Pollination is a method where pollen grains are picked from an anther, which is the male part of a flower and transferred to the flower’s female part called the stigma. To make the pollination work successfully, the pollen grains must be transferred from the same species of flower.

A fraction is any number of the form a/b where both “a” and “b” are whole numbers and b≠0. On the other hand, a rational number is a number which is in the form of p/q where both “p” and “q” are integers and q≠0. Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. An integer can be written as a fraction simply by giving it a denominator of one, so any integer is a rational number.

Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3)(x - 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. A common method of factoring numbers is to completely factor the number into positive prime factors. A prime number is a number whose only positive factors are 1 and itself. For example, 2, 3, 5, and 7 are all examples of prime numbers. Examples of numbers that aren't prime are 4, 6, and 12 to pick a few.

Metals react with acids to form salt and hydrogen gas.

Metal + Dilute acid →  Salt + Hydrogen

Metals react with dilute hydrochloric acid to give metal chloride and hydrogen gas. Example - Magnesium reacts violently with dilute hydrochloric acid to form magnesium chloride and hydrogen.

Metals react  with  water to produce metal oxides with the release of hydrogen gas. But all metals do not react with water.

Metal +  Water → Metal oxide + Hydrogen

Metal oxides that are soluble in water dissolve in it to further form metal hydroxide.

Metal oxide +  Water → Metal hydroxide

Metals  such as  sodium  and  potassium  react  vigorously  with  cold  water  to  lead  to  evolution  of hydrogen, which immediately catches fire producing a large quantity of heat.

Metals react with acids to form salt and hydrogen gas.

Metal + Dilute acid →  Salt + Hydrogen

Metals react with dilute hydrochloric acid to give metal chloride and hydrogen gas. Example - Magnesium reacts violently with dilute hydrochloric acid to form magnesium chloride and hydrogen.

Blue Green algae are a type of photosynthetic bacteria consisting either of single cells or colonies which is also known as the Cyanobacteria. Cyanobacteria contain only one type of chlorophyll, Chlorophyll a, a green pigment. In addition, they also contain pigments such as carotenoids, phycobilin.

These bacteria grow naturally in marine and freshwater systems. They thrive in dams, rivers, reservoirs, lakes and even in hot springs. These bacteria normally look green and sometimes turns blue when scum are dying. Almost all species of these bacteria are buoyant and float on the water surface and forms floating mats.

Blue-green algae have been used for food for several centuries in Mexico and some African countries. They have been sold as a supplement in the US since the late 1970s. Blue-green algae products are sometimes used by mouth as a protein supplement and for treating high blood pressure.

• Microbes play a vital role in preparing curd from milk. Curd contains a bacterium, Lactobacillus
• Lactobacillus is a friendly-bacterium. It treats & prevents diarrhea, helps in food breakdown and absorption of nutrients.

Lactobacillus is a genus of Gram-positive, facultative anaerobic or microaerophilic, rod-shaped, non-spore-forming bacteria. Lactobacillus is the most common probiotic found in food such as yogurt, and it is diverse in its application to maintain human well-being, as it can help treat diarrhea, vaginal infections, and skin disorders such as eczema.

The Nepalese Constituent Assembly came to fruition on 24 December 2007 when it was announced that the monarchy would be abolished in 2008 after the Constituent Assembly elections; and on 28 May 2008, Nepal was declared a Federal Democratic Republic. In May 1991, Nepal held its first parliamentary elections. In February 1996, the Maoist parties declared People's War against monarchy and the elected government. ... On May 28, 2008, the newly elected Constituent Assembly declared Nepal a Federal Democratic Republic, abolishing the 240 year-old monarchy.

The process of removing a plant from the place where it has been growing and replanting it in another is called transplantation.
Tomato and paddy are examples of crops grown by transplantation.
