question 78

Multiple Choice

Based on the table of average intron frequency given below, predict the relative order of genome size for these four eukaryotic organisms. $\begin{array}{lc}\text { Organism } & \text { Average Intron Frequency } \\\hline \text { Cryptosporidium parvum } & 0 \\\text { Plasmodium falciparum } & 1 \\\text { Arabidopsis thaliana } & 5 \\\text { Homo sapiens } & 8\end{array}$

• A) Homo sapiens > Arabidopsis thaliana > Plasmodium falciparum > Cryptosporidium parvum
• B) Cryptosporidium parvum > Plasmodium falciparum > Arabidopsis thaliana > Homo sapiens
• C) Homo sapiens > Cryptosporidium parvum > Plasmodium falciparum > Arabidopsis thaliana
• D) Intron frequency cannot be used to predict genome size in eukaryotes.

Definitions:

Carbon

Carbon is a chemical element with symbol C and atomic number 6, essential to all known life forms and the basis of organic chemistry, forming a vast number of compounds including carbon dioxide and organic molecules.

Organic Compounds

Chemical compounds containing carbon atoms bonded to hydrogen atoms with possible addition of other elements such as oxygen, nitrogen, and sulfur; fundamental to all known life forms.

Decomposing Organisms

Organisms, such as bacteria and fungi, that break down dead or decaying organic matter, recycling nutrients back into the ecosystem.

Subatomic Particles

Components of atoms that include protons, neutrons, and electrons, each playing a specific role in atomic structure and behavior.
