What is the smallest unit of life?
Cell
What is the primary purpose of respiration in living organisms?
A) Production of glucose
B) Release of energy
C) Synthesis of proteins
D) Regulation of body temperature
B) Release of energy
What is the main purpose of nutrition in living organisms?
A) Growth and development
B) Regulation of body temperature
C) Oxygen production
D) Protection against diseases
A) Growth and development
What is the purpose of reproduction in living organisms?
Reproduction ensures the continuation of a species
What is the level of organization above organ systems in living organisms?
Organism
Where does the process of respiration primarily take place in a cell?
A) Nucleus
B) Mitochondria
C) Endoplasmic reticulum
D) Golgi apparatus
B) Mitochondria
Where does the process of digestion primarily begin in the human body?
MOUTH
Explain the difference between sexual and asexual reproduction.
Sexual reproduction involves the fusion of gametes from two parents to produce offspring with genetic variation. Asexual reproduction, on the other hand, involves only one parent and produces offspring that are genetically identical to the parent.
Name the two types of organisms based on their cells.
Eukaryotes and Prokaryotes
Organization for 400:
How is oxygen transported from the lungs to the cells in the human body?
A) Through the bloodstream
B) Through the lymphatic system
C) Through the nervous system
D) Through the respiratory system
A) Through the bloodstream
Which nutrient is primarily responsible for providing energy to living organisms?
A) Proteins
B) Lipids
C) Carbohydrates
D) Vitamins
C) Carbohydrates
Give an example of an organism that reproduces asexually.
BACTERIA
What is the role of tissue in multicellular organisms?
Group of cells working together towards a specific function
Why do living organisms need to exhale carbon dioxide?
A) To regulate pH levels in the blood
B) To absorb more oxygen
C) To release excess energy
D) To eliminate waste products
D) To eliminate waste products
Why is it important for living organisms to have a balanced diet?
A) To maintain a healthy weight
B) To prevent nutrient deficiencies
C) To improve vision
D) To increase energy levels
B) To prevent nutrient deficiencies
How does reproduction contribute to genetic diversity?
Reproduction contributes to genetic diversity through the combination of genetic material from two parents during sexual reproduction. This genetic recombination results in offspring with unique genetic traits, increasing variability within a population and enhancing its ability to adapt to changing environments.
What is the function of organelles within a cell?
Carrying out specific functions within the cell
What is the key difference between aerobic and anaerobic respiration?
Aerobic requires oxygen, anaerobic does not
Which of the following best describes autotrophic nutrition?
A) Obtaining nutrients from other organisms
B) Producing own food using sunlight
C) Consuming only animal products
D) Absorbing nutrients from the soil
B) Producing own food using sunlight
