Which of the following statements is incorrect?

Metals usually combine with oxygen to form basic oxides
Metals generally have low melting and boiling point
Metals are good conductors of heat and electricity
Non - metals are generally non - malleable and non sonorous

Correct Answer

A. Metals generally have low melting and boiling point

Explanation

Metals generally have high melting and boiling points. This is because the metallic bond between metal atoms is strong, requiring a large amount of energy to break the bonds and change the state of the metal from solid to liquid or gas.

In the diagram O, is the centre of a circle.AE + EB = CE + ED. OP ^ AB and OQ ^ CD then true relation between OP and OQ is -

OP > OQ
OP < OQ
OP = OQ

Correct Answer

A. OP = OQ

Explanation

Since OP is parallel to AB and OQ is parallel to CD, we can conclude that OP and OQ are equal in length. This is because, in a circle, any line passing through the center and perpendicular to a chord bisects the chord. Therefore, OP = OQ.

Tissue that helps in conduction of food is:

Xylem
Phloem
Collenchyma
Chlorenchyma

Correct Answer

A. Phloem

Explanation

Phloem is the tissue responsible for the conduction of food in plants. It transports sugars, amino acids, and other organic molecules from the leaves (where they are produced) to other parts of the plant, such as the roots, stems, and fruits. Phloem consists of sieve tubes, companion cells, fibers, and parenchyma cells, all working together to facilitate the movement of nutrients throughout the plant. Xylem, on the other hand, is responsible for the conduction of water and minerals. Collenchyma and chlorenchyma are types of plant tissues that have different functions, but they are not involved in the conduction of food.
