Scientists Investigate Sex Determination in Alligators
The sex of some reptiles, including the American alligator, is determined by the temperature at which the eggs are incubated. For example, incubating them at 33°C produces mostly males, while incubation at 30°C pro...
The placenta secretes progesterone and estrogen during pregnancy. Progesterone is responsible for the following functions:
• maintains the lining of the uterus
• inhibits (interferes with) contractions of the uterus
• inhibits the production and release of eggs
Describe one likely result if the placenta became damaged and could not maintain progesterone levels. Support your answer. 
After being absorbed, long fatty acids come together to reform triacylglycerides and cholesterol esters. Short fatty acids pass directly into the blood where they bind albumin protein and get transported to the liver.
Fatty acid are hydrocarbon chains with carboxylic acid at the end. Unsaturated fatty acid contain one or more double bonds, usually in cis conformation. There are two methods of naming the unsaturated double bonds, delta and omega.
Delta naming system:
1. Count carbons starting from the carboxylic end. The total number of carbons in the fatty acid is the first number in the name.
P.S. How are proteins made?
DNA is used as a template to make RNA in a process called transcription. RNA is single stranded and has the base U instead of T. Once RNA is modified, it leaves the nucleus and enters the cytoplasm. In cytoplasm, mRNA together with tRNA and ribosomes does the process of translation, or creation of proteins. tRNA reads the codon (3letter sequence) on mRNA and bring the correct amino acid to th...
Cytoplasm is the fluid that fills the cell and contains all organelles and cell parts. In a multicellular organism, excretion system excretes all the wastes our body produces. Immune system protects our body from pathogens and helps prevent sickness. Reproductive system is responsible for the sexual characteristics as we well as allowing us to reproduce and form a new generation.
