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

Grasshopper
Fish
Human organ
Which statement about limited growth curve is correct?
Continue to grow until they are restricted by environment factors
Growth is complete when the organism achieves its maximum size
The growth of an organism within the organs grow at the same rates with the other parts of the body
Shows the correlation between the growth and development of the organism
Which statement about unlimited growth curve is correct?

What does an absolute growth curve show?
It shows the actual growth of the organism
It shows the rate of growth of the organism
It shows the lifespan of an organism
It shows the amount of growth per unit time
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
Caused by extreme conditions, such as a drought.
Hibernation
Dormancy
Migration
Happens during the winter when food is scarce.

Migration
Dormancy
The only valid method of measuring the true growth of seedlings is by determining the increase in ....
fresh weight
dry weight
length
volume
from the graph it can deduced that
a fresh weight of germinating seeds increases steadily with time.
the endosperm of a monocot seed does not provide sufficient food reserves for healthy growth
the weight of a seed consists mainly of water stored within the seed
the embryo uses up the food store of the seed for germination and the following rapid growth phase
