Growth in Humans and Animals

The parameters below are used in measuring growth in humans and animals except

• height

• weight

• dry weight

• wet weight

Growth in organisms is

• increase in the number of cells

• temporary process

• reversible

• increase in density

Growth in insects is divided into

• 2 types

• 3 types

• 4 types

• 1 type only

The correct order stages of growth for complete metamorphosis is

• egg - pupa - larvae - adult

• egg - larvae - pupa - adult

• larvae - egg - pupa - adult

• pupa - egg - larvae - adult

....................undergo incomplete metamorphosis

• butterfly

• mosquitoes

• ants

• grasshopper

• Body volume increases at QR because of ecdysis.

• Body volume does not increase at PQ because of the exoskeleton

• Body volume does not increase at PQ because the insect stops growing at this stage.

• Body volume increases at QR because of air intake by insect.

In an insect, the process of removing an old exoskeleton and replacing it with a new larger one is known as

• dialysis

• haemolysis

• ecdysis

• hydrolysis

Which of the stages P, Q, R or S, is known as the exponential phase?

• P

• Q

• R

• S

Which of the following statements about the growth curve are true?

I The growth rate is the highest at Q.

II The growth rate is the lowest at S.

III The growth rate is constant at P.

IV The growth rate is zero at S.

• I and IV only

• II and III only

• I, II and III only

• II, III and IV only

Ageing, illness, lack of nutrients or space eventually leads to

• no power

• maturity

• growth

• death
