Living Environment Regents Exam |101 Questions and Answers
(101 Way to master the Living Environment Regents Exam)
Define organism - -a living thing
-What is the life function that "maintains internal stability" in an organism? - -Homestasis
-What life function includes all of the chemical reactions that occur in an organism? - -
Metabolism
-Name the levels of organization for living things starting with organism and ending with
cells. - -organism, organ systems, organs, tissues, cells
-Name the four main organic molecules that make up living things. - -carbohydrates,
proteins, fats, DNA
-Name at least five organ systems in humans. - -respiratory system, digestive system.
circulatory system, excretory system, nervous system, endocrine system, immune system,
integumentary system, muscular system, skeletal system, reproductive system.
-Which organic molecule includes starches and simple sugars like glucose? - -
carbohydrate
-Name three inorganic molecules that are important to living things. - -water, oxygen,
carbon dioxide
-What are the parts of a cell that perform life functions called? - -organelles
-Which cell organelle controls what molecules enter and leave the cell - -cell membrane
-Which cell organelle contains the genetic material of the cell? - -nucleus
-Which cell organelle contains the material that codes for proteins? - -nucleus
-Which cell organelle is the site where proteins are assembled/synthesized? - -Ribosome
-Which organelle in a cell accomplishes waste disposal? - -Cell membrane (waste diffuses
out of it)
-What molecules make up a cell membrane? - -Lipids/phospholipids and proteins
-What part of the cell membrane is able to recognize chemical signals? - -Receptor
proteins
, -When starch is digested, what smaller molecules is it digested unto? - -Simple sugars like
glucose
-When a protein is digested, what smaller molecules is it digested? - -Amino Acids
-What molecules have specific shapes that are very important to their functions? - -
Enzymes, Receptors molecules, antibodies, chemical signals
-In which cell organelles would respiratory enzymes be found? - -Mitochondria
-In which cell organelle would light be used to convert inorganic molecules into organic
molecules? - -Chloroplast
-During photosynthesis, what gas do plants absorb (take in)? - -Carbon Dioxide
-During photosynthesis, what gas do plants release? - -Oxygen
-What organic molecule is made by plants during photosynthesis? - -Carbohydrates (such
as glucose)
-What is the purpose of photosynthesis for the plant? - -To make organic molecules
(nutrients) for the plant
-What is the purpose of respiration in plants, animals, and other organisms? - -To extract
energy from nutrients/ to make ATP for energy for life functions (glucose + oxygen -
BOOM! Give us energy!)
-What gas is taken in during respiration? - -Oxygen
-What gas is released during respiration? - -Carbon dioxide
-What makes up the genetic code in DNA? - -The sequences of bases (A, C,G,T)
-What does DNA code for? - -The order of amino acids needed to make protein
-What is the cause of acid rain? - -When fossil fuels are burned by cars or factories, they
release nitrogen and sulfur compounds into the air, which become nitric and sulfuric acid.
-What effects does acid rain have on living things? - -Acid rain lowers the ph in water,
often killing the eggs and young of the fish and amphibians. It can also damage the leaves of
plants.
-What if the cause of global warming? - -Excess dioxide builds up in the atmosphere and
traps heat (the "green house" effect)
