine? 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal […]

What type of weather does a cold front bring? Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed. Can a cold front lead […]

What do we call the smaller molecules from which the macromolecules are built? monomers What are large molecules made from smaller organic molecules? Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an […]

Can a human travel a light year? This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year. How fast is a […]

What is the main function of a vacuole in a cell quizlet? Vacuoles are membrane-bound organelles used to store substances within the cell. the tonoplast or central vacuole of plant cells retained water to give the plant cell rigidity and support. Vacuoles also serve as storage sites for materials used by the cell, such as […]

When cells break down food molecules energy is released all at once? cellular respiration. When living cells break down molecules, energy is , stored as ATP, released as heat, BOTH B AND C. What happens to the energy when cells break down food molecules? When living cells break down molecules, what happens to energy? It […]

How do membrane proteins perform communication? Membrane signaling involves proteins shaped into receptors embedded in the cell’s membrane that biophysically connect the triggers in the external environment to the ongoing dynamic chemistry inside a cell. What is the importance of protein in cell membrane? For example, plasma membrane proteins carry out functions as diverse as […]
