New forms of drug-resistant bacteria can evolve quickly because
A
when a drug kills most of the bacteria, the ones left to breed are those that have a natural resistance to the drug.

B
when scientists genetically engineer bacteria they use natural selection.

C
scientists use extinction to selectively breed bacteria.

D
a drug causes mutations in the bacteria, leaving only mutated bacteria left to breed.

Answers

I would say option A, when a drug kills most of the bacteria the ones left to breed are those that have a natural resistance to the drug.

Misuse, abuse, and inadequate infection control and preventive practices all speed up the development of antibiotic resistance. At all societal levels, actions can be made to lessen the effects and contain the spread of resistance. Thus, option A is correct.

What drug-resistant bacteria can evolve quickly?

The experiment demonstrates how simple and rapid it is for bacteria to develop resistance. Resistance levels rose more than 1000-fold in just 11 days, according to Professor Kishony.

Antibiotic usage is the primary contributor to antibiotic resistance. When people take antibiotics, some bacteria are killed, but resistant germs can survive and even multiply.

The incidence of resistant bacteria rises with antibiotic use. The more frequently we take antibiotics, the more likely bacteria are to evolve resistance to them.

Therefore, Within two to three years, new antimicrobial resistance can spread widely. For bacteria that can be selected as both benign commensals and harmful hospital acquired illnesses, resistance issues are particularly serious.

What term describes an allele that is masked or covered/dominated up by another allele?
A. Recessive Allele
B. Dominant Allele
C. Homzygous
D. Heterozygous

Answers

Answer:

B dominant allele

Explanation:

B is the correct answer, I just took the test

Mark Branliest PLEASE

Answer:

Explanation:

A recessive allele is an allele that gets covered up by a dominant allele.

Example -

Lets say that two people were breeding. Brown hair would be the dominant trait, with blonde as a recessive. If the male has the allele Bb, and the female has bb, then you would put these into a table. Your outcome would come as

B b

b Bb bb

So there would be a 50/50 chance of the offspring having brunette or blonde hair.

Which environment will experience the LEAST amount of change over time?

A. an ecosystem with a climax community
B. an ecosystem that is in secondary succession
C. an ecosystem that is in primary succession
D. an ecosystem with only pioneer species

Answers

Answer: D

Explanation: the pioneer species is the first species to live in an environment

An ecosystem with a climax community will experience the least amount of change over time. Therefore, option A is correct.

Why climax community ecosystem experience the least amount of change?

A climax community is a stable community of plants and animals that has reached a state of equilibrium with its environment. In such a community, the number of species and their relative abundance tend to remain relatively constant over time, barring any major disturbances such as fire or human intervention.

In contrast, ecosystems in primary and secondary succession are undergoing significant changes as they transition from bare rock or disturbed land to a stable, self-sustaining community. Ecosystems with only pioneer species may also experience significant changes over time as more complex plant and animal communities develop.

Therefore, option A is correct.

2 organs = kidney , pendex

the two organs you can live without are your kidney and your appendix. you have two kidneys incase there is a complication with one of them, you have a “backup.” your system wouldn’t change too much, you’d live a healthy life. you can also live without your appendix. it’s the most useless organ in the human digestive system. plant eaters rely on their appendix to help process plants , but that organ is not part of the human digestive system. again , you wouldn’t notice any major change. if you do remove a kidney however, it’s be best not to overwork it and take proper care of your body by consuming appropriate amounts of fluids. if you lose both kidneys it’s fatal.

Choose one region on the world map. How does the climate their differ during El Niño and La Niña?

Answers

Answer:What are El Niño and La Niña?

El Niño and La Niña are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth every 3-7 years on average. Together, they are called ENSO (pronounced “en-so”), which is short for El Niño-Southern Oscillation.

The ENSO pattern in the tropical Pacific can be in one of three states: El Niño, Neutral, or La Niña. El Niño (the warm phase) and La Niña (the cool phase) lead to significant differences from the average ocean temperatures, winds, surface pressure, and rainfall across parts of the tropical Pacific. Neutral indicates that conditions are near their long-term average.

Maps of sea surface temperature anomaly in the Pacific Ocean during a strong La Niña (top, December 1988) and El Niño (bottom, December 1997). Maps by NOAA Climate.gov, based on data provided by NOAA View. large versions La Niña | El Niño

What happens during El Niño and La Niña?

During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.

Rising air motion (which is linked to storms and rainfall) increases over the central or eastern Pacific, and surface pressure there tends to be lower than average. Meanwhile, an increase in sinking air motion over Indonesia leads to higher surface pressure and dryness.

Generalized Walker Circulation (December-February) anomaly during El Niño events, overlaid on map of average sea surface temperature anomalies. Anomalous ocean warming in the central and eastern Pacific (orange) help to shift a rising branch of the Walker Circulation to east of 180°, while sinking branches shift to over the Maritime continent and northern South America. NOAA Climate.gov drawing by Fiona Martin.

During La Niña, it’s the opposite. The surface winds across the entire tropical Pacific are stronger than usual, and most of the tropical Pacific Ocean is cooler than average. Rainfall increases over Indonesia (where waters remain warm) and decreases over the central tropical Pacific (which is cool). Over Indonesia, there is more rising air motion and lower surface pressure. There is more sinking air motion over the cooler waters of the central and eastern Pacific.

Generalized Walker Circulation (December-February) anomaly during La Niña events, overlaid on map of average sea surface temperature anomalies. Anomalous ocean cooling (blue-green) in the central and eastern Pacific Ocean and warming over the western Pacific Ocean enhance the rising branch of the Walker circulation over the Maritime Continent and the sinking branch over the eastern Pacific Ocean. Enhanced rising motion is also observed over northern South America, while anomalous sinking motion is found over eastern Africa. NOAA Climate.gov drawing by Fiona Martin.

Between the warm phase (El Niño) and cool phase (La Niña), scientists describe conditions as “ENSO-neutral.” Neutral means that the temperatures, winds, convection (rising air), and rainfall across the tropical Pacific are near their long-term averages.

How are atoms and molecules related?

Answers

Answer:

Explanation:

Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.

Atoms are the building blocks of molecules. A molecule is formed when two or more atoms chemically bond together.

What are they made up of?

Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in energy levels or orbitals. When atoms combine, they share, donate, or accept electrons to achieve a stable electron configuration, forming chemical bonds.

These bonds can be covalent, where atoms share electrons, or ionic, where electrons are transferred between atoms. The arrangement and types of atoms in a molecule determine its chemical properties and behavior. Thus, molecules are composed of specific combinations of atoms held together by chemical bonds.
