Infrared radiation A) Heat from warm objects, used to detect the location of objects Microwaves B) All the radiation humans can see, ranging from red to violet Ultraviolet light C) Used in radar and to heat food Visible light D) Given off by very hot objects, such as the sun
Answers
Answer:
Infrared radiation → A) used to detect the location of objects
Microwaves → D) Used in radar and to heat food
Ultraviolet light → C)Given off by very hot objects, such as the sun Heat from warm objects
Visible light → B) All the radiation humans can see, ranging from red to violet
Explanation:
Microwaves have magnetic waves with very long lengths, greater than that of infrared light. These waves are produced through vibrations that produce heat, as the microwave is turned on, which allows the food to be heated. These waves are also used to provide communication on some types of devices.
Infrared radiation is a type of non-ionizing radiation that has a low frequency and therefore cannot be visualized, since it is not within a visible electromagnetic spectrum, having a frequency lower than red. It can be used to detect the licalization of objects and does not pose a health risk.
Ultraviolet radiation is extremely harmful to our body. It is characterized by radiation with very small wavelengths, less than 400nm. This type of radiation can be released by the sun and ultraviolet lamps.
Visible light refers to the simplest form of electromagnetic wave and covers all the radiation that our eyes can see, allowing different colors to be seen in the objects we observe according to the reorganization of atoms and molecules.
Answer:
A=Microwaves
B=Ultraviolet light
C=Visible light
D=Infared radiation
Explanation:
A) Used in radar and to heat food
B) Given off by very hot objects, such as the sun
C) All the radiation humans can see, ranging from red to violet
D) Heat from warm objects, used to detect the location of objects

The exoskeleton of a housefly is made up of
A.keratin. B.chitin. C.lignin. D. All of the above
Answers
Answer:
Chitin
Explanation:
A fly's main body is made of a thorax and an abdomen. These parts are covered by a hard exoskeleton made of a bony substance called chitin.
The exoskeleton of a housefly is made up of chitin. Thus, the correct option for this question is B.
What is Exoskeleton?The Exoskeleton may be defined as a tough and rigid external covering present in some invertebrate animals like arthropods. It supports and protects the animals with respect to their external environment.
The main body of a housefly is significantly divided into two regions, i.e. a thorax and an abdomen. The thorax region is further divided into three parts i.e. prothorax, mesothorax, and metathorax.
All these parts of a housefly are remarkably covered by a tough exoskeleton that is constructed of chitin. The housefly has a hard exoskeleton that protects it from moisture loss.
Therefore, the exoskeleton of a housefly is made up of chitin. Thus, the correct option for this question is B.

Base your answers to questions on the food web below and on your knowledge of science. Answer each part below. A. Which organism labeled in this food web provides energy, either directly or indirectly, to all of the other organisms? Explain why this is your answer. B. Explain why the amount of food available to the slug population might increase if the aphid population decreased.
Answers
Answer A:
The organism which provides energy directly and/or indirectly to all of the other organisms is the garden plants.
Explanation:
Plants are generally found at the lowest part of the pyramid/food chain. They are also called Autorotrophs because they are the primary producers of energy from which the entire pyramid feeds off.
The other animals/organisms on the pyramid are called Heterotrophs because they depend directly or indirectly on the primary energy producers.
Answer B:
The Slug and the Aphid feed are herbivorous. So they are in competition for the garden plants. If one of them, for some reason, decreased in population, the other will have more food to eat.

Scientists often work on projects for a long time and fail to see sources of error in their research. Which process allows an outside expert to look at the scientist's project and point to sources of error? direct funding peer review conclusive research data collection
Answers
Answer:
The correct approach is Option B (Peer Review).
Explanation:
Rather made reference to someone as a scientific peer-review, it encourages the specialist who has not been essential to the study team to analyze the study objectively and pointed out everyone's mistakes. It serves as major self-regulation for scholars and aims to make the publishing process somewhat credible. Hence, the solution to this issue is Peer Examination.Funding organizations rarely have the capabilities to recognize out mistakes, whereas definitive analysis is a method of study that helps to make a definitive statement. The gathering of data is simply a process of scientific study.Other approaches do not apply to the example mentioned. Although the one mentioned is right.

A chemist forms 16.6 g of potassium iodide by combining 3.9 g of potassium with 12.7 g of iodine. Show that these results are consistent with the law of conservation of mass.
Answers
The sum of the masses of potassium and iodine equals the mass of the product, potassium iodide. The results are consistent with he law of conservation of mass.
Hope this heeeelllllllpppppppp
The law of conservation of mass states that mass can neither be created nor destroyed by chemical reactions or physical transformations.
The mass of potassium iodide can be calculated from the sum of the mass of potassium and iodine.
The mass of potassium iodide is as follows:-
[tex]Mass\ of \ potassium\ iodide=3.9\ g+12.7\ g\\=16.6\ g[/tex]
So, the total mass of potassium iodide is equal to the mass of potassium plus iodine. So, these results are consistent with the law of conservation of mass.

Choose your favorite super hero that gained their powers from radiation. What
type of radiation gave them their powers? Choose a wavelength that falls inside
that spectrum. Calculate energy (SHOW WORK).
Answers
Answer:
Copy and paste "Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz." into google, and the correct website pops up as the first result.
Explanation:
I tried to link the website that I use to convert wavelengths and frequencies into types of light, but it deleted my answer, so I guess we're doing it this way. As for converting the wavelength to energy, the same principles apply as before:
Frequency: ν Wavelength: λ Energy: E Speed of light: C (3.00e8) Planck's Constant: h (6.626e-34)
ν -> λ λ = C/ν
λ -> ν ν = C/λ
For either of these equations, wavelength must be converted to meters or nanometers, depending on the equation.
For ν -> λ, after doing the equation, convert the wavelength into nanometers by dividing by 1e-9.
For converting λ -> ν, convert the wavelength into meters by multiplying by 1e-9.
For energy: E = hν = hc/λ
