We know that a meteor of the same mass will fall to earth, and a meteor of the same mass will fall to Jupiter sooner and harder because of Jupiter immense gravity.
The heart is in the diastole phase. In the diastole phase, the heart muscle relaxes and allows the chambers to fill with blood in preparation for the next cycle. In the systole phase, on the other hand, the heart muscles contract and this causes the ejection of blood into the aorta and pulmonary trunk.
The answer is A.
Prokaryotic organisms are simpler than eukaryotic organisms are are single-celled. They do not contain the genetic information to form complex, specialized structures as eukaryotes do, so they cannot form multi-cellular bodies. The remaining options apply to both prokaryotes and eukaryotes.
Primary sources means that it is original article or book created by an individual or sometimes a group of people. What types of primary sources are available? It might be surprising to know that a novel is a primary source. Other types of primary sources are paintings created by the artist. If it were a photocopy of the painting, then it would be a secondary source. Some other primary sources are letters, films, short stories, plays, poems, photographs, court cases, journal articles, newspaper events, and speeches. For instance, a speech by President Bush would be a primary source.
Secondary sources are sources that are written about primary sources. Secondary sources analyze, interpret, and discuss information about the primary source. If a magazine writer wrote about the speech President Bush gave on September 11th, it would be a secondary source. The information is not original, but it is an analysis of the speech.
