In determining the dry weight of an organism, how would you know that it is completely dry?

• Dry it for a long period of time.

• Dry it until no more steam is produced.

• Dry it until smoke does not appear.

• Dry it at 100 degree celcius until its weight does not decrease anymore.

What is growth?

• It is the quantitative change in form in an organism over a period of time

• It is quantitative increase in size in an organism over a period of time

• It is the change in the degree of specialization of tissues

• It is a measure of an increase in size of an object

The figure shows the growth phases of an organism. Describe what happen during log phase?

• Cells are still dividing but at a rate replacing the cells that have died

• Growth slow down because limited by internal or external factors

• The fastest organism growth

• Organisms is trying to adapt to the new environment

What is /are the disadvantages of using the wet mass of an organism to measure growth

I. the measurement is not accurate

II. water content in the organism is inconsistent

III. it is used only to measure organisms living in water

• I only

• I and II only

• II and III only

• I, II and III

Growth:

Increase in size, weight and number of cells

• True

• False
