For a species with a diploid number of 18 chromosomes, indicate how many chromosomes will be present in the somatic cell nuclei of individuals that are: a. haploid b. triploid c. tetraploid d. trisomic e. monosomic

a. haploid: 9

b. triploid: 27

c. tetraploid: 36  

d. trisomic: 19

e. monosomic: 17

Explanation:

A haploid cell contains a single set of chromosomes (1n), which is the same number of chromosomes found in eggs and sperm cells. Moreover, triploidy is a genetic condition in which there are three sets of chromosomes (3n) in single cells, while a tetraploid cell contains four complete sets of chromosomes (4n). Finally, a trisomy is an abnormal chromosomal condition characterized by the presence of an extra chromosome (i.e. three instead of two), while monosomy is characterized by the presence of only one chromosome (i.e., one instead of two).

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
