What is the primordial soup theory regarding the origin of life?
Life was created by spontaneous generation from inorganic materials.
Life began in a sterile environment with no organic compounds.
The primordial soup theory posits that life began in a nutrient-rich environment filled with organic compounds, driven by energy sources.
Life originated from extraterrestrial sources like comets.
What are the main characteristics that define living organisms?

Explain the process of asexual reproduction in plants.
Seed dispersal mechanisms

What are the advantages of sexual reproduction in animals?
Genetic diversity, adaptability, and evolutionary advantages.
Increased risk of disease transmission

Limited genetic variation
Describe the role of pollinators in plant reproduction.
Pollinators are crucial for transferring pollen, enabling fertilization and seed production in plants.
Pollinators are primarily responsible for photosynthesis.
Pollinators only help in plant growth.
Pollinators do not affect seed production.
What is the difference between external and internal fertilization?
External fertilization is exclusive to mammals, while internal fertilization is for fish.
Both external and internal fertilization happen inside the body.
External fertilization occurs inside the body, while internal fertilization happens outside.
External fertilization happens outside the body, while internal fertilization occurs inside the body.
How do flowering plants reproduce?
Flowering plants reproduce by seed dispersal only.
Flowering plants reproduce through vegetative propagation.
Flowering plants reproduce asexually through cloning.
Flowering plants reproduce sexually through pollination and fertilization.
Which is an advantage of internal fertilization?
Offspring is much safer since it is protected outside the mother's womb
Faster rate of development
Multiple offspring is produced
Parental care is ensured and offspring is protected inside the mother's womb
What is the role of DNA in heredity?
DNA is the molecule that carries genetic information and is responsible for heredity.
DNA is responsible for energy production in cells.
DNA has no role in the inheritance of traits.
DNA is only found in the nucleus of a cell.
Which of the following describes homeostasis?
keeps variables exactly at the set point

materials as it carries out its life processes is called ...
absorption
metabolism
digestion
consumption
Maintaining a stable internal
environment is called
homeostasis
equilibrium
balance
