Scientists have learned a great deal from studying and using stem cells. "Bird flu diseases" are not involved in stem cell research.

Explanation:

The cells aimed at distinguishing the cells into specific kinds, serve as the possibility of a natural source (renewable) of substitute cell and flesh to cure various diseases named as stem cells. This involve back bone injury, vision loss, burns, cardiac related issues, blood sugar, stroke, and some arthritis.

Avian influenza or bird flu is a viral illness which can kill birds as well as humans and other species who consume them or in contact with them. H5N1 is the most frequently seen form of bird flu.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
