Using the diagram above, answer the following questions:
True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
1. I belive number 1 is false because as shown in the picture, it is a chemical energy going out of the factory but I don't think it is going into a mechanicalm energy. This is the definiton of mechanical energy. "Mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system."
2. I belive this is true because yes, solar energy is being transfered to a chemical energy. The sun, which is the solar energy, is being transferred in phtosynthesis.
3. I belive arrow C is a release of carbon dioxide because from the factory it is releasing to the air causing climate change.
4. I belive arrow F and E because it is showing the carbonation cycle.
5. Belive B and D because it blances the mass and energy.

Which of the following is true when comparing societal laws to scientific laws?
Scientific laws are valid all over the world, while societal laws differ from region to region.
Both scientific laws and societal laws are accepted after qualified professionals vote on them.
Both scientific laws and societal laws are accompanied by severe legal consequences for breaking them.
Societal laws are based on numerous experiments, while scientific laws are accepted only by the votes of well-known scientists.
Answer:
Both scientific laws and social laws are accepted after qualified professionals vote on them.
Both scientific laws and societal laws are accepted after qualified professionals vote on them. The correct option is B.
What are societal laws?Societal laws are rooted in the choices and conduct imposed by society or government.
Laws protect our general safety and our rights as citizens from abuses committed by other people, organizations, and the government itself.
We have laws in place to help ensure our general safety. Laws governing food safety are available at the local, state, and national levels.
A scientific law is a fundamental principle, generalization, regularity, or rule that applies universally under specific conditions.
To explain and predict individual occurrences or instances, laws are developed from facts or mathematically.
After qualified professionals vote on them, both scientific and societal laws are accepted.
Thus, the correct option is B.

A group of scientists are studying a disease which is caused by contaminated food. The chemicals in this food cause harm to the body through interactions with the digestive and the immune systems. Which of the following are the scientists most likely to find in their research?
(A) When the contaminated food is eaten, the immune system prevents the harmful chemicals from entering the digestive system.
(B) The harmful chemicals enter the immune system through a break in the skin. The chemicals are then passed to the digestive system by the cardiovascular system.
(C) The harmful chemicals enter the digestive system through contaminated foods. Once in the body, the chemicals reduce the ability of the immune system to react to pathogens.
(D) The immune system transforms the harmful chemicals in the contaminated food into a different form of chemical, which is then broken down and absorbed by the digestive system.

A proper balance of oxygen and carbon dioxide must be maintained in the human body to survive. Which of the following body systems is responsible for taking in and releasing these gases to ensure homeostasis?
A. Digestive System
B. Excretory System
C. Circulatory System
D. Respiratory System
Answer:
D. Respiratory System
Explanation:
The system acts to reverse the direction of change. Since this tends to keep things constant, it allows the maintenance of homeostatic balance. For instance, when the concentration of carbon dioxide in the human body increases, the lungs are signaled to increase their activity and exhale more carbon dioxide, (your breathing rate increases).
The system that is responsible for taking in and releasing these gases to ensure homeostasis is respiratory system. The correct option is D.
What is respiratory system?The respiratory system soaks up oxygen from the environment humans breathe as well as remove carbon dioxide.
The lungs are basically the primary organs of the respiratory system. The nose, trachea, as well as breathing muscles are respiratory organs too.
The respiratory system encompasses the muscles that power up the lungs.
These components usually work altogether to transport oxygen throughout the body and remove waste gases such as carbon dioxide.
The lungs are the primary organs of the respiratory system. The nose, trachea, and breathing muscles such as the diaphragm and intercostal muscles are also respiratory organs.
Thus, the correct option is D.

Describe the flow of energy in a marine food web.
Include at least 5 organisms in your answer.
1. The energy flow takes place via food chain and food web. During the process of energy flow in the ecosystem, plants being the producers absorb sunlight with the help of the chloroplasts and a part of it is transformed into chemical energy n in the process of photosynthesis.
2. This means that they form a kind of cycle. The extinction of one organism can cause a ripple effect that impacts all of the species involved in that food web. This means that one organism would destabilize the whole food web. The extinction of a keystone specie might force all the organisms to adapt, because this specie is one whose presence and activities strongly affect other species. In other cases the ecosystem is the one that adapts to the lack of the organism. The extinction of species with a strong interaction in the food web occur more often that the others that do not have much interaction. In some cases the food web would be affected because some animals would not have a source of food, therefore they would not have energy. That way they would have to find another way to get the food or in extreme cases they could also get extinct. An example is like the one in the picture, if the phytoplankton dies or decreases its number, its consumers would decrease their number as well, eventually the decrease of a very tiny organism would end up to the extinction of a large organism such as the killer whale or elephant seal.
