Answer:

Nicholas Steno

Explanation:

Nicholas Steno who was a Catholic priest establish relationship between sedimentary rock layers otherwise called stratigraphy.

Stratigraphy is a branch of geology that deals with the study of rock layers. He established theoretical law of stratigraphy by introducing law of superimposition, principle of original horizontality and the principle of lateral continuity in 1669 work of fossilization of organic matter sediments.

the size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantag
professor190 [17]

Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.

Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill. Any dangerous microbial agent, including bacteria, viruses, protozoa, fungi, and helminths, might be considered a pathogen.

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 <em>horizontal gene transfer</em><em>, the movement of genes between cells that are not direct descendants of one another</em>. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. <u>One of the characteristics usually acquired is the resistance to antibiotics</u>.

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 <em>Salmonella enterica </em>serovar <em>Typhimurium</em>, Shiga-like toxin genes in <em>Escherichia coli</em>, virulence factors in <em>Vibrio cholerae</em>, 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.

What is the key to having a long term, sustainable food supply in the new millennium
natulia [17]

Answer:

the correct answer is B) Hydro Pods  

Explanation:

Hydroponic Pods are miniature farms that can fit indoors even in a rented apartment and which enables one to grow their foods indoors.

It is designed to enable one to grow plants using water, and nutrients only. No soil is required. Often, the plant's nutrition comes in already made solutions. This system of farming occupies far less space than traditional farming methods.

How does climate change affect pollinators?
sashaice [31]

According to Esaias, the changes aren’t just dramatic, they’re also kind of scary. The fertility of most flowering plants, including nearly all fruits and vegetables, depends on animal-mediated pollination. As the pollinators move from flower to flower for nectar--a high-energy, sugary enticement—the plants dust them with pollen, which the animals transfer from flower to flower.
