Species changing over time
The process of heritable change in populations of organisms over multiple generations.
What is evolution?
Version of a trait
What is an allele?
Increase hydrogen concentration of solution because they disassociate and yield hydrogen
What is an acid?
Substance that dissolves a solute
What is a solvent?
Bacteria, Archaea, and Eukarya
What are the 3 domains of life?
A population can change if an individual with particular traits have an advantage in adapting to a particular environment.
What is natural selection?
Having identical alleles
What is homozygous?
A process in which heat is absorbed
What is an endothermic process?
"water loving"
What is hydrophilic?
Cells, tissues, organs, organ systems, and organism
What is the organization of life?
The ability to survive to reproductive age, find a mate, and produce offspring
What is fitness?
Physical characteristics
Protons + neutrons
What is atomic mass?
High concentration to low concentration with no energy
ex: moving downhill (doesn't require energy)
What is diffusion?
- Backbone
- Protected by vertebrae + skull
- Larger size
- Active
- Highly cephalized
- Well-developed sense organs
What is a vertebrate?
A trait that increases the fitness of an individual in a particular environment.
What is adaption?
mRNA is translated to synthesis of protein
What is translation?
Energy thats in bond of molecules
What is chemical energy?
low concentration to high concentration with energy
ex: going uphill (req. energy)
What is active transport?
Animals whose embryos consist of three types of tissues
What is a tripoblast?
Natural selection causes population to change based on environment.
What is speciation?
- deoxyribonucleic acid
- double stranded
- purpose: storage and transmission of genetic information
- A-T(Adenine-Thymine), G-C(Guanine-Cytosine)
What is DNA?
- Electron pairs are not shared equally
- Soluble
- Charged
- Hydrophilic
What are the characteristics of polar molecules?
A solution which has a higher concentration of water
What is a hypotonic solution?
- Sexual, usually in AQUATIC species,
- females lay EGGS onto a substrate in open WATER.
- Males shed SPERM, which SWIM on or near the eggs.
What is external fertilization?
