The source of evidence refers to C. where the information came from.

There are two sources of evidence the primary or original source or evidence and secondary source. The primary source, in history, is anything that serves as an original source of information about the topic. It could be an artifact, document, manuscript, diary, autobiography and the like. Moreover, in the field of journalism, a primary source can be a person that has a personal or direct knowledge of a subject or situation or a written document by such a person. Meanwhile, secondary sources are evidences or sources that are extracted or build upon primary sources.

That’s wrong answer is it could be used to exsplain the behavior of all elements

Solution 2
It helped scientists discover new elements
Question
Identify the four principles of natural selection
Solution 1
Variation- Heritable differences that exist in every population are the basis for natural selection
Overproduction- Competition for resources for resources
adaptation- A trait that helps an organism survive and reproduce
decent with modification- Natural Selection will result in species with adaptation that are well suited for survival and reproduction.
Question
Which of the following is an example of an environmental variation? a Marge dyes her hair blue. b Homer inherited baldness from his father's side of the family. c Apu is a tongue roller, but his brother Sanjay is not. d Bart is a boy because he has an X and a Y chromosome.
Solution 1
I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.
Solution 2

Answer:

A. Marge dyes her hair blue

Question
Help asap plz (IM GIVING AWAY 70 POINTS) 1. How are wavelength, frequency, and energy related to each other? 2. Give one example of a type of energy that is considered electromagnetic radiation. 3.How do we use electromagnetic energy? 4. What is the electromagnetic spectrum? 5. Name the only part of the electromagnetic spectrum that humans can see with the naked eye. 6. What are the characteristics of visible light? 7. Red light has the __________ wavelength. 8. Violet light has the __________ wavelength. 9. What is ‚ÄúRoy G. Biv,‚ÄĚ and what does it stand for? 10. Even though sunlight looks white, what is it really made up of? 11. What object can you use to bend light? 12. What does the SAGE instrument measure?
Solution 1
1 is¬†The greater the¬†energy, the larger the¬†frequency¬†and the shorter (smaller) thewavelength. Given the relationship between¬†wavelength¬†and¬†frequency¬†‚ÄĒ the higher the¬†frequency, the shorter the¬†wavelength¬†‚ÄĒ it follows that short¬†wavelengths¬†are more energetic than long¬†wavelengths.

2 is he Sun & its Energy. The sun's energy is the primary source of energy for all surface phenomena and life on Earth.
Combined 
with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this energy provides for the immense diversity of life formsthat are found ...  

3 is The light that we see is a type of electromagnetic radiation. However it is only a very small part of the entire electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum.Electromagnetic radiation is different from sound in that it can travel in space and does not need a medium like air or water to travel


 
Solution 2

You could use a diamond to bend light and you could also use water.

Question
Which of the following is a source of genetic variation in a population? a Differences due to a car accident. b Differences due to a hairstyle choice. c Differences due to inherited genes.
Solution 1

Answer: c Differences due to inherited genes.

Gene flow or gene migration is an important source of genetic variation. It is a movement or transfer of genes from one population to another.  It can take place between two populations of the same species through migration and is brought by reproduction and vertical gene transfer from parent to offspring.

Question
All mutations are harmful. True False
Solution 1
False, However not all mutations are harmful, there are very few number of mutations that actually can change the codes for a better functioning protein. In this case they will be beneficial. Here we are testing for potentially harmful mutations in human genes.
Solution 2
I think it's false. Not 100 though
Question
The term pseudoscience refers to evidence that _____. A. supports a product claim B. was created by a reliable source C. pretends to be scientific, but actually is not D. was gathered during a scientific experiment
Solution 1
The prefix pseudo means "not genuine", or fake. 
So your answer is: C. Pretends to be scientific, but actually is not.

Question
Which statement best describes energy of an ecosystem? A.The amount of energy entering an ecosystem from the Sun is equal to the amount lost as heat. B. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms. C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat. D. The amount of energy entering an ecosystem from the sun does not transfer from organism to organism.
Solution 1

The energy of the ecosystem can be best described as option C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.



Solution 2

The correct answer is option C

The only source of energy in an ecosystem is the sun. The green plants make food by the help of photosynthesis. These plants are also eaten by the herbivores and then these herbivores animals are eaten by the carnivores animals present in the ecosystem.

The energy from the sun is transferred to herbivores, then from herbivores to carnivores.

Some amount of energy is also lost during the process of energy transfer.

The energy transferred from one level to another + the energy lost

= energy absorbed from the sun.

Question
What is a system responsible for transporting materials such as oxygen,digesting foods,wastes and hormones throughout the body?
Solution 1
The circulatory system.

It transports oxygen around (with the help of the lungs)
It transports nutrients (amino acids, electrolytes)
It transports wastes (with the help of the kidneys)
it transports hormones (with the help of various endocrine glands)

I hope this helps! I'm happy to answer any other questions you might have :)
