Answer:
heat from the sun
Explanation:
There are several ways to model a compound. One type of model is shown.
4 C's are connected in a line by 3 black lines. The C on the left has 3 H's attached to it each by a black line. The next C has 1 H attached by a black line and 1 O attached by 2 black lines. The next C has 2 H's attached to it by 1 black line each. The last C has 2 H's attached to it by 1 black line each and 1 O attached by a single black line. That O has an H attached to it by 1 black line.
What is the chemical formula for the molecule represented by the model?
A. CHO
B. C4H9O2
C. C4H8O
D. C3H8O2
Answer : The chemical formula for the molecule is C4H902
Explanation :
Molecular formula : It is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.
In the structural formula, the lines are used between the atoms.
As per given information of compound we conclude that, there are 4 carbon atoms, 9 hydrogen atoms and 2 oxygen atoms.
Thus, the chemical formula for the given molecule will be, C4H902

How does this model explain the causes of seasonal changes in the Northern Hemisphere?
In your response include the following information:
- Identify which stage (number) of the model represents summer and which represents winter in the Northern Hemisphere.
- Describe how Earth's tilt on its axis affects the intensity of solar energy during the summer versus winter months.
- Explain how the orientation of Earth and its positions in its orbit around the Sun causes the change in seasons in the Northern Hemisphere.
Which of these does the sun provide in large amounts?
1. energy
2. oxygen
3. glucose
4. Carbon dioxide
Answer: 1. Energy
Explanation: The sun provides energy.
It isn't oxygen because that is what get's produced along with glucose (sugar) in the process of photosynthesis. In this process, green plants use sunlight, water, carbon dioxide to create glucose and oxygen. So, it can't be oxygen, glucose or carbon dioxide.

The atmosphere is divided into spherical layers based upon the A. amount of precipitation contained within each layer of the atmosphere..
B. concentration of oxygen contained within each layer of the atmosphere.
C. variation in the concentration and amount of ozone contained within each layer of the atmosphere.
D. temperature changes from variations in absorption of solar energy within each layer of the atmosphere.
In an ecosystem, the atmosphere is divided into spherical layers based upon the concentration of oxygen contained within each layer of the atmosphere.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Define the following Atmosphere Geosphere Hydrosphere Geocentric Heliocentric Hypothesis theory
Answer: Howdy, hope this helps!
Atmosphere - The layer of gases surrounding the earth
Geosphere - Any of the spherical regions of matter that make up the earth and it's atmosphere, as the lithosphere and hydrosphere.
Geocentric - Measured from or considered in relation to the center of the earth.
Heliocentric - Measured from or considered in relation to the center of the sun.
(Not quite sure what they require on the definition of Hypothesis theory, I'll try my best here)
Hypothesis theory - We know that a hypothesis is a tentative explanation or prediction, and we also know that a Theory is a substantiated explanation for an occurrence.

Using scientific terms and knowledge, explain what might happen if you were to place an unopened can of Monster Energy drink in the stove, turn the stove to 450 degrees and leave it in there for a long time. Be sure to explain why you predict these things would occur.
SOMEONE PLS HELP
Answer:
The heat could put stress on the metabolism, which could lead to dehydration. Energy drinks are designed to be stimulants and can give people a little edge when playing sports. They can also be dangerous because stimulants can increase body temperature and pose a hypothermia threat. But if you leav it in the stove then it the liquid would eventually evaporate and the sugar would be left. But, that also would leave the rest of the sugar which would look like tar or slime.

How does a prism separate white light into various colors and why are the colors always in the same order?
I believe that there is a spectrum of light in which we can see. When the white light enters the prism, it is refracted and bends into the visible light we can see of the spectrum.
The reason we always see the spectrum in the same order is because it is how our brain perceives it. Animals could see it in a different order, etc. This is just how the human brain sees it.

What’s your position about building roads in the rainforest? Write a paper that explains your position. Use facts from your research to support your position. How would humans and different parts of Earth be affected by the construction? Is there any argument against your position? You should write two paragraphs. One paragraph gives background about the problem, and the other tells your position and supports it. Your work should be free from spelling, punctuation, capitalization, and grammatical errors.
Humans and Animals will be affected differently in many ways. The construction of roads has to access logging, oil, and mining sites in the forest. These roads are funded by government and development agencies, some are financed by private companies or development interests.
For humans, it is somewhat better because the food products come from rainforests as well, such as bananas, citrus, cassava, avocado, cashews, Brazil nuts, vanilla, sugar, coffee, tea, and cocoa. Medicine also comes from the rainforest, some of the ingredients for medicine come from the plants. So do materials such as rubber, oil, gum, resins, and paper. However, if we grew more farms and gardens we would be able to provide food from those gardens and farms, it will take more work, but it will be worth it. Using the products in the rainforest, it's a bad thing and a good thing. The food and materials help survive, yet it could kill the forest and places for animals to live in.
There are many roads that are being built or upgraded, it's a good thing because it can be a lot safer for us, humans, to drive in. But again, they won't be able to fix all the roads, and adding roads in the rainforest would be a waste of time and just kill the animals and the forest itself. It can help the people in the forest much more, but as we see, the people also survive that way. Road construction in the forest can cause impede streams, increase forest flooding, and drastically increase soil erosion. If that happened fish can die out and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
If we did keep the roads paved at all times, it can save money and energy and reduces greenhouse gas emissions, more than offsetting pollution generated during road construction, according to a new study. Many parts of the world are increasingly the result of political pressure from corporate interests, namely loggers, mining companies, oil and gas developers, and industrial agricultural firms, rather than government-backed poverty alleviation and development efforts.
The deforestation of rainforests can be a big and devastating effect on our world. It can lead to many animals getting extinct, which is happening as of today. It also decreases the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. It can also have a huge effect on our climate, and climate can destroy animals, like in the Arctic.
