The diagram below represents some changes that took place in a bacterial population recently exposed to an antibiotic.Which statement would best explain the presence of bacteria on day 4?A) A bacterial population cannot survive exposure to antibiotics.B) This bacterial population cannot survive exposure to this antibiotic.C) Bacteria can change whenever it is necessary to survive antibiotic treatment.D) Some of the bacterial population was resistant to this antibiotic.
About the question:
You will find the diagram used to answer the question in the attached files.
Answer:
D) Some of the bacterial population was resistant to this antibiotic.
Explanation:
The term resistance refers to an inheritable change in a population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach a desired effect on the target population.
The excessive use of antibiotics on the bacteria population leads to the fixation of new mutated genes -by natural selection-. The mutated genes make these cells even more resistant to the drug.
In the exposed example we have,
Day 1 ⇒ a big population of white bacteria and only one black cell, probably carrying mutated genetic material.The population was treated with antibiotics.
Day 2 ⇒ there are fewer white bacteria and three black cells. This means that white bacteria are dying, while the black ones are reproducing.The mutated phenotype gets to survive under the effects of the chemical.
Day 3 ⇒ There are no more white bacteria. Only the black population survived and keeps reproducing.The mutated bacteria reproduce with the capability of tolerating the antibiotic dose that is usually used to destroy a population of white bacteria.
Day 4 ⇒ Black bacteria got to survive a produce a big population. Remember that bacteria follow the exponential growth model, meaning that their reproductive rate is too high. This black population survived the antibiotic action and reproduced at high rates.I'm giving my 1532 points away.

Fossils of animals the size of goats were dated at 5 million years old. Similarly, fossils of larger animals were dated at 3 million years old. Both animals were similar in body structure to today's horses. Using these data, which inference can scientists make?Immersive Reader
The animals were probably ancestors of today's horses.
The animals had no relationship to one another.
Today's horses and these animals probably lived together at some time in the past.
Today's horses are faster than these animals were.
Answer:
THE ANSWER IS: A it makes the most sence.
Explanation:
The animals were probably ancestors of today's horses. Thus option A is correct.
What are fossils?Fossils are the preserved remains, traces, or traces of living things from a bygone geological epoch. Bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants are some examples of the fossils.
Paleontology is the study of fossils, their ages, how they formed, and their evolutionary importance. Specimens older than 10,000 years are usually considered fossils. The oldest fossils are about 3.48 to 4.1 billion years old.
There are many processes that lead to fossilization, including permineralization, casting and molding, true mineralization, displacement and recrystallization, impression, carbonization, and bioimulation.
Therefore, if both fossils have similar structure then the animals were probably ancestors of today's horses.

2. Energy flows through Earth's spheres and changes along the way. Describe how energy is conserved in these systems. (2 points)
Answer:
Teaching about energy and physical processes is supported by 7 key concepts:
2.1 Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.
2.2 Sunlight, gravitational potential, decay of radioactive isotopes, and rotation of the Earth are the major sources of energy driving physical processes on Earth. Sunlight is a source external to Earth, while radioactive isotopes and gravitational potential, with the exception of tidal energy, are internal. Radioactive isotopes and gravity work together to produce geothermal energy beneath Earth's surface. Earth's rotation influences global flow of air and water.
2.3 Earth's weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth's surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.
2.4 Water plays a major role in the storage and transfer of energy in the Earth system. The major role water plays is a result of water's prevalence, high heat capacity, and the fact that phase changes of water occur regularly on Earth. The Sun provides the energy that drives the water cycle on Earth.
2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life. Energy drives the flow of carbon between these different reservoirs.
2.6 Greenhouse gases affect energy flow through the Earth system. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of Earth. These gases play a major role in determining average global surface temperatures. When Earth emits the same amount of energy as it absorbs, its average temperature remains stable.
2.7 The effects of changes in Earth's energy system are often not immediately apparent. Responses to changes in Earth's energy system, input versus output, are often only noticeable over the course of months, years, or even decades.

