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.
  38. Independent or test variable does not depend on any other factors. It is itself changed to determine its effect on the response variable.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages​
elena-s [515]

Answer:

75years

Explanation:

Let the Father's age be represented by 2x

Let the Son's age be represented by x

Five years ago;

Man's age will be = 2x - 5

Son's age will be = x - 5

If the ratio of their ages five years ago was 9:4, then;

2x - 5/x-5 = 9/4

4(2x - 5) = 9(x - 5)

8x - 20 = 9x - 45

- Collect like terms

-20 + 45 = 9x - 8x

25 = x

Hence, the son's age = 25 years

If x = 25, the father's age (2x) will be 2 × 25 = 50years

The sum of their ages will be = 25years + 50years = 75years
