ALREADY PASSED GRADED A+
◉ A runner produced hypotonic sweat while running a marathon in
hot weather. After the race, he drank large volumes of water. As a
result of the water intake, his body cells will
Select one:
a. shrink.
b. swell.
c. crenate.
d. shrivel.
e. not change. Answer: b. swell.
◉ Which mature cells do not have a nucleus?
Select one:
a. columnar cells of upper respiratory tract
b. spermatozoa
,c. columnar cells of small intestines
d. red blood cells
e. macrophage (large, mobile white blood cell). Answer: d. red blood
cells
◉ The structural RNA of ribosomes is a
Select one:
a. pre-mRNA.
b. proenzyme.
c. gene.
d. ribosomal RNA (rRNA).
e. codon.. Answer: d. ribosomal RNA (rRNA).
◉ A mRNA containing introns is a
Select one:
a. pre-mRNA.
b. proenzyme.
c. gene.
d. ribosomal RNA (rRNA).
e. codon.. Answer: a. pre-mRNA.
,◉ What are introns and exons?. Answer: Simple definition:
Introns: some internal segments of RNA that do not code for
protein.
Exons: parts of the transcript that remain and code for protein.
More In-depth:
Introns are non-coding regions (intervening regions) that do not get
translated to amino acid. Introns get spliced out (removed) during
pre-mRNA processing.
Exons are the coding regions of a eukaryotic gene that get translated
to amino acid.
◉ What is mRNA?. Answer: an intermediate message that is
translated to form a protein; Messenger RNA
◉ What is RNA?. Answer: single-stranded nucleic acid that contains
the sugar ribose; Ribonucleic Acid
◉ What type of process conducts nerve impulses toward the cell
body?
Select one:
a. mesoderm
b. neuroglia
, c. membrane
d. dendrite
e. pseudostratified columnar epithelium. Answer: d. dendrite
◉ Cells that break down bone are called
Select one:
a. osteoblasts.
b. osteoclasts.
c. osteocytes.
d. fibroblasts.
e. chondroblasts.. Answer: b. osteoclasts.
◉ What are osteocytes?. Answer: mature osteoblasts or bone cells.
◉ What are osteoblasts?. Answer: bone forming cells
◉ What type of tissue forms linings or coverings?
Select one:
a. epithelial tissue
b. connective tissue