A laboratory investigation examined the growth rate of fruit flies in culture jars over time. The fruit flies were grown in an artificial
medium containing nutrients and moisture. They were enclosed in a culture jar of a defined size. Initially, there were ten fruit flies
in the experiment. The population reached 75 over the course of four weeks. However, after eight weeks, the population size
leveled off and then decreased. Survival of fruit fly larvae declined after eight weeks. Which hypotheses are supported by the
information in this scenario? Select ALL that apply?
A)
The older fruit flies were unable to reproduce
Scientific
Calc
B)
The carrying capacity was exceeded by the fly population
Food was abundant for the first four weeks of the experiment.
D)
The fruit flies were unable to survive in a laboratory setting
E)
The carrying capacity decreased when no new food was added to the
culture jars.
Answer: B, D, E
Explanation:
USA test prep said it
The carrying capacity was exceeded by the fly population as Food was abundant for the first four weeks of the experiment.The fruit flies were unable to survive in a laboratory setting. The carrying capacity decreased when no new food was added to the culture jars. Options B,D and E are correct.
What is the reason of choosing fruit flies ?
The reason of choosing fruit flies is because of their big growth rate along with the smaller life cycle.
The carrying capacity that is the fruit flies were able to multiply faster and faster because the food source that is the nutrition that was given to the flies was in big amount thus the cycle could continue.
Fruit flies are able to reach a limit of the growth rate when they are in natural habitat when they reach the artificial setting then they are not able to get into the same growth rate.
The carrying capacity decreased when no new food was added to the
culture jars. With time when the nutrition source that was being added to the jars got decreased the flies stopped growth rate and reached a declining number as well.

In what ways do humans rely on healthy ecosystems? Use the words "Natural Resources" and "Ecosystem Services" in your answer.
How does the loss of biodiversity impact ecosystem health?
Explain the main causes of biodiversity loss.
Answer:
Due to needs of resources.
Explanation:
Humans rely on healthy ecosystems because human needs resources such as food, clean water, disease regulation and climate regulation etc which can be provided by the ecosystem. If the ecosystem is healthy, human can harvest or get more resources from the ecosystem. The biodiversity present in the ecosystem makes the ecosystem healthy and is responsible for the presence of more resources so loss of biodiversity greatly impact ecosystem health. Climate change, pollution, destruction of habitats and invasive species are the main causes of loss of biodiversity in the ecosystem.
When rocks and minerals are worn and broken down into small pieces by water, wind, or ice, the resulting particles are called ?
Sand i think? Maybe dust tho if sand isnt an option
Explanation:
The resulting particles are called sediments.
Rocks and minerals are disintegrated by agents of weathering such as water, glacial (ice) and wind. When these agents of weathering act on rock and minerals, they break down into small particles. These small pieces of weathered rocks and minerals is what is called sediments.
Sediments are pieces of weathered materials from rocks and minerals which can be carried by agents of erosion and deposited in another location.
Thus, the resulting particles from the breakdown of rocks and minerals are called sediments.

Soil organisms, such as mycorrhizal fungi, impact the rate of succession in ecosystems. Mycorrhizal fungi have a mutualistic relationship with various species of plants and increase the plant growth and survival. Sand dunes often lack mycorrhizal fungi, and a researcher wanted to determine the effect of adding mycorrhizal species to sand on disturbed beaches on grass growth. The researcher set up various mycorrhizal communities at disturbed beaches in different locations on the east coast of the United States. Identify the independent variable in the study.
Answer:
The amount (number) of mycorrhizal fungi
Explanation:
In a scientific experiment/study, the independent variable is the variable that isn't changed by other variables, while the dependent variable is the variable that is being measured during the experimental procedure. The independent variable is manipulated by the researcher (in this case, the amount of mycorrhizal fungi), thereby affecting the dependent variable (in this case, grass growth). In consequence, a variable is dependent because it 'depends' on the independent variable.
