Unit 1
What is the difference between observation and inference?
An observation is a conclusion based on your five senses, whereas an inference is a conclusion based on your observations.
What is the cell theory?
According to the cell theory, cells make up every biological entity; they are the basic building block of life, and all life originates from earlier forms of life.
What is DNA, Chromosomes, and Genes?
Your unique characteristics are shaped by your DNA, genes, and chromosomes. DNA is carried in cells by chromosomes. The creation and upkeep of your human anatomy are accomplished by DNA. Your unique physical attributes are a result of portions of your DNA called genes.
What is evolution?
Evolution is the process by which the characteristics of a species change over several generations and is based on natural selection.
What is the difference between learned and innate behavior?
Innate behavior is inherited by an animal. Instincts are examples of an animal's innate behavior. Learned behavior is acquired through observation of other animals and life experiences.
What is the difference between theory and law?
Laws explain what will happen in a given situation using a mathematical equation, whereas theories explain how the phenomenon occurs.
What is cell structure and function?
An organism's structural support is provided by its cells. The nucleus contains all the genetic material needed for reproduction. Cell organelles are suspended in the cytoplasm and constitute a structural component of the cell. The organelle in charge of providing the cell's needs for energy is the mitochondria.
What is the difference between probability and predictions?
Probabilities are based on mathematical formulas and sets of historical data. Predictions have a strict right or wrong outcome. There is a spectrum of probabilities, ranging from very unlikely to very likely. Predictive success is not always certain, not even by subject matter experts with in-depth knowledge.
What is natural selection?
Natural selection is the process by which living organism populations adapt and change. Individuals in a population are naturally variable, which means they differ in some ways. This variation indicates that some people have traits that are better suited to their environment than others.
What is the physical adaptation in animals?
Adaptation is a physical or behavioral feature of an animal that allows it to survive in its environment. In other words, an adaptation is something on their body or something they do with their bodies that helps them find food, water, mates, and shelter.
What is hypothesis?
It is a proposition for an explanation of an occurrence that has been observed or a testable claim concerning the relationship between two or more variables.
What are the two main types of cells?
Prokaryotic cells and eukaryotic cells are the two primary categories of cells. Archaea and bacteria are prokaryotic cells. Prokaryotes, which are made up of prokaryotic cells, are invariably single-celled organisms (unicellular). Prokaryotic cells are devoid of nuclei.
What is the purpose of punnet squares?
Punnett Squares are a useful tool for predicting the changes and probabilities that can result from cross-breeding. This includes foreseeing interspecies hybridization between plants, animals, and even people.
What is artificial selection?
Artificial selection is the process by which humans select individual organisms with specific phenotypic trait values for breeding. If the selected trait has additive genetic variance, it will respond to selection, i.e. the trait will evolve.
Homeostasis is the process by which animals maintain a constant internal balance in their bodies. It enables animals to function in the constantly changing external conditions that surround their bodies.
