Genetics and Heredity
What molecule contains the instructions for making proteins?
DNA
What process do plants use to make their own food?
Photosynthesis.
What is evolution?
Changes in traits in a population over time.
Name one of the characteristics of living things.
Made of cells, has DNA, can reproduce, can respond to their environment, can maintain homeostasis, can grow and develop, and can use energy.
What animal has three hearts?
The octopus
What is a gene?
A section of DNA that codes for a specific trait (protein).
Name one of the three inputs for photosynthesis?
CO2, Water, and Sunlight
What is an adaptation?
An advantageous trait that helps an organism survive and reproduce.
What is the smallest unit of life.
A cell!
What is the largest animal on Earth?
The blue whale.
What is the name of the first step of protein synthesis?
Transcription
Name BOTH of the outputs of photosynthesis?
Glucose and Oxygen
What does VISTA stand for?
Variation, inheritance, survival, reproduction, adaptation, and time.
Why do scientists use multiple characteristics to decide if something is living?
One characteristic alone is not sufficient evidence.
What animals can regrow lost body parts?
Sea star
If a mutation changes DNA, what could be the effect?
Changes the trait. Could be harmful, helpful, or neutral.
Why do flowers have bright colors and nectar?
To attract pollinators.
Why is variation important in a population?
It allows some individuals to survive changes in the environment.
A dog running away from a loud noise is an example of what characteristic of life?
Response to the environment.
True or False: Plants can communicate with each other.
True.
Why are siblings similar but not identical?
How does pollen help plants reproduce?
Carries genetic material from one flower to another.
True or False: A individual organism evolves during its lifetime.
False! Populations changes over time.
Are viruses living or nonliving?
Viruses are technically nonliving. While they do have some of the characteristics of life, they do not reproduce on their own, respond to the environment, maintain homeostasis, use energy, or grow and develop.
What animal is known as the unicorn of the sea?
The Narwhal!
