A cell sends messages to itself via autocrine signalling. So the correct option is B.

The type of cell signalling in which a cell releases a signal from itself and then that signal binds to the same cell. The chemical signal that is released from the cells is known as autocrine agents or autocrine signals.

Autocrine agents are usually hormones or chemical signals. They act as ligands and then bind to the receptors that are present in the cells that have produced them. Such kind of receptors is known as autocrine receptors.

When the autocrine agents bind to the autocrine receptors, autocrine stimulation occurs. This is a chemical reaction that is induced within for the necessary functions that need to happen.

This autocrine signalling is observed at early developmental stages and organ formation happens. These are for pain sensation & inflammation regulation.

Cells infected with viruses also produce autocrine signalling. Autocrine signalling also has an important function in cellular homeostasis. For example, progesterone is important as an autocrine signal molecule in breast cancer.

Therefore, the correct option is B.

Explanation:

Should scientists even try to answer questions about the purpose of the universe? Most researchers assume that science and religion are completely separate fields—or, in the phrase coined by evolutionary biologist Stephen Jay Gould, “nonoverlapping magisteria.” But as physicists investigate the most fundamental characteristics of nature, they’re tackling issues that have long been the province of philosophers and theologians: Is the universe infinite and eternal? Why does it seem to follow mathematical laws, and are those laws inevitable? And, perhaps most important, why does the universe exist? Why is there something instead of nothing?

Medieval philosopher Thomas Aquinas posed similar questions in his 13th-century book Summa Theologica, which presented several arguments for God’s existence. He observed that all worldly objects can change from potential to actuality—an ice cube can melt, a child can grow—but the cause of that change must be something besides that object (warm air melts the ice cube, food nourishes the child). The history of the universe can thus be seen as an endless chain of changes, but Aquinas argued that there must be some transcendent entity that initiated the chain, something that is itself unchanging and that already possesses all of the properties that worldly objects can come to possess. He also claimed that this entity must be eternal; because it is the root of all causes, nothing else could’ve caused it. And unlike all worldly objects, the transcendent entity is necessary—it must exist.

Aquinas defined that entity as God. This reasoning came to be known as the cosmological argument, and many philosophers elaborated on it. In the 18th century, German philosopher Gottfried Leibniz described God as “as “a necessary being which has its reason for existence in itself.” It’s interesting to note that Leibniz was also a mathematician and physicist; he invented differential and integral calculus at about the same time that Isaac Newton did. (They developed the math independently.) Both Leibniz and Newton considered themselves natural philosophers, and they freely jumped back and forth between science and theology.

By the 20th century, most scientists no longer devised proofs of God’s existence, but the connection between physics and faith hadn’t been entirely severed. Einstein, who frequently spoke about religion, didn’t believe in a personal God who influences history or human behavior, but he wasn’t an atheist either. He preferred to call himself agnostic, although he sometimes leaned toward the pantheism of Jewish-Dutch philosopher Baruch Spinoza, who proclaimed, in the 17th century, that God is identical with nature.

Likewise, Einstein compared the human race to a small child in a library full of books written in unfamiliar languages: “The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend, but only dimly suspects. That, it seems to me, is the attitude of the human mind, even the greatest and most cultured, toward God. We see a universe marvelously arranged, obeying certain laws, but we understand the laws only dimly.”

Einstein often invoked God when he talked about physics. In 1919, after British scientists confirmed Einstein’s general theory of relativity by detecting the bending of starlight around the sun, he was asked how he would’ve reacted if the researchers hadn’t found the supporting evidence. “Then I would have felt sorry for the dear Lord,” Einstein said. “The theory is correct.” His attitude was a strange mix of humility and arrogance. He was clearly awed by the laws of physics and grateful that they were mathematically decipherable. (“The eternal mystery of the world is its comprehensibility,” he said. “The fact that it is comprehensible is a miracle.”)

But during the 1920s and 1930s, hefiercely resisted the emerging field of quantum mechanics because it clashed with his firm belief that the universe is deterministic—that is, physical actions always have predictable effects. Einstein famously criticized the indeterminacy of quantum theory by saying, God “does not play dice” with the universe. (Niels Bohr, the father of quantum mechanics, is said to have remarked, “Einstein, stop telling God what to do.”)

Although quantum theory is now the foundation of particle physics, many scientists still share Einstein’s discomfort with its implications. The theory has revealed aspects of nature that seem supernatural: the act of observing something can apparently alter its reality, and quantum entanglement can weave together distant pieces of spacetime. (Einstein derisively called it “spooky action at a distance.”) The laws of nature also put strict limits on what we can learn about the universe. We can’t peer inside black holes, for example, or view anything that lies beyond the distance that light has traveled since the start of the big bang.

Explanation:

Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.

Oxygen and glucose needs to be absorbed and waste products need to be removed for the proper functioning and maintenance of the body cells and systems.

Oxygen is an odor less and colourless gas that is needed by living organisms.

It is absorbed by living organisms because it serves as a source of fuel.

Glucose is a type of carbohydrate called monosaccharide which is gotten from food.

It is assimilated or absorbed into the body through the hormone insulin and serves as a source of energy.

Waste products of metabolism is removed from the body through the process of excretion. A typical example is the carbondioxide.

If Waste products are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

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.

“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.”

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 (“liking” water) in the dark but become hydrophobic (“disliking” water) 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.

The Prokaryotae are further divided into two subkingdoms. These are called the Eubacteriobonta (which contains the so-called Eubacteria) and the Archaebacteriobonta (which contains the so-called Archaebacteria). This split arose from the research of Carl Woese.

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.

Explanation:

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.
