some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell. group of answer choices T/F

Answers

Answer 1

True. Antimicrobial resistance occurs when bacteria are able to survive with the presence of a concentration of an antimicrobial agent that would typically kill susceptible bacteria.

Bacteria can become resistant to antibiotics in two main ways: they can develop active pumps that actively remove the drugs from their cytoplasm; or they can alter their cell membranes so the drugs can no longer bind to them. Active efflux pumps are encoded by a wide variety of genes, many of which are present on mobile genetic elements, allowing the spread of resistance across species.

Multidrug pumps, which are capable of transporting multiple classes of drugs, are found in a variety of organisms and are the primary mechanism of antibiotic resistance in many bacterial species. As more drugs are added to the range of drugs a bacterium can resist, the greater its competitive fitness and therefore its chance of survival. As a result, bacterial populations can quickly evolve to resist relatively new antibiotics that have yet to find their way into clinical use.

This rapid increase in antibiotic resistance has proven to be a substantial risk to public health and highlights the need for new antibiotics and prevention strategies.

The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.

Answers

Answer:

A characteristic linked to the alleles that is inherited is the genotype.

Explanation:

The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.

Explanation:

In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.

Explanation:

did the quich check

The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features.

The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.

The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.

Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.

In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
