Answer and Explanation:

<em>Cowbirds would be considered </em><em>an edge species</em><em>, meaning that these animals </em><em>need to live in an ecotone</em><em>. </em>

An ecotone is a transition area between two communities, or ecosystems. It is the zone of maximum interaction, and therefore with greater biological richness. The number of species is usually higher in adjacent areas, making it a meeting place for living organisms. The ecotone is usually associated with the "edge" term. The edge is the physical place where the two communities, or ecosystems meet.

The animals that live on the edge, are usually those that need two or more types of plant communities to live. In the case of the cowbird, they prefer to forage in open spaces such as grasslands, meadows, pastures and other places with short vegetation, where they can find food resources like seeds and invertebrates. They also need to lay their eggs in host nests that might be located in grasslands or forest edges over trees or shrubs where they might also roost.

The cowbirds are considered to be an edge species because they need two vegetable communities to live: open areas to feed in and forest edges to lay their eggs and roost.

The majority of cells in a human body go through mitosis and not meiosis. Is this true or false?
Andru [333]

Answer:

True

Explanation:

Mitosis results in two cells that are genetically identical. DNA replication only occurs during "S phase." Meiosis is commonly defined as a type of cell division that divides a somatic cell and produces four gamete cells when doing so.

<u><em></em></u>

<u><em>S phase:</em></u> In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

<u><em>Gametes</em></u> are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

Help with in-text citations. Answer soon, please! Paper due tomorrow.
Natali5045456 [20]
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).

this...is long. but i hope it helps! feel free to message me if you run across any special cases that give you trouble.
