Answer the following Read the paragraph and answer the questions given below it. Food poisoning can occur due to contamination of food by various bacteria and fungi.Clostridia are bacteria responsible for spoilage of cooked food. There are around 100 species of this bacteria viz. Clostridium tetani, Clostridium botulinum, etc. that are present either free living in soil or the alimentary canal of humans and other animals.

Read the paragraph and answer the questions given below it. The cells of the nervous tissue become excited on receiving stimuli and conduct that excitation from one part of the body to another. The cell body containing the cytoplasm and nucleus is the main part of each nerve cell. Numerous, small, branched fibres called dendrites arise from the cell body of the nerve cell. One of the fibres is extremely long, it is called the axon. Numerous nerve cells are bound by connective tissue to form a nerve. Nervous tissue is present in the brain, spinal cord and the network of nerves spread all through the body. In most of the animals, response to stimuli occurs due to the integrated functioning of the nervous and muscular tissue. Functioning of which two tissues are involved in generating a response to stimuli?
