Answer;

At very low temperatures

Superconductive materials are usually most effective at very low temperatures.

Explanation;

-Superconductors only work and are very effective at very low temperatures. Therefore they have to be kept very cold with liquid nitrogen or liquid helium.

-In these materials called superconductors, the electric resistance is equal to zero. At zero resistance, the material conducts current perfectly. This is somehow incomprehensible since the flaws and vibrations of the atoms is supposed to result to resistance in the conductor when the electrons flow through it.

Select the relevant adaptation exhibited by plants in their transition to land from an aquatic lifestyle.

Ainat [17]

Answer:

b, d, and f

Explanation:

The transition from aquatic lifestyle to land posses some problems to plants; these include;

Water conduction and food distribution problem
Desiccation problem

In order to firmly establish in the terrestrial environment, plants need to be able to obtain the water necessary for their metabolic activities and be able to distribute manufactured food from the various sources of production to other parts of the plant body. This is overcome by the development of conducting tissues in the form of phloem and xylem. The xylem is used to conduct water from the root to the body of the plant while the phloem is a tissue used to conduct manufactured food from the point of manufacturing round the necessary parts of the plant.

Plants also face the problem of heat and the risk of desiccation on land. The development of waxy cuticle takes care of this problem. The waxy cuticle acts as an insulator on leaves and other organs of the plant and thus protect them from desiccation.

Correct options: b, d, and f

True or false: even though ozone protects us when we are breathing it near the ground, it is harmful to us when it is high up in

Otrada [13]

Answer:

False.

Explanation:

Ozone is a triatomic gas.
Each molecule of ozone is made up of three atoms of oxygen.
Ozone is an extremely important gas in the atmosphere as it absorbs the maximum of incoming solar radiation and the ultraviolet rays of the sun.
But Ozone is an extremely reactive gas and is highly dangerous if inhaled for a longer time.
It causes damage to the lung tissue and cause respiratory ailments.
On the other hand ozone is one of the components of Photochemical smog.
Inhaling a significant amount of this gas can cause death.
Hence the given statement is False.
The correct sentence is:

Ozone protects us when it is high up in the atmosphere, it is harmful to us when we are breathing it.
