Biomolecules
Observations & Inferences
100
An organism's ability to maintain a stable internal environment despite changing external conditions.
Homeostasis
100
What are are the basic structural and functional units of all living things.
Cells
100
Known as the powerhouse of the cell, this organelle converts glucose into ATP through cellular respiration.
What is the mitochondrion (or mitochondria)?
100
Monosaccharides such as glucose serve as the monomer building blocks for this class of biomolecules, used for quick energy and structural support
Carbohydrates
100
Gathering direct information about an object or process using the five senses or scientific instruments is known as this.
What is an observation?
200
The sum of all chemical reactions that take place within an organism to break down or build up materials.
Metabolism
200
the third tenet of Cell Theory states that all new cells originate from these.
Other Cells (Pre-existing cells)
200
ound in plant, fungal, and bacterial cells, this rigid structure sits outside the cell membrane to offer support and protection.
Cell Wall
200
Amino acids link together via peptide bonds during translation to construct these functional macromolecules.
What are proteins?
Polypeptides also acceptable answer
200
This term describes a logical conclusion or explanation derived from gathered evidence and prior knowledge is called this.
Inference
300
A Venus flytrap snapping shut when a fly touches its sensory hairs is an example of a organism responding to this environmental trigger.
Response to Stimulus
300
Animal cells have this classification because they contain membrane bound compartments known as organelles
Eukaryotic
300
This membrane bound organelle acts as the "control center" in Eukaryotic cells, and contains and maintains all of its DNA.
Nucleus
300
Nucleotides are the monomers that form DNA and RNA, which belong to this macromolecule category responsible for genetic storage.
Nucleic Acids
300
Noting that a solution turned dark purple or produced a sulfur-like smell is an example of this non-numerical type of observation.
What is a qualitative observation
400
This characteristic of life can be exemplified by the process by which unspecialized stem cells turn on specific genes to develop distinct structures and functions during an organism's life cycle.
Order / Levels of Organization (Cells)
400
Bacterial cells have this classification because they lack membrane bound organelles. For example their DNA is free floating within the cytoplasm.
Prokaryotic
400
This membrane-bound organelle contains hydrolytic digestive enzymes to break down cellular waste, damaged organelles, and foreign invaders.
Lysosome
400
Lipids are hydrophobic and nonpolar because their fatty acid chains consist primarily of nonpolar covalent bonds between these two elements.
Carbon and Hydrogen
400
Recording that a bacterial colony grew by 14.2 millimeters in diameter over 24 hours is an example of this data type.
What is a quantitative observation?
500
Viruses possess genetic material and evolve, yet are often classified as non-living because they lack metabolic machinery and cannot reproduce without this fundamental unit of life
Cell
500
The Endosymbiotic Theory explains how eukaryotic cells evolved, supported by the fact that mitochondria and chloroplasts contain their own ribosomes and a circular molecule of this.
DNA
500
In plant cells, this large fluid-filled storage organelle regulates osmotic (flow of water) balance and provides structural rigidity by exerting turgor pressure against the cell wall in plants cells.
Central Vacuole
500
This structure below represents what biological macromolecules ( biomolecule)
Polysaccharide (Carbohydrate)
500
A student sees bubbles forming when yeast mixes with sugar water (Observation) and states that carbon dioxide gas is being produced by cellular respiration. This second statement represents this scientific process.
What is an inference?
