the kingdom monera has been separated into two domains, the archaea, and the bacteria. which of the following was most important in prompting scientists to change the way these organisms were classified?

Answers

Prokaryotic nature (does not have a membrane-bound nucleus) is the main characteristic used in classifying kingdom monera into archaea and bacteria.

How many types of kingdom monera?

Kingdom monera is classified into three sub-kingdoms - Archaebacteria, eubacteria, and cyanobacteria.

What are the Characteristics of Monera ?

They contain 70S ribosomes DNA and is not bound by a nuclear membrane. It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, and centrosome. They reproduce by binary fission or budding. Lives in anaerobic or aerobic conditions.

They are generally unicellular. These are environmental decomposers and mineralizers. They have different modes of nutrition - autotrophic (photoautotrophs or chemoautotrophs), heterotropic, parasitic, saprophytic, and symbiotic.

Examples of monera include: blue-green algae (Cyanobacteria), cocci-shaped bacteria- Streptococcus, bacillus-shaped bacteria- E-coli, vibrio-shaped- vibrio cholera, spiral-shaped bacteria- Trepanoma palladium.

Lysogenic bacteriophages contribute to bacterial virulence because bacteriophages.

Answers

Because they provide novel gene sequences to their host bacterium, lysogenic bacteriophages increase the pathogenicity of bacteria.

What distinguishes lysogenic bacteriophages from lytic ones?

The phage replicates during the lytic cycle before lysing the host cell. Phage DNA enters the host genome during the lysogenic cycle and is passed on to next generations. The prophage may excise and enter the lytic cycle as a result of environmental stressors including hunger or exposure to hazardous substances.

What kind of virus qualifies as lysogenic?

The (lambda) virus, which infects the E. coli bacterium, is a prime example of a lysogenic bacteriophage. Sometimes viruses that infect plant or animal cells experience infections when they stop generating virions for a considerable amount of time.

https://brainly.com/question/28386236

#SPJ4

Lysogenic bacteriophages contribute to bacterial virulence because bacteriophages can carry and transfer virulence genes to the bacterial host. When a bacteriophage infects a bacterium and integrates its genetic material into the bacterial chromosome, the resulting lysogen (bacterium with integrated phage DNA) can carry additional genes that encode virulence factors.

Virulence factors are molecules or proteins that enhance the ability of a bacterium to cause disease in a host organism. These factors might include toxins, adhesion proteins, immune evasion molecules, or other elements that help the bacterium establish infection and evade the host's immune responses.

When a lysogenic bacteriophage carries virulence genes, it effectively turns a harmless or less virulent bacterium into a more pathogenic one. This phenomenon has been observed in several bacterial pathogens, such as the bacterium Vibrio cholerae, which causes cholera. In these cases, the presence of lysogenic phages can significantly increase the severity of the disease caused by the bacteria.

Overall, lysogenic bacteriophages play a crucial role in bacterial evolution and adaptation to their environments, including their interactions with hosts and their ability to cause disease.

How do heterotrophs obtain energy? how is this different from how autotrophs obtain energy?.

Answers

Heterotrophs must obtain their energy from other living things, whereas autotrophs can harness the sun's energy.

Organisms can be categorized into two main groups: autotrophs and heterotrophs, based on how they receive energy and nutrients. Because they can manufacture their own food from raw materials and energy, autotrophs are referred to as producers. Numerous varieties of bacteria, plants, and algae are examples.

When an organism uses other plants or animals for food and energy, it is referred to as a heterotroph. Heterotrophs are a group of organisms that are found in the second and third tiers of a food chain, and their name derives from the Greek terms hetero, which means "other," and troponin. Each food chain is composed of three trophic levels, which describe an organism's role in an ecosystem. Autotrophs, which include plants and algae, make up the first trophic level of the food chain. Herbivores—animals that eat plants—dwell on the second level. Omnivores and carnivores (animals that eat meat) live on the third level (animals that consume both plants and meat). Primary consumers (herbivores) and secondary consumers (carnivores and omnivores) are both heterotrophs, which means "nutrition," whereas primary producers are autotrophs.

Samantha invested $1000 in an account that pays 5% interestcompounded annually. Assuming no deposits or withdrawals aremade, find how much money Samantha would have in the account 18years after her initial investment. Round to the nearest tenth (ifnecessary). situation where middle polarizer is rotated. suppose the middle polarizer is rotated at 100 revolutions per minute. how many times per minute will you observe the light change from bright (max intensity) to dark (min intensity)? this effect, although not normally done with mechanical rotation, is the basis for making optical modulators that are used in high-speed digital communication systems. can you please explain? thanks
