New fungal colonies are formed bygermination of spores in hot and dry places.

Many organic substances are negatively charged e.g., acetic'acid, while others are positively charged e.g., ammonium ion. An aminoacid under certain conditions would have both positive and. negative charges simultaneously in the same molecule.Such a form of aminoacid is called.

Questions based on paragraph : Sound is propagated in a material medium in the form of compression and rarefactions. One compression and one rarefaction together form one cycle of the sound wave. The number of cycles produced per second is called as frequency. A tuning fork is a two-pronged device which vibrates to produce sound when struck. The frequency of a tuning fork is decided by the dimensions of the prong and the material used for making the fork. When these sound waves reach ears of listener, his ear-drum vibrates. Accordingly specific signals are conveyed to the brain and the listener gets a sense of hearing sound. : If a sound wave consists of ten compressions and ten rarefactions, then how many cycles of wave will it form?

Two coins are tossed simultaneoulsy . Condition for event P : To get head on both coins . Conditon for event Q : To get tail on first coins.

Read the following paragraph and answer the questions based on it. Rhizobium produce nitrogenous compounds from atmospheric nitrogen. However, for this process of nitrogen fixation, they need leguminous plants like beans, sweet pea, soyabean, etc. as ‘host’. Rhizobium living in root nodules supply nitrates, nitrites and amino acids to that plant and in exchange get energy in the form of carbohydrates from it. Such a mutually beneficial relationship is called symbiosis. Beans and pulses are rich in proteins due to the nitrogenous compounds made available by Rhizobium. After harvesting a leguminous crop, the left-over roots and other plant parts are deliberately dumped in farm soil to maintain its bacterial population. The use of Rhizobium has helped to reduce the use of chemical fertilizers and thereby their adverse effects. It has also helped to reduce expenses on fertilizers and thus works to the benefit of farmers. How do the soil conditions improve by Rhizobium?
