Answer:
d. Ethos
Explanation:
The correct answer is actually D.
Ethos is usually referred to one's credibility when making an argument. It has to do with using one's trustworthy personality to persuade. This is a reason why ethos is employed in advertising a product or brand.
One with a good ethos is usually respected and regarded. Since celebrities like footballers, actors, athletes, etc., have influence and are respected in their societies, therefore advertisers tend to use them in endorsing their products because people love and believe them. So, people end up using those products because a celebrity endorsed it. The celebrities are usually paid for the endorsement.
Answer:
A plant cell
Explanation:
In the given question, a stage of a cell has been described during cell division.
The characteristic of this cell division are:
1. Nuclei are formed at opposite poles- shows that it is the stage of cell division
2. The formation of cell plate- the cell plate is formed in the middle of the cell which indicates that the cell is a plant cell.This cell is a plant cell as the cell plate is formed only in the plant cells and not in the animal cell in which the contractile rings are formed.
Thus, A plant cell is correct.
Answer:
The weather of San Francisco gets colder with the California current.
Explanation:
The template California´s current oceanic ecosystem is one of the most productive and diverse in the world.
The California current flows from the northern latitude, running along the occidental coast of North America, forward to the South.
The cold current makes coasts colder than the east coasts. When winds blow from the sea, they bring cold air over the land because the cold California current lowers the air temperature. Even more, winds coming from the northwest originate upwellings that bring colder water from the bottom, lowering, even more, the current temperature.
Thus the temperature of California’s coastal cities, such as San Francisco, is relatively cool.
Well , the humans have a closed double circulatory system as the blood passes by the heart twice per one cycle and doesn't leave the blood vessels like in insects.
》Pulmonary circulation : Blood is circulated to the lungs where it is oxygenated.
》Systemic circulation : Blood is circulated through all the other parts of the body where it unloads oxygen.
Oxygenated blood coming from the lungs enters the heart through the pulmonary vein which takes blood to the first chamber it meets ; the Left atrium. Left atrium pumps blood to the second chamber , which is left ventricle and during this time , the semi lunar valves are closed to prevent back flow of blood and the bicuspid valve will be open . Now , the left ventricle is filled with oxygenated blood so it will pump this blood to the whole body via the largest artery which is Aorta.
Oxygenated blood will unload oxygen to cells in need of it and will return back now to the heart as deoxygenated . This deoxygenated blood will enter the heart through superior and inferior vena cava which will take the blood to the third chamber , right atrium . Right atrium will pump blood to right ventricle so the semi lunar valves will be closed during this time and the tricuspid will remain open. Now that the fourth chamber is filled with deoxygenated blood , it will pump this blood through pulmonary artery when the semi lunar valves opens , to the lungs again to be oxygenated once more.
Notice that you have to know exactly the position of the valves that I have mentioned in the heart so that you could understand the blood flow better. You can refer to any heart labelled diagrams in your textbook or the internet.
