Answer:

Option (B)

Explanation:

Meiosis is usually defined as a biological process in which a single cell generates twice in order to form four new cells that comprises the genetic parent characteristics. It leads to the production of genetic diversity. This process results in the formation of sperms in males and eggs in females, where both are the sex cells responsible for the process of reproduction.

Thus, the correct answer is option (B).

What is the principle of common decent? Use your OWN words plz?? <3

Natali5045456 [20]

Answer:

The principle of common descent states that all organisms in the world exist because of a common ancestor which gave rise to all the life seen on Earth. The organisms which are more closer to one another might have a common ancestor in the near past as compared to other organisms. The organisms which share distant common ancestors have less common characteristics. This principle has led us to form the basis for the formation of evolutionary biology.

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.

Why does sound travel slower in cold air

natka813 [3]

The speed of sound is greater in hot air than it is in cold air. This is because the molecules of air are moving faster and the vibrations of the sound wave can therefore be transmitted faster. This means that when sound travels from hot air to cold air or from cold air to hot air it will refract.

andrew11 [14]

Answer:D

Explanation:

This isn’t B, because it’s only one species. It isn’t C, because it is one population, and A doesn’t make sense due to how they are of course organisms. D is your best bet.
