Territoriality causes animal aggressive displays and sounds.

Increased population leads to a faster depletion of natural resources.

Competition for resources among native and nonnative species will destabilize the ecosystem.

DNA replication is necessary to maintain the same number of chromosomes in daughter cells as in the parent cell.

The mRNA sequence produced from the DNA section TAG CAG TAC is AUC GUC AUG.

DNA replication is required for both mitosis and meiosis.

Chemicals can increase cancer risk by causing cell mutations.

The sequence of nucleotides differs in dog and fly DNA.

Physical characteristics are the basis for the earliest classification systems.

Waxes belong to the lipid group of organic molecules.

DNA contains the instructions for making proteins.

Oxygen bubbles are produced during photosynthesis in Elodea.

Chloroplasts are the structures in plant cells where food production occurs.

In the same organism, different cells activate different parts of their DNA resulting in different shapes and functions.

Sweating during exercise regulates body temperature.

Colchicine disrupts mitosis, stopping normal cell division.

Animals obtain nutrients by consuming other organisms or their byproducts.

Reintroducing wolves can help regulate prey populations, promoting ecosystem balance through natural checks and balances.

Both mitosis and meiosis require DNA replication before their respective divisions.

Environmental factors, like the soil type, affect the expression of flower color genes in genetically identical plants.

Bacteria are transgenic organisms used for oil spill cleanup.

Resistant bacteria have survived and out reproduced nonresistant bacteria, leading to antibiotic effectiveness decline.

Genetic differences between surviving and killed insects lead to insecticide ineffectiveness over time.

Multicellular, eukaryotic, autotrophs belong to the kingdom Plantae.

Carbohydrates are difficult to digest without salivary amylase.

At high temperatures, the shape of the enzyme changes, thus decreasing the rate of biochemical reactions.
