The sentence states that there are two aspects of coping with drought: emergency measures and other types of measures. Emergency measures are immediate responses to a crisis. The opposite of this would be long-term or planned strategies to mitigate future occurrences of drought. Routine refers to regular, long-term measures taken to prevent or manage drought in a structured way.

parallel; occurring or existing side by side

scheme; a large-scale systematic plan or arrangement for attaining some particular objective or putting a particular idea into effect.

Effective; successful in producing a desired or intended result.

The process of a substance changing from solid to liquid upon heating is called fusion. It happens when the temperature reaches the melting point, allowing particles to gain enough energy to move freely as a liquid.

- Alpha radiation consists of helium- He\(^{4}_{2}\) 2 Alpha decay --> 2 X He\(^{4}_{2}\) = Element\(^{8}_{4}\) - Beta particles are high energy electrons- e\(^{0}_{-1}\) 3 Beta particles --> 3 X e\(^{0}_{-1}\) = Element\(^{0}_{-3}\) - Gamma rays are waves of electromagnetic energy, or photons. the mass and atomic number of the resulting element = U\(^{235}_{92}\) - Elements( \(^{8}_{4}\) + \(^{0}_{-3}\) ) --> Element\(^{227}_{91}\)

The salt that is slightly soluble in water is CaSO\(_4\) (Calcium Sulfate). AgCl (Silver Chloride): This is considered very slightly soluble or nearly insoluble in water due to its strong ionic bonds. Na\(_2\)CO\(_3\) (Sodium Carbonate): This is highly soluble in water as it is a sodium salt. PbCl\(_2\) (Lead Chloride): While considered slightly soluble, it has a lower solubility compared to CaSO4.

In the thermal decomposition of potassium chlorate ((KClO\(_3\) ), manganese(IV) oxide (MnO\(_2\)) acts as a catalyst. A catalyst functions by providing an alternative reaction pathway with a lower activation energy (the "energy barrier"). Because this barrier is lowered, more reactant particles possess sufficient kinetic energy to undergo successful collisions at a lower temperature, allowing the reaction to proceed efficiently with only moderate heat. While option C is also a characteristic of catalysts, option D specifically explains how the catalyst enables the use of moderate heat rather than the high temperatures required for the uncatalyzed reaction

In the laboratory, nitrogen monoxide (NO), also known as nitric oxide, is commonly prepared by the reduction of dilute nitric acid with copper, resulting in the formation of copper(II) nitrate, water, and nitrogen monoxide gas. The chemical equation for this reaction is: 4HNO\(_3\) + Cu → Cu(NO\(_3\))\(_2\) + 2NO + 4H\(_2\)O

Effective; successful in producing a desired or intended result.

Individuals with blood type AB positive are usually called universal recipients while individuals with blood type O are usually called universal donors.
