Cellular Respiration and Photosynthesis. Photosynthesis is the process of when plants use sunlight to make foods from carbon dioxide and water, to later on make oxygen. Cellular respiration is the process through which cells convert sugars into energy.

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.

Hope this helps! :)

I recommend you search this same question, and you'll find the answer. If I were to answer your question theoretically, I would copy and paste the answer I searched, but but use some of my own words.

Answer:

I think the answer should be meteorology

Meteorology is the word that describes the scientific study of weather and the atmosphere.

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.

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: False

Explanation: Prokaryotes can only be unicellular. Eukaryotes are both. So false.

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.

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...

Answer:

A. 75% B. 25%

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:

the only option that is correct is the third

Explanation:

the second isn’t correct because they contain strands of thousands of genes. The first isn’t correct because they are both passed on. The last one isn’t correct because they are both made up of DNA

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

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.

Explanation:

Answer:

DNA -> RNA is transcription

RNA > Protein is translation

The process illustrated in the figure above 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.

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.
