John Dalton (1766 - 1844) was an English chemist who is primarily known for his atomic theory, which although it is about two centuries old and has progressed in the meantime, is still valid. According to his theory, all elements, matter, are made of atoms, and that all atoms in the given element have the same mass and property, while the compounds are formed from several different types of atoms, where the chemical reaction of two or more elements represents the rearrangement of atoms.

The answer is: B)

Why were the Caribbean islands not as united as the mainland colonies
nata0808 [166]

The authentic scenery of the Caribbean uncovers the basic work the area played in the common clashes of the European powers since the fifteenth 100 years. In 1492, Christopher Columbus showed up in the Caribbean and affirmed the district for Spain.

Why are some Caribbean islands not free?

Not many out of each and every odd island/country in the Caribbean is free. Sadly, many are at this point agreed with past boondocks domains, including France, the Netherlands, and the Bound together Domain. Some that refined independence from Britain are by and by ward space countries with Sovereign Elizabeth II as their ruler and head of state.

The following year, the essential Spanish settlements were spread out in the Caribbean. But the Spanish triumphs of the Aztec space and the Inca domain during the sixteenth century made Mexico and Peru more supportive spots for Spanish examination and settlement; the Caribbean remained definitively huge.

Do you think woman and man should have different roles in the running of a home based on gender? Discuss.
Alekssandra [29.7K]

Answer:

No.

Explanation:

This is not the nineteenth century where there are housewives doing all the household chores whilst the men go off to work and provide for their family. Sure, there are some countries like Uruguay where the female children are taught they have to wash the dishes and fold and iron the clothes whereas if they have a brother, their brother does not. However, I do not find this rigtheous whatsoever. Everyone is equal; we should not discriminate or delegate tasks depending upon our genders.
