Explanation:
1- the purpose of blood flow-circulatory system- is to convey Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries and capillaries away from the heart, to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.
2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied through the bicuspid valve into the Left.Ventricle.
During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.
Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is forced through the aortic valve to empty into the aorta into the systemic circulation,branches of the carotid artery supplies the heart from the aorta.
The Whole cycle continues.
1. information is transcribed in DNA to mRNA
2. mRNA leaves the nucleus
3. ribosome attaches to the mRNA
4. tRNA anticodon carries an amino acid that compliments the mRNA codon
5. the chain of amino acid forms a protein
Answer:
D. All of the above.
Explanation:
Recommended Dietary Allowance (RDA) is a term that refers to the amount of vitamins, minerals and protein that should be consumed daily to meet the nutritional needs of most individuals and groups of people in a healthy population. The RDA should be recommended by a nutritionist, in addition it is noteworthy that the RDA can be used as a guideline to provide nutritional adequacy for micronutrients and often the RDA values are different for men and women.
