Answer:
ummm not good so I got this from my teachers textbook
Explanation:
Most of the Universe consists of matter and energy. Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of atom, for example Carbon atoms make up diamond, and also graphite. Pure (24K) gold is composed of only one type of atom, gold atoms. Atoms are the smallest particle into which an element can be divided. The ancient Greek philosophers developed the concept of the atom, although they considered it the fundamental particle that could not be broken down. Since the work of Enrico Fermi and his colleagues, we now know that the atom is divisible, often releasing tremendous energies as in nuclear explosions or (in a controlled fashion in) thermonuclear power plants.The atomic number is the number of protons an atom has. It is characteristic and unique for each element. The atomic mass (also referred to as the atomic weight) is the number of protons and neutrons in an atom. Atoms of an element that have differing numbers of neutrons (but a constant atomic number) are termed isotopes. Isotopes, shown in Figure 1 and Figure 2, can be used to determine the diet of ancient peoples by determining proportions of isotopes in mummified or fossilized human tissues. Biochemical pathways can be deciphered by using isotopic tracers. The age of fossils and artifacts can be determined by using radioactive isotopes, either directly on the fossil (if it is young enough) or on the rocks that surround the fossil (for older fossils like dinosaurs). Isotopes are also the source of radiation used in medical diagnostic and treatment procedures.

What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

The diagram shows changes of state between solid, liquid, and gas. The atoms of a substance gain energy during a change of state. Before the change, the atoms are close together and cannot slide past one another. After the change, the substance can fill its container.
A diagram has a triangle at center with gas on top, liquid on bottom right, solid on bottom left. An arrow from gas to liquid is labeled O, and an arrow from liquid to gas is labeled N. An arrow from solid to liquid is labeled P, and an arrow from liquid to solid is labeled Q. An arrow from solid to gas is labeled L, and an arrow from gas to solid is labeled M.
Which arrow represents the change of state described above?
L
M
N
O
Answers
Answer:
L, solid to gas
Explanation:
Both gas and liquid have atoms that can slide past each other, where as, solids have atoms that vibrate in place. The paragraph states that, "Before the change, the atoms are close together and cannot slide past one another.." meaning that the atoms in the substance will be able to slide past each other after the change, and that the substance was a solid before the change. Look back in that text again and you'll find that it also says, "After the change, the substance can fill its container.." meaning that the substance can move freely within its containment system, and that the substance is gas. There was energy added to the electrons in this substance.. there are a few ways of doing that, but the process in which this situation does it is called "sublimation." Sublimation is a phase change where a solid has energy added to it and skips straight into the gas phase with no liquid phase in between. The arrow in the diagram labelled "L" is pointing from solid to gas, making this the answer.

L

As an analogy of a circuit with resistance, think of an obstacle race . Which parts of a circuit do the obstacles represent? which part of the circuit do the people respresent?
Answers
In an analogy of a circuit with a resistance to an obstacle race, we can consider various elements of the race as representative of different components of the circuit.Obstacles, Track or Route, Participants, Start and Finish Line.
Obstacles: The obstacles in the race represent the resistors in a circuit. Just as resistors impede the flow of current in a circuit, obstacles in the race create hurdles that slow down the participants. The difficulty or magnitude of the obstacles can be equated to the resistance value of the resistors in a circuit.
Track or Route: The race track or route itself can be seen as the conductive path in a circuit. It provides a pathway for the participants to move and complete the race. Similarly, the conductive path in a circuit allows the flow of current from the power source to the load.
Participants: The people participating in the race represent the flow of electrons in a circuit. Just as the participants move through the obstacles in the race, electrons move through the resistors in a circuit. The rate at which participants complete the race can be compared to the current flowing through the circuit.
Start and Finish Line: The start and finish line of the race correspond to the terminals of a circuit. The start line represents the positive terminal, where the participants begin their journey, and the finish line represents the negative terminal, where the race concludes.

Answer: As an analogy of a circuit with resistance, the obstacles in an obstacle race represent the resistance in a circuit. The parts of the circuit that the obstacles represent are the resistors. The people in the obstacle race represent the current in a circuit. The current is the flow of charged particles (such as electrons) in a circuit. In an obstacle race, the people are moving through the obstacles, just as the charged particles are moving through the resistors in a circuit. The obstacles slow down the people, just as the resistors slow down the flow of charged particles in a circuit.

