Ways to help our environment- please make it specific and explaining what to do and how to do it
Answer:
Some ways to help out society is to do things that benefit the world such as let's say community service. To be more specific community service is when everyday citizens of the society decide to do voluntary work in order to help people and or the environment. Some examples could be walking kids home from school, picking up trash on the ground, and fostering a shelter animal.You can do this by gathering people who agree with helping the earth and trying to make it a better place or even starting off little such as giving nice stuff that you don't need or use to the people who do need it such as the homeless shelter...

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.
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.

Explanation:
which strand of the DNA molecule A or B was used to produce the messenger RNA?
Answer:
Strand A
Explanation:
Why is it strand A when it looks exactly like strand B? During transcription, a strand of RNA is made that compliments the DNA. Meaning they don't exactly match but they're the partner nucleic acid. These are the instructions that tell what protein to make.
In humans, a widow’s peak hairline is determined by the dominant allele (W), and a straight hairline is determined by the recessive allele (w). If a male is heterozygous for a widow's peak and a female has a straight hairline, what is the probability they will have a child with a straight hairline?

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.

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.

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.

Which of the following regions does not experience seasons: Tropic of Cancer, Equator, or Artic?
Write an explanation below using observations from the simulator found at the following link, to justify your answer.
https://www.khanacademy.org/science/cosmology-and-astronomy/earth-history-topic/earth-title-topic/pi/season-simulator
Answer:
Equator and Arctic because equator is too hot and arctic is too cold. In equator the rays of the sun fall directly all over the year and this is why the [people living there experience a harsh hot weather and high temperatures. On the other hand people living in the Arctic region experience extreme cold because very little sunlight reaches there. Temperatures are freezing cold all over the year.
plz mark me as brainliest.
Answer:
The arctic does not suffer any seasons as it is furthest from the equator and therefore is covered in ice snow and rarely sees sunlight. Therefore the arctic does not have summer autumn or spring. The arctic is so cold that not many trees can survive and the ones that do are usually chopped down to build houses for the people who live there. The arctic is home to one of the worlds largest seed banks that is there in case of a really bad emergency where the farmers crops in another country are not growing.

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
