In identical twins, alleles are identical and the order of the bases on the interior of the DNA molecule is identical (Options C and E). It is because genetic material is identical.

<h3>What are identical twins?</h3>

Identical twins refer to individuals produced by the same zygote cell, i.e., they are monozygotic twins.

Since these individuals are produced by the same zygote cell, their genetic material (DNA) will be identical.

Identical twins are useful to understand the exact role of genetics and environment in a given phenotypic trait.

The many volcanoes located along the edge of the Pacific Ocean make up the Ring of Fire. How does subduction play a role in the

Juli2301 [7.4K]

Answer:

The Ring of Fire contains approximately 850–1,000 volcanoes that have been active during the last 11,700 years (about two-thirds of the world's total). The four largest volcanic eruptions on Earth in the last 11,700 years occurred at volcanoes in the Ring of Fire.

Not one of the ways that bacteria have adapted to become resistant to antimicrobial agents.

Dominik [7]

Answer:

Explanation:

An antimicrobial agent is a natural or synthetic chemical that kills or inhibits the growth of microorganisms. Bacteria have a mechanism of transferring genomic material called horizontal gene transfer, the movement of genes between cells that are not direct descendants of one another. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. One of the characteristics usually acquired is the resistance to antibiotics.

Three mechanisms of genetic exchange are known in prokaryotes:

(1) transformation, in which free DNA released from one cell is taken up by another; (2) transduction, in which DNA transfer is mediated by a virus; and (3) conjugation, in which DNA transfer requires cell-to-cell contact and a conjugative plasmid in the donor cell.

Examples of genes transferred by transducing bacteriophages include multiple antibiotic resistance genes among strains of Salmonella enterica serovar Typhimurium, Shiga-like toxin genes in Escherichia coli, virulence factors in Vibrio cholerae, and genes encoding photosynthetic proteins in cyanobacteria.

Conjugative plasmids use a mechanism to transfer copies of themselves and the genes they encode, such as those for antibiotic resistance, to new host cells.
