Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Human evolution is not linear manner it is a web, in the process of evolution primates lead to the emergence of homo-sapiens, which is distinct from the hominid family.
How did humans evolve?Human evolution is observed in a web manner not linear in evolutionary history primates lead to the homo-sapiens which is distinct from another family of hominids.
The hominid family includes great apes that diverged from the gibbons 15-20 million years ago. Evolution involves some studies, genetic studies, and h behavioral studies.
Anatomically it is observed in Africa 300000 years ago humans appeared, these studies were observed anatomically as the origin of humans.
Therefore human evolution is observed in a web manner not linear.

In what way does walking help The environment? How does it make you feel about the state of our environment?
Answer: Walking plays an important role in improving our quality of life because it helps protect and improve the living environment and natural resources. ... Communities designed to be walkable have the potential to reduce air pollution and greenhouse gases because people may choose to walk or bike rather than drive. Walking plays an important role in improving our quality of life because it helps protect and improve the living environment and natural resources. Improving the environment in turn brings added health benefits that come, for example, from cleaner air, less traffic noise and fewer road accidents.

How is a warm front different from a cold front?
Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather.
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.
Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.
Answer:
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Explanation:
i'm pretty sure
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather. So, the correct option is B.
What are Warm and cold fronts?A warm front forms when a mass of warm air enters a space that previously held cold air. As warm air passes over cooler air, it rises and cools, which can result in the formation of clouds and precipitation. Unlike a cold front, a warm front often brings with it lighter and more widespread precipitation. Warm fronts often bring warm temperatures and high humidity levels.
When a mass of cold air approaches an area that was previously surrounded by warm air, a cold front is formed. When cold air flows into warm air, the warm air is forced to rise rapidly, which can result in thunderstorms and heavy rainfall. More extreme weather changes, such as a sharp drop in temperature and drop in humidity, are often brought about by cold fronts.
So, the correct option is B.

Shawn explains that many studies have shown that directly spraying bees with fungicides doesn't harm them. Are those results consistent with what Shawn has discovered? Explain your answer in a few sentences.
Answer:
Yes.
Explanation:
Yes, the results will be consistent of spraying bees with fungicides because the fungicides affect the growth of fungus not the bees. fungicides are the chemicals kills fungal growth while on the other hand, insecticides will kill the insects such as ants, bees etc. If the Shawn apply insecticide on the bees, it will kill the bees due to its effectiveness so that's why the results of the directly spraying bees with fungicides will always be consistent due to its ineffectiveness.

Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment. Hypotheses generate a scientific experiment, leading to observations, which can be tested through a question. Observations generate a scientific experiment, leading to a hypothesis, which can be tested through a question.
Answer:
The correct answer is - Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Explanation:
In any scientific knowledge development process, scientists need to follow the scientific process in a particular sequence that helps in developing and testing a hypothesis.
The sequence has:
observation: Observation requires you to pay attention to occurrences around
Forming question: on the basis of observation form a question about why that occurrence happens.
Hypothesis formation: The hypothesis is your initial prediction on why that happens.
Experiment: The experiment is being done in order to collect data and analysis so you can test your hypothesis

Answer:gene flow
Explanation:
Drag one of the nucleotides to a corresponding nitrogenous base on one of the two strands. What is
the role of DNA polymerase in this process?
Answer:
This enzyme is responsible for the production of DNA molecules from RNA molecules.
Explanation:
DNA polymerase is a type of enzyme that produces DNA molecules from RNA molecules. The enzymes play a vital role in the replication of DNA in which the enzyme produces two identical copies of DNA from one original DNA molecule. This replication of DNA is very important for cell division as well as growth of the organisms. Without this replication, no mitosis occurs in the body that leads to no growth of the organism so we can say that this enzyme plays a great role in growth of an organism.
The process of the formation of the new from the old DNA is called is replication.
The enzyme responsible for the formation of DNA replication is DNA polymerase.
The things required in the formation of new DNA is as follows:-
DNADNA polymeraseDNA ligaseThe function of the DNA polymerase during the time of DNA replication is to get the nucleotide as a monomer to join together by the DNA ligase. The nucleotide joins together in the 5' to 3' direction.
The drag of one nucleotide from the sequence leads to the mutation. These lead to the form of the infected protein and form the abnormal character.

Why are organisms in lower parts of the food chain not affected but organisms at the top of the food chain are?
Answer:
the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.
Explanation:
Answer:
The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!

Some suggestions for measures that the United States can implement to avoid contributing to greenhouse gases!
Answer:
1. Increase the use of green renewable energies
2. Promote recycling
3. Controlling industrial greenhouse CO2 emissions from the transportation sector
4. encourage the use of non-polluting means of transport (e.g., walking over road transport)
Explanation:
First, renewable energies are energy sources generated naturally without the use of fossil fuels (e.g., solar energy, wind energy, geothermal energy, etc). Thus, these green energies can replace the use of fossil fuels in a sustainable manner, and therefore reduce the emission of greenhouse gases such as carbon dioxide (CO2). Second, recycling can drastically reduce the amount of energy required to synthesize new products and reduces the need for new materials, being thus also useful to reduce CO2 emissions that result from extracting virgin materials. Third, the industries from the transportation sector produce the largest part of greenhouse gas emissions, thereby encourage the use of green energies in this area may represent a good alternative to reduce CO2 emissions. Finally, it is well known that urban transport generates about 40% of all CO2 generated by road transport, and thereby invest in green transport systems such as bicycling and walking may also represent a useful strategy to reduce CO2 emissions.
