Answer/Explanation
Characteristics of Life Present in Viruses:
- has a defined boundary - viruses are made up simply of genetic material surrounded by a<u> protein capsid </u>and sometimes a lipid membrane
Characteristics of Life Absent in Viruses:
- made up of one or more cells - one of the main arguments for why viruses are not living is that they are <u>not cellular</u>
- uses energy - this is a tricky one. They don't use or produce their own energy. However, in order to reproduce they do hijack the host cells and <u>steal energy</u> from them in order to reproduce
- exhibits growth and development - although viruses do <u>reproduce</u>, the individual viral particles do not exhibit growth or development
- possess internal organisation - other than the fact they ahve genetic material, the inside of a virus does not contain internal organization like a cytosol, instead conssiting of the bare minimum amount of proteins to survive
- eliminates waste - since they do not have their own metabolism, they have no waste to eliminate
Answer:
a) 3H2 + N2 = 2NH3
b) 2K + 2H2O = 2KOH + H2
c) 2Al + Fe2O3 = Al2O3 + 2Fe
d) Same as c)
e) Ba(OH)2 + 2HBr = BaBr2 + 2H2O
f) CaCO3 = CaO + CO2
Well, based on evaporation I would say the heat is coming out of the water. Unless the temperature of the heat has something to do with it. Otherwise, I'm positive the heat is coming from the water.
How many cycles happen in a given unit of time is called a wave's frequency.
Barrier islands typically have sand in the beach zone and dune field, and mud in the back-barrier. Overwash deposits sand in the back-barrier.
Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. ... When a storm such as a hurricane digs an inlet through the spit a barrier island is formed.
