Answer: Science is a precise interaction, which implies it follows a cautious technique that includes perception and experimentation. Through experimentation, data is gathered that upholds or disproves a researcher's theory. ... Science is upheld by realities and cycles.
Explanation:
Answer:
An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment. Anaerobes may be unicellular (e.g. protozoans, bacteria) or multicellular.

Iris is a farmer who has two fields. Field 1 is near the ocean and Field 2 is far inland. Iris is planting almonds, which require a lot of precipitation. Which field should Iris plant her almonds in?
Field 1, because the closer an area is to a body of water, the more precipitation there is.
Field 2, since inland areas are warmer, which causes greater amounts of precipitation.
Field 2, because the more inland an area is, the more precipitation there will be.
Iris could plant the almonds anywhere since the location of the fields does not affect precipitation.
Answer:
I think it is Option 3: Field 2, because the more inland an area is, the more precipitation there will be.
Explanation:
Whenever it rains, the water evaporates FROM the ocean and the wind blows clouds more towards inland, and it does rain more inland
Answer:
A
Explanation:
There is more moisture near an area that is close to a body of water which causes humidity, which results in precipitation.
So sorry, if I'm incorrect! Good luck with your assessment :)

Which word describes the scientific study of weather and the atmosphere?
meteorology
environmental science
geomorphology
atmospherology
Answer:
I think the answer should be meteorology
Meteorology is the word that describes the scientific study of weather and the atmosphere.
What is weather?Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth.
Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations.

How do you think we could solve the problem of plastic pollution in our oceans?
Answer:
Starting from your own home is the best way to reduce plastic pollution. You can reduce it by stop using plastic bags, water bottles, anything that is plastic. You can reuse things instead. Use less energy. Turn off the lights whenever you leave the house or if you aren't using it. Lastly, conserve water. Don't let the water running if you aren't using it.

what process is illustrated in the figure above?
Answer:
DNA -> RNA is transcription
RNA > Protein is translation
The process illustrated in the figure above is transcription.
What is transcription?Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.
The process of transcription starts when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and starts to gets catalyze the production of complementary RNA.
Large enzymes composed of a lots of dozen subunits, and when active on DNA, they are also so much complexed with other . In many cases, these signal which gene is to be transcribed.
It contains all the information within the code of amino acids and some of them also help in protein synthesis too.
Therefore, the process illustrated in the figure above is transcription.
Therefore, it is transcription.

Why would carbon dating not be a useful way to date a fossil of Coelophysis?
Answer:
Carbon dating cannot be used on most fossils, not only because they are almost always too old, but also because they rarely contain the original carbon of the organism. Also, many fossils are contaminated with carbon from the environment during collection or preservation proceedures.
Explanation:
Carbon dating can not be a useful way to date a fossil of Coelophysis because carbon has a short half life.
Carbon dating and it's usesCarbon dating, which is also called radiocarbon dating, is defined as the method used to determine the age of an object containing organic material with the use of isotope of carbon.
Carbon is used and absorbed by living organism including radioactive carbon-14. When they die, the radioactive carbon that they've accumulated continues to decay.
Because of the short length of the carbon-14 half-life, carbon dating is only accurate for items that are thousands to tens of thousands of years old. Fossil of Coelophysis are much older than this. Geologists must therefore use elements with longer half-lives.
