Correct Answer: C. diffusion

Correct Answer: D. Cambium

Correct Answer: D. white matter

Correct Answer: D. variation

Correct Answer: B) Atoms, molecules, organelles, cells, tissues, organs, systems, organism

Explanation

This Biology question is asking about the order of hierarchical organization of living organisms. The options are presented in a sequence of different levels of organization, starting from atoms and ending with the entire organism. Option A lists atoms, molecules, compound, cells, tissues, organs, systems, and organism as the order of hierarchical organization of living organisms. However, the correct answer is Option B, which lists atoms, molecules, organelles, cells, tissues, organs, systems, and organism. Organelles are structures within cells that carry out specific functions, such as mitochondria for energy production. Cells are the basic unit of life, and tissues are groups of similar cells that work together to perform a specific function, such as muscle tissue. Organs are groups of tissues that work together to perform a specific function, such as the heart. Organ systems are groups of organs that work together to perform a specific function, such as the cardiovascular system. Option C lists atoms, elements, molecules, cells, tissues, organs, systems, and organism as the order of hierarchical organization of living organisms. Option D lists atoms, molecules, elements, cells, tissues, organs, organ systems, and organism. These options are not correct as they list elements instead of organelles and include compound instead of elements. Overall, the correct order of hierarchical organization of living organisms is atoms, molecules, organelles, cells, tissues, organs, systems, and organism.

Correct Answer: B) displacement of digested food

Explanation

Air pollution can have various negative effects on living organisms and their environment. The given question asks which effect of air pollutants is not correct. The options provided are A, B, C, and D. Option A states that air pollutants can lead to the formation of carboxyl haemoglobin. This is correct as carboxyl haemoglobin is formed when carbon monoxide, a common air pollutant, binds with haemoglobin in the blood. This reduces the amount of oxygen that can be transported in the blood, leading to health problems. Option B suggests that air pollutants can displace digested food. This is incorrect. Air pollution does not affect the digestion or displacement of food in the body. The digestive system and respiratory system are separate and distinct from each other. Option C states that air pollutants can lower plant yield. This is true as air pollutants can affect plant growth and reduce crop yield. This is because plants require clean air to carry out photosynthesis which is crucial for their growth. Option D suggests that air pollutants can damage breathing organs. This is correct as air pollutants can cause respiratory problems and damage the lungs, leading to chronic respiratory diseases such as asthma, bronchitis, and chronic obstructive pulmonary disease (COPD). Therefore, the correct answer to the question is option B, which states that displacement of digested food is not an effect of air pollutants. In summary, air pollution can have various negative effects on living organisms and their environment. These effects include the formation of carboxyl haemoglobin, lowering plant yield, and damaging the breathing organs. However, displacement of digested food is not an effect of air pollutants.
