Write down the major characteristics of kingdom Plantae and kingdom Animalia?

Comparison of Kingdom Plantae and Kingdom Animalia Characteristics Kingdom Plantae Kingdom Animalia Cell Type Eukaryotic Eukaryotic Cell Wall Present (made of cellulose) Absent Mode of Nutrition Autotrophic (photosynthesis) Heterotrophic (ingestion of food) Chlorophyll Present (in chloroplasts) Absent Movement Generally stationary (except some, like Chlamydomonas) Usually motile (capable of movement) Response to Stimuli Slow response to … Read more

Explain the three-domain system of classification.

The three-domain system was introduced by Carl Woese based on molecular evidence, especially ribosomal RNA sequencing. The three domains are: Bacteria: Prokaryotic, have peptidoglycan cell walls, reproduce by binary fission (e.g., E. coli). Archaea: Prokaryotic but distinct from bacteria, lack peptidoglycan, live in extreme environments (e.g., Methanogens). Eukarya: Eukaryotic, includes Protists, Fungi, Plantae, and Animalia … Read more

Explain the use of the biological method to understand the spread of malaria.

Observation – Malaria is more common in areas with stagnant water. Hypothesis – Mosquitoes breed in water and spread malaria. Experimentation – Scientists monitored mosquito life cycles and infection rates. Data Collection – Mosquitoes carrying Plasmodium were linked to infected patients. Conclusion – Mosquito control (e.g., insecticides, nets) reduces Related Questions: How is biology related … Read more

How is the biological method applied to find the cause of malaria?

1. Observation – Malaria cases were common in swampy areas. 2. Hypothesis – Malaria is transmitted by mosquitoes. 3. Experimentation – Ronald Ross studied mosquitoes feeding on malaria patients. 4. Data Collection – Plasmodium was found in mosquitoes’ stomachs. 5. Conclusion – Malaria is caused by Plasmodium and spread by mosquitoes. 6. Theory Formation – … Read more

Discuss the biological method of study and its applications.

The biological method follows structured steps: 1. Observation – Identifying a problem (e.g., malaria spread in a region). 2. Hypothesis Formation – A possible explanation (e.g., mosquitoes transmit malaria). 3. Experimentation – Testing the hypothesis (e.g., observing infected and healthy individuals). 4. Data Collection – Recording results (e.g., blood samples). 5. Conclusion – Confirming or … Read more
