Answer:
D: Overuse of antibiotics
Explanation:
Bacteria reproduce and evolve quickly, if you use too much antibiotics, a few of that bacteria would be resistant to it, and reproduce quickly, whilst the non-resistant bacteria would be killed off.
A species of rodent lives in a moist forest
climate. Over time, the elimate becomes drier
and more desertlike, Which adaptation would
most likely improve the chances that the rodent
species
could survive as its environment
changes?
A. having dark hair and small ears
B. living above ground in damp areas
C. being able to eat only one type
of berry
D. being able to eat plants that survive in the
changed environment
The possibility that a rodent species may have survived because of a change in its environment that is capable of eating plants that survive the changed environment. So, the correct option is (D).
What is Adaptation?Adaptation is defined as the process by which a species adapts to its environment as a result of natural selection acting on variation over many generations.
Organisms are adapted to their environment in their structure, physiology, and genetics, in their locomotion or dispersal, in their means of defense and attack, in their reproduction and development, and in other respects.
It is described as the ability of an organism to adapt to its environment and change through time, referring to the term "adaptation theory", known as the "survival of the fittest" idea. In this instance, rodents become able to eat plants that survive the changed environment.
Thus, the possibility that a rodent species may have survived because of a change in its environment that is capable of eating plants that survive the changed environment. So, the correct option is (D).

What does biodiesel produce in higher amounts? biodiesel produces higher amounts of .
Biodiesel produces greater amounts of benefits in its use than fossil fuels.
Is biofuel better than fossil fuels?Burning biodiesel generates 98% less sulfur, which is responsible for acid rain and respiratory problems, 78% less greenhouse gases and 50% less particulate matter (black smoke), which is also responsible for respiratory problems.
In addition, biodiesel has a cetane number equivalent to diesel (same detonating or self-igniting effect), has an average oxygen content of around 11% and has a higher flash point than conventional diesel.
With this information, we can conclude that biodiesel produces greater amounts of benefits in its use than fossil fuels.

B. The new plants inherited dominant genes for yellow flower color.
C. The soil the plants were in caused the flowers to turn yellow.
D. The new plants received more sunlight than the parent plants.
Answer:
B. is the answer.
Yellow(Yy) is a dominant allele, and although white(ww) is inherited from the parent gene, Yy, white is a recessive gene. That means it is most unlikely to be visible through phenotype(term for visible characteristics).
what happens if u lose brain cells
Answer:
If you actually began losing brain cells then you could begin to have difficulties with motor and other skills. It may affect your nervous system, or pretty much anything else in your body depending on which ones you lose, meaning that your body may stop functioning properly. You may lose your ability to remember things or perform everyday tasks. It is true that some neurons die as people age because of the waste they accumulate that causes them to lose their function and degenerate. This can affect some elderly people by appearing as conditions like Alzheimer's, Dementia, or Parkinson's. While this is a natural event, some injuries or damage to the brain due to accidents, or the use of substances, cause destruction or deterioration in younger, healthier brains.

Select the correct answer. mathew claims that people should invest in alternative sources of energy rather than burning fossil fuels. he has put together two graphs as evidence. the first compares how human use of fossil fuels affects atmospheric carbon dioxide levels, and the second shows how land-ocean temperatures on earth have changed over time. which statement correctly supports his claim based on evidence from the graphs? a graph showing the increasing trend of carbon emissions from 1800 to 2004, a graph showing the increasing trend of annual mean temperature from 1880 to 2015 a. more carbon in the atmosphere likely absorbs more heat energy, thus increasing the temperature. b. petroleum should replace natural gas, since it releases less carbon dioxide. c. burning coal does not contribute to a rise in carbon dioxide or temperature. d. carbon dioxide emissions from burning fossil fuels has decreased over time. e. the graphs show no possible correlation between burning fossil fuels and increasing temperatures.
The evidence from the graphs is that more carbon in the atmosphere is likely to absorb more heat energy, thus raising the temperature.
Why does carbon raise the temperature?The feature is important because the effect of sunlight on the Earth's surface, including the oceans, is reflected in the form of infrared rays. By absorbing this radiation, the gases heat up the entire atmosphere as if they were a blanket that keeps the planet warm.
Whit this information, we can conclude that the evidence from the graphs is that more carbon in the atmosphere is likely to absorb more heat energy, thus raising the temperature.

Write 2-3 sentences to show your understanding of how the following words connect together in the water cycle: Evaporation, Condensation, Precipitation, Freezing, Melting
The water cycle is responsible for the regulation of temperature in our surroundings. It modifies the weather and causes rain. It is important for the circulation of various minerals throughout the environment.
What do you mean by the Water cycle?The water cycle may be defined as the continuous process by which water is circulated throughout the earth and the atmosphere through evaporation, condensation, precipitation, vaporization, etc.
Evaporation: It is a process through which water changes its liquid state into a gaseous or vapor state. It is the first step of the water cycle.
Condensation: It is the opposite as compared to evaporation. It involves the process of water vapor changing back into liquid water.
Precipitation: This process is responsible for the rain to occur. It involves the gathering of water vapor to synthesize bigger and bigger droplets of water.
Freezing: Freezing is responsible for the formation of ice in glaciers, at low temperatures, etc. It involves the process of changing liquid water into a solid form.
Melting: This process is just the opposite of freezing. Hence, it involves the transformation of a solid form of water which is ice into a liquid form.
Therefore, it is well described above.

How did the bacteria population become more resistant in Addie and our community?
Answer:
it's due to global warming and the increasing of population
also some how deforestation also
Answer: The environmental change put selection pressure on the population of the bacteria so that some trait variations had a competitive advantage for surviving over time.
Explanation: So, in Addie’s case, the environmental change was the antibiotics. The antibiotics led to the weaker bacteria to die off while the stronger bacteria reproduced and grew larger in population. This is called selection pressure. So to sum it all up, the bacteria population became more resistant because of the pressure selection out into them by the antibiotics. So, the weaker bacteria died off and the stronger one grew larger and larger, becoming antibiotic resistant. Sorry if I’m too late but I hope this clarifies your question!
