Living things grow and change through the process of cell division, ormitosis. In organisms composed of more than one cell, mitosis either repairs damaged cells or replace older ones that have died. Additionally, multicellular organisms grow larger in size by increasing the number of cells in the...
在提到衰老背后的原因时,教授提到第一种生物钟理论:First,you have the biological clock category—theories in this category assert that all organisms have a sort of internal biological clock,that they are sort of genetically programmed to age in a certain age at a certain rate.即衰老是由生物内在...
Paragraph 5: To measure continuous darkness, a plant needs two things: some sort of metabolic clock to measure time (the duration of darkness) and a light detecting system to set the clock. Virtually all organisms have an internal biological clock that measures the time even without environmental...

What do all complex multicellular organisms have in common? Organisms: An organism is considered a living form, such as an animal, plant, fungi, or bacteria. As of this point, Earth is the only planet in the Solar System that contains a variety of organisms from tiny, unicellular organisms...
What three structures are found in the cells of all organisms, both prokaryotic and eukaryotic? What cells have a nucleus and membrane bound organelles? Prokaryotic cells lack which of these? A. nucleolus B. nuclear membrane C. membrane bound by orga...
Virtually all organisms have an internal biological clock that measures the time even without environmental cues. In most organisms including plants, the biological clock is poorly understood, but we know that the environmental cues, particularly light, can reset the clock. How do plants detect ...
Professor: Many organisms have developed the ability to survive in harsh environmental conditions: extreme heat or cold, or very dry conditions. 教授:许多生物已经发展了在恶劣环境中生存的能力:酷热、严寒,或者非常干燥的环境。 Like plants in the desert. ...
Do fungi have meristems? Is fungi a pioneer species? What do all complex multicellular organisms have in common? What do amoeba and paramecium have in common? What are smut fungi ? How do they affect plants ? How are the divisional names for fungi derived?
All organisms are composed of cells (cell theory). Species The visible form of each of the elements of consecrated bread and wine in the Eucharist. Organism An individual form of life, such as a bacterium, protist, fungus, plant, or animal, composed of a single cell or a complex of ...
