17th Century: - Antonie van Leeuwenhoek (1632-1723) - Bacteria (1676) - Yeast (1680) - Protozoa (1676) - Robert Hooke (1635-1703) - Cells in cork tissue (1665) 18th Century: - Otto Friedrich Müller (1730-1784) - Protozoa (1773) - Algae (1777) - Carl Linnaeus (1707-1778) - Classified microorganisms into genera and species (1753) 19th Century: - Christian Ehrenberg (1795-1876) - Bacillus subtilis (1835) - Staphylococcus aureus (1839) - Felix Archimède Pouchet (1800-1872) - Protozoa (1837) - Louis Pasteur (1822-1895) - Microorganisms responsible for fermentation and spoilage (1850s) - Ferdinand Cohn (1828-1898) - Bacteria (1872) - Nitrobacter (1872) - Robert Koch (1843-1910) - Bacillus anthracis (1876) - Mycobacterium tuberculosis (1882) - Sergei Winogradsky (1856-1953) - Nitrogen-fixing bacteria (1890) - Martinus Beijerinck (1851-1931) - Viruses (1898)

From 17 to 19 century blood coruscles striated muscles , human spermatozoa in 1677, protozoa in 1674, bacteria in 1683 and rotifers are discovered

I was wondering why Antonie van Leeuwenhoek is called the 'Father of Microscopy' when Zacharias Janssen invented the microscope. I found out that it's because Van Leeuwenhoek made important improvements and discoveries that helped develop the field of microscopy.

Frog scientific name is Anura

Sir Thanks for uploading the lecture . It really helped me understand the material, especially since our new teacher's (kanwal) explanations have been unclear.

Robert Hooke discovered cells in 1665. He called them 'cellulae'because they looked like small rooms.

Question: Describe the reasons how animal species becomes endangered due to human activities e.g : Houbara bustard , blind dolphin and Marco polo sheep. Answer: Human activities have led to the endangerment of many animal species, including the Houbara Bustard, Blind Dolphin, and Marco Polo Sheep, due to: 1. Habitat destruction and fragmentation: - Houbara Bustard: Habitat loss due to urbanization, agriculture, and infrastructure development. - Blind Dolphin: Entanglement in fishing nets and habitat degradation due to pollution and dam construction. - Marco Polo Sheep: Habitat loss and fragmentation due to infrastructure development and mining. 2. Overhunting and poaching: - Houbara Bustard: Overhunting for its meat and feathers. - Blind Dolphin: Entanglement in fishing nets and hunting for its meat. - Marco Polo Sheep: Overhunting for its trophy value. 3. Pollution: - Blind Dolphin: Pollution from industrial and agricultural runoff affects its food supply and habitat. - Marco Polo Sheep: Pollution from mining activities affects its habitat and food supply. 4. Climate change: - All three species: Climate change affects their habitats, food supply, and migration patterns. 5. Human-wildlife conflict: - Houbara Bustard: Conflict with farmers due to crop damage. - Marco Polo Sheep: Conflict with herders due to competition for grazing land. 6. Inadequate conservation efforts: - Lack of effective protected areas, enforcement, and community engagement. These human activities have cumulatively pushed these species towards endangerment, highlighting the need for urgent conservation action to protect their habitats, reduce human-wildlife conflict, and address climate change.
