Answer:
its a strong acid to be exact
Explanation:
The part that is not the conducting portion of the respiratory system is the alveoli, which is in option D, as this is not a part of the conducting portion but a part of the respiratory system. So, option d is correct.
The alveoli are small, thin-walled sacs located at the end of the bronchioles in the lungs. They are responsible for gas exchange, where oxygen is taken up from the inhaled air and carbon dioxide is released into the exhaled air. While the alveoli are an essential part of the respiratory system, they are not considered part of the conducting portion. Instead, they are part of the respiratory portion, where gas exchange occurs. So, option d is correct.

C.skin
D.alveoli
Answer:Which is not part of the conducting portion of the respiratory system? The epithelial lining of the oropharynx and the superior larynx (vocal cords) is nonkeratinized stratified squamous. In general, respiratory zone structures are lined with a thicker mucosa than conducting zone structures.

Answer:
Independent variable: The fertilizer given
Dependent variable: Daily plant growth
Constants: How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
Explanation:
Independent variable of an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment where Sherri wanted to test what fertilizer worked best on her tomato plants. She used 4 different brands of fertilizer. Hence, the FERTILIZER is the independent variable
On the other hand, the dependent variable is the variable that is measured in the experiment. It is the variable that responds to the independent variable. In this experiment, the DAILY PLANT GROWTH is the dependent variable.
Constants are variables that are kept unchanged or constant throughout the experiment. In this case, the constants or controlled variables are: : How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
The independent variable in Sherri's experiment is the type of fertilizer used. The dependent variable is the daily growth of the plants. The controlled variables include the type of plant, the amount of sunlight received, and the amount of water given daily.
In this experiment, the independent variable is the fertilizer given to each plant. This is because the type of fertilizer is what is being changed or manipulated in this experiment to observe the potential changes or effects on the plants.
The dependent variable in this scenario is the daily plant growth. It is called 'dependent' because its value might change depending on the effect of the independent variable (the fertilizer).
The controlled variables for the experiment are the type of plant, how much sunlight the plants receive, and how much water they receive daily. These are conditions that were kept the same for each plant to ensure that the only difference between the plants was the type of fertilizer used.

Pollution can be defined as the introduction of biological matter, particulate and chemicals that are harmful to humans, plants and animals. pollution can also cause damage to natural environment. However, animal digestion can cause natural air pollution by releasing methane which is a greenhouse gas.
Answer: True
Explanation: Human beings pollute the air by undergoing several activities like burning of fossil fuels, combustion of the fuels by the automobiles, emission of hazardous gases from industrial and agricultural wastes. But human beings are not only responsible for this pollution but animals like cattles (cow, baffallo) excreate a large amount of dung which is a source of greenhouse polluting gas called as methane.
