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.

Answer:
in 1988, a forest fire destroyed much of yellowstone park.This photo, taken 17 years later,show that the forest is gradually growing back, small grasses first grew here and are now being replaced by small trees and shrubs, this is an example of the later stages of secondary succession.
The early stages of succession after a forest fire are shown in these pictures. taken four years after the fire. they show the charred remains of the original forest as well as the small grasses and shrubs that are beginning to throw in the back area.
During a volcanic eruption,molten lava flows over the ground and into the water. after the eruption is over the lava cools and hardens into bare rock.
lichen spores carried on the wind settle on the rock and creat soil. linchens add nutrients to the soil as they die and decay.
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

pain receptors
thermoreceptors
proprioreceptors
mechanoreceptors
EXPLAIN
Answer:
Mechanoreceptors
Explanation:
If Propriorceptors are for sensing light, thermoreceptors are for decenting temperatures, and pain receptors are for detecting injury, then mechanoreceptors would be used for sensing touch, and in this case you are touching the iphone screen, so mechanoreceptors is the correct answer.

~Read the article excerpt then respond to the question below.~
"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?
Explain your thinking.
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. The ultimate norm for any medicine (human made or natural) is their non-toxicity, effectiveness, specificity, stability and potency.

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.

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.

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.
