Light that Moves and Molds Gels
Pitt research team demonstrates gels that can be moved, controlled by light
PITTSBURGH—Some animals—like the octopus and cuttlefish—transform their shape based on environment, fending off attackers or threats in the wild. For decades, researchers have worked toward mimicking similar biological responses in non-living organisms, as it would have significant implications in the medical arena.
Now, researchers at the University of Pittsburgh have demonstrated such a biomimetic response using hydrogels—a material that constitutes most contact lenses and microfluidic or fluid-controlled technologies. Their study, published in Advanced Functional Materials, is the first to show that these gels can be both reconfigured and controlled by light, undergoing self-sustained motion—a uniquely biomimetic behavior.
Together with Olga Kuksenok, research associate professor in the Swanson School, Balazs experimented with a newer type of hydrogel containing spirobenzopyran molecules. Such materials had been previously shown to form distinct 2-D patterns on initially flat surfaces when introduced to varying displays of light and are hydrophilic in the dark but become hydrophobic under blue light illumination. Therefore, Balazs and Kuksenok anticipated that light could be a useful stimulus for tailoring the gel’s shape.
Using computer modeling, the Pitt team demonstrated that the gels “ran away” when exposed to the light, exhibiting direct, sustained motion. The team also factored in heat—combining the light and local variations in temperature to further control the samples’ motions. Controlling a material with light and temperature could be applicable, Balazs said, in terms of regulating the movement of a microscopic “conveyor belt” or “elevator” in a microfluidic device.

“Imagine an apartment with a particular arrangement of rooms all in one location,” said lead author Anna Balazs, Pitt Distinguished Professor of Chemical and Petroleum Engineering in the Swanson School of Engineering. “Now, consider the possibility of being able to shine a particular configuration of lights on this structure and thereby completely changing not only the entire layout, but also the location of the apartment. This is what we’ve demonstrated with hydrogels.”

Which fuel does the circulation of blood provide for cellular respiration and healing?
A. oxygen
B. protein
C. iron
D. ATP
Answer:
A. Oxygen
Explanation:
During cellular respiration the cell uses oxygen to break down sugar. When sugar breaks down it produces energy in which your body needs. Blood picks up oxygen and releses carbon dioxide into your lungs.
Hope this helps!!
The fuel responsible for the circulation of blood is oxygen.
It is very important for blood circulation to occur in the body. This is very essential so that all the cells and organisms are sufficiently funded with enough oxygen that is needed for them to function properly.
The fuel which enables proper amount of blood to spread/circulate round the body is oxygen. Oxygen is required during cellular respiration to break down sugar which then leads to the production of carbon dioxide and then releases energy for the body to work well.

How would the loss of predators contribute to deforestation in the
jungle?
Answer:
Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.

Ph, Acids and Bases Quick Check
Which statement best describes the difference between a substance with a pH of 3.0 and a substance with a pH of 6.0? (1 point)
O The substance with the higher pH has twice as many hydrogen ions per volume of water.
The substance with the lower pH has twice as many hydrogen ions per volume of water.
The substance with the higher pH has 1,000 times as many hydrogen ions per volume of water. O
O The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.
Answer: c
Explanation: 3.0 is 1,000 times as many ions
The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )
Given that the substance have pH ; 3 and 6
To prove the statement above we will make use of the pH formula
pH = -log(H⁺)
for substance with pH = 3
3 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻³
for substance with pH = 6
6 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻⁶
Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

Why would bacteria, plant and animal cells need to be different?
Answer:
Because each the cells would have different functions on different organisms.
Explanation:
Bacteria cells are usually prokaryotic which means that it is only composed of one cell. The single cell already has everything it needs so therefore, it isn't as complex as plant and animal cells.
Plants are autotrophs and produce their own food through photosynthesis. Plant cells would have a large vacuole, cell wall, chloroplasts, unlike animal cells.
Animal cells have all the cell organs that plant cells except a large vacuole, cell wall, and chloroplasts. Animal cells also have lysosomes in which plant cells don't.

Give the NUMERICAL value to the following question. If a car was traveling 25
m/s and then accelerated at a rate of 5 m/s/s for 3 s, then what was the final
velocity?
Answer:
Given,
initial velocity= 25m/s
acceleration= 5 m/s
time= 3 s
final velocity= ?
We know that,
acceleration= final velocity- initial velocity/ time
or, 5 = final velocity- 25 / 3
or, 5*3 = final velocity- 25
or, 15+ 25= final velocity
Therefore, final velocity is 40 m/s.

WHAT IS CIRCULATORY SYSTEM:
Circulatory system of the body comprises of the heart, blood and blood vessels. It functions majorly for the transportation or circulation of materials around the body. The heart is the organ of the circulatory system that disperses blood throughout the body. The blood is a carrier tissue that conveys nutrients, oxygen etc. throughout the body. The blood vessels are the channels through which blood moves in the body e.g veins, arteries etc. As stated in this question, oxygen is a major requirement for the heart to circulate oxygenated blood. Oxygen comes into the body via the lungs, which is a part of the respiratory system. This oxygen dissolves in blood and is transported to organs and cells by the circulatory system.Hence, oxygen from the respiratory system is delivered by the circulatory system.
