What were two consequences of the French and Indian War? Include the Proclamation
34kurt

Answer:

1. The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American revolution.

2. In the long-term, the Revolution would also have significant effects on the lives of slaves and free blacks as well as the institution of slavery itself. It also affected Native Americans by opening up western settlement and creating governments hostile to their territorial claims.

Answer:

The answer is:

B. Worms consuming the blood from mammals.

Algae isn't causing any harm to the sloth, rather its providing it with camouflage to hide from predators. Both creatures benefits since the algae gets to eat any parasites and other things in the sloths fur, plus they get a free ride and home in the process. The sloth isn't harmed and is helped by the algae since it provides camouflage (mutualism).

Tree frogs aren't causing harm to the trees since they are only using them to hide from predators, the tree serves as protection for the frogs and aren't harmed in the process (commensalism).

Two fish protecting each other from predators aren't harming each other in any way, rather they are protecting each other from another animal that wants to eat them (mutualism).

The worms however are harming the mammals because they are consuming the mammals blood, this is parasitism since one animal is benefiting and the other is harmed.

Hope this helps! :)
