Producers get the energy they need from the sun. Consumers get their energy from the plants and animals that they eat. Decomposers get energy from eating dead plants and animals.<span />
Griffith's experiment worked with two types of pneumococcal bacteria (a rough type and a smooth type) and identified that a "transforming principle" could transform them from one type to another.
At first, bacteriologists suspected the transforming factor was a protein. The "transforming principle" could be precipitated with alcohol, which showed that it was not a carbohydrate. But Avery and McCarty observed that proteases (enzymes that degrade proteins) did not destroy the transforming principle. Neither did lipases (enzymes that digest lipids). Later they found that the transforming substance was made of nucleic acids but ribonuclease (which digests RNA) did not inactivate the substance. By this method, they were able to obtain small amounts of highly purified transforming principle, which they could then analyze through other tests to determine its identity, which corresponded to DNA.
Answer:
Jean-Baptiste Lamarck
Explanation:
Jean-Baptiste Lamarck was a French biologist which developed the first theory to understand how species change (evolve) over time. This evolutionary concept was published under the name of 'Theory of the Transmutation of Species' in the early 19th century. Subsequently, Darwin published his famous and widely accepted evolutionary theory in the book 'On the Origin of Species' (1859).
E=hv is an equation important when dealing with light. E refers to the energy of a photon; h is Planck's constant and v is the wavelength. According to this equation, light particles called photons travels in packets of energy. This is important in pv cells because this is the technology used to harness solar energy which is converted to electricity. The amount of energy should be estimated to know the appropriate material of construction of the pv cell to achieve optimum conditions. In this way, the pv cell could maximize the sun's energy.
Cells are the basic units of structure and function in living things, all cells are produced from other cells, all living things are composed of cells.
