Explanation:

The hot spot was stationary, while the plate constantly moved.

The hot spot was fixed in the Pacific plate, while the plate was moving over the hot spot. Because of this, the Hawaiian island were formed.

Answer:The pacific plate is an oceanic tectonic plate. How much did a hot spot and the pacific plate interact to form the Hawailan islands?

Explanation:

The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.

A researcher claims that a newly discovered microorganism is an autotroph. Which observation would support his claim?
Maslowich

Answer:

The microorganism creates its own energy.

Explanation:

Based on the pattern of nutrition, a living organism can either be autotrophic or heterotrophic. Autotrophic organisms are those organisms capable of synthesizing its own food or energy source using light (photosynthesis) or chemicals (chemosynthesis). Heterotrophs, on the other hand, cannot synthesize their own food, hence, they depend on other organisms for energy.

According to this question, a researcher claims that a newly discovered microorganism is an autotroph. For this claim to be true, this means that the microorganism must be capable of CREATING ITS OWN FOOD/ENERGY either by photosynthesis (light) or chemosynthesis (inorganic chemicals).

Oil is most likely to form becauseChoose one:
Luden [163]

B. tiny algae and plankton decomposed under conditions of heat, pressure, and low oxygen.

Explanation:

Oil is most likely to form where tiny algae and plankton decomposed under conditions of heat, pressure and low oxygen.

  Coal will form when plant materials like twigs, leaves and tree trunks decomposed under conditions of heat, pressure and low oxygen.

  • To form oil, algae and plankton will be gathered with sediments in a basin.
  • Rapid burial causes the algae and plankton to be cut off from aerobic environment that would lead to the decay of these organisms.
  • They are buried alive and as the basin subsides, temperature and pressure acts to produce kerogen.
  • Further cracking produces oil and gas.

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.