The average woodpecker smashes its beak against a hard surface more than 10,000 times a day. Any human who jolted their head like this would likely end up with a concussion. This traumatic brain injury is caused by a blow to the skull. So why doesn’t the constant hammering turn woodpeckers’ brains into mush? For years, it was assumed that woodpeckers had some kind of cushioning in their heads to protect their brains during pecking. Many scientists suggested that spongy bone in the birds’ skulls absorbed and lessened the shock of each impact (see Myth Buster: Hard Headed). This idea was repeated in scientific articles, textbooks, and informative plaques at zoos. Even though the concept “is often presented like a clear-cut fact, there haven’t been any real tests to prove it,” says Sam Van Wassenbergh. He’s a biologist who studies biomechanics, or how living things move, at the University of Antwerp in Belgium.SHOCK ABSORBER: Van Wassenbergh uses a spring-loaded hammer to show why a shock-absorbing skull would make a woodpecker less efficient at pecking. When you think about it, says Van Wassenbergh, the shock-absorbing skull idea doesn’t make much sense. Woodpecker drills into the wood in search of insects to eat. When the bird’s head accelerates forward, the movement generates kinetic energy. This energy of motion is transferred to the tree when the bird slams its beak against the trunk. If a woodpecker’s skull had to cushion, it would absorb some of this energy and decrease the force of the peck. Why would a bird that survives by pecking evolve to do it less effectively? Van Wassenbergh and his team decided to see what was really going on. First, the researchers recorded videos of woodpeckers’ heads in motion. To capture this rapid movement, the scientists needed special high-speed cameras. Each peck lasts only a fraction of a second! Van Wassenbergh’s team recorded videos of six woodpeckers from three species and analyzed the footage. The researchers used a computer to track three points on each bird’s head: one on the skull and two on the beak. The scientists hypothesized that if the birds’ skulls had shock absorbers, the footage would show a “squishing” of the space between the skull and beak—like when a spring compresses. But that didn’t happen. Instead, the birds’ heads moved as one stiff unit, like a hammer. Next, the team wanted to demonstrate why this adaptation would be helpful to the birds. Using computer models, the scientists simulated woodpecker skulls with and without shock absorbers. Then the researchers compared the force of the pecks. “The pecking performance was greatly reduced in the skull with a shock absorber,” says Maja Mielke, a biologist who worked on the study. With shock absorbers, says Mielke, “the poor birds would need to pound even harder to reach the same results.” For a woodpecker, having a shock-absorbing skull would simply be a waste of energy. Science World originally published this diagram in our May 10, 2021, issue. It was based on scientists’ beliefs about woodpecker anatomy at the time. Here it is again—updated based on new research. MYTH: The skull is made of spongy bone that cushions and protects the brain from impactBUSTED! The skull is hard enough to protect the bird from injury, but it doesn’t cushion The eyes have a special membrane that protects them from flying splinters and wood dust.MYTH: Neck muscles are strong and stiff enough to absorb the shock of each peck BUSTED! Stiff neck muscles do not absorb shock—in fact, they help increase the force of each peck.MYTH: The tongue wraps completely around the outside of the skull, providing an additional level of cushioning, and can extend to probe for food inside holes made by the birdBUSTED! The tongue does not provide any observable cushioning. The beak is connected to the skull with thick bone that prevents jolts and vibrations. NEW RESEARCH SHOWS: The woodpecker’s brain is small, which helps prevent concussions that might occur in a larger animal. If woodpeckers’ skulls don’t absorb shock, then why doesn’t constant pecking damage the birds’ brains? To answer this question, the researchers calculated how harmful the blows from pecking actually are. It turns out the hits aren’t that dangerous because the birds’ brains are so small. “Small masses can tolerate stronger impact forces without being damaged,” says Mielke.

"The average woodpecker smashes its beak against a hard surface more than 10,000 times a day."
"This traumatic brain injury is caused by a blow to the skull."
"So why doesn’t the constant hammering turn woodpeckers’ brains into mush?"
The conclusion of the story is that woodpeckers don't get brain damage from pecking because their brains are small, which allows them to handle the force of the pecks.
"Small masses can tolerate stronger impact forces without being damaged,"
"The hits aren’t that dangerous because the birds’ brains are so small."

hi:) anyone able to explain why it’s easier to lift something on moon compared to earth? thanks:)
Answers
Because the moon has much less mass than the Earth has. This makes the gravitational forces between the moon and any object much less than the forces between the Earth and the same object, when the object is the same distance from the center of the moon or the Earth.
To talk about an actual number, we usually talk about being on the surface of the Earth or the moon:
A person or object on the surface of the moon weighs about 17% as much as he/it weighs on the surface of Earth. That's about one-sixth as much. So naturally, it's easier to lift something on the moon than it is to lift the same thing on Earth, because when it's on Earth, it's about six times as heavy.

Answers
Answer:
There are several ways to describe and compare materials based on odor and taste. This includes adjectives that describe the object/materials,
Explanation:
You can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.
How many types of objects are there based on taste?There are five types of objects or materials that are based on the attribute of taste. This is because of taste receptors in the mouth sense the five taste modalities. It incudes sweetness, sourness, saltiness, bitterness, and savoriness (also known as savory or umami).
Scientists have classified odors into 10 basic categories: fragrant, woody/resinous, minty/peppermint, sweet, chemical, popcorn, lemon, fruity (non-citrus), pungent and decayed.
Both taste and odor of the materials and objects are represented with the help of a part of speech known as adjectives. Adjectives can be used to describe the qualities of someone or something independently or in comparison to something else, such as taste, color, odor, etc.
Therefore, you can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.
