(1a).

A) To determine the moisture content in the soil

(1b)

I – Evaporating dish

II- Garden soil

III-Tripod stand.

IV- Bunsen burner

 

1c) i) Wright of the dried soil =

80-35 =45g.

ii) Weight of water lost =

60-45 =15g.

 

iii) percentage of water lost from

the soil

= Mass of water wafer/ Mass of fresh soil. X 100/1

= 18.75%

 

(1d) 1 Rainfall

2) condensation

(3) precipitation

======================

 

2a) Area of farmland 1/2( 70+90) 40

= 1/2 (160) x 40

= 80×40

= 3200m^2

 

 

2b) The Spacing will take an area of 4*4 = 16 m^2

The number of banana plants in the farmland

= Total area of farm land DIVIVED BY Area taken by each banana

 

i.e = 3200m^2/16m^2

= 200

 

2ci) I. Raging, pole

II. Pins, peg

2cii)

Uses of I

i)for making stating

ii)for making straight linea

Uses of II

i)for making off chain length as measured

ii)for making stating

 

2ciii)

All the equipment should be clean after use

======================

 

3a) Ageratum Conizoides

 

3b) I Flower

II. Flower stalk

III. heat

 

3c).1. Mechanically by the use 4

Mower or plough

2. Manually by cutlass

3. By the use of chemicals

4. Physically by using cutlass

 

Methods of Dispersal

1. Wind

2. man

3 Light

 

3d) Economic importance of weed

1. It serves as feed for livestock.

2. Some weeds are useful as food for humans.

3. It help in checking soil

erosion

4. It serve medicinal purpose

===========================

 

4a) I- Duct

II- Testis

III- Penis

VI- Seminal Viscule

V – penis coat

IV- epididemis

 

(b) Duct- it moves the sperm cell

from testis, to penis

 

– Testis- It helps to stoxe the sperm

cells of spermatozoa.

 

– Penis- It is used to introduce the

Sperm cell into the female

 

– Seminal Visicule- It helps to form

a fluid in which the Sperm cells can move.

 

– Penis Coat: It protects the penis

 

– epididemis: it produces the

sperm calls.

 

4c) i) castration

4cii)- Duct will be cut

– the epidermis will be removed
