Sex Chromosomes



The sex chromosome is the 23rd pair. It determines weather or not the baby is a boy or a girl. Chromosome pairs that are XX are girls, and XY is a boy. The process where the sperm determines weather it is a girl or a boy, is called meiosis.

Reflection: I learned that the 23rd pair is the only pair that determines the sex of a baby. Weather the fertilized sperm to gets to the x chromosome or the y chromosome, that is the sex of the baby. The sex of the baby is roughly equal between a boy and a girl.

    Good explanation of the topic. Could have put a little more on the first paragraph. Didn't add how to use outside of class.

Anaerobic Energy Production - MORGAN BANKS

Image
ANAEROBIC ENERGY PRODUCTION  Anaerobic Energy Production is one form of Cellular Respiration  This form requiers no oxygen  Is used for a fast burst of energy Occurs mostly in prokaryotes cells  Fermentation 1- lactic acid (makes muscles sore)  2- Alocholic REFLECTION - Anaerobic Production has no oxygen, therefore many of the things we do, do not involve anaerobic production! It involves the aerobic energy production. This is not only a good review for you but for me as well on how to justify the two.  http://slideplayer.com/slide/9078035/ MORE INFO: http://www.diffen.com/difference/Aerobic_Respiration_vs_Anaerobic_Respiration VIDEO/QUIZ:  http://study.com/academy/lesson/anaerobic-exercise-definition-benefits-examples.html

Genetic Variation: Mutations

Image
What is a mutation? A mutation is any change in the DNA sequence.  There are three types of mutations: * addition: One or more nucleotide base pairs are inserted into a DNA sequence (also called frameshift mutation)  *deletion: The removal of one or more nucleotides in a DNA sequence (also called frameshift mutation) *substitution: A mutation that exchanges one or more bases for another (also called point mutation) How do they occur & why? Mutations for randomly, but different mutations occur different ways.  Most of the time a mutation comes from radiation (so like the sun, X-rays, tanning salons, etc). Some mutations can be genetic though, like autism. Autism is caused when theres an extra chromosome. Another common mutation would be cancer. Cancer occurs when cells uncontrollably grow, and don't die.  Can it be prevented?  Unfortunately, mutations are random. The best way to prevent them is to protect yoursel...
