2. The thyroid gland metabolizes iodine, the most common form of which has a molecular weight of 127 (1271). A physi-
cian wants to use a radioactive isotope of iodine (1231) to
test whether a patient's thyroid gland is metabolizing nor-
mally. Based on what you know about how atoms react,
do you think this physician's plan makes sense or not?

Which class of molecules contains the amino group, nh2 (a) sugars (b) water (c) proteins (d) hydrocarbons

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

Asap what occurs after cytokinesis is completed at the end of meiosis 1?
