\nAnswer:<\/strong> The unicellular organism is Amoeba sp.<\/p>\n\n
\nAnswer:<\/strong> In humans, amoeboid movement is found in macrophages and white blood cells. These cells show amoeboid movement to engulf antigens or microbes and short-distance immigration in circulatory fluid.<\/p>\n
\nAnswer:<\/strong> Different tubular organs in the human body consist of ciliated epithelial lining. They show ciliary movement.<\/p>\n
\n<\/strong>Answer:<\/strong> These cilia prevent the entry of pathogens and dust particles inhaled with air, within the body.<\/p>\n

\nAnswer: Two proteins which help in muscle contraction are\u2014<\/strong><\/p>\n\n
\n
\nAnswer:<\/strong> The light band of muscle fibre is known as the isotropic band or l-band. This band is formed of longitudinal and parallel actin proteins. The dark band is known as the anisotropic band or A-band.<\/p>\n
