Correct Answer: B) cambium

Explanation

Monocotyledons are a group of plants that have one embryonic leaf in their seeds. This question is asking us to identify the tissue that is not found in the stem and root of monocotyledons. The options given are xylem, cambium, pith, and pericycle. Xylem is a type of tissue that conducts water and minerals from the roots to the leaves. It is found in the stem and root of monocotyledons. Therefore, option A is incorrect. Cambium is a layer of cells that divide to produce new xylem and phloem cells. It is only found in dicotyledons and gymnosperms, which are plants that have two embryonic leaves in their seeds. Therefore, option B is the correct answer. Pith is a type of tissue that stores food and water in the center of the stem. It is found in the stem of monocotyledons. Therefore, option C is incorrect. Pericycle is a layer of cells that gives rise to lateral roots. It is found in the root of monocotyledons. Therefore, option D is incorrect. In summary, the tissue that is not found in the stem and root of monocotyledons is cambium, which is only found in dicotyledons and gymnosperms.

Correct Answer: D. 245°

Explanation

Sin\(\theta\) = -0.9063; \(\theta\) = sin-1(0.9063)

\(\theta\) = -64.99 = -65°

\(\theta\) = 180° - (-65);

180 + 65 = 245°

Correct Answer: B. quite

Correct Answer: C. reducing the powers of Ibadan

Explanation

Correct Answer: C. I and II

Correct Answer: D. paying a specific amount as ransom

Explanation

Vertical component velocity Vy = Usin\(\theta\)

Time to reach maximium height = t

V = USin\(\theta\) — gt

But V at maximum height = O

.-. O = Usin\(\theta\) - gt

Hence, t = \(\frac{U sin \theta}{g}\)

But time for a projectile to reach maximum he is equal to time to return to projection plane

Time of flight T = \(\frac{2Usin \theta}{g}\)
