Explanation

The third stanza of the Shakespearean sonnet is a quatrain. A Shakespearean sonnet consists of three quatrains (four lines each) and a final rhymed couplet. The quatrain presents a separate idea or example, and the couplet provides a summary or a different take on the previous lines.

Correct Answer: D. \(\frac{15}{16}\)

Explanation

P(at least one head) = 1 - P(4 tails)

Let \(p = \frac{1}{2}\) = probability of head and \(q = \frac{1}{2}\) = probability of tail.

\((p + q)^{4} = p^{4} + 4p^{3}q + 6p^{2}q^{2} + 4pq^{3} + q^{4}\)

P(4 tails) = \(q^{4} = (\frac{1}{2})^{4} = \frac{1}{16}\)

P(at least one head) = \(1 - \frac{1}{16} = \frac{15}{16}\)

Correct Answer: B. The civil service

Correct Answer: A. motivate

Explanation

dissuade; persuade (someone) not to take a particular course of action. synonyms; discourage, deter, prevent

Correct Answer: B. 6.8

Explanation

\(\bar{x} = \frac{2 + 4 + 7 + 8 + 9}{5} = 6

variance = \(\frac{34}{5}\)

= 6.8

Correct Answer: B. Yakubu Gowon

Explanation

a)Description of life cycle of the variegated grasshopper

-Adults male and female mate

-The female lays eggs underneath leaves

-The eggs hatch into nymphs around October/onset of dry season

- During the fourth instar stage, they migrate into the farm and continue to feed on leaves up to the adult stage

- It undergoes incomplete metamorphosis.

(b) Ways through which diseases are spread on crop farms

- Harbouring of pathogens by weeds

- Contaminated irrigation water

- Rain splash

- Insect vectors/pest infestation

- Use of infected planting materials Wind dispersal of pathogens

- Use of contaminated tools equipment

- Uncontrolled movement of visitors to the farm

- Animal dispersal of pathogens especially during feeding

- Dews

- Soil/soil borne pathogens

(c) Characteristics of a good layer

- Presence of short beak

- Large, bright red comb

- Soft and pliable abdomen

- Broad breast bone

- Broad and square head

- Large, oval, moist, warm and smooth vent

- Glossy plumage/feather

- Bright eyes

- Smooth and lean face

- Absence of cannibalistic behaviours

- Broad, flexible pelvic bones

- Dilating cloaca - Soft

Correct Answer: D) lymphocytes

Explanation

This Biology question is asking us to identify which of the options listed is not formed in the bone marrow. The options listed are platelets, basophils, granulocytes, and lymphocytes. Platelets are small cell fragments that help in blood clotting. Basophils and granulocytes are types of white blood cells that help the body fight infections. Lymphocytes are also a type of white blood cell that plays a key role in the body's immune system. The correct answer is option D, lymphocytes. Lymphocytes are actually formed in the lymphoid tissue and not in the bone marrow. It's important to note that bone marrow is responsible for producing many other types of blood cells, including red blood cells, white blood cells, and other types of immune cells. These cells are important for maintaining a healthy immune system and ensuring the proper functioning of the body. In summary, the correct answer to this Biology question is option D, lymphocytes. Lymphocytes are not formed in the bone marrow, but rather in the lymphoid tissue. Bone marrow is important for producing many other types of blood cells that are necessary for a healthy immune system.
