Could life as we know it exist on Earth if air containd only oxygene?Explain your reasoning
Kisachek [45]

Answer:

Oxygen in it's purest form is a deadly gas that would kill is almost instantly. It is the cause for most (if not all) cases of combustion. We breath in two molecules of oxygen, which stabilizes the compound and allows us to dispel carbon dioxide safely. It only comprises a small part of the atmosphere though. The air is made up of around 93% nitrogen, which is vital for the survival of certain species on earth. There is also a carbon cycle in the air which will be destroyed, given that only oxygen was in the atmosphere.

If your carbohydrate consumption was low, then the process of making ATP would quickly diminish. Carbohydrates are the main source of energy to cells, and it's because of them that we can make ATP.

This would affect your cells by slowing them down, which ultimately slows you down as a whole. If it gets too serious, death can occur.

Elderly persons have the basic genes they had as newborns, but _____ can change the expression of those genes as time goes on
pychu [463]
The correct answer is methylation.
This process refers to the addition of methyl groups to the DNA molecule, when the activity of such DNA segments is slightly altered. The more we age, the less methylation there is, which is why the genes of the elderly are different from those of young people.

Classify the actions as either discretionary spending or an automatic stabilizer.
prohojiy [21]

Answer:

a. Automatic stabilizers

b. Discretionary spending

c. Automatic stabilizers

d. Discretionary spending

e. Discretionary spending

f. Discretionary spending

g. Discretionary spending

h. Automatic stabilizers

i. Automatic stabilizers

Explanation:

a. A bill to increase unemployment benefits is discretionary spending because the government has to make a decision to change something; it does not happen automatically as the economy changes.

b. Cuts in government spending to balance the budget are also a decision that is made that does not happen automatically.

c. A law to increase Medicare coverage does not happen automatically and requires action by the government.

d. Tax cuts to stimulate spending must be written into effect. Since the tax rate is set and does not change by itself, it is discretionary spending.

e. Increasing tax rates also does not happen by itself and must be changed by the government, making it discretionary spending as well.

f. Increased tax payments from economic growth is an automatic stabilizer. As the economy grows, people have more income and firms have more profits. Both therefore pay more in taxes, increasing tax payments automatically.

g. More spending on welfare due to more applicants is an automatic stabilizer too. As more people apply for and receive welfare due to a bad economy, government spending will automatically increase.

h. Tax revenue depends on the level of economic activity. When people are laid off or earn less during a recession, tax revenue falls. Likewise, a decrease in corporate profits automatically decreases taxes owed.

i. More spending on unemployment benefits due to increased layoffs is automatic because when more people are laid off and apply for unemployment benefits, spending automatically increases.
