### activity | measurement:

Titration
* are tests where a substance reacts with something else in specific proportion.
* common method of determining the amount or concentration of an unknown substance.
* procedure used for measuring the concentrations of substances in a solution.
* qualitative analysis

Viscometry
* is another method to measure myosin-actin binding in solution.
* sub-set of rheometry, devoted to measuring only the viscosity of a fluid.

Waist measurement
* correlates with abdominal fat and is used for the second measurement of obesity.
* is another way to estimate how much body fat a person has.

Weight measurement
* Most weight measurements are in kilograms or grams.
* is how much something weighs, in pounds and ounces.

Mental activity
* determines the moral qualities that people, often unwittingly, display.
* helps keep the brain in shape.
* is also extremely important when a person is ill
  - as important as physical activity
  - the supreme suffering

Meristematic activity
* can spread between the bundles so that the cambia become united.
* spreads laterally until the entire circumference of the organ is encompassed.

Metabolic activity
* Metabolic activities are done by organelles.
* Some metabolic activities produce warmth.

Microbial activity
* consumes the nitrogen and other contaminants in the wastewater.
* is affected by the carbon to nitrogen ratio of the organic waste
  - predominate in soils
  - very rapid and little organic matter accumulates in the soil
* occurs most rapidly in thin water films on the surface of organic materials
  - on the surface of particles

Military operation
* is an activity
* occur in peace and war.
* take places.

Mimicry
* Much mimicry is based in color and visual pattern.
* is imitation.

### activity | mimicry:

Mullerian mimicry
* involves resemblances between different distasteful species.
* is when two insects that are BOTH unappealing to predators look the same.
* occurs when the mimic is also well-defended.

### activity | mimicry:

Vavilovian mimicry
* is caused by unintentional selection by humans.
* occurs in plants where a weed comes to look like a crop plant.
+ Mimicry, Vavilovian mimicry: Ecology
  * Vavilovian mimicry occurs in plants where a weed comes to look like a crop plant. It is named after Nikolai Vavilov, a Russian plant breeder who discovered the idea. Before herbicides, weeds were plucked by hand. This has been done for thousands of years. The weeds come to look like the crop because the weeders pick those weeds which look most different. Vavilovian mimicry is caused by unintentional selection by humans.

Vavilovian mimicry is caused by unintentional selection by humans. The weeds that survive pass on their genes. Gradually, all the weeds look more like the crop plant.

Moderate activity
* keeps heart and waistline in shape.
* reduces the risk of coronary heart disease.
