When a gummy bear shrinks, is that considered hypertonic or hypotonic?
raketka [301]

Answer:

Hypertonic

Explanation:

In hyper-tonic solutions, the cell will shrink and crenate. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypo-tonic solution, the gummy bear will expand in size and volume due to the water entering it.

What's the best way to avoid plagiarism when taking notes from your primary sources?
Nataliya [291]
Plagiarism is an act of fraud where you delivered biased or incorrect form in some way.

Ways to avoid Plaiarism:

Paraphrase - Read it and put it into your own words. Make sure that you do not copy verbatim more than two words in a row from the text you have found. If you do use more than two words together, you will have to use quotation marks. We will get into quoting properly soon.

Cite - Citing is one of the effective ways to avoid plagiarism. Follow the document formatting guidelines (i.e. APA, MLA, Chicago, etc.) used by your educational institution or the institution that issued the research request. This usually entails the addition of the author(s) and the date of the publication or similar information. Citing is really that simple. Not citing properly can constitute plagiarism.

Quoting - When quoting a source, use the quote exactly the way it appears. No one wants to be misquoted. Most institutions of higher learning frown on “block quotes” or quotes of 40 words or more. A scholar should be able to effectively paraphrase most material. This process takes time, but the effort pays off! Quoting must be done correctly to avoid plagiarism allegations.

Citing Quotes - Citing a quote can be different than citing paraphrased material. This practice usually involves the addition of a page number, or a paragraph number in the case of web content.

Citing Your Own Material - If some of the material you are using for your research paper was used by you in your current class, a previous one, or anywhere else you must cite yourself. Treat the text the same as you would if someone else wrote it. It may sound odd, but using material you have used before is called self-plagiarism, and it is not acceptable.

Referencing - One of the most important ways to avoid plagiarism is including a reference page or page of works cited at the end of your research paper.

Again, this page must meet the document formatting guidelines used by your educational institution. This information is very specific and includes the author(s), date of publication, title, and source. Follow the directions for this page carefully. You will want to get the references right.

Explain how the independent alignment of homologs, and also crossing-over during the first meiotic division, each contribute to
BartSMP [9]

Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.

Explanation:

Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)

Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>

After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>
