BIOL 101 PORTAGE LEARNING GRADED A+
What are the two main components of phospholipids?
(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.
Carrier proteins
What occurs in a dehydration reaction?
A water molecule is lost from the reactant side
What type of passive transport relies on the tendency of salutes to move from an
area of high concentration to an area of lower concentration
Simple diffusion
What are three characteristics of prokaryotic cells?
Size, non-enclosed genetic material, and lack of organelles
True or false; the two major components embedded in a cell membrane are
nucleic acids, and lipids
False: the two main components are phospholipids and proteins.
Which of the bonds formed a relatively weak bond that is easily broken?
Hydrogen bond
The four nitrogenous bases found in DNA are:
Adenine, Thymine, Guanine, Cytosine
Individual living members of a population best describes a:
organism
Each of the following are true of eukaryotes, except:
, Their nucleus is not membrane bound
True or false; rRNA molecules facilitate the assembly of amino acids in a protein
chain
True
_________ plants have cells jointed into tube like structures that allow for the
transport of water and nutrients through the plant body
Vascular
Blight attacks which of the following Eukaryotic kingdoms?
Plantae
Explain how the cell can depict the characteristic of life, order.
The cell is itself highly ordered as it contains organelles, a static cytoplasmic space,
conducts, metabolic processes, and undergoes microscale adaptations.
True or false; Heterotrophic prokaryotes are responsible for releasing oxygen
into the atmosphere and releasing atmospheric nitrogen into a usable form.
False; autotrophic prokaryotes are
Which of the following are true of the eukaryotic kingdom animalia?

encompasses all the other taxa is the _________.
Domain
Each of the following is true regarding the Monera kingdom, except.
Plasmodium can be found in this kingdom
True or false; halo files will thrive and higher temperatures such as volcanoes.
False
halophiles thrive, and high ceiling environments like the dead sea
Thermo files will thrive and higher temperatures such as volcanoes
