Physical Oceanography

Chemical Oceanography

Biological Oceanography

Answers

Answer: Oceanography is the study of all aspects of the ocean. Oceanography covers a wide range of topics, from marine life and ecosystems to currents and waves, the movement of sediments, and seafloor geology Geological oceanography is the study of Earth beneath the oceans.

Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.

Chemical oceanography is a broad and complex study of the metamorphosis that the chemicals within oceans, living marine organisms, and the ocean floor undergo. The ocean contains a multitude of chemicals; some are natural, and others are man-made. These chemicals enter the sea in a number of ways.

Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.

why can b blood donate to AB blood?? ​

Answers


People with type AB+ blood are universal recipients because they have no antibodies to A, B or Rh in their blood and can receive red blood cells from a donor of any blood type. Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient's red blood cells.

Answer:

Type B contains the B antigen.

This type is relatively rare (second only to AB). It contains the B antigen on its red blood cells, and the A antibody (to attack A antigens) in its plasma

When a patient comes to a hospital with severe dehydration, doctors will give
them an IV filled with a salt-water solution called saline, which is isotonic with
the body's blood cells.
Why is the patient not given pure water?

Answers

Answer:

The red blood cells could burst.

Explanation:

If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.

This will result in the red blood cells becoming swollen and even potential  bursting.

The library has 2 rows of 7 seats. People are sitting in the first two seats in each row. How many seats are empty? Based on the reading above identify two pieces of evidence that show that Judaism unified the Jewish peopleStarting around 597 BC, the Babylonian Empire, centered in the city of Babylon in the Fertile Crescent, conquered the Kingdom of Judah. The upper class Jews, Israelites who lived in Judah, were ordered by the Babylonian King, Nebuchadnezzar II, to leave Jerusalem and live in captivity in Babylon.The period of time from 597 to 539 BC which ended when the Persian king Cyrus the Great took over Babylon and allowed the Jews to return to Judah is known as the Babylonian Exile or Captivity.This period had a great effect on the Jewish people. They wondered how such a terrible thing could happen to gods chosen people. In addition, their sacred temple where they worshiped their god was destroyed. As a result, some of the Jewish people in Babylon became more religions. They commemorated the fall of Jerusalem with days of prayer and celebrated the Sabbath (day of rest set aside for religious reasons). The profession of the scribes, people who copied religious documents, grew in importance. Historical writings and religious teachers were compiled and revised by the scribes to create the Torah. The writers viewed the recent events as punishment for their sins, especially the sin of worshipping gods other than Yahweh. At the same time, the scribes and others in exile hoped that the Jewish faith would bring the Israelites together and that they would be able to rebuild the Temple once the exile was over. The Babylonian exile represents both one of Judaism's darkest hours and also the beginning of its history as an enduring universal religion that gave birth to the later monotheistic traditions of Christianity and Islam.
