Which form of government is best?
boyakko [2]

Answer:

In this scenario, a representative democracy would be best.

Explanation:

In this situation where the head of state has been engaging in corruption it would be good to have a representative democracy or what is sometimes called indirect democracy.  In this kind of government people vote for their leaders and they are charged with representing them.  The laws in society are therefore representative of the people and the representatives can vote on whether to remove the leader ahead of his term or whether some other sanction is appropriate. There are checks and balances in this kind of system that assures the executive does not gain too much power.  It is also unlikely this leader will be voted in for a third term given his corrupt practices.

laiz [17]

Answer:

Prefrontal cortex.

Explanation:

The prefrontal cortex is an integral part of an individual's cognitive control functioning. It covers the front part of the frontal lobe, where various sensory modalities are integrated.

So, when Jack suffers the trauma to his brain, the alterations to his personality are the effects of the damage in his prefrontal cortex. Since this part of the brain is responsible for one's executive movements like focus, understanding the consequences of one's actions, personality development, decision making, etc, Jack's trauma left him devoid of these abilities.

Thus, his injury is in his brain's prefrontal cortex.

Should disobedient youths be suspended from school? does this solution hurt or help? what would you recommend instead of suspens
cricket20 [7]
Suspension in schools is defined as the mandatory exclusion from the learning environment.  One argument is that children who are "disobedient" in school should not be suspended for behavior because they are usually students who are behind academically and therefore will continue to be further behind the other students.  The achievement gap will continue to widen for these students.

Olenka [21]
The removal of her ovaries has caused the decrease in interest in sexual activities. Ovaries are the most important part of  a female's reproductive system. These produce hormones such as estrogen which is the female's sex hormone. This causes a woman's drive to feel sexually attracted to her partner. Without the production of estrogen in the body, a decrease in interest sexually is experienced.
