Biomolecules, Cells & Viruses
This type of biomolecule is the body’s main source of quick energy.
What are carbohydrates?
This process allows molecules to move from an area of high concentration to low concentration without using energy.
What is passive transport?
This type of mutation involves the replacement of one nucleotide with another in the DNA sequence.
What is a point mutation?
This concept, proposed by Charles Darwin, explains that organisms with traits better suited to their environment are more likely to survive and reproduce.
What is natural selection?
This system is responsible for transporting oxygen and nutrients throughout the body.
What is the circulatory system?
This organelle acts as the control center of the cell, housing the DNA.
What is the nucleus?
This structure in the cell controls the movement of substances in and out, maintaining homeostasis.
What is the cell membrane?
This mutation results in the insertion or deletion of one or more nucleotides, potentially altering the entire protein sequence.
What is a frameshift mutation?
This evolutionary mechanism occurs when a population downsizes due to natural disasters, or disease.
What is genetic drift?
In this type of relationship, one organism benefits while the other is harmed. An example is a tick feeding on a dog.
What is parasitism?
Unlike living cells, viruses lack this structure necessary for energy production.
What is a mitochondria?
During this phase of mitosis, the chromosomes line up in the center of the cell before being separated.
What is metaphase?
This percent shows the dominant phenotype when crossing two heterozygous genotypes.
What is 75%?
In plants, this structure allows for the exchange of gases, such as oxygen and carbon dioxide, with the environment.
What is stomata?
These two systems work together to provide movement.
What is skeletal and muscular systems?
These biomolecules are made up of amino acids and are responsible for building and repairing tissues.
What are proteins?
A solution that makes a cell swell.
What is a hypotonic solution?
This inheritance pattern occurs when one allele is not completely dominant over the other, leading to a blended phenotype, as seen in flower color in some plants.
What is incomplete dominance?
These three parts make up the pistil.
What is ovary, stigma, and style?
This is the term for the visual representation that shows this decreasing energy as you move up levels.
What is an energy pyramid?
This part of the cell theory is violated by viruses, making them non-living.
What is “all cells come from pre-existing cells”?
In meiosis, this process results in the exchange of genetic material between homologous chromosomes, increasing genetic diversity.
What is crossing over?
This type of inheritance pattern occurs when both alleles contribute equally to the phenotype, as seen in AB blood type.
What is codominance?
This tissue only flows upwards in plants.
What is Xylem?
These relationships make up our environment. Every interaction is categorized into one of these. (There are 5).
What is predation, parasitism, commensalism, competition, and mutualism?
