Energy
All energy used by living things on Earth can be traced back to this ultimate source.
What is Solar Energy?
When certain traits help an organism survive and reproduce, this evolutionary process is at work.
What is Natural Selection?
This molecule carries genetic instructions and is shaped like a double helix.
What is DNA?
This scale goes from 0-14 and can is known to be a measure of how acidic or alkaline something is
What is the pH scale?
This process moves molecules from an area of high concentration to an area of low concentration without using energy.
What is diffusion?
This process converts sunlight, carbon dioxide, and water into glucose and oxygen.
What is Photosynthesis?
What is survive?
Different forms of the same gene are called this.
What is Allele?
This term describes an organism’s ability to maintain a stable internal environment.
What is Homeostasis?
This term describes the harmful addition of substances like carbon dioxide into the environment, leading to problems such as ocean acidification.
What is Pollution?
Known as the “powerhouse of the cell,” this organelle turns food into usable energy.
What is the Mitchondria?
This process occurs when humans breed plants or animals for specific traits, such as faster horses or sweeter fruit.
What is artificial selection?
These threadlike structures, made of DNA, contain many genes.
What is a chromosome?
This environmental process threatens coral reefs by lowering pH and dissolving calcium carbonate.
What is ocean Acidification?
Through artificial selection, humans bred these animals into hundreds of dog breeds with different sizes, coats, and temperaments.
What are Wolves?
This organelle captures sunlight to make food for the plant.
What are chloroplast?
artificial selection, genetic drift, and natural selection are all examples of factors that cause ______ ________ to change over time
What is Allele Frequencies?
This term describes the combination of alleles an organism has for a specific trait.
What is a genotype?
As CO2 is dissolved in the ocean is having this effect on the oceans overall pH
What is decreasing?
This hard, round outer shell protects a sea urchin’s body and is made mostly of calcium carbonate.
What is the test?
This energy-carrying molecule is produced during cellular respiration.
What is ATP?
This term describes random changes in allele frequencies over time.
What is Genetic Drift?
The physical appearance of a trait, such as eye color or height, is known as this.
What is a phenotype?
This ion is found in high concentrations in acidic solutions and contribute to lower pH levels
H+ Ions
What is the relationship between CO2 and pH?
