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.”

describes lipids in water
Answer:
Ok
Explanation:
Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Hope this helped

The louse Cymothoa exigua lives inside the mouth of certain fish. It attaches to the fish’s tongue, strangling it until it falls out. Once the tongue falls out, the louse functionally replaces it. Generally, this is thought of as a parasitic relationship.
What criteria would need to be met for this relationship to be considered parasitic? Is it possible that this relationship could be an example of mutualism or commensalism? Use what you have learned to classify this relationship and explain your reasoning.
Answer:
A parasitic relationship is the one in which parasite or the organism that feeds upon the host benefits while the host organism is negatively affected.
This relationship cannot be classified as mutualism or commensalism
To Understand the relationship between louse Cymothoa exigua and fishes we need to understand the following:
What is a parasitism?
A parasitic relationship occurs when one creature, the parasite, feeds on another organism, the host, causing injury and possibly death to the host. A parasite lowers the fitness of its host while increasing its own, usually by getting food and shelter.What is a mutualism?
Mutualism is a type of relationship in which both live organisms benefit equally and no one is harmed. Lichen is a mutualistic association between a fungus and algae, for example. ALgae provides food to fungus by photosynthesis and in return the fungus provides nutrients to algae.What is Commensalism?
commensalism is a relationship between members of two species in which one derives food or other benefits from the other without harming or benefiting the other.Orchids are a type of flowering plant that grows on tree trunks and branches. Orchids rely on the host plant's branches for sunlight and nourishment. on the other hand, they provide no benefit or harm to the host plants.Hence this relationship cannot be an example of either mutualisma and commensalism because the host fishes are harmed as their tongue falls out due to louse Cymothoa exigua and in return the parasite attaches itself to the host and feeds on them

Which type of carbohydrate is this?
A) Monosaccharide
B) Simple sugar
C) Complex carbohydrate
D) Disaccharide
Answer:
A
Explanation:
monosaccharide is derived from mono, meaning "one", and saccharide, meaning "sugar". The common monosaccharides are glucose, fructose, and galactose. Each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively. Although each sugar mainly exists as a cyclic compound, it is important to note that they are all in equilibrium to a small extent with their linear forms.
While galactose and glucose are composed of six-membered rings, fructose has only five carbon atoms bonded to each other in ring form.

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.

Which states would be the most likely to experience the next volcanic eruption AND earthquake in the United States? List at least 3 for each hazard and explain why they might happen there.
Answer:
AlaskaWashingtonHawaiiCaliforniaOregonExplanation:
Eruptions along the western edge of the United States have formed the Cascades volcanic mountain range. Also, they develop island chains, such as the Aleutians in Alaska, which makes Alaska a potential volcanic eruption place. A prominent example of an eruption along the Ring of Fire was the dramatic eruption of Mount Saint Helens in Washington in 1980, which makes Washington a potential volcanic eruption state. Deep beneath Hawaii, there is a fixed source of abundant rising magma, called a hot spot, making Hawaii likely to be a volcanic eruption state. In 2018, they added Salton Buttes to the 2018 assessment, which is a high threat of a volcanic eruption. In other words, California is likely to be a volcanic eruption state. Eleven of the eighteen very high threat volcanoes are in Oregon, and few other states, where explosive and often snow- and ice-covered volcanoes can project dangerous long distances to densely populated and highly advanced areas.

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.
