Process Of Science & Properties of Life
What is the process called that allows scientists to run an experiment?
What is the scientific method.
What is the strongest bond?
What is a covalent bond
What are the four biological molecules?
What are carbohydrates, lipids, proteins, and nucleic acids.
What helps us understand the cell and how it came to be?
What is cell theory.
This organelle contains water, nutrients, proteins, and other organelles in the cell.
What is the cytoplasm.
What is the difference between an independent and dependent variable?
What is...
Independent variable- the variable being manipulated in an experiment
Dependent variable- the variable that is measured as a response during the experiment
What is an ionic bond?
What is a bond between a negative and a positive atom where a atom gives an electron to another one.
Polymers are multiple chains of identical building blocks. How are they built?
What is dehydration synthesis?
Animals and plants are an exam of this type of cell.
What is a eukaryotic cell.
What are the three types of cytoskeleton fibers?
What are microfilaments, intermediate filaments, and microtubules.
What are the seven properties of life?
What is order, reproduction, response to environment, growth and development, regulation, energy processing, and evolutionary adaptation.
What is a hydrogen bond?
What is a bond between a partially positive hydrogen on one molecule and a partially negative atom on another molecule.
What are the components of a phospholipid?
What is a hydrophilic phosphate head and hydrophobic fatty acid tails.
What is a prokaryotic cell.
What is synthesis, distribution, storage, and export of molecules.
What is homeostasis?
What is the maintenance of internal conditions within a narrow range.
Why can table salt dissolve in water but olive oil cannot?
What is olive oil being hydrophobic and table salt being an ionic compound.
This polysaccharide is found in plant cells and is indigestible in humans.
What is cellulose.
What is the purpose of having membrane-bound organelles?
What is the specialization of processes within a cell.
What organelles are found in plant cells but not in animal cells?
What are chloroplasts, the central vacuole, and the cell wall.
A good experiment takes what three things into consideration?
What are control groups, sample size, and randomization?
Why is water polar?
What is...
oxygen is more electronegative than hydrogen so there is an unequal sharing of electrons leading oxygen to be partially negative while the hydrogen atoms are partially positive.
What is...
Linear structure: a linear shaped protein where covalent and peptide bonds hold the protein together w/ the backbone interacting
Secondary structure: alpha helix or beta sheet with hydrogen bonds and the backbone interacting
Tertiary structure: 3-D shape with ionic bonds and hydrophobic interactions with the R-groups interacting
Quaternary: multiple tertiary structures interacting
What cells are living?
What are prokaryotic and eukaryotic cells.
Mitochondria and Chloroplasts are closely related. Each organelle has its own DNA, both have double membranes, and are approximately the same size as prokaryotic cells. What is this called?
What is the endosymbiont theory.
