Which one of the following statements about the chromosome theory of inheritance is false?
a. genes and chromosomes occur in pairs; one member of each pair is maternally derived, and the other is paternally derived.
b. the arrangement of chromosomes at metaphase of meiosis depends on the arrangement of all other chromosome pairs.
c. genes and chromosomes assort themselves into gametes independently of all other gene pairs and chromosome pairs.
d. at fertilization, each zygote contains two copies of each chromosome and two copies of each gene.
e. none of these

B. The arrangement of chromosomes at metaphase of meiosis depends on the arrangement of all other chromosome pairs.

Explanation:

Each chromosome pair during meiosis arrange itself on the equator of the cell. Here, one homologous chromosome pair arranges itself on the equator independently of other homologous pairs. This random and independent arrangement of chromosomal pairs results in their random and independent segregation during anaphase.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
