Answer:
presence of cells
Explanation:
All living things are composed of cells. A cell can be defined as a complex biological arrangement that has all the structures and materials required for life. Cells carry out specialized functions such as, for example, metabolic functions to convert nutrients from food into energy (ATP), and reproduce by mitosis and/or meiosis. Thus, the cell is known to be the basic unit of life.
Answer:
During meiosis I, the cell is diploid because the homologous chromosomes are still located within the same cell membrane. Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid.
Nutrients, for example, (sugars and starch) and proteins can be recognized by the use of an indicator, which is a synthetic that delivers a trademark shading when a specific substance is available.
Answer:
In an ecosystem, all organisms benefit in the process of transformation of energy.
Explanation:
An ecosystem works thanks to the constant transformation of energy. In the case of microorganisms that act as producers, they benefit the rest of the ecosystem in terms of energy transfer because they acquire the energy from a lowest trophic level to make it available for higher trophic levels.
In the case of the primary consumers, they are feeding from the primary producers, incorporating that energy to be part of the food chain. For example, bacteria in the soil are primary producer microorganisms; they transform organic material to make it available for small individuals. A soil worm is a primary consumer microorganism which will feed from this organic material transformed by the bacteria. The worm will then produce food and will be food for herbivores to continue with the flow of energy in the food chain.
