What is dangerous about living for 7 days on just one can of sardines

Sardines are not not good as they lack nutrient, stored in can with preservatives and also may lead of mercury bio magnification in case of prolonged and continuous consumption.

Step-by-step explanation:

Sardines are the most perishable variety of fish which means that without preservatives in a can these fishes cannot be preserved for long time.

Sardines are consumed because of low mercury content in them as they feed on planktons but due to the use of preservatives in canned fish packages,  food and health association do not recommend  consumption of sardines.

Also, minute quantity of harmful chemicals like mercury causes bio magnification.

Sardines also lack several essential nutrients due to their tight choice of food.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
