Why is it more difficult to treat a malignant tumor than a benign tumor?
Answer:
Explanation:
Benign tumors also usually don't need treatment. If the tumor is impacting a nearby area or causing other problems, you may need surgery to remove it. Cancerous tumors almost always require treatment with surgical removal, radiation therapy, or chemotherapy.
1. List four ways in which the body uses energy.
Answer: Energy fuels your body's internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body's most important nutrient, helps facilitate the chemical reactions that produce energy from food.

what is the shortest wavelength?
Answer:
Violet or blue light has the shortest wavelength, making them more potent. Red or orange light have longer wavelengths, which makes them less potent.
I hope this helps :)
Explanation:
Answer:
Gamma Rays
Explanation:
Gamma rays have the shortest wavelength and the highest energy among the other waves in the electromagnetic spectrum. The wavelength of the gamma rays is less than 0.01 nanometers. Most of the gamma rays from space are blocked by the Earth's atmosphere.
How do homologous structures show
common ancestry?
A. They show us the genetic makeup of extinct organisms.
B. They show the situation that caused a species to branch
off from the original.
C. They show similarities between species and which
organism first developed the structure.
D. They are the structures that exist in the oldest living
member of an existing species.
According to the context, homologous structures show similarities between species and which organism first developed the structure.
What are homologous structures?They are structures that in different species fulfill similar functions, but have different embryonic origins, by virtue of their similarity, they suggest their connection with a common ancestor.
That is to say, it is the expression of the same genetic combination and that it is supposed to come from a common ancestor.
Therefore, we can conclude that according to the context, homologous structures show similarities between species and which organism first developed the structure.

Geoffrey records the heat transfer occurring in a sample of matter as being about one half as fast as he originally predicted. He concludes that the atomic structure of this matter must be more rigid and solid, as more rigid atomic structures make the particles move less, thus decreasing the ability for it transfer heat.
Geoffrey's idea is wrong because heat transfer is fastest in solids.
What is heat transfer?Heat transfer is the process by which energy is transferred from one point to another.
During the process of heat transfer, heat energy flows from hot to colder bodies.
The three processes of heat transfer are conduction, convection, and radiation.
Heat transfer is fastest in solids and slowest in gases.
Therefore, based on the nature of heat transfer, Geoffrey's idea is wrong because heat transfer is fastest in solids.

Identify and explain the purpose of the 4 major components in the refrigeration cycle?.
Answer:
compressor
Compression is the first step in the refrigeration cycle, and a compressor is the piece of equipment that increases the pressure of the working gas. Refrigerant enters the compressor as low-pressure, low-temperature gas, and leaves the compressor as a high-pressure, high-temperature gas.
condenser
The condenser, or condenser coil, is one of two types of heat exchangers used in a basic refrigeration loop. This component is supplied with high-temperature high-pressure, vaporized refrigerant coming off the compressor. The condenser removes heat from the hot refrigerant vapor gas vapor until it condenses into a saturated liquid state, a.k.a. condensation.
The expansion device
the job of a system’s expansion device is the same - create a drop in pressure after the refrigerant leaves the condenser. This pressure drop will cause some of that refrigerant to quickly boil, creating a two-phase mixture.
This rapid phase change is called flashing, and it helps tee up the next piece of equipment in the circuit, the evaporator, to perform its intended function.
evaporator
The evaporator is the second heat exchanger in a standard refrigeration circuit, and like the condenser, it’s named for its basic function. It serves as the “business end” of a refrigeration cycle, given that it does what we expect air conditioning to do – absorb heat.
This happens when refrigerant enters the evaporator as a low temperature liquid at low pressure, and a fan forces air across the evaporator’s fins, cooling the air by absorbing the heat from the space in question into the refrigerant.

What is hypertension AND how is it prevented?
Answer:
Hypertension is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure.For most adults, there's no identifiable cause of high blood pressure. This type of high blood pressure, called primary (essential) hypertension, tends to develop gradually over many years. Some people have high blood pressure caused by an underlying condition. This type of high blood pressure, called secondary hypertension, tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary hypertension, including:
Obstructive sleep apnea
Kidney disease
Adrenal gland tumors
Thyroid problems
Certain defects you're born with (congenital) in blood vessels
Certain medications, such as birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs
Illegal drugs, such as cocaine and amphetamines
Answer:
Hypertension is when blood pressure is too high. It can be prevented by doing things such as eating healthier foods, not doing any smoking, being physically active, getting enough sleep, and maintaining a healthy weight.

What does it mean that Oxygen and Water can exist in a gas state but at vastly different temperatures?
Answer: Water molecules are strongly attracted to each other, so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).

Why are meerkats affected by the plant population?
Answer:
They largely depend on it for survival as meerkats are omnivores.
Explanation:
The combined effects of hotter and drier summers and fewer plants would threaten the persistence of the meerkat population. Since they eat plants and other living bugs that usually hang out in plant-abundant areas, their [meerkats] survival depends on the range of plants near them.
Analyze the pyramid representing the energy flow through an ecosystem. Select the phrases that accurately describe the flow of energy in this ecosystem according to the image here. Select all that are correct.
A) Top carnivores obtain the maximum energy from the ecosystem.
B) Herbivores have more energy available to them than carnivores.
C) There should be fewer tertiary consumers than secondary consumers.
D) Soil organisms recycle nutrients but not energy back into the ecosystem.
E) Of the energy that is available to the producer level, only ten percent is available to the tertiary consumers.
In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.
Energy pyramid in the ecosystemThe producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.
The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.
Thus, one can effectively conclude that:
