ATI TEAS 7 life and physical sciences
List the six components of the biological hierarchy of the body, from the least to most
complex. -
chemicals, cells, tissues, organs, organ system, organism
which of the following describes the function of the ribosome? -
protein synthesis
because muscle cells require large amount of energy to function correctly, which organelles
would be abundant in those types of cells? -
mitochondira
which of the following organelles houses the genetic material? -
nucleus
write to to three sentences to define and differentiate mitosis and meiosis. -
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
what does macromolecule include? -
carbohydrates, lipids, proteins, and nucleic acids
what are the 4 basic types of tissue? -
1) muscular tissue
2) nervous tissue
3) connective tissue
4) epithelial tissue
what is the function of the cell (plasma) membrane? -
maintains cells environment through the process of selective permeability
what is the function of the cytoplasm? -
supports and suspends structure inside the cell membrane; transfers materials required
for cellular processes
what is the function of the Golgi apparatus? -
processes proteins and lipid molecules
what is the function of the lysosome? -
aids in digestion and recycling of old cell materials; may help destroy invading
viruses and bacteria
What is the function of the mitochondria? -
generates chemical energy in the form of ATP molecules
what is the function of the nucleus? -
1|Page
, 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? -
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? -
contains ribosomes; synthesizes and processes proteins in the cell
what is the function of the smooth endoplasmic reticulum? -
does not contain ribosomes; synthesizes and concentrates lipids in the cells.
Inactivates toxins and harmful metabolic products
what is the function of the vacoule? -
serves as storage for a variety of elements, such as water, toxins and carbohydrates
what are the 5 phases of mitosis? -
1. interphase
2. prophase
3. metaphase
4. anaphase
5. telophase
during what phase of mitosis do chromosomes condense and visible chromosome appear? -
prophase
during what stage of mitosis are chromosomes pulled apart to the poles; and cell division
begins? -
anaphase
which of the following nucleotides pairs with adenine in DNA? -
thymine
which of the following is the number of chromosomes found in a human cell? -
46 (23pairs)
which of the following statements about nucleotides and genes is correct? -
nucleotides form strings of DNA that make up genes
which of the following is the name for a segment of DNA that codes for a protein? -
gene
where are genetic information contained? -
chromosomes
what are organisms with nuclei called? -
eukaryotic
what are organisms without a nuclei called? -
