Can algae survive without coral? Corals are completely dependent on the symbiotic algae. They would not be able to survive without them since they can’t produce sufficient amounts of food. The zooxanthellae can provide all the nutrients necessary, in most cases all the carbon needed for the coral to build the calcium carbonate skeleton. How […]
What are the five levels of organization in our bodies from smallest to largest?
What are the five levels of organization in our bodies from smallest to largest? It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity, such as (from smallest to largest): chemicals, cells, tissues, organs, organ systems, and an organism. Figure 1.2. What is the […]
Which is more difficult to remove an electron from Mg or Na?
Which is more difficult to remove an electron from Mg or Na? It doesn’t take much energy to remove one electron from a sodium atom to form an Na+ ion with a filled-shell electron configuration. The second ionization energy of Mg is larger than the first because it always takes more energy to remove an […]

What way does speed affect stopping distance?
What way does speed affect stopping distance? The faster an object is moving, the longer the distance it takes to stop. If a vehicle’s speed doubles, it needs about 4X’s the distance to stop. If a vehicle’s speed triples, it needs up to 9X’s the distance to stop. Weight works in the same way that […]
Is CSMA CD still used?
Is CSMA CD still used? CSMA/CD is used for any half-duplex link. Short answer: The support is still present but it is generally only used when legacy equipment is connected, either hubs or very old (or embedded) network interfaces that operate at 10Mbps only and do not support autonegotiation. What is the difference between CSMA […]
Which type of boundaries can produce volcanoes?
Which type of boundaries can produce volcanoes? Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. At a divergent boundary, tectonic plates move apart from one another. Why is it important to determine […]
What is the advantage of using solvents that are denser than water in an extraction?
What is the advantage of using solvents that are denser than water in an extraction? What are the advantages of having a solvent be more dense than water when extracting an organic compound from an aqueous solution in a seperatory funnel? Two distinct layers form, allowing for easy separation. Why must the stopper of the […]
