Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.
Explanation:
Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.
From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.
From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.
Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.
Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.
The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.
In ecology, a group of particular organisms which live in a community is called POPULATION.
For instance, all the number of lions which live in a community make up the population of lions in that community. Populations of different species of animals that are found in that area combine together to form the community.
Answer: Located within the thermosphere, the ionosphere is made of electrically charged gas particles (ionized). The ionosphere extends from 37 to 190 miles (60-300 km) above the earth's surface. It is divided into three regions or layers; the F-Region, E-Layer, and D-Layer.
Explanation:
In-text citations are for any information you got from another source. if you directly quote it, you need an in-text citation; if you summarize it, you need one; if you paraphrase it, you need one.
APA format in-text citations require three things if available: the author's name, the year, and the page number. for parenthetical citations, it's formatted like so: (Smith, 2002, pp. 91)
however, signal phrases change things. signal phrases are your lead-ins to quotes, like, "According to John Smith" or "An article by Jane Doe" -- HOWEVER, in APA format, you're required to put the year in the signal phrase if you mention the author. "According to John Smith" becomes "According to John Smith (2002)," and you continue your sentence like normal.
if no author is available, cite it by the title of the web article. for example: ("Camping," 2001). if no page number is available, as is usually the case with web sources, leave it out.
remember that if you say the article/page number/author's name IN your signal phrase, the same information doesn't need to be repeated in your in-text citation. you only need to give the information once, because they'll be able to find it on your reference page:
According to John Smith (2002), mosquitoes prefer humid weather (pp. 9).
Mosquitoes prefer humid weather (Smith, 2002, pp.9).
According to page 9 of "The Great Outdoors" by John Smith (2002), mosquitoes prefer humid weather.
note that for the last one, no "end of the sentence" in-text citation is needed, because you gave all three pieces of info within the sentence.
an easy way to remember the difference between MLA and APA is that APA emphasizes the date of your source more. it wants the year as soon as you reference your author. this is because in science fields, discoveries are often made then later revised, so they want to know what year you got your information from. outdated information could be considered like invalid or whatever so dates matter A Lot for science!!
MLA format is actually easier. all you have to do for the in-text citations is the author's last name and page number, or the article title. no dates are needed in-text.
as an example: (Smith 9)
no "pp." is needed as they require in APA format. just the name, then a number for the page. that's it. if you say the author's name in your signal phrase, you only need to give the page number:
According to John Smith in his book "The Great Outdoors," mosquitoes prefer humid weather (9).
According to "The Great Outdoors," mosquitoes prefer humid weather (Smith 9).
According to page 9 of "The Great Outdoors," mosquitoes prefer humid weather (Smith).
