Answer:

14

Explanation:

if there is no number behind the element, it counts as one, but if there is, you do 1 times x(whatever the exponent is) and thats how many that one element counts for with atoms. then you just add them all up

Answer:

B. a meteor

Explanation:

Meteors, also known as shooting stars, are pieces of dust and debris from space that burn up in Earth's atmosphere, where they can create bright streaks across the night sky.

Answer:

two

Explanation:

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, 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: Hewo, there! your answer is Below

True would be the correct answer

Explanation:

Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.

Hope this helps you!!!

Have a great day!!!

Answer: True

Explanation: If something is more hot it's more likely to have less vegetation. If something is mild it's more likely to have vegetation and animals that live in that kind of weather same for rainy vegetation.

Answer: A and C

Explanation:

According to the electronic configuration, tin needs 4 more electrons to complete its outer shell.

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.

Answer:

C

Explanation:

each daughter received a different number of genes from each parent.

Answer:

a (top)

Explanation:

for B it shows different amount of genes

c is the same as B

d shows that they don't have similar genes

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.

Answer:

here we have UGA as the stop codon, the other codons are UAG & UAA. It's the portion of the instructions (our RNA) that tells us that the protein strand production stops there.

Answer:

Explanation:

a) Air pollution

b) It can cause climate change, respiratory problems etc

c)Winter. More energy is being used in the winter to heat  homes, offices, businesses etc.

Explanation:

heterozygous= having two different alleles of a particular gene (Ss)

     S     s

S  SS    Ss

s   sS    ss

A. SS, Ss, sS will have spikes on the tail => 3/4 = 75%

B. ss will have hammer tails => 1/4 = 25%

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

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.

Answer:

25%

Explanation:

not 100% sure but you should give this answer a shot

Answer:

It should be 25%, IF both parents are Ss.

Explanation:

I can't remember exactly what heterozygous means, but the definition i saw said it was one of each, so the recessive gene has a 25% chance

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...

Explanation:

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.
