Answer:
Well, If the dye is found outside of the system then it would mean that there was an opening somewhere making it an open system. If there was not dye found in the surrounding areas then that means its a closed system.
Note: Glad I could help!
If the dye is found outside of the system then it would mean that there was an opening somewhere making it an open system. If there was not dye found in the surrounding areas then that means its a closed system.
What are the differences between open and closed system?An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
One might describe a thermos as a closed system because it only allows energy to enter and leave it; but not matter (because it won't spill).
Open systems in thermodynamics allow matter as well as energy to enter and leave. For example this coffee cup is an open system when compared to the thermos.

The following chemical equation shows the reaction of cellular respiration.
C6H12O6+ __O2 —> 6CO2 + 6H2O + Energy (chemical)
Part A Balance the above reaction by writing in the correct coefficient.
Answer:
C6H12O6+ 6O2 → 6CO2 + 6H2O + Energy (chemical)
Explanation:
Given that,
→ C6H12O6+ __O2 → 6CO2 + 6H2O + Energy (chemical)
Now we have to balance the equation,
→ C6H12O6+ 6O2 → 6CO2 + 6H2O + Energy (chemical)
Hence, this is the balanced equation.

Which of the following is an example of an antigen that might be recognized by the immune system of an individual?
A. a fat molecule
B. saline solution
C. oxygen molecule
D. a viral protein
An example of an antigen that might be recognized by the immune system of an individual is a viral protein. That is option D.
What is an Antigen?An antigen is a substance that is capable of being recognised as non-self by the immune system of an individual which can lead to an immune response.
The fat molecules, saline solution and oxygen molecule are not antigens because they can't be recognized as non-self.
Therefore, an example of an antigen that might be recognized by the immune system of an individual is a viral protein.

Answer:
The answer is Memory trace.
Explanation:
a hypothetical permanent change in the nervous system brought about by memorizing something; an engram.The term that is used to describe the biochemical representation of the experiences within the brain, which are known to deteriorate over time, is "memory," which is stored in the neurons.
Memory refers to the brain's ability to think, to remember after some time etc and more is the stronger connection among the neurons more is the memory power of the brain. Over time, memories can deteriorate due to several factors, such as interference, neurodegenerative disorders, etc. Apart from this, many other things, such as the weakening of synaptic connections, the loss of neurons, etc., also lead to memory loss.

Osmosis, simple diffusion, and
facilitated diffusion are all examples
of.....
A. passive transport
B. active transport
C. energy assisted transport
Answer:
A
Explanation:
It's passive transport because it does not require energy, i.e. you don't need to invest ATP to make it happen. Osmosis is the movement of water from area of higher solute concentration to area of lower solute concentration. It happens via channel proteins called aquaporines. Simple diffusion is when gases like O2 or CO2 difuse through the cell membrane. Again, they go from area of higher concentration to area of lower concentration. Facilitated difusion is how large and polar molecules go in and out of the cell. This happens via transmembrane proteins down the concentration gradient (from higher to lower concentration).
What part of the visible spectrum is absorbed by the primary pigments of eukaryotic photosynthesis
Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll band the carotenoids.
What do Primary pigments absorb?There are three primary pigments. Each pigment is designed to absorb a single primary color of light. Cyan pigments absorb red light and reflect blue and green light. Magenta pigments absorb green light and reflect red and blue light.
Thus, Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green.

In the past few years, several bills that deal with noise pollution have been introduced in Congress. Several lawmakers want to make stricter laws at the national level to restrict noise pollution.
Compose a letter to one of your state's representatives about noise pollution. In your letter, persuade your lawmaker that noise pollution should be controlled more strictly and be sure to address the following points:
explain what noise pollution is and where it comes from,
explain how noise pollution can harm people,
explain how noise pollution can harm wildlife, and
explain how you think national noise pollution laws could work.
Answer:
1.Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems.
2.Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is Noise Induced Hearing Loss (NIHL). Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress. These health problems can affect all age groups, especially children
3.Studies have shown that loud noise can cause caterpillars' hearts to beat faster and bluebirds to have fewer chicks. Noise pollution makes it difficult for animals to use sound for navigation, finding food, mating, and avoiding predators, affecting many animals' ability to survive
4.We can Reduce Noise pollution by turning off appliances when not in use, use of earplugs, lowering the volume, planting more trees, regular maintenance of vehicles and machines. By controlling noise we can control negative health effects that noise pollution has on everyone.
