ATI TEAS 7 LIFE AND PHYSICAL
SCIENCES
List the six components of the biological hierarchy of the body, from the least to most
complex. - Correct Answers -chemicals, cells, tissues, organs, organ system, organism
which of the following describes the function of the ribosome? - Correct Answers -
protein synthesis
because muscle cells require large amount of energy to function correctly, which
organelles would be abundant in those types of cells? - Correct Answers -mitochondira
which of the following organelles houses the genetic material? - Correct Answers -
nucleus
write to to three sentences to define and differentiate mitosis and meiosis. - Correct
Answers -in mitosis, cells duplicate for tissue growth and repair. One cell divides into
two genetically identical daughter cells. Whereas, in meiosis the nucleus of a germ cell
splits through two fissions into four sex cells, each with half the genetic material of the
original
where is glycogen stored? - Correct Answers -liver and muscles
what are polysaccharides? - Correct Answers -carbohydrate molecules formed by large
numbers of linked monosaccharides. Animals store the monosaccharide glucose in the
form of polysaccharide glycogen
what makes up a lipid? - Correct Answers -lipids are formed from a linear arrangement
of carbon atoms and hydrogen atoms called "fatty-acid chains" that are attached to a
glycerol molecule. Lipids tend to be hydrophobic and non polar.
what are the 4 groups of lipids? - Correct Answers -1) fats (triglycerides) & oil
2) phospholipids
3) waxes
4) steroids
what enzyme is produced and secreted by stomach cells and initiates protein digestion
in the stomach? - Correct Answers -pepsin
, what does macromolecule include? - Correct Answers -carbohydrates, lipids, proteins,
and nucleic acids
what are the 4 basic types of tissue? - Correct Answers -1) muscular tissue
2) nervous tissue
3) connective tissue
4) epithelial tissue
what is the function of the cell (plasma) membrane? - Correct Answers -maintains cells
environment through the process of selective permeability
what is the function of the cytoplasm? - Correct Answers -supports and suspends
structure inside the cell membrane; transfers materials required for cellular processes
what is the function of the Golgi apparatus? - Correct Answers -processes proteins and
lipid molecules
what is the function of the lysosome? - Correct Answers -aids in digestion and recycling
of old cell materials; may help destroy invading viruses and bacteria
What is the function of the mitochondria? - Correct Answers -generates chemical
energy in the form of ATP molecules
what is the function of the nucleus? - Correct Answers -holds genes that carry
hereditary information; regulates the activity of the cells. Also, nucleolus assembles
RNA and proteins into ribosomes.
what is the function of the ribosomes? - Correct Answers -synthesize proteins (many
are found on the surface of the rough endoplasmic reticulum although some can be
free-floating in the cytoplasm)
what is the function of the rough endoplasmic reticulum? - Correct Answers -contains
ribosomes; synthesizes and processes proteins in the cell
what is the function of the smooth endoplasmic reticulum? - Correct Answers -does not
contain ribosomes; synthesizes and concentrates lipids in the cells. Inactivates toxins
and harmful metabolic products
what is the function of the vacoule? - Correct Answers -serves as storage for a variety
of elements, such as water, toxins and carbohydrates
what are the 5 phases of mitosis? - Correct Answers -1. interphase
2. prophase
3. metaphase
4. anaphase
5. telophase
