Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions.

Question: "What causes a variance in traits throughout reproduction?"

Answer: "Offspring"

Response: no

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "Based on the explanation in the article, why do you expect to happen with the water and oil?"

Answer: "They will mix easily"

Response: no

Assisting Zionist causes Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors. Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university. He also submitted various suggestions as to its initial programs. Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development. Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important. Chaim Weizmann later became Israel's first president. Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post. The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons". Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it.

Question: "What are the important positions Chaim Weizman held in Israeli/Zionist history?"

Answer: "Second President of Israel"

Paul put the despised watch away And laid out before him his array Of stones and metals, and when the morning Struck the stones to their best adorning, He chose the brightest, and this new watch Was so light and thin it seemed to catch The sunlight's nothingness, and its gleam. Topazes ran in a foamy stream Over the cover, the hands were studded With garnets, and seemed red roses, budded. The face was of crystal, and engraved Upon it the figures flashed and waved With zircons, and beryls, and amethysts. It took a week to make, and his trysts At night with the Shadow were his alone. Paul swore not to speak till his task was done. The night that the jewel was worthy to give. Paul watched the long hours of daylight live To the faintest streak; then lit his light, And sharp against the wall's pure white The outline of the Shadow started Into form. His burning-hearted Words so long imprisoned swelled To tumbling speech. Like one compelled, He told the lady all his love, And holding out the watch above His head, he knelt, imploring some Littlest sign. The Shadow was dumb.

Question: "What types of stones were Paul's watch adorned with?"

Answer: "Foamy stream"

Response:
yes
