Correct Answer: D. unfaithfulness

Explanation

The Israelites displayed unfaithfulness following the negative report of the spies about Canaan because they doubted and murmured against God's promises and leadership through Moses. They expressed a lack of trust in God's ability to fulfil His promises to bring them into the promised land, showing a lack of faith and loyalty towards God despite witnessing His previous signs and wonders. This unfaithfulness led them to despair and a desire to return to Egypt, questioning God's plan for them and ultimately disobeying His commands. (Numbers 14)

Explanation

(a) The second term is a d= x - 1 while the fourth term is a + 3d = x + 1. Subtracting the second tam from the fourth term yielded 2d = 2 so that d = 1.

(b). Substituting for d in the expression for the sixth term to get a + 5 = 7 and solving for a to obtain a = 2.

(c). Substituted for a and d in the expression for the second term and found x = 2 + 1 + 1 = 4.

Correct Answer: C. the drink was free of charge

Explanation

(a) Reasons why animals move from place to place:

(i) To search for food.

(ii) Escape predators.

(iii) Find mates for reproduction.

(iv) To disperse/reduce competition/overcrowding by moving to new locations.

(v) Avoid dangers. (vi) Find new and favourable habitats.

(b) Function of structures found in plant:

(i) Epidermis: For protection of inner cells from injury, infection, prevent excessive loss of water.

(ii) Phloem: Responsible for the transportation of enzymes/hormones; manufactured food.

(iii) Sclerenchyma: Strengthens the stem/provide mechanical support; makes plants flexible.

(c) Examples of organism:

(i) Parasitic plants: Viscum/mistletoe; dodder plant/Cassytha; Cuscuta; phytophisor; peronospora.

(ii) Saprophyta: Bacteria; fungi/Rhizopus; Mucor, Aspergillus; Mushroom/Agaricus.

(d) adaptive features of plants in salt water swamps: -

• Succulent stem/root/store water; to dilute the salt.
• Presence of pneumatophores/breathing roots; for breathing atmosphere air/oxygen.
• Presence of stilt roots; for anchorage.
• Viviparous seedling; to ensure their survival/continuity.
• Some a secrete excess salt into swamps; to maintain balance of body salt.

(e) Factors that: (i) Increase population density:

• Increased birth rate/natality
• immigration, increase a food availability
• low mortality rate.

(ii) Decrease population density:

• Emigration
• diseases
• drought/famine/natural disaster
• high mortality rate
• low natality rate.

(f) Ways modern agricultural activities may threaten the survival of species: -

• Deforestation/commercial farming destroys habitats of species.
• Destruction/loss of natural vegetation/habitat.
• Over hunting of games reduces population of species.
• Improper/Indiscriminate application of chemical/salinizationteutrophication, pesticides destroys species.
• Lack of afforestation practices.
• Inappropriate fishing methods threaten the population of fish.

(g) Reasons why mitosis is important to living organisms: -

• It ensures growth.
• Involved asexual ,reproduction e.g. fission, budding, spore formation.
• Ensures retention of diploid condition. Repair of tissues within organisms.
• Transfer of exact genetic code from parents to offspring.

(h) Causes of food spoilage: -

• Microbial attacks by bacteria or fungi/or saprophytic action.
• Pest attack by beetles, weevils that destroy stored grains.
• Improper storage which results in deterioration and spoilage of stored foods.
• Destruction of stored fruits and meat by some worms, usually larva of flies.
• Delay in transportation due to bad roads.
• Lack of market facilities for the commodity.
• Poor harvesting method/damage to fruits/ vegetables/tubers during harvesting.
• Poor unhygienic handling/processing/exposure to dust.
• Storage in contaminated containers.
• Use of contaminated water to wash food.

Correct Answer: B. have had

Correct Answer: C) infidelity

Explanation

The question is asking about the only justifiable reason for divorce in Jesus' teaching on the mount. The options are indolence, insubordination, infidelity and infertility.

According to Jesus' teaching on the mount, the only justifiable reason for divorce is infidelity. This means that if one partner is unfaithful to the other, then divorce is acceptable. It is important to note that Jesus did not condone divorce and emphasized the importance of marriage as a lifelong commitment.

In the context of Christian marriage, both partners are expected to be faithful to each other and uphold the sanctity of the marriage vows. Infidelity is a breach of trust and commitment, which can lead to irreparable damage to the marriage. However, divorce should always be the last resort and attempts should be made to reconcile and restore the marriage before considering divorce.

It is also important to note that there may be other extenuating circumstances that may make divorce necessary, such as abuse or abandonment. In such cases, seeking help and guidance from trusted Christian leaders or counselors is recommended.

In summary, the only justifiable reason for divorce in Jesus' teaching on the mount is infidelity. However, divorce should always be a last resort and attempts should be made to reconcile and restore the marriage before considering divorce.

Correct Answer: D. a satire

Correct Answer: B. Their father

Correct Answer: D. The vacuum space in a flask helps to reduce heat loss by radiation.

Correct Answer: D. s = \(\frac{nrp}{nr + m^2}\)

Explanation

P = S + \(\frac{sm^2}{nr}\)

P = S(1 + \(\frac{m^2}{nr}\))

P = S(1 + \(\frac{nr + m^2}{nr}\))

nrp = S(nr + m²)

S = \(\frac{nrp}{nr + m^2}\)
