Answer:
- Independent assortment of chromosomes
- Crossing over
Explanation:
Independent assortment of chromosomes
We each have a diploid genome that is used to make haploid gametes. The selection of which combinations of chromosomes (and the particular alleles they hold) that are passed on to the gametes is random. I.e. 1 gamete could have the paternal chromosomes 1, 4, and 6, and maternal 2, 3 and 5. Another gamete could have paternal 2, 4, and 6, and maternal 3 2 and 5.
This produces unique combinations of alleles that are passed onto the next generation after sexual reproduction.
Crossing over
Crossing over occurs when homologous chromosomes pair up and align during meiosis. When this happens, they can exchange genetic material at homologous sites. This means that even <em>within </em>chromosomes, there are new combinations of alleles being created to pass on to the gametes before sexual reproduction. That is, each chromosome will have chunks of maternal and chunks of paternal DNA.
Both of these features increase genetic variation by two mechanisms, and this is occurring in two individuals, producing genetically diverse offspring.
Options for the question have not been provided. They are as follows:
a) if minority group students experience less academic success, they may find themselves in classes with proportionally fewer majority group members.
b) majority group students do not want to interact with minority group students, so they select classes that fewer minority group students will take.
c) gangs in the schools are not integrated.
d) academic success has little to do with the two group interactions.
Answer:
a) if minority group students experience less academic success, they may find themselves in classes with proportionally fewer majority group members.
Explanation:
The educators have decided to open various classes where the majority and the minority group students can interact with each other. However there is a loophole in this plan. A student will choose a class not only on the basis of their liking but also on the basis of their academic level of comfort. Minority group students usually face similar environment and set of problems since they belong to a small close knit minority community and so they might also show similar academic performance.
For example, most of them could be bad in math since their early schooling in their own community could not build a strong foundation for math. As a result they would not perform well in it and will automatically be a part of activity not related to math. Unintentionally they will get clubbed together again in classes and activities with fewer majority group members.
Domains are the highest ranking of organisms in taxonomy. They are notably Bacteria, Eukarya, and Archaea
B. The reason we have the nomenclature (name) system we have is because it can reveal more about the animal. For example, it tells our genus and our species. Just the common name can apply to anything
