Creating a genetically identical copy of an organism.

A famous cloned sheep.

A genetically identical copy of another organism.

The original organism used to create a clone.

The scientist who cloned Dolly.

The basic unit of life.

The control center of a cell, containing genetic material.

A part of a sheep's udder, specifically a cell, from which a clone was developed.

Bad ozone is found in the troposphere, the lowest layer of Earth's atmosphere.

Good ozone is located in the stratosphere, a layer higher up in the atmosphere than the troposphere.

Good ozone in the stratosphere shields Earth from harmful ultraviolet radiation.

Bad ozone in the troposphere can harm human lungs and plants.

A rock in space that enters Earth's atmosphere.

Meteoroids heat up and glow as they fall through Earth's atmosphere.

Entering the atmosphere causes meteoroids to heat up and glow.

Rocks in space that enter the Earth's atmosphere.

The Earth spinning on its axis, causing day and night.

The Earth's axis is tilted at 23 degrees, causing seasons.

The day with the most daylight hours in the Southern Hemisphere, expected around December 22nd of a year.

The day with the fewest daylight hours in the Southern Hemisphere, expected around June 20th of the year.

Duration of daylight in Melbourne, Australia, on June 20th (9 hours 32 minutes).

Oils and waxes mix well together, while oils and water do not.

Lipstick is harder and lip gloss is softer and creamier, due to different ingredient combinations.

Adding a lot of water to a heated lipstick mixture will likely cause problems because water and waxes (in ingredients) do not mix.

As a meteoroid approaches Earth's atmosphere, it speeds up due to the Earth's gravitational pull.

When a meteoroid impacts Earth, it creates a hole called a crater.

Bread dough rises because carbon dioxide gas is produced during fermentation.

Fermentation converts starches and sugars in flour into carbon dioxide and alcohol.

The loss of weight in bread dough is due to the escape of carbon dioxide and other gases during fermentation.

To determine if yeast causes dough loss, compare experiments considering yeast as the factor in one compared to a similar one without yeast

When heated, gases and vapors within dough expand due to increased molecular movement.

A leavening agent, like yeast, causes dough to rise by producing gas, like carbon dioxide.

A method of raising fish that minimizes environmental impact and ensures the long-term health of fish populations.

Sugars in drips provide essential nutrients to patients unable to eat or drink after surgery.

Two main challenges are feeding the farmed fish and maintaining water quality.

Recovered individuals develop antibodies that prevent reinfection with the same bacteria by killing it or preventing multiplication.

Fish farms need to produce enough food for the fish they raise, ideally using sustainable methods.

Waste from farmed fish can harm their environment, so sustainable farms need to remove waste and excess nutrients.

Major surgery is performed in specially equipped operating rooms.

Introducing a mild form of a virus to prevent severe infection later.

Microscopic organisms that use sunlight and nutrients to grow. They are used in sustainable fish farms as a food source and for cleaning water.

Invertebrates that grow quickly on a diet of microalgae and are a natural food for fish.

Mary Montagu and later Edward Jenner explored and used inoculation techniques to prevent diseases.

A system of tanks where filtered seawater flows through and organisms are carefully placed to promote natural food chains.

A drip containing water, sugars, and mineral salts, possibly with antibiotics or tranquillisers, provided for immediate post-surgery nutritional and supportive care.

The body creates antibodies to prevent reinfection by the same type of bacteria.

A type of fish that is targeted for sustainable farming. They prefer to eat ragworms.

Molecules move faster when an object heats up.
