Why are different types of cancers named based on where in the body they originate (breast cancer, skin cancer, bone cancer, etc.)? Why does it matter from which organ or tissue type the cancer developed?
Answer:
Cancer is caused by abnormal cell division. However, a skin cell is different from a bone cell. Because of that, the cancers that can occur behave differently.

Match the following terms pertaining to Earth's early formation with the correct description.
The process on the accumulation of ice and rock to form the early earth is called as accretion.
What is accumulation?Accumulation is defined as the ongoing accumulation of foreign compounds inside an organism, such as harmful chemicals or insecticides. Accumulation in the context of trading refers to the size of a position within an asset that increases as a result of multiple transactions. Accumulation also denotes the incorporation of positions across the board in a portfolio. It can also be used to describe a rise in buying activity inside an asset.
Differentiation is defined as the procedures that turn immature cells into mature ones with particular activities. Iron catastrophe is defined as a huge geological event that is thought to have occurred early in Earth's history and during which heavy metals like iron and nickel gathered in the core for a geologically brief time. Earth's layer include Crust, mantle, core, lithosphere, asthenosphere, mesosphere, outer core, inner core.
Thus, the correct match of the following is 1, 2, 3 and 4 is C, B, D and A.

A chemical reaction in which molecules combine by removing water
O Hydrolysis
O Water-removal connection
O Dehydration reaction
Answer:
Hydrolysis
Explanation:
Also known as condensation, it is a chemical reaction involving the joining together of two molecules with the removal of a molecule of water. Molecules which are formed in this way can usually be broken down by the addition of water molecules, a process known as “hydrolysis.” A chemical reaction involving the removal of a water molecule.
Answer:
The first one.... Hydrolysis.
Explanation:
Certain molecules can be joined by the removal of water in a process called:
hydration... hydrolysis...neutralization... and condensation.
Which type of carbohydrate would provide an immediate source of energy
Answer:
glucose carbohydrates
Explanation:
As an immediate source of energy, glucose is broken down during the process of cellular respiration, which produces ATP, the energy currency of the cell. Glucose or blood sugar, is the main source of energy for your body's cells, tissues, and organs.

What are the components of a lipid?
a. Lipids are made of made of carbons bound to hydrogen and oxygen groups; these often form high-energy ring structures
b. Lipids are made of long chains of carbons bound to hydrogens, called hydrocarbons
c. Lipids are made of carbons bound to hydrogen, oxygen, nitrogen, and phosphorous groups; these are often bound into single and double-ring structures
d. Lipids are made of carbons bound to hydrogen, oxygen, and nitrogen groups; the unequal sharing of electrons around the oxygen (carboxyl) and nitrogen (amino) groups cause the molecule to fold up on itself and form different shapes that affect the function of the molecule in the living organism
Answer: D
Explanation:
Lipids are made of carbons bound to hydrogen, oxygen, and nitrogen groups; the unequal sharing of electrons around the oxygen (carboxyl) and nitrogen (amino) groups cause the molecule to fold up on itself and form different shapes that affect the function of the molecule in the living organism.
Describe the relationship between the wavelength and frequency of electromagnetic waves
Answer:
Frequency is inversely proportional to wavelength.
Explanation:
frequency is the number of oscillations in a unit of time.
Wavelength is the length between one oscillation and the next oscillation.
take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)
Now get two pins and pin them at a certain distance apart.
take the first spring and attach its two terminals to the pins.
Repeat the above procedure, but double (increase the distance x2) the distance between two pins.
Now you have to measure how many coils are there within 5cm of the two springs.
you'll observe that the second spring has half the coils of the first spring within 5cm.
In here no. of coils is the frequency
5cm length is time.
distance between coil is the wavelength.

Por qué el melanismo industrial es un tipo de selección direccional
El melanismo industrial es el fenómeno genético por el cual lepidópteros que viven en zonas industriales tienen un color oscuro. Este fenómeno se debe a que la selección natural favorece un determinado genotipo.
La selección natural es el principal mecanismo por el cual las especies y los organismos evolucionan (cambian) para adaptarse a su ambiente.
La selección natural se define como la supervivencia y reproducción diferencial de los individuos mejor adaptados a su ambiente.
Este proceso (selección natural) tiende a modificar las frecuencias de génicas (alélicas) y genotípicas las cuales determinan los rasgos adaptativos a lo largo de las generaciones.
La selección direccional es un tipo de selección natural que tiende a favorecer a un sólo alelo a lo largo del tiempo.
En el melanismo industrial, los lepidópteros (polillas) que expresan el alelo que codifica para el rasgo fenotípico 'color oscuro' se ven favorecidos porque esta característica les permite mimetizarse en un entrono ambiental oscuro causado por la polución ambiental de zonas industriales.

Einsteins Theory of Relativity can be
supported with evidence of light doing
what around the sun?
In 1919 observation of a solar eclipse confirmed Einstein's prediction that light is bent in the presence of mass. This experimental support for his general theory of relativity garnered him instant worldwide acclaim. ... This has been measured directly and also through the gravitational redshift of light.
Answer:
The Earth moves around the Sun, due to the Sun's gravity. ... According to Newton's theory, the Earth should know immediately that the Sun had disappeared. But Einstein said that couldn't be right. Because, according to him, nothing can travel faster than the speed of light — not even the effects of gravity.
Explanation:
•Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same•for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.
•Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends
