It’s A an generation that’s the only one that makes sense because evolution is a change over time too
False they bond together using peptide bonds.
Answer:
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.
Prior to 1900, sea levels rose at maximum, 4 cm per year. Since 1900 sea levels have risen 11 cm per year.
<h3>How sea level is measured?</h3>
- Tide stations and satellite laser altimeters are the main tools used to measure sea level.
- The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
- NASA uses satellites to measure sea level all over the world.
- Height of the ocean's surface, often known as sea level, is measured by the Jason-3 satellite using radio waves and other equipment.
- It studies how the global sea level is changing over time for the entire Earth every 10 days.
- The average sea level is 6,371.001 km (3,958.756 mi), and it is 6,356.752 km (3,949.903 mi) at the poles.
