Why do cells undergoing mitosis require one set of divisions, whereas those undergoing meiosis require two sets of divisions? what is the end result of meiosis?

Answers

Mitosis, you see, is somatic (body) cell division, and the DNA in the nucleus during Interphase can replicate by doubling the chromosomes before the actual mitosis or cell division process of splitting into TWO identical cells (and they function the same with the same number of identocal chromosomes too! So they are called Diploid cells with 46 chromosomes!)

Meiosis is sperm/egg division and must divide twice to produce FOUR sperm or egg cells. Sperm goes through I- PMAT just like mitosis, but goes through PMAT again after that! They create four Haploid gametes (sex cells) with 23 chromosomes so that when an egg and a sperm unite in sexual reproduction, the zygote (fertilized egg) will have exactly 46 chromosomes like the normal number of chromosomes in a somatic cell. ^^

How does natural selection affect animal behavior and how behaviors can affect the survival of an animal species?

Answers

The following are quick strategies for determining the relevance of a source EXCEPTa. scanning for key words
b. reading the entire source first, circling key words
c. browsing the table of contents in a book-length source.
d.looking for language from your research questions in an index.

Answers

All of the choices given are quick strategies for determining the relevance of a source except for reading the entire source first, circling the key words. This will make the correct B. 

The correct answer is option B, reading the entire source first, circling key words

Reason -

Scanning through key words is a quick strategy for determining the relevance of a source because its easy to use CTRL+F command and scan the entire document for a key just through few clicks

The index content is also a representation of the summary of the text inside the book. There is high probability that an important key word is marked in the index and thus it is easy and quick to scan an index as the text is less. Similarly, looking in table of content is also a quick process.  

But reading the entire book just to find a key word is usually a tedious task.
