What is the word equation for photosynthesis? - ANSWER-Carbon dioxide +
water → glucose + oxygen.
What is a balanced diet composed of? - ANSWER-Carbohydrates, proteins, lipids,
vitamins, minerals, water, and dietary fiber.
What is the role of bile in digestion? - ANSWER-Bile neutralizes stomach acid and
emulsifies fats.
What is the function of the human alimentary canal? - ANSWER-It processes food,
absorbing nutrients and eliminating waste.
,What is respiration? - ANSWER-The process of producing ATP by breaking down
glucose in the presence or absence of oxygen.
What is aerobic respiration? - ANSWER-Respiration that requires oxygen to
produce ATP.
What is anaerobic respiration? - ANSWER-Respiration that occurs without
oxygen, producing less ATP.
What is gas exchange? - ANSWER-The process of exchanging oxygen and carbon
dioxide between organisms and their environment.
What is the role of stomata in plants? - ANSWER-Stomata allow gas exchange for
photosynthesis and respiration.
What is the structure of the heart? - ANSWER-The heart consists of four
chambers: two atria and two ventricles.
What is the function of red blood cells? - ANSWER-Red blood cells transport
oxygen throughout the body.
What is excretion? - ANSWER-The process of removing waste products from the
body.
What are the main organs of excretion in humans? - ANSWER-Lungs, kidneys,
and skin.
What is homeostasis? - ANSWER-The maintenance of a stable internal
environment in an organism.
, What is the role of neurotransmitters? - ANSWER-Neurotransmitters transmit
signals across synapses in the nervous system.
What is a reflex arc? - ANSWER-A neural pathway that controls a reflex action.
How do plants respond to stimuli? - ANSWER-Plants respond through growth
movements, such as phototropism and gravitropism.
What is the function of auxin in plants? - ANSWER-Auxin regulates plant growth
and responses to light.
What are the two main types of reproduction? - ANSWER-Sexual and asexual
reproduction.
What is fertilization? - ANSWER-The fusion of a male and female gamete to
produce a zygote.
What is the role of the pollen tube in flowering plants? - ANSWER-It leads to
fertilization, resulting in seed and fruit formation.
What are the adaptations of insect-pollinated flowers? - ANSWER-They have
bright colors, scents, and nectar to attract insects.
What are the adaptations of wind-pollinated flowers? - ANSWER-They have
small, dull flowers and produce large quantities of lightweight pollen.
