,What is matter? - correct ans:Anything that takes up space,by having a
volume, and has mass
Match the following protein structures with the correct description:
Primary:
Secondary:
Tertiary:
Quarternary: - correct ans:Primary: order in which amino acids are arranged
in a polypeptide chain
Secondary:includes repeating patterns
Tertiary: 3- dimensional shape
Quarternary: when 2 or more chains react
selective permeability - correct ans:Ability or certain substances to move
through the cell membrane while others can't
What type of leopard is made up of four fused carbon runs with attached
functional groups that often contain an alcohol? - correct ans:Steroids
What type of ion carries a negative charge? - correct ans:anion
Which organelle of the cell contains the genomic content of the cell and
serves as a control center of the cell? - correct ans:Nucleus
True or false. Passive transport is vital for moving essential nutrients into the
cell. Should passive transport stop the cell would cease to function. - correct
ans:False. active transport is vital for moving essential nutrients into the cell.
, What are the four bio macro molecules? - correct ans:Carbohydrates, lipids,
proteins, and nucleic acids
What type of cell junctions are mechanical structures that wrap around the
cell to prevent extra cellular fluid from leaking? - correct ans:Tight junctions
What chemical molecules carry genetic information within the cell? - correct
ans:nucleic acids
Which of the following statements is true concerning eukaryotic cells? -
correct ans:Eukaryotic cells possess a nuclear membrane.
True or false trace elements are required only in small quantities? - correct
ans:True.
As part of the cytoskeleton, what role do microtubules serve? - correct
ans:Microtubules influence cell shape, form spindles for chromosome
separation and serve as roads for organelles to travel
What are the two main components of phospholipids? - correct ans:(1) a
polar head group joined to (2) a non-polar tail group
Specific ions bind to __________, and when a certain concentration has
successfully attached, the confirmation of the channel changes, allowing for
ions on the outside to passively diffuse into the cell. - correct ans:Carrier
proteins
What occurs in a dehydration reaction? - correct ans:A water molecule is lost
from the reactant side
