<span>It is a membranous sac attached to an embryo, functioning as the circulatory system of the human embryo before internal circulation begins until about 3 weeks of age if I recall. It also forms the umbilical cord. A collet is used for clamping purposes. It forms a collar around an object, and clamps down on it as it is tightened. A 5C collet has external threads used for lathes..</span>
Answer:
6.4 million
Explanation:
The human genome contains 3.2 billion bases (nucleotides).
Each reaction can sequence a read length of 500 nucleotides. We are excluding overlaps, and redundant sequences (which in reality would always happen when performing sequencing). Therefore, the minimum number of sequencing reactions is the total number of nucleotides in the genome divided by the length of read 3.2 billion ÷ 500 = <u>6.4 million</u>
Answer:
Rapid eye movement sleep (REM) may be defined as the the phase of the sleep that are unique to the mammals. This sleep is marked by the muscle tone.
The REM leads to the increase in pressure with deprivation. This leads to the increase in the rapid eye movement and plays an important role in the REM sleep and dreaming of the individual and quite necessary in the adult.
Natural selection is one of the basic mechanisms of evolution during which those variations in the genotype that increase organism's chances of survival and procreation are preserved and multiplied from generation to generation at the expense of those that are less advantageous. In this case the following are postulates of natural selection; Individuals with certain traits are more likely to survive and reproduce, individuals in a population vary more likely to survive and reproduce, survival and reproductive success are variable among individuals in a population and lastly some traits differences are heritable.
Once the alcohol goes into our system, an ounce of it is process for a period of one hour.
The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.
Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.
