Life Science and Cosmic Structures Quiz

Study Notes

Life Science

Life science is the study of living organisms and their interactions with each other and their environment.
It encompasses a broad range of disciplines, including biology, ecology, genetics, and physiology.
Key concepts in life science include evolution, adaptation, and biodiversity.
Life science explores the structure, function, growth, origin, evolution, and distribution of living things.

Milky Way Galaxy

The Milky Way is a barred spiral galaxy containing our Solar System.
It consists of billions of stars, gas, dust, and dark matter.
The galaxy's structure includes a central bulge, spiral arms, and a halo.
The Sun is located in one of the spiral arms, roughly halfway between the galactic center and the edge.
The Milky Way is estimated to be about 13.5 billion years old.

Solar System

The Solar System is a gravitationally bound system comprising the Sun and the objects that orbit it.
The major components are the Sun, planets, moons, asteroids, comets, and dwarf planets.
The Sun is the central star and accounts for the vast majority of the system's mass.
Planets orbit the Sun in elliptical paths.
The inner solar system includes rocky planets (Mercury, Venus, Earth, Mars), and the outer solar system includes gas giants (Jupiter, Saturn, Uranus, Neptune).
Dwarf planets include Pluto and other similar celestial bodies.

Microorganism's

Microorganisms are microscopic living organisms, too small to be seen with the naked eye.
They include bacteria, archaea, fungi, protists, and certain types of algae.
Microorganisms play crucial roles in various ecosystems, including decomposition, nutrient cycling, and food webs.
They can be beneficial or harmful.
Some microorganisms cause disease, while others are essential for human and animal health (e.g., aiding digestion).
Microorganisms are fundamental to life on Earth and are present in nearly every environment.
Microbial diversity is vast and their actions impact climate change and other large scale processes.
Microorganisms like bacteria have crucial roles in the decomposition of organic matter, recycling vital nutrients like nitrogen and phosphorus, and forming the foundation of the food web in many environments.
Viruses, though not considered living organisms in the same way, also fall into this category as they are microscopic and impact living systems.
