Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity

Explanation:

Hydroelectric power is generated from free falling water through a river channel.

The flow of water at a high speed creates water current and the kinetic energy of the water movement spins turbine attached with a generator. This produces a rotating energy which spins the generator and the coil inside.

The magnetic spinning of coiled wire inside the generator produces electric current which is then stored and transmitted through electric power grid lines to supply electric current.

How long does novocaine take to wear off?
Inessa05 [86]
Novocaine is a logal anesthetic agent which is commonly used during dental procedures or other oral processes. This causes numbness of the infected area so that the patients will not feel the pain. This is a local name for procaine which was discovered by the German chemist named Alfred Einhorn in 1905. 

The duration to which we expect the numbness varies to the different factors. The factors include the location of the application, the area, concentration, and presence of other anesthetic chemical. It is expected at least that novocaine will last for 1.5 to 3 hours.

Gnoma [55]

Answer:

4

Explanation:

<em>The number of progeny expected to display the dominant phenotype for both the A and B genes should be  4.</em>

<u>A test cross usually involves crossing an individual whose zygosity is in doubt with an individual that is recessive for both alleles so as to ascertain the zygosity of the former.</u> Hence, for a test cross involving AaBb:

             AaBb     x     aabb

Progeny:

4 AaBb

4 Aabb

4 aaBb

4 aabb

<em>Therefore, the number of progeny expected to display the dominant phenotype for both the A and B genes is 4.</em>
