How do scientists know that dark matter and dark energy exist even if we can not see them

Answers

Answer 1

Dark matter has been given this name because it doesn't seem to interact with regular matter in any way. It doesn't collide with it, or absorb energy from it. We can't see it or detect it with any of our instruments. We only know it's there because we can see the effect of its gravity.

Read about Henry Cabot Lodge's opposition to the League of Nations and answers the question that follows.

“I have never had but one allegiance—I cannot divide it now. I have loved but one flag and I cannot share that devotion and give affection to the mongrel banner invented for a league. Internationalism, illustrated by the Bolshevik and by the men to whom all countries are alike provided they can make money out of them, is to me repulsive.

“National I must remain, and in that way I like all other Americans can render the amplest service to the world. The United States is the world's best hope, but if you fetter her in the interests and quarrels of other nations, if you tangle her in the intrigues of Europe, you will destroy her power for good and endanger her very existence . . . . We would not have our country's vigour exhausted or her moral force abated, by everlasting meddling and muddling in every quarrel, great and small, which afflicts the world.”

—Henry Cabot Lodge
August 1919

(A) Immigrants to the colonies

(B) Indentured Servants

(C) Prisoners

(D) Enslaved people from Africa

Pleasee!!!!!!!!!

Answers

D. Enslaved people from Africa

Enslaved people from Africa provided the labor that allowed the southern colonies to generate profits.

Slavery played a significant role in the economy of the Southern colonies.The Southern states depended on the slaves to perform work in the fields of cotton plantations. Slavery was the backbone of the economy of the South. African slaves were brought to America as servants and labourers to help the English colonies to prosper and to generate wealth. African Slaves were sold in an auction in the southern states with betting on them.

Therefore we can conclude that enslaved people from Africa were used as labour in southern states.
