name two differences and similarities between sucrose and lactose?

Answer 1

Similarities:
1.Both are disaccharides.
2.Both contain a molecule of glucose.
Dissimilarities:
1.Sucrose has glucose and fructose attached;Lactose has glucose and galactose attached.
2.Sucrose can be found in fruits, sugarcane etc.: Lactose can found in milk.

Answer 2

Differences :
1) Occurrence of sucrose is in table sugar (fruit, sugar cane, and sugar beet) while lactose is in milk sugar (cow's milk).
2) Sucrose is a non-reducing sugar but lactose is reducing sugars.
3) By using Benedict's test, sucrose solution become blue in color while lactose solution become brick-red precipitate.
4) Fructose is 1.7 times sweeter than sucrose. That's why sucrose is often used in the manufacture of sweets.

Similarities :
1) Both are disaccharides (2 monosaccharides that combined together with removal of molecule of water).
2) Both are sweet, soluble in water, and form crystal.

Answer 3

South Africa's apartheid involved White rule over the black, Indian, and mixed race populations. [Indians had immigrated to SA to work.] All these populations were part of South Africa. In Israel, the Israelis conquered West Bank and Gaza Strip in a defensive war, and maintained control of them in an effort to prevent more attacks on Israel. These lands were never considered as part of Israel. Israel itself had and has, citizens of every ethnicity and religion, including a large minority of Arab (Palestinian) Muslims. These citizens all have equality under the law. West Bank and Gaza are not part of Israel, and their people are not Israeli citizens. BTW all Jews have been expelled from Gaza. The Black "nations" in South Africa were never offered independence. Israel has long encouraged the formation of an independent Palestinian state from West Bank and Gaza. But they ask that the state recognize Israel as a state too. So far, Palestinian leaders have not been willing to say that Israel is a state. Most Palestinian leaders maintain that all of Israel should belong to "Palestine," whenever Palestine shall be founded. Israel cannot agree to this. Blacks had lived in South Africa since time immemorial, while Whites had immigrated there in the last few centuries. Jews had lived in Palestine from time immemorial, before it was ever called Palestine. Arabs had lived there for many centuries too. Islam wasn't founded until the 600s AD, so Islam is a late-comer to the region, relatively speaking. Christians had lived there since 30 AD, more or less. Christianity is not a race, of course; but then neither is Judaism. And technically, neither is Arabism, it's an ethnicity.
