Explanation

Alkanols, also known as alcohols, can undergo oxidation reactions with strong oxidizing agents like acidified potassium dichromate (K₂Cr₂O₇). However, not all alkanols can be oxidized by this reagent. The reactivity of an alkanol in oxidation reactions depends on the type of alcohol: primary (1

(a). The characteristics of Northern Guinea Savanna are:

(i) It has bare soil with scanty trees.

(ii) Has long twisted roots to facilitate the absorption of water and mineral salts.

(iii) Possesses thick barks which enable it to withstand harsh weather, e.g. fire and intensive sunlight.

(iv) Has twisted and gnarled trunks, which enable it to resist fire and excessive transpiration.

(v) Availability of herbivorous animals such as zebra, squirrel, antelope, grasscutter etc.

(vi).Availability of perennial grasses that grow in tufts and resist fire.

(vii) Presence of underground stems, e.g. spear grass which make the plants to be able to survive, after long period of dry season or fire out break.

(viii) Temperature is usually above 18°C throughout the year.

(ix) Trees shed their leaves during the dry season and this enables them to conserve water.

(b)Aim: To estimate the density of a plant species using quadrat sampling technique (a method of studying plant species).

Method: A quadrat is a rectangular frame which is constructed from wire or wood of known dimension. Before usage, mark the area where the species to be measured occurs. Then throw the quadrat to land randomly on any part of the marked off area. Note the area covered at each landing of the quadrat. In the process, each species of plant is counted and recorded. To determine the density, calculate the average frequency of the plant species as the number of times the plant species occurs divided by the total number of quadrat throws made.

Formula= Number of times plant species occurs

Total number of quadrat throws made

Finally, divide the average frequency by the area of the quadrat =

Average Frequency

Correct Answer: C) Azariah

Explanation

The question is asking to identify the priest who confronted Uzziah in the temple. The options are Zadokaul, Phineas, Azariah, and Aaron. The correct answer is option C, Azariah.

According to the Bible, Uzziah was a king of Judah who became arrogant and tried to burn incense in the temple, which was the duty of the priests. Azariah, who was also a priest, along with 80 other brave priests, confronted Uzziah and warned him not to do this as it was not his duty.
