The equation that represents a fusion reaction is ²₁H + ²₁H = ⁴₂He and the correct option D.
A fusion reaction is a type of nuclear reaction that involves the merging or combining of two or more atomic nuclei to form a heavier nucleus. This process releases a significant amount of energy.
In fusion reactions, the atomic nuclei overcome the electrostatic repulsion between positively charged protons and come close enough for the strong nuclear force to bind them together. This typically occurs at extremely high temperatures and pressures, such as those found in the core of stars or in experimental fusion reactors.
The most well-known fusion reaction is the fusion of hydrogen isotopes, deuterium and tritium, to form helium. This reaction is the primary process that powers the Sun and other stars, and it is also the focus of research efforts to achieve controlled nuclear fusion for practical energy production on Earth.
Thus, the ideal selection is option D.

what process is illustrated in the figure above?
Answers
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.

Why would carbon dating not be a useful way to date a fossil of Coelophysis?
Answers
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.

A model of tin, an element with the atomic number 50, is shown here. The valence electrons are modeled here in this image. Which statements are supported by the information in the model? Select ALL That apply.
A) Tin needs four more electrons to complete its outer shell.
B) Tin has no neutrons in the nucleus, as is shown in the model.
C) Tin is highly reactive because it only has four valence electrons.
D) Tin is negatively charged because it more electrons than protons.
E) Tin has a low reactivity because it has full inner shells of electrons.
Answers
Answer: A and C
Explanation:
According to the electronic configuration, tin needs 4 more electrons to complete its outer shell.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

"Scientists make synthetic substances by arranging atoms and molecules in the lab. They use what they know about different types of atoms and molecules to arrange them and make the kinds of substances they want.
Synthetic medicines aren’t any different at the atomic level from the natural medicines found in the rainforest. After all, molecules are just molecules—whether they’re made in nature or in a lab, the same types of atoms arranged in the same ways always form the same molecules that behave in the same ways."
At the atomic level, are synthetic medicines different from natural medicines?

Although herbal medicines are less potent in comparison to synthetic drugs in some cases but still these are consider less toxic or having less side effect in contrast to synthetic drugs.

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.
Answers
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.

Which word describes the scientific study of weather and the atmosphere?
meteorology

atmospherology
Answers
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.

Ecosystems are "dynamic". this means that the ecosystem change
over time.
during the ice ages , glaciers once covered areas that are tropical rainforests today. both natural forces and human actions cause ecosystem to change
if there is a big ecosystem change caused by natrual forces or human actions , the plants and animals that live there might be destroyed. or they may be foreced to leave.
over time a new community will develop and then that community may be replaced by another.
primary succession is the type of eological succession that happens on new lands, lands where life has not yet been existed. primary succession can take place after lava flow cools and hardens into new land or glacier recedes exposing new land.
secondary succession is the type of succession happens after something destroys the habitat, such as a flood or other natrual disaster. abandoning a field that was once used for agriculture can also lead secondary successionn
