Answer:
Proton proton chain reaction involves the fusion of two hydrogen atoms.
Explanation:
Two protons combine together to form a deuterium nucleus, a neutrino and a positron.
This deuterium will then combine with another hydrogen to form a helium isotope with mass number three and gamma rays.
Now two helium isotopes combine to form a helium 4 nucleus and two protons.
These two protons will once again initiate another proton proton cycle.
These are called thermonuclear fusion reactions. They are responsible for the heat and light that are received from sun .
Proton proton cycle happens in all stars primarily.

Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
this is for the Absorption and Radiation by Land and Water
Answer:
What I recommend doing to writing the perfect lab report is to think of it as a story. Begin stating the facts and such things. Then include your preliminary observations. End it with describing the results and explining why they are important. If you want a good grade, I recommend also tying it all back to the lesson your teacher was teaching you to begin with. You dont have to be a genius to write an amazing report, just state things from your observations and the lesson.

Two systems that work very closely together are our cardiovascular and respiratory systems. The cardiovascular system includes your heart and blood vessels , which function to remove deoxygenated blood from and return oxygenated blood thoughout your body. The heart then sends the oxygenated blood out to the body .
A good example is pulmonary system and the circulatory system .

describe an experiment (using 3-5 complete sentences) that you could conduct to test whether or not humans can see in complete darkness. Make sure to include your independent and dependent variables.
Answer:
An experiment that I could conduct to test whether or not humans can see in complete darkness is by simply going into a place where I know it would be pitch black if I turned off the lights. Such as an basement or closet. I could have a friend or family member place an object close to me in the same room. Once the lights have been shut off I could easily try and find it. I have tried this experiment using a friend and myself. I could find the object just by trying to use things near me to guide myself and eventually found it. My friend on the other thought that they didn't need to use any senses to find the object but failed sadly. I say that my way of working my way to the object in the dark was most helpful because if you are familiar with your surroundings it could make things a lot easier. If you try not to use senses to help yourself in the dark things could get dangerous. You could either run into something or get hurt or end up grabbing the wrong thing.

I need a description of how the hurricanes forms/occurs
Answer:
Explanation:Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. ... If there is enough warm water, the cycle will continue and the storm clouds and wind speeds will grow causing a hurricane to form.

A student is constructing an explanation of the cycling of matter in and out of a plant during photosynthesis. Which statement would be most useful for the student to include? A.
Photosynthesis uses carbon dioxide and water, and releases oxygen.
B.
Photosynthesis uses oxygen and carbon dioxide, and releases water.
C.
Photosynthesis uses water, and releases carbon dioxide and oxygen.
D.
Photosynthesis uses oxygen, and releases carbon dioxide and water.
The process by which green plants and some other organisms use sunshine to create meals from carbon dioxide and water is called photosynthesis. Therefore, option (A) is correct.
What is photosynthesis?Photosynthesis is the process by which green plants and some other species use sunlight to create food from carbon dioxide and water. Other organisms may also participate in this process. Chlorophyll, a green pigment, is typically involved in the process of photosynthesis, which results in the production of oxygen as a byproduct in plants.
Photosynthesis takes place in the chloroplast, a specialized intracellular organelle found in plants and algae, which emerged considerably later. During the day, photosynthesis is carried out by chloroplasts. The photosynthetic cells use NADPH and ATP, the direct results of photosynthesis, to make a variety of chemical compounds.

Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory? A) It was not published until his death. B) It was not understood by scientific world. C) It lacked sufficient evidence and explanation. D) It lacked practical examples in supporting theory.
Answer:
B
Explanation:
The answer is B because the scientific community didn't see or have any practical evidence to show that Copernicus was right so they rejected the heliocentric theory.

Deserts typically have average daytime temperatures of around 100°F, while the average daytime temperature in tropical
rain forests is around 85°F. However, the average monthly temperatures in the desert are lower than the average
monthly temperatures in a rain forest. Explain the reason for this difference.
Answer:e
Explanation:it its different because when a desert ends up cooling down than you have to deal with cold temperatures sorry if i spelled that wrong also rainforest keep that heat in because of the trees so the desert doesn"t have any trees not enough to keep the heat in so the heat gets out and the temperatures end up cooling down hence why the rainforest has a higher temp.
What happens if neither plate goes down towards the mantle?
Answer:
please give me brainlist and follow
Explanation:
This would cause mantle material to rise in its place, pushing up the crust and forming isolated mountain ranges and associated basins. This activity would cause minor earthquakes and maybe even additional pockets of volcanism.
Answer:
Without plate tectonics, Earth would not have its diverse geography, which provides a wide range of habitats. Plate tectonics is also responsible for hydrothermal vents on the ocean floor.
