Correct Answer: B. Kingdom

Correct Answer: B. rejection of fabrication

Correct Answer: B. Went away early like the dew

Explanation

(a)According to St. Luke's account, Angel Gabriel visited the virgin, Mary, who was betrothed to Joseph in Nazareth. The angel hailed (greeted) Mary as the favoured one and told her that the Lord was with her. Mary was troubled in mind because she did not quite understand that manner of greeting. The angel asked her not to be afraid, but told her that she would conceive in her womb and bear a son to be called Jesus — The son of the Most High. The Lord God would give him the throne of David and he would reign forever. Mary asked the angel how it would happen for she had no husband. The angel told her that the Holy Spirit would come upon her and the power of the most High would overshadow her, hence the child would be called Holy, the son of God. He confirmed to Mary that her cousin, Elizabeth had also conceived a son in her old age. She was then six months' pregnant. Though she had been barren before then, with God, nothing was impossible. Mary said that she was God's handmaid and wished the angel's words be fulfilled as prophesied.

(b) The Luke account differs from that of Matthew in some ways:

(i) In Matthew, an angel did not visit Mary, it was Joseph who saw an angel in a dream. The angel is not named.

(ii) Matthew alone mentions Joseph's earlier intent to divorce Mary when she was found to be pregnant. There was no such information in Luke's account.

(iii) Angel Gabriel spoke to Mary in St. Luke and she obeyed the word of God with faith.

(iv) In Matthew, there was no reference to Elizabeth as in Luke.

Correct Answer: C) a tissue

Explanation

The question is asking about a group of similar cells that work together to perform the same function. The options are enzyme, organ, tissue, and organelle. The correct answer is option C, a tissue. A tissue is a group of similar cells that work together to perform a specific function. For example, muscle tissue is made up of muscle cells that work together to contract and produce movement. Another example is nerve tissue, which is made up of nerve cells that work together to transmit messages throughout the body. Enzymes, on the other hand, are proteins that speed up chemical reactions in the body. They are not made up of cells and do not perform the same function as tissues. An organ is a structure in the body made up of different tissues that work together to perform a specific function. For example, the heart is an organ made up of muscle tissue, nerve tissue, and connective tissue that work together to pump blood throughout the body. An organelle is a specialized structure within a cell that performs a specific function. Examples of organelles include the mitochondria, which produce energy for the cell, and the nucleus, which contains the cell's genetic material. So, in summary, a group of similar cells that work together to perform the same function is called a tissue.

Explanation

(a) Meaning of soil consistency

Soil consistency is the resistance of soil to pressure and other physical manipulation

(b) Explanation on how soil properties influence crop growth

(i) Soil texture

-Determines water holding capacity of soils

-Influences air movement in the soil

- Affects root penetration

-Affects soil workability

-Has direct effect on soil drainage/infiltration

-Affects the retention of plant nutrients

(ii) Soil PH

-Generally, extreme pH values affect the activities of soil micro-organisms

-Affects the availability of plant nutrients

- Affects the solubility of certain elements which may be toxic to crops at high concentration

-Crops perform poorly outside their required pH range

-Controls cation exchange capacity (C.E.C.) of the soil

(c)(i) Methods by which soil fertility could be maintained

-Fallowing (as in land rotation)

-Alley cropping

-Crop rotation

-Mixed cropping

-Mixed farming

-Cover cropping

-Application of organic/inorganic fertilizers

- Liming

(ii) Ways in which each of the methods contributes to the maintenance of soil fertility

-Fallowing (as in land rotation)

-Deep rooted plants extract leached nutrients which will eventually be returned to the top soil

-Dead plants decompose and add humus to the soil

-Activities of soil micro and macro-organisms add organic matter to the soil under the fallow system

- Dead plants add nutrients to the soil

Alley cropping

- Through nitrogen fixation by the leguminous plants

- Litter from the trees decompose and add humus to the soil

- Litter from trees decompose to release nutrients to soil

-Litter acts as mulch to control erosion

Crop Rotation

-Crops that feed deep in the soil extract plant nutrients from below leaving nutrients in the upper layer for the surface feeders to us

-Legumes incorporated in the rotation can replenish the land

- Constant vegetation cover checks soil erosion

Liming

- Addition of lime provides basic cations e.g. Calcium and Magnesium

- Liming raises soil pH making nutrients like phosphorus more available

- Liming increases the cation exchange capacity of soils

Mixed cropping

- If leguminous plants are included, nitrogen will be added to the so and this improves soil fertility

- Crops with different rooting systems will extract nutrients from different depths of soil

Mixed farming

- Animal droppings add nutrients to the soil

- Animal droppings increase the cation exchange capacity of the soil

- The microbes in the droppings assist in the decomposition of plant remains falling on the soil

Cover crops

-Protects the soil against erosion

- Fixes atmospheric nitrogen into the soil when leguminous crops are used

-Dead leaves of plants are decomposed to increase soil fertility

-Creates conducive environment for increased microbial activities

Application of organic? inorganic fertilizers

- Increases cation exchange capacity of the soil when organic manure is applied

-Adds nutrients to the soil

-Raises soil pH when lime is applied

-Lowers the soil pH when acidulants are added e.g. pyrite. gypsum
