Matter
This term describes anything that has mass and takes up space.
What is Matter?
What is an atom?
This is the basic unit of life and the smallest structure capable of performing all life processes.
What is a cell?
This diagram is used to predict the possible genotypes of offspring.
What is a Punnett Square?
This is the layer of the atmosphere closest to Earth's surface, where we live and breathe.
What is the Troposphere.
This process occurs when a substance changes directly from a solid to a gas without becoming a liquid.
What is sublimation?
These negatively charged particles orbit the nucleus of an atom.
What are electrons?
This jelly-like substance fills the cell and holds its organelles.
What is cytoplasm?
In genetics, this term refers to the physical expression of a gene.
What is phenotype?
This layer of the atmosphere contains the ozone layer, which protects Earth from harmful ultraviolet radiation.
What is the stratosphere?
This type of mixture has particles that are large enough to be seen and can be separated by physical means.
What is a Heterogeneous mixture?
The number of these particles in the nucleus determines the atomic number of an element.
What are protons?
This organelle is often called the "powerhouse" of the cell because it produces energy.
What is the mitochondrion?
This type of allele is expressed even when only one copy is present.
What is dominant?
This layer of the atmosphere is known for its extremely low temperatures and is where meteors typically burn up.
What is the Mesosphere?
In this state of matter, particles have a definite volume but no fixed shape, and they flow easily.
What is a liquid?
This is the neutrally charged particle in the nucleus.
What is a Nuetron
This process, occurring in the chloroplasts of plant cells, uses sunlight, water, and carbon dioxide to produce glucose and oxygen.
What is photosynthesis?
When crossing two heterozygous individuals for a single trait, this ration of phenotypes is expected in the offspring.
What is 3:1 (Three to one)?
This upper layer of the atmosphere contains the aurora borealis and aurora australis.
What is the Thermosphere?
In this state of matter, particles have no definite shape or volume, can expand indefinitely, and fill their entire container.
What is a gas?
Atoms of the same element with different numbers of neutrons are called this.
What are isotopes?
Found in plant cells but not animal cells, this rigid structure is primarily composed of cellulose and provides support and protection.
What is the cell wall
In pea plants, the allele for tall stems (T) is dominant over the allele for short stems (t). If a heterozygous plants is crossed with a short plant, what percentage of the offspring are expected to be short?
What is 50%?
The two most abundant gases in Earth's atmosphere are nitrogen and this gas, which makes up approximately 21% of the atmosphere.
What is oxygen?
