Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as they are placed within the rib cages. The lungs actually consists of elastic sacs that contract and expand for taking in and releasing air. This way oxygen is passed into the blood and carbon dioxide is taken out from the blood and passed out. This is also the main function of the lungs.

Answer:

The given statement is true.

At lungs level, trachea segmented into two primary bronchi: left primary bronchus which enters the left lung and right primary bronchus which enters the right lung.

In each lung, primary bronchi (both left and right) segmented into tertiary bronchi via secondary bronchi.

Tertiary bronchi divide to form smaller airways termed as bronchioles.

These bronchioles eventually connect with alveoli, specialized sac-like structures which form the site for gas exchange.

Thus, we can conclude that each lung is fed oxygen by a separate bronchus.

Explanation:

  1. All observations and information that scientists perceive and record are called data.
  2. A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
  3. According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
  4. Cells that perform similar functions are grouped together to form tissues.
  5. An experiment is a controlled setting/test that investigates (proves or disproves) a scientist's hypotheses.
  6. One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
  7. Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.The amount of coke is the independent variable.
  8. Homeostasis is defined as an organism's ability to regulate its internal environment in response to fluctuations in the external environment.
  9. A community is a group of populations (different species) inhabiting one place at one time.
  10. In the scientific method, a good theory generates further hypotheses that can be tested.
  11. Multicellular organisms are composed of more than one cells.
  12. Biology is the scientific study of life. <em>Bio</em> means life and <em>logos</em> means study, thought or reasoning.
  13. An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.
  14. According to the second postulate of the Cell Theory, the cell is the basic structural and functional unit of life.
  15. Eukaryotes constitute one entire domain of the tree of life. They are distributed in 4 major kingdoms of life.
  16. A dependent variable, also known as response variable, defines the treatment/variable that changes in response to the independent variable.
  17. Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
  18. Homeostasis is defined as an organism's ability to respond and regulate its internal environment in response to fluctuations in the external environment.
  19. The experimental and control groups differ in the independent variable as only the experimental group receives the variable or treatment.
  20. Quantitative data is quantifiable, numerical data in which the effects of the independent variable on the response variable can be compared through mathematical and statistical tools.
  21. A good theory is universal,broad in scope and substantiated by a large body of evidence.
  22. A good theory is universal,broad in scope and substantiated by a large body of evidence.
  23. A jungle is a group of a single species of dense vegetation.
  24. An organism is an individual living being composed of cells, tissues, organs and organ systems.
  25. Fungi, being saprophytic in nature are the principal decomposers on Earth.
  26. Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.
  27. A population is a single species of organisms inhabiting a single area at a time.
  28. Organisms of the domain Archaea are known to be extremophiles i.e. organisms that can survive and thrive in harsh environmental conditions.
  29. A hypothesis is a potential explanation for observable phenomena.
  30. The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
  31. The three domains of life: Eukarya (Eukaryotes), Archaea and Bacteria (Prokaryotes).
  32. A cell is made up of different organelles performing diverse functions for the cell.
  33. The properties of life include: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
  34. Each level of the hierarchy of life entails the addition of new properties, complexity and more complex functions.
  35. One of the major properties of life is to harvest and convert energy to drive basic cellular processes.
  36. A well tested and substantiated hypothesis leads to the development of a theory that can further be subjected to experimentation.
  37. An ecosystem is an ecological structure in which both biotic and abiotic factors interact with each other.

Biological classification is important because it allows scientists to study organisms in a ___ way​
puteri [66]

Answer:

Systematic.

Explanation:

Biological classification is important because it allows scientists to study organisms in a systematic way​.

In Science, this biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.

Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.

Hence, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
