Answer:
- If it were true, all organisms would be complex and simple organisms would disappear
- It does not account for genetic mutations known to affect physical traits
Explanation:
Lamark's theory of evolution is that changes in the organism's physical form during its lifetime can be passed on to its offspring. In other words, he believed that children can inherit acquired characteristics from their parents.
The classic example is that he believed giraffes evolved long necks because they would stretch upwords to eat leaves from tall trees, elongating their necks, and then would pass on a longer neck to its children. Or in humans, that a body builder would make a muscular child because of their intense training!
There are a few problems with this theory:
- If we believe this theory, organisms would always be getting more and more complex and 'improved', so simple organisms would disappear.
- We know that changes to the DNA influence inherited physical characteristics, not simply continued use
A. Settling Tank - 3. A principle tool of primary sewage treatment. Lightweight solids, grease and floating particles are skimmed off the top and heavier materials sink to the bottom as sludge.
B. Trickle Filter - 4. A secondary sewage treatment system used in smaller communities. Effluent from the primary treatment slowly flows through a shallow artificial stream. The water is oxygenated as it flows over the rocks. The rocks become covered with a zooglial mass of aerobic microorganisms that break down organic matter to CO2.
C. BOD - 2. An abbreviation that stands for Biochemical Oxygen Demand. This is a measure of the total amount of organic matter that is dissolved in a sewage sample.
D. Activated Sludge System - 5. A secondary sewage treatment system used in larger communities. Effluent from the primary treatment is seeded with sludge that contains a high concentration of metabolizing bacteria and vigorously aerated. Aerobic metabolism breaks down organic matter that is dissolved in the water to CO2. Growth of microorganisms produces more sludge, which is allowed to settle out.
E. Imhoff Tank - 6. A container for the anaerobic digestion of sludge. Anaerobic bacteria ferment organic matter producing CO2, H2 and small organic acids such as acetic acid and formic acid. Then anaerobic archaea convert the small acids, CO2 and H2 to methane.
F. Floc - 1. A particle of organic matter that sinks to the bottom of a tank. These particles particles consist of little pieces of organic matter covered with microorganisms. The microbial population of the particles is a mixed community of bacteria and fungi that degrade organic compounds and protozoa that eat the smaller microorganisms. Sometimes alum is added to the sewage, this helps increase the formation of larger particles that settle out faster.
That is called desalination
Answer:
Potential Energy
Explanation:
This is the energy stored in your body, so this would be the energy you use while lifting something.
