Answer:
Cyanobacteria were photosynthetic and slowly changed the earth's atmosphere from CO2 rich to O2 rich. Photosynthetic cyanobacteria evolved by 3.5 billion years ago and greatly modified earth's atmosphere.
What do mitochondria do? Where are they found?
They harvest chemical energy from food & carry out cellular respiration, the conversion glucose to ATP. They are found in cells of eukaryotes, except a few anaerobic protozoans. The ATP generating electron transport system is embedded in the inner membrane (cristae) and chemical reactions occur in compartments between membranes.
What are the functional categories of organelles?
Eukaryotic organelles comprise four functional categories: -manufacture (synthesis of macromolecules and transport within the cell), -breakdown (elimination and recycling of cellular materials - energy processing (conversion of energy from one form to another) -support, movement, and communication (maintenance of cell shape, anchorage, and movement of organelles, and relationships with extracellular environments) All four categories work together as an integrated team, producing the emergent properties at the cellular level.
So in smaller terms, I guess eukaryotic organelles do this.
Answer:
Explanation:
Stalactites-a tapering structure hanging like an icicle from the roof of a cave, formed of calcium salts deposited by dripping water.
Stalagmites-a mound or tapering column rising from the floor of a cave, formed of calcium salts deposited by dripping water and often uniting with a stalactite.
The leaves close under various other stimuli, such as touching, warming, blowing, or shaking. ... The stimulus can also be transmitted to neighboring leaves. It is not known exactly why Mimosa pudica evolved this trait, but many scientists think that the plant uses its ability to shrink as a defense from herbivores
Explanation:
<u>Memory is essential to learning, but it also depends on learning because the information stored in one's memory creates the basis for linking new knowledge by association. It is a symbiotic relationship which continues to evolve throughout our lives.</u>
